Changes in body temperature throughout the day. Normal temperature

It would seem that there is no doubt - the normal temperature is 36.6 ° Celsius. So we have hardened from early childhood. But is it really so?

How does body temperature change depending on various factors?

It turns out that scientists have long been engaged in experiments to measure the temperature of the human body in various situations. And it turned out that 36.6 ° Celsius is an extremely unstable value. In fact, the temperature varies greatly depending on factors such as environmental conditions, human activity at one time or another, food intake, sleep or wakefulness, and even emotions or the part of the body where the measurement is taken.

So, if the air in the room is warmed up to about 20 °, then when measuring, you can see that the temperature on the thigh muscle will be 35 °, on the calf muscle - 33 °, and in the center of the foot - only 27-28 °. Under the same measurement conditions, it can be seen that the temperature in the rectum will be 37 °, and in the liver - 38 °. And even in the brain there are temperature fluctuations of 1 ° or more.

In addition, in women, the temperature changes during the menstrual cycle, depending on the level of sex hormones. And it should be noted that all, without exception, people, the temperature may rise by 1-2 ° during intense physical work.

How does body temperature depend on age?

The body temperature in children is very unstable. It changes upward during crying or screaming, as well as during active games in the fresh air or during meals.

But in older people, the normal temperature can drop to 35 °. This is due to the fact that with aging, metabolism slows down, so the body begins to rebuild to a lower temperature level.

Scientists have found that in the usually measured temperature place - the armpit, during the day the temperature changes by a whole degree. At the same time, the maximum temperature occurs at 4-6 pm, and the minimum - at 3-4 am. This condition is called the circadian rhythm of the body's biological clock.

What to do when the temperature rises

Usually, having noticed an increase in temperature, we begin to worry if it is caused by some kind of disease and try to take all possible measures to reduce it. It should be noted that an increase in temperature indicates a natural protective reaction of the body in the event of the introduction of any infection that irritates the brain centers responsible for thermoregulation.

An increase in body temperature is much worse for microbes than for humans, so you should not abuse antipyretic drugs. They should be used at temperatures above 38.5-39 °, as well as with individual intolerance to high temperatures or severe intoxication of the body with vomiting that can lead to dehydration.

First of all, it is necessary to organize an abundant drink for a person with a high temperature. A large amount of fluid entering the body contributes to increased perspiration and the elimination of toxins in the urine, thereby lowering the temperature.

But if the temperature has already risen above 39 °, antipyretic drugs should be used.

It is important to identify the correct cause of the appearance of a high temperature, and only a doctor will help you with this!

The optimal time for measuring the normal body temperature of an adult healthy person is the middle of the day, while the subject should be at rest before and during measurements, and the microclimate parameters should be within the optimal range. Even under these conditions, the temperature may vary slightly from person to person, which may be due to age and gender.

During the day, the metabolic rate changes, and with it the temperature at rest changes. During the night, our bodies cool down, and in the morning the thermometer will show the minimum values. By the end of the day, metabolism accelerates again, and the temperature rises by an average of 0.3-0.5 degrees.

In any case, normal body temperature should not fall below 35.9 ° C and rise above 37.2 ° C.

Very low body temperature

Body temperature below 35.2 ° C is considered very low. Possible causes of hypothermia include:

• Hypothyroidism or decreased thyroid function. The diagnosis is established on the basis of blood tests for the hormones TSH, svT 4, svT 3. Treatment: prescribed by a doctor as an endocrinologist (hormone replacement therapy).
• Violation of the centers of thermoregulation in the central nervous system. This can happen with injuries, tumors and other organic brain damage. Treatment: elimination of the cause of brain damage and rehabilitation therapy after injuries and surgeries.
• Reduction of heat production by skeletal muscles, for example, when their innervation is disturbed as a result of a spinal injury with damage to the spinal cord or large nerve trunks. A decrease in muscle mass due to paresis and paralysis can also lead to a decrease in heat production. Treatment: drug treatment is prescribed by a neurologist. In addition, help: massage, physiotherapy, exercise therapy.
• Prolonged fasting. The body simply has nothing to produce heat from. Treatment: restoring a balanced diet.
• Dehydration of the body. All metabolic reactions take place in the aquatic environment, therefore, with a lack of fluid, the metabolic rate inevitably decreases, and the body temperature drops. Treatment: timely compensation for fluid loss during sports, when working in a heating microclimate, in diseases of the gastrointestinal tract, accompanied by vomiting and diarrhea.
• organism. At very low ambient temperatures, thermoregulatory mechanisms may not cope with their function. Treatment: gradual warming of the victim from the outside, hot tea.
• Strong alcoholic intoxication. Ethanol is a neurotropic poison that affects all brain functions, including thermoregulatory functions. Help and treatment: call an ambulance. Detoxification measures (gastric lavage, intravenous infusion of saline), the introduction of drugs that normalize the function of the nervous and cardiovascular systems.
• Effects of elevated levels of ionizing radiation. A decrease in body temperature in this case is a consequence of metabolic disorders as a result of the action of free radicals. Help and treatment: detection and elimination of sources of ionizing radiation (measurement of levels of radon isotopes and EDR of gamma radiation in living quarters, occupational safety measures in production where radiation sources are used), treatment is prescribed after confirmation of the diagnosis (drugs that neutralize free radicals, restorative therapy),

With a decrease in body temperature to 32.2 ° C, a person falls into a state of stunnedness, at 29.5 ° C, loss of consciousness occurs, with cooling below 26.5 ° C, the death of the body is likely to occur.

Moderately low temperature

Moderately lowered body temperature is considered in the range from 35.8 ° C to 35.3 ° C. The most likely causes of mild hypothermia are as follows:

• , asthenic syndrome or seasonal. In these conditions, a deficiency of some micro and macro elements (potassium, calcium, phosphorus, sodium, chlorine, magnesium, iron) can be detected in the blood. Treatment: normalization of nutrition, intake of vitamin and mineral complexes, adaptogens (immunal, ginseng, Rhodiola rosea, etc.), fitness classes, development of relaxation methods.
• Overwork due to prolonged physical or mental stress. Treatment: adjusting the work and rest regimen, taking vitamins, minerals, adaptogens, fitness, relaxation.
• Wrong, unbalanced diet for a long time. Physical inactivity aggravates the decrease in temperature and slows down metabolic processes. Treatment: normalization of the diet, proper diet, balanced diet, intake of vitamin and mineral complexes, increased physical activity.
• Hormonal changes during pregnancy, menstruation, menopause, decreased thyroid function, adrenal insufficiency. Treatment: Prescribed by a physician after establishing the exact cause of hypothermia.
• Taking drugs that reduce muscle tone, such as muscle relaxants. In this case, skeletal muscles are partially turned off from thermoregulatory processes and produce less heat. Treatment: consult your doctor for advice about a possible replacement or interruption of medication.
• Dysfunction of the liver, leading to a change in carbohydrate metabolism. The condition will help to detect a general blood test, a biochemical blood test (ALAT, ASAT, bilirubin, glucose, etc.), an ultrasound of the liver and bile ducts. Treatment: prescribed by a doctor after carrying out appropriate diagnostic procedures. Drug therapy aimed at the cause, detoxification measures, taking hepatoprotectors.

Subfebrile body temperature

This is a slight increase in body temperature when its values ​​are in the range of 37 - 37.5 ° C. The reason for such hyperthermia can be completely harmless external influences, common infectious diseases and diseases that pose a serious threat to life, for example:

• Intense sports or hard physical labor in a warming microclimate.
• A visit to the sauna, steam bath, solarium, taking a hot bath or shower, some physiotherapy procedures.
• Eating hot and spicy foods.
• Acute respiratory viral infections.
• (the disease is accompanied by an increase in the function of the thyroid gland and an acceleration of metabolism).
• Chronic inflammatory diseases (inflammation of the ovaries, prostatitis, inflammation of the gums, etc.).
• Tuberculosis is one of the most dangerous reasons for the frequent rise in body temperature to subfebrile values.
• Oncological diseases are a serious threat to life and often lead to a slight increase in body temperature in the early stages of development.

If the temperature does not exceed 37.5 ° C, you should not try to reduce it with the help of medicines. First of all, you need to see a doctor so that the overall picture of the disease is not blurred.

If the temperature does not return to normal for a long time or episodes of subfebrile condition are repeated from day to day, you should definitely go to the doctor, especially if it is accompanied by weakness, unexplained weight loss, swollen lymph nodes. Additional examination methods may reveal more serious health problems than you think.

Febrile temperature

If the thermometer shows 37.6 ° C or higher, then in most cases this indicates the presence of an acute inflammatory process in the body. The focus of inflammation can be localized anywhere: in the lungs, kidneys, gastrointestinal tract, etc.

In this case, most of us try to immediately bring down the temperature, but such a treatment tactic is far from always justifying itself. The fact is that an increase in body temperature is a natural protective reaction of the body, aimed at creating conditions unfavorable for the vital activity of pathogens.

If the sick person does not have chronic diseases and if the fever is not accompanied by seizures, then it is not recommended to reduce the temperature to 38.5 ° C with medication. Treatment should begin with drinking plenty of fluids (1.5 - 2.5 liters per day). Water helps to reduce the concentration of toxins and their excretion from the body in urine and sweat, as a result, the temperature drops.

At higher thermometer readings (39 ° C and above), you can start taking antipyretics, that is, drugs that lower the temperature. Currently, the range of such products is quite large, but perhaps the most famous drug is aspirin, made on the basis of acetylsalicylic acid.

Body temperature is an indicator of the thermal state of the body. Thanks to it, the relationship between the production of heat of internal organs, heat exchange between them and the outside world is reflected. At the same time, temperature indicators depend on the age of a person, time of day, the impact of the surrounding world, health status and other characteristics of the body. So what should be the body temperature of a person?

People are accustomed to the fact that with changes in body temperature, it is customary to talk about health problems. Even with a slight hesitation, a person is ready to sound the alarm. But everything is not always so sad. Normal human body temperature ranges from 35.5 to 37 degrees. At the same time, the average indicator in most cases is 36.4-36.7 degrees. I would also like to note that temperature indicators can be individual for everyone. The normal temperature regime is when a person feels completely healthy, able to work and there is no disruption in metabolic processes.

What is the normal body temperature in adults also depends on what nationality the person is. For example, in Japan, it is kept at 36 degrees, and in Australia, the body temperature rises to 37 degrees.

It is also worth noting that the normal human body temperature can fluctuate throughout the day. In the morning hours, it is lower, and in the evening it rises significantly. Moreover, its fluctuation during the day can be one degree.

Human temperature is divided into several types, which include:

1. lowered body temperature. Its indicators fall below 35.5 degrees. This process is called hypothermia;
2. normal body temperature. Indicators can range from 35.5 to 37 degrees;
3. increased body temperature. It rises above 37 degrees. Moreover, it is measured in the armpit;
4. subfebrile body temperature. Its limits range from 37.5 to 38 degrees;
5. febrile body temperature. Indicators range from 38 to 39 degrees;
6. high or pyretic body temperature. It rises to 41 degrees. This is a critical body temperature, which leads to disruption of metabolic processes in the brain;
7. hyperpyretic body temperature. A fatal temperature that rises above 41 degrees and is fatal.

Also, the internal temperature is classified according to other types in the form:

• hypothermia. When the temperature readings are below 35.5 degrees;
• normal temperature. It fluctuates between 35.5-37 degrees;
• hyperthermia. The temperature is above 37 degrees;
• feverish condition. The indicators are raised above 38 degrees, while the patient has chills, blanching of the skin, a marble mesh.

Body temperature measurement rules

All people are accustomed to the standard that temperature readings should be measured in the armpit. To complete the procedure, you need to follow several rules.

1. The armpit should be dry.
2. Then a thermometer is taken and gently shaken off to a value of 35 degrees.
3. The tip of the thermometer is located in the armpit and is pressed tightly by the hand.
4. You need to keep it from five to ten minutes.
5. After that, the result is evaluated.

You should be extremely careful with a mercury thermometer. You cannot break it, otherwise mercury will pour out and release harmful vapors. It is strictly forbidden to give such things to children. You can have an infrared or electronic thermometer as a replacement. Such devices measure temperature in a matter of seconds, but the values ​​from mercury may differ.

Not everyone thinks that the temperature can be measured not only in the armpit, but also in other places. For example, in the mouth. With this measurement method, normal readings will be in the range of 36-37.3 degrees.

How to measure the temperature in the mouth? There are several rules.
To measure the temperature in the mouth, you need to be calm for five to seven minutes. If there are dentures, braces or plates in the mouth, then they should be removed.

After that, the mercury thermometer must be wiped dry and placed under the tongue on either side. To obtain the result, it must be held for four to five minutes.

It is worth noting that oral temperature differs significantly from measurements in the armpit. Temperature measurements in the mouth may show a result higher by 0.3-0.8 degrees. If an adult doubts the indicators, then a comparison should be made between the temperature obtained in the armpit.

If the patient does not know how to measure the temperature in the mouth, then the usual technology can be followed. During the procedure, it is worth following the execution technique. The thermometer can be installed both behind the cheek and under the tongue. But it is strictly forbidden to clamp the device with your teeth.

Decreased body temperature

After the patient has found out what temperature he has, it is necessary to determine its nature. If it is below 35.5 degrees, then it is customary to talk about hypothermia.

The internal temperature can be low for several reasons, which include:

• weakened immune function;
• severe hypothermia;
• recent illness;
• endocrine system diseases;
• the use of certain medications;
• low hemoglobin;
• failure in the hormonal system;
• the presence of internal bleeding;
• intoxication of the body;
• chronic fatigue.

If the patient's internal temperature is very low, then he will feel weakness, loss of strength and dizziness.
To increase the temperature at home, you need to put your feet in a hot foot bath or on a heating pad. After that, put on warm socks and drink hot tea with honey, herbal infusion.

If the temperature indicators decrease gradually and reach 35-35.3 degrees, then we can say:

• about simple fatigue, strong physical exertion, chronic lack of sleep;
• about improper nutrition or adherence to a strict diet;
• about hormonal disruption. Occurs at the stage of gestation, with menopause or menstruation in women;
• about disorders of carbohydrate metabolism due to liver diseases.

Increased body temperature

The most common phenomenon is an increased body temperature. If it stays at levels from 37.3 to 39 degrees, then it is customary to talk about an infectious lesion. When viruses, bacteria and fungi enter the human body, severe intoxication occurs, which is expressed not only in an increase in body temperature, but also in a runny nose, tearing, coughing, drowsiness, and a deterioration in the general condition. If the internal temperature rises above 38.5 degrees, then doctors advise taking antipyretic drugs.

The onset of temperature can be observed with burns and mechanical injuries.
In rare situations, hyperthermia is observed. This condition is caused by an increase in temperature indicators above 40.3 degrees. If such a situation arises, it is necessary to call an ambulance as soon as possible. When the indicators reached 41 degrees, it is customary to talk about a critical condition that threatens the patient's future life. At a temperature of 40 degrees, an irreversible process begins to occur. There is a gradual destruction of the brain and deterioration of the work of internal organs.

If the internal temperature is 42 degrees, then the patient dies. There are cases when the patient experienced such a condition and survived. But their number is small.

If the internal temperature rises above the burrow, then the patient manifests symptoms in the form of:

1. tiredness and weakness;
2. general painful condition;
3. dryness of the skin and lips;
4. mild or severe chills. Depends on temperature indicators;
5. pain in the head;
6. aches in muscle structures;
7. arrhythmias;
8. decrease and complete loss of appetite;
9. excessive sweating.

Every person is different. Therefore, everyone will have their own normal body temperature. Someone, with indicators of 35.5 degrees, feels normal, and with an increase to 37 degrees, they are already considered sick. For others, even 38 degrees may be the limit of the norm. Therefore, it is worth focusing also on the general condition of the body.

At the same time, temperature indicators depend on the age of a person, time of day, the impact of the surrounding world, health status and other characteristics of the body. So what should be the body temperature of a person?

Types of temperature indicators

Therefore, it is worth focusing also on the general condition of the body.

Body temperature diagnostics

It would seem, what can be difficult here? An increased body temperature indicates a disease, the need to see a doctor, etc. Did you know that temperature changes during the day can tell a lot about the nature of the disease?

First you need to correctly measure your body temperature. It also has its own rules, violation of which can lead to incorrect results.

Today, a mercury thermometer is used to measure body temperature. A column of mercury, expanding from heat, rises up a thin transparent tube, next to which there is a scale with divisions. One division is 0.1 degrees. Such a thermometer can measure temperatures from 35 to 42 degrees. Having risen, the column of mercury does not fall until the thermometer is shaken.

Before measuring the temperature, shake the thermometer vigorously so that the mercury column drops to 35 ° C. Examine the post carefully. There should be no breaks in it, otherwise the thermometer will never show the correct temperature!

It is known that in some countries temperature (including body temperature) is measured in Fahrenheit. Fahrenheit is degrees Celsius multiplied by 1.8 + 32. The difference is related to that. what value was taken by scientists as absolute zero.

More often, the temperature is measured in the submuscular cavity. Before measuring, it must be wiped dry, otherwise moisture, evaporating from the surface of the skin, will cool it, and the temperature will be lower than it actually is. The thermometer must be positioned so that the mercury reservoir is completely covered by the skin. The hand must be pressed to the body and held for 10 minutes. Then remove the thermometer and look at the result.

The armpit is not the only place to measure temperature. For example, if a person is weak and cannot hold the thermometer himself, the temperature in the groin fold can be measured. In addition, temperature is also measured in the rectum, vagina and sometimes in the mouth.

In order to measure the temperature in the rectum, you need to thoroughly wash the thermometer, lubricate its end with petroleum jelly and carefully insert it into the anus. After measuring, the thermometer must be washed again and wiped with alcohol or cologne.

It must be remembered that the body temperature in the armpit, rectum or vagina will never be the same. In the rectum, it will always be higher, but this difference should not exceed 0.8-1 degrees. If the difference exceeds these figures, this indicates inflammation of the internal organs, which means that an urgent need to consult a doctor.

Everyone knows the normal temperature of the human body. It averages 36.6 degrees, and can fluctuate between 36.2-37 degrees. The temperature of 37 degrees is already considered elevated. Body temperature depends on environmental conditions, health status and time of day. In the evening, it is usually higher than in the morning (sometimes it can even reach 37 ° C).

When a person is sick, the temperature should be measured at least 2 times a day: in the morning and in the evening. It is advisable to record the results, even if the numbers correspond to the norm. It is very convenient to put them in a special temperature sheet, which is easy to do on your own. To do this, draw two perpendicular axes. Set aside time on the horizontal (date, morning and evening), and on the vertical - read the thermometer (with an accuracy of 0.1 degrees). Every time you measure the temperature, put a point in accordance with the results obtained. Then connect the points with straight lines. So you get a temperature graph (temperature curve), which is much easier to navigate by than just a sheet of written results. Different diseases give different temperature curves because the measurement data is always different. This can be a good diagnostic aid.

Oddly enough, almost the worst of all a person feels at a slightly elevated body temperature (37.2 - 37.5 degrees).

Persistent fever

With this type of fever, tempurature is always elevated (even in the morning it exceeds 37 degrees), but in the morning it is still lower than in the evening. During the day, the temperature difference is no more than 1 degree. At the same time, the morning temperature can be relatively low (37.2-38 degrees). This is how body temperature fluctuates with croupous pneumonia, as well as with typhoid fever.

Weakening fever

Morning temperature is above 37 ° C, during the day it rises slightly. Evening temperatures are always higher than morning temperatures. This type of fever can occur with milder forms of pneumonia, purulent diseases, tuberculosis.

Wasting (hectic) fever

With this form of fever, the morning temperature, as a rule, turns out to be normal or slightly increased (no more than 37 - 37.1 degrees), and the evening temperature is much (2 - 4 degrees) higher than it. Since the temperature rises sharply, at this moment a person feels a strong chill, headache and muscle pain. At night, the tempurature can also drop sharply, while a person sweats a lot, his blood pressure drops, which can even lead to loss of consciousness.

This type of fever occurs in severe diseases: advanced pulmonary tuburculosis, severe purulent diseases, and sepsis.

Intermittent fever

In order to identify this rather rare form of fever, it is necessary to collect data on temperature changes over several days. The morning temperature is always normal, for several days in the evening it can rise slightly (no more than 1 degree), and then subside again. Once every 2-3, less often 4 days a day the temperature rises sharply by 2-4 degrees, and then drops just as sharply, after which “calm” days come again. If you draw a chart, then high teeth - candles - will periodically appear on it. This fever occurs with malaria.

Wrong fever

With an irregular fever, there is no pattern in temperature changes. She then rises to high numbers, then remains normal. The only “rule” that is observed here is that the morning temperature is always lower than the evening one. This type of fever can be a sign of rheumatism, tuberculosis, sepsis, and other serious illnesses.

According to legend, Fever is one of the twelve sisters of Herod, along with Jaundice, Mayhem, Znobuha, Shake and other diseases. Why exactly King Herod "got" such relatives is clear to anyone who is familiar with the Gospel stories.

Reverse fever

There is also no system in the change in temperature with this type of fever, however, it is characterized by the fact that the morning temperature is higher than the evening one. Such a fever occurs with tuberculosis, brucellosis.

Some illnesses last for weeks or months. With regular measurement and recording of temperature, two more forms of fever are distinguished, which can be combined with the above.

Wave-like fever

Morning tempurature gradually increases from day to day, and then also slowly decreases. Evening measurement data are changed according to the same principle, and the differences in values ​​may be different. The graph clearly shows small waves - differences between morning and evening temperatures and larger waves - gradual changes in the "reference point" - morning temperature.

Such a fever occurs with brucellosis and lymphogranulomatosis (systemic damage to the lymphatic system).

Recurrent fever

For several days, both the trench and evening temperatures remain normal (or the evening may be slightly elevated), then the temperature rises sharply, and for several days both the morning and evening numbers remain high, after which the temperature drops again. Small fluctuations during the day (small waves) persist.

This fever occurs with relapsing fever.

Why does the temperature rise to 37 degrees in the evening? Causes and diagnosis

And sometimes the body temperature remains normal throughout the day, but in the late afternoon it invariably rises. Such a phenomenon does not always indicate the development of the disease, but it nevertheless speaks of certain changes in the human body. In some people, such changes generally become a common condition, because this is how their thermoregulatory system functions. And yet you should very closely consider the reasons for the appearance of such numbers on the thermometer.

Every evening the temperature rises to 37 degrees in adults and children for a variety of reasons. The indicators will be influenced by various factors: physiological and pathological. Of course, if you complain about your own health, you should consult a doctor. But sometimes a temperature of 37.1 (in the evening) does not mean something terrible, but is a variant of the norm.

But if these symptoms continue for a long time, you need to see a doctor. Most likely, this condition indicates an immune response to a certain threat or trouble.

What can affect the temperature change in the evening?

A person rarely resorts to using a thermometer if there are no additional health complaints and signs of illness. But, having carried out periodic measurements, you may be surprised that there is a temperature of 37 in the evening, but not in the morning. Thermometer readings are influenced by many factors:

• time of day (it is known that in the morning the thermometer readings are lower than in the evening, and during deep sleep, the lowest values ​​are noted);
• the rhythm of life (for people with an active lifestyle, the thermometer readings are always higher);
• type of measuring device (it is generally accepted that electronic thermometers have an error, in contrast to mercury devices);
• season and weather conditions (in winter, the temperature naturally rises, and in summer it becomes lower);
• physiological and pathological conditions.

Physiological conditions that increase temperature

Hyperthermia does not always arise due to a certain threat. Very often it is a consequence of overload or hormonal changes in the body.

This can happen due to the ingestion of hot or spicy food, nervous tension, and the prescription of certain medications.

Sometimes such figures are not considered a pathology at all, but only a borderline state of the norm. Only in the case of a strong increase or an unacceptably long period of hyperthermia is a comprehensive examination of the patient's body prescribed.

Among women

Many women have a periodically high body temperature. This is why this is happening. During the menstrual cycle, hormones are constantly produced.

On certain days, the release of some substances becomes more, while others - less. Immediately after ovulation (the release of the egg from the ovary), progesterone comes into play.

This hormone is very important for maintaining the second phase of the cycle and the development of pregnancy. Thanks to him, relaxation of smooth muscles occurs. Also, progesterone affects thermoregulation, reduces the rate of heat transfer.

Before menstruation, a woman may notice that her body temperature has increased by fractions of a degree.

As soon as bleeding begins, the progesterone level will decrease and the thermometer readings will return to normal. If pregnancy has occurred, then increased values ​​may persist for several months until the placenta is formed. For expectant mothers, it is considered the norm if the thermometer shows 37-37.2 degrees.

A rise in temperature in the evenings is usually explained by a sharp hormonal change in the body, toxicosis during pregnancy, an increase in metabolic intensity, reflex influences when drinking alcohol or the usual processes of thermoregulation.

The reasons why the temperature rises in the evening 37:

• during premenstrual syndrome
• while carrying a child
• when feeding a baby
• at ovulation
• shortly after the birth of children
• with menopause
• after eating too much and too much
• with excessive consumption of strong alcoholic beverages
• with significant overheating in the sun, etc.

For some women, this temperature is generally normal, accompanying them all their lives. For other ladies, in the evening, the numbers often change due to increased fatigue or severe nervous tension.

In men

Representatives of the stronger sex also often complain that the temperature rises to 37 in the evening without symptoms. This may be due to hypothermia or overheating, injury, nervous strain. Hyperthermia can occur due to excessive consumption of spicy food or hobby for alcoholic beverages.

The temperature can jump in the evening due to significant muscle strain after hard physical work or increased sports training.

The most commonplace reason can be a long reception of a too hot bath or shower, a long sleep in a chair near the battery itself, a very warm dressing gown or suit.

In old people, temperature fluctuations can have their own characteristics. During the day, for example, there will be some hypothermia, and by the evening the numbers will creep to around 37 degrees.

In addition, in men, as in women, such indicators can be quite normal and correspond to their physiological norm.

In children

The child often causes severe anxiety to his parents because of the temperature that has jumped in the evening.

Nevertheless, it is worth noting that in children under five years of age, due to their imperfect thermoregulation, 37.2 - 37.3 degrees can be considered a normal temperature.

Most often, an increase in temperature at night occurs soon after an infection or other childhood illness. The baby's immunity has not yet fully strengthened, so his circulatory system reacts with an increased release of lymphocytes, accompanied by hyperthermia.

This is a normal reaction, indicating that the defenses of the child's body are on guard for his health.

The rise in temperature in the evening to 37 in a child can also be explained by the most common reasons:

• Overly active games
• too warm clothes
• vaccine reaction
• teething
• hot drink at night
• a blanket too warm
• change of biorhythms
• hearty dinner
• unstable metabolism, etc.

In newborns and premature babies, a temperature of thirty-seven degrees in the evening is not uncommon and it is associated with the formation of normal thermoregulation processes in the baby's body.

Such reasons are the most common and are faced by all parents.

In an overly sensitive child, the temperature can rise even with strong crying or watching an interesting movie.

The baby's digestive system can also respond with an abundant release of enzymes and active intestinal work, which causes the temperature to rise in the evening to 37.

Therefore, the temperature of children is measured only after special training. The thermometer should be installed at the same time under the same conditions.

Sufficient time should pass after the cessation of all activity, the child should be calm and relaxed. The baby's armpit should be allowed to dry completely, and he should not be allowed to sweat himself. It is advisable to measure the temperature before dinner and water procedures.

Eating

Another physiological reason for the increase in thermometer readings is the meal. It is recommended to measure the temperature no earlier than half an hour after a meal. The fact is that while eating, the body spends heat, so it constantly compensates for it.

A noticeable increase in temperature occurs in people with a good metabolism. Most people do not feel these changes, but if you take your temperature right after eating, you will be very surprised.

Since a more voluminous meal occurs in the evening (dinner), then the temperature rise at this time of the day becomes more pronounced.

Overwork

It is known that at night the thermometer readings become much lower. This is facilitated by a decrease in activity and low energy consumption. However, in the evening, the indicators, on the contrary, become higher. This happens due to overwork, overexertion, stress.

There is such a thing as chronic fatigue syndrome. In people with this diagnosis, the temperature can rise for no reason throughout the day.

Most often in the evening there is a temperature of 37-37.2 and weakness, headache. If during rest and deep sleep the indicators do not become lower, then you should think about the presence of a pathological cause of this condition.

Reasons for the rise in temperature

Not always, when a thermometer records thirty-seven, it only speaks of harmless functional reasons. Often, such figures indicate the development of a disease.

Such surges may be the first symptom:

• Helminthiasis
• inflammatory process in the body
• introduction of infection
• development of malignant neoplasm
• cardiovascular disease
• allergies
• neurological diseases
• rheumatism
• arthritis
• endocrine diseases
• development of mental pathologies

When an increase in body temperature is recorded in the evening, the reasons can be very different. They are capable of being associated with intoxication with cellular decay products, the fight against pathogenic microorganisms or impaired neuromuscular conduction.

Infection with infectious diseases is also possible, so a visit to a doctor in this case is mandatory.

Pathological conditions

If a person's temperature rises to 37 in the evening, then this may be a wake-up call. There are many pathological causes of this condition, but they usually all have additional signs. Busy people with active lifestyles may not even notice them.

Colds

The most common symptom of a cold is precisely an increase in temperature values. In this way, the human body is trying to cope with the causative agent of the infection. It is known that viruses die at a thermometer mark of 38 degrees. Therefore, you should not bring down the temperature to 37. Let your body eliminate the infection and form immunity on its own.

Consequences of infection

Many infectious diseases occur with fever. But what if you are already healthy and it continues to rise? Such an outcome is also possible. It is in the evening that an increase in thermometer values ​​is noticeable.

Especially often, such symptoms are due to chickenpox, acute intestinal infection, bacterial pathologies. Do not worry, the body will recover its strength in the near future. Such temperature indicators do not require the use of antipyretics. After a night's rest, they bounce back on their own.

Blood pressure

Hypertensive patients often complain that they have a high body temperature. Such a natural consequence of high blood pressure cannot be called natural, but it is not entirely correct to consider it pathological. As soon as the patient brings blood pressure back to normal, the thermometer shows smaller numbers.

Hypotensive patients, on the other hand, have a low body temperature. For some people, it drops below the 36-degree mark. It is very important not to miss the moment here. But if this condition does not cause discomfort, then you can not try to fix it.

This abbreviation stands for vegetative vascular dystonia. Until now, this disease remains not fully understood. Many doctors refute it, saying that a person is dealing with chronic fatigue syndrome. One way or another, with vegetative dystonia, an increase in thermometer readings occurs. A person can note that the temperature is 36 in the morning and 37 in the evening.

Oncological pathologies

It is the evening rise in thermometer values ​​that often makes a person turn to specialists. During the examination, tumor processes can be detected.

Benign neoplasms often do not make themselves felt like a symptom. But the multiplication of cancer cells affects the lymphatic system, so a slight increase in the indicators of a mercury meter is the first alarm bell.

Immune diseases

Any deviations in the work of the immune system and the protective functions of the body affect the temperature values. They become higher with the following pathologies:

1. allergy;
2. rheumatic diseases;
3. blood pathology;
4. systemic deviations.

Many diseases develop due to the increased immune function of the body, which provokes inflammation of a different nature.

What is subfebrile condition, and how to deal with it?

Subfebrile condition is called an unreasonable increase in the temperature values ​​of the human body. In such cases, the indicators do not exceed 37.5 degrees.

The temperature lasts for months or even years. This distinguishes it from the course of acute pathological diseases or physiological reasons for the increase.

The main sign of subfebrile condition is that a person has an elevated body temperature. This disease accompanies:

• increased fatigue;
• drowsiness and weakness;
• decreased appetite;
• redness of the skin;
• disorders of the digestive system;
• increased sweating;
• fast pulse;
• neuroses and insomnia.

Both a specialist and the patient himself can diagnose the problem in advance. But with subfebrile condition, more research is needed. To do this, consult a doctor and find out why the temperature rises to 37 in the evening.

Diagnostics for subfebrile condition

Before making a diagnosis, a specialist must examine the patient. The state of the mucous membranes, the work of the respiratory system is studied, the organs of the abdominal cavity are palpated.

Defects of joints, lymph nodes are revealed. In women, a gynecological examination and palpation of the mammary glands are performed, the menstrual cycle is studied. The collection of anamnesis is carried out in several stages.

The doctor determines the following:

1. whether there were surgical interventions or injuries in the recent past (in women - childbirth and abortion);
2. what infectious diseases were transferred during life and whether there are chronic pathologies (special attention is paid to diabetes, HIV, liver and blood diseases);
3. the possibility of hepatitis and bacterial endocarditis.

Usually, already at the stage of examination, the specialist is struck by a rash on the body, discoloration of the skin, uncharacteristic discharge or formations.

Therefore, to confirm his hypothesis, he prescribes a series of tests showing the state of the blood picture, the possible presence of severe infectious chronic diseases or helminthic invasion.

For this, the specialist will send the patient for laboratory tests.

To clarify the reason why he always has a temperature of 37 in the evening, you need to go through:

• clinical and biochemical blood test
• four mandatory tests (HIV, syphilis, hepatitis B and C)
• allergens panel
• general urine analysis
• analysis of feces for eggs, worms and protozoan cysts
• sputum microscopy
• discharge of the urethra and genitals
• biopsy
• spinal cord puncture.

The results obtained help to identify helminthiasis, inflammation or allergic reactions.

For the purpose of differential diagnosis, it is also necessary to do fluorography, radiography, ultrasound scanning, ECG, EEG, CT, MRI, as well as conduct special targeted studies. All this quickly allows you to identify tuberculosis, diseases of the heart, blood vessels, liver and kidneys, malignant neoplasms, which often cause an increase in temperature in the evening.

The specialist receives the final confirmation of the diagnosis by conducting instrumental studies. For this, mammography, FGDS, angiography, ultrasonography, etc. are used.

They accurately enough allow to identify the disease, due to which there is a regular rise in temperature, as they show the state of the patient's internal organs. In addition, they allow the general picture of the disease to be correlated with an altered thermal regime.

Let's summarize

An increase in body temperature in the evening can be caused by many reasons. If you have observed an increase in thermometer readings for a long time, then this is a serious reason for an examination. Don't ignore your own complaints. Be sure to see your doctor and find out why you have a fever in the evening.

What is the normal body temperature in a person: the norm in an adult

Thermoregulation is rightfully considered one of the most important features of the human body.

The body's temperature is maintained by the forces of the body at the required level, and is responsible for its ability to generate heat and exchange with the environment.

During the day, body temperature can vary, but only slightly.

This process is associated with the metabolic rate, for example, in the morning it is lower, and in the evening it rises about a degree.

It is worth finding out what is the normal body temperature in an adult, and what types are there? How is the body temperature measured correctly in the armpit, in the mouth?

What does norm mean?

So, what is the normal temperature? It is generally accepted that the temperature of the human body is exactly 36.6 degrees. Slight deviation to one side or the other is allowed.

Based on the human condition, the surrounding climatic conditions and time of day, as well as other parameters, the body temperature can be from 35.5 to 37.4 degrees. It should be noted that the average temperature regime for women is higher, in contrast to men - by 0.5 degrees.

In the armpit, the body temperature should be 36.3-36.9, in the mouth - 36.8-37.3, in the rectum 37.3-37.7, and this is a normal temperature.

An interesting point is that the average body temperature can differ depending on the nationality. For example, the Japanese have an average of 36 degrees, while the Australians have all 37.

Throughout the day, a person's body temperature can fluctuate around one degree. The lowest body temperature occurs in the morning, and the highest in the late afternoon.

In females, body temperature can fluctuate depending on the menstrual cycle. There are people for whom a temperature of 38 is normal, and is not a symptom of the development of the disease.

Every organ in the human body also has its own temperature. And what is the normal temperature?

The norm is different for everyone. The internal organ is the liver - 39 degrees, the kidneys and stomach should be 1 less.

How to measure the temperature correctly?

To correctly measure the temperature in the armpit, you need to follow these recommendations:

1. Make sure that the armpit is dry.
2. Take a thermometer, wipe it with a dry cloth, you can bring it down to 35.
3. Place it in the armpit so that the tip filled with mercury is in close contact with the body.
4. Keep for at least 10 minutes.
5. You can evaluate the result.

How to correctly measure the temperature in the mouth:

• Before measuring the temperature in your mouth, you need to spend about five minutes at rest.
• If you have dentures in your mouth, remove them.
• If the thermometer is normal, wipe it dry and put it under the tongue on either side.
• Close your mouth, wait 4 minutes.

The normal temperature in a healthy person's mouth should be 37.3 degrees. It is worth noting that it is necessary to measure the temperature in the mouth with an ordinary thermometer with extreme caution.

What temperature is there?

Human temperature is divided into the following types:

Subfebrile temperature - 5 degrees. Such a temperature in a person may be normal and not cause danger, but it may also indicate pathological processes in the body. Therefore, it is very important to find out why a person's temperature has risen:

1. Overheating in the sun, strong physical activity.
2. Hot water treatments - sauna, steam bath.
3. Viral or colds.
4. Hot and spicy food.
5. Chronic ailments.

Serious diseases that threaten life also lead to a prolonged temperature of 37. Oncological diseases (a tumor can affect an organ such as the stomach) and tuberculosis in the early stages of development are characterized by a slight increase in temperature.

In some situations, such a body temperature is normal for a healthy person, and there is no need to bring it down. But, to make sure where the norm is, and where the deviations from it are, you need to consult a doctor.

Febrile temperature - 37.6, always signals that an inflammatory process is taking place in the body. The normal temperature rises to such a level as to fight off pathogenic microorganisms, creating unfavorable conditions for them. Therefore, you should not knock her down with medications.

You can simply drink more warm liquid to reduce the concentration of toxins and prevent dehydration.

A pyretic temperature - more than 39, indicates an acute course of the inflammatory process. If the mercury column shows such a value, doctors advise you to start taking antipyretic medications.

If a person's temperature is 39 degrees, convulsions are possible, so you need to be more attentive to people who have concomitant diseases.

The most common instigators of this temperature are microorganisms and viruses that enter the body. Also, such a body temperature is possible with severe burns, injuries.

Hyperthermia - temperature (40.3), makes you sound the alarm and immediately call an ambulance, it is important to know what to do if the temperature is 40 before the ambulance arrives. At 42 degrees, an organ such as the brain can be irreversibly damaged, the central nervous system is inhibited, and blood pressure drops.

If nothing is done, each internal organ is damaged, as a result of which a coma occurs, and the risk of death.

Low temperature

Which temperature is considered low and which is low? It's simple, there are situations when the mercury column shows less than 35 degrees, here you need to start worrying.

Indeed, at a temperature of 32, the patient will feel stunned, at 29.5, loss of consciousness occurs, and at 26.5, even a lethal outcome.

The reasons for the lowered temperature are:

• With hypothyroidism; due to alcoholic beverages (an organ such as the brain ceases to function, the center of thermoregulation is affected)
• Failure of the functioning of the central nervous system, brain damage (trauma, tumor).
• Paralysis, which causes weight loss and heat loss.
• Strict diets, constant hunger - all this leads to the fact that the body has little energy to generate heat, and every organ in the body "suffers".
• Hypothermia. Long-term presence of a person at a low temperature regime, as a result of which the body's own forces can no longer cope with the function of thermoregulation.
• Dehydration, as a result of which the body has little fluid, which leads to a decrease in metabolism.

A moderate decrease in the temperature regime (35.3) happens:

1. Normal fatigue, or serious physical activity, chronic lack of sleep.
2. Incorrect diet, or diet.
3. Hormonal disruption (pregnancy, thyroid disease, menopause).
4. Disrupted carbohydrate metabolism on the background of liver disease.

There are a number of methods you can use to raise your body temperature. As a rule, they do not imply any medication, except if the decrease is caused by serious illness.

To increase the temperature at home, you can put a heating pad with hot water under your feet, change into warmer clothes. Hot tea with honey, or decoctions with medicinal herbs (St. John's wort, ginseng) will help to increase.

In conclusion, it should be said that everyone has their own norm for body temperature. If one person feels great with a temperature of 37, and there are no inflammatory processes in the body, this does not mean that in a situation with another person it will be exactly the same.

It all depends on the individual characteristics of the organism, therefore, with the slightest doubt, it is necessary to visit a doctor. Elena Malysheva will popularly tell you what to do with the temperature in the video in that article.

Temperature

Temperature

Temperature changes are a frequent companion of diseases. Why, in most cases, it is not necessary to bring down the temperature and how to remove the fever, if necessary?

Human body temperature: norm, changes and symptom of diseases

What to do with fever is one of the most common questions for physicians and pediatricians. Indeed, fever often frightens patients. However, are increased values ​​always a reason for panic? Under what conditions does the temperature hold, and under what diseases does it, on the contrary, fall? And when is antipyretic really needed? What temperature should be normal in children and the elderly? MedAboutMe understood these and many other questions.

Body temperature in adults

Thermoregulation is responsible for human temperature - the ability of warm-blooded organisms to maintain a constant temperature, reduce or increase it if necessary. The hypothalamus is primarily responsible for these processes. However, today scientists are inclined to believe that it is wrong to define a single center of thermoregulation, because many factors affect a person's body temperature.

In childhood, the temperature changes under the slightest influence, while in adults (starting the rally) it is quite stable. Although, it also rarely keeps on one indicator all day. Physiological changes are known that reflect circadian rhythms. For example, the difference between normal temperature in the morning and in the evening in a healthy person will be 0.5-1.0 ° C. A characteristic increase in fever in the evening hours in a sick person is also associated with these rhythms.

The temperature can change under the influence of the external environment, increase with physical exertion, the intake of certain foods (especially often after spicy food and overeating), during stress, a feeling of fear, and even intense mental work.

What temperature should be normal

Everyone knows the value of 36.6 ° C. However, what temperature should actually be normal?

The figure 36.6 ° C appeared as a result of research carried out by the German physician Karl Reinhold Wunderlich in the middle of the 19th century. Then he made about 1 million temperature measurements in the armpit in 25 thousand patients. And 36.6 ° C was just the average of a healthy person's body temperature.

By modern standards, the norm is not a specific figure, but a range from 36 ° C to 37.4 ° C. Moreover, doctors recommend periodically measuring the temperature in a healthy state in order to accurately know the individual values ​​of the norm. It should be borne in mind that with age, the body temperature changes - in childhood it can be quite high, and decreases by old age. Therefore, an indicator of 36 ° C for an elderly person will be the norm, but for a child it can talk about hypothermia and a symptom of the disease.

It is also important to consider how the temperature is measured - the values ​​in the armpit, rectum or under the tongue can differ by 1-1.5 ° C.

Temperature during pregnancy

Fever is highly dependent on hormonal activity and it is therefore not surprising that pregnant women often experience fever. Hormonal changes are associated with hot flashes during menopause and temperature jumps during menstruation.

It is very important for expectant mothers to closely monitor their condition, while realizing that a slightly increased or decreased temperature during pregnancy is the norm for most women. For example, if the values ​​do not exceed 37 ° C in the first weeks, and there are no other symptoms of malaise, then the condition can be explained by the activity of female sex hormones. In particular, progesterone.

And yet, if the temperature during pregnancy lasts for a long time, then even subfebrile values ​​(37-38 ° C) should be a reason for consulting a doctor. With such a symptom, it is important to be examined and tested to exclude the presence of such infections - cytomegalovirus, tuberculosis, pyelonephritis, herpes, hepatitis and others.

Fever during pregnancy can also be a sign of common seasonal SARS. In this case, it is very important not to self-medicate, but to see a doctor. If a common cold is unlikely to pose a danger to the fetus, then the flu can lead to serious consequences, including early miscarriage. With flu, the temperature rises to 39 ° C.

Baby's temperature

The thermoregulation system in children under 1 year old has not yet been established, therefore, the temperature in a child can change significantly under the slightest influence. This is especially true for babies in the first three months of life. Most often, parents are worried about increased values, however, the reasons for a temperature of 37-38 ° C can be:

• Clothes that are too warm.
• Cry.
• Laughter.
• Food intake, including breastfeeding.
• Swimming in water above 34-36 ° C.

After sleep, the values ​​are usually lower, but with active games, the child's temperature rises quickly. Therefore, when making measurements, it is necessary to take into account all external factors that could affect them.

However, too high a temperature (38 ° C and above) can be dangerous for young children. The body uses a lot of water to compensate for the heat, and therefore dehydration is often observed. Moreover, in a child, this condition occurs faster than in an adult. Dehydration can pose a health hazard (often against its background there is a deterioration in the condition, subsequently ARVI is complicated by pneumonia) and life (with severe dehydration, there can be loss of consciousness and even death).

In addition, some children under 5 years old have febrile convulsions - when the child's temperature rises to 38-39 ° C, involuntary muscle contractions begin, and short-term fainting is possible. If at least once this condition was observed, in the future, even with a slight heat, the baby needs to bring down the temperature.

Human temperature

Normally, a person's temperature is controlled by the endocrine system, in particular, the hypothalamus and thyroid hormones (T3 and T4, as well as the hormone TSH, which regulates their production). Sex hormones affect thermoregulation. And yet, infections remain the main reason for the rise in temperature, and too low a temperature in most cases is caused by overwork or lack of vitamins, micro- and macroelements.

Degrees of temperature

Man is a warm-blooded creature, which means that the body can maintain a stable temperature regardless of environmental factors. At the same time, in severe frost, the total temperature decreases, and in case of heat it can rise so much that a person will receive heatstroke. This is due to the fact that our body is quite sensitive to thermal changes - changes of only 2-3 degrees in temperature significantly affect metabolic processes, hemodynamics and transmission of impulses through nerve cells. As a result, blood pressure may rise, seizures and confusion may occur. Frequent symptoms of low temperature are lethargy, at a value of 30-32 ° C there may be loss of consciousness; and high - delusional states.

Types of elevated temperature

For the vast majority of diseases that occur with an increase in temperature, certain ranges of values ​​are characteristic. Therefore, to make a diagnosis, it is often enough for a doctor to know not the exact value, namely the type of elevated temperature. In medicine, there are several types of them:

• Subfebrile - from 37 ° C to 38 ° C.
• Febrile - 38 ° C to 39 ° C.
• High - over 39 ° C.
• Life-threatening - 40.5-41 ° C.

Temperature values ​​are assessed in combination with other symptoms, since the degree of heat does not always correspond to the severity of the disease. For example, low-grade fever is observed in such dangerous diseases as tuberculosis, viral hepatitis, pyelonephritis and others. A particularly alarming symptom is a condition in which a temperature of 37-37.5 ° C is kept for a long time. This may indicate disruption of the endocrine system and even malignant tumors.

Fluctuations in normal body temperature

As already mentioned, the normal temperature in a healthy person can change throughout the day, as well as under the influence of certain factors (food, physical activity, etc.). In this case, you need to remember what temperature should be at different ages:

• Children under one year old - a temperature of 37-38 ° C can be considered the norm.
• Up to 5 years - 36.6-37.5 ° C.
• Adolescence - strong temperature fluctuations are possible associated with the activity of sex hormones. Values ​​are stabilized in girls in flight, in boys, drops can be observed up to 18 years of age.
• Adults - 36-37.4 ° C.
• Seniors over 65 - up to 36.3 ° C. A temperature of 37 ° C can be considered a serious febrile condition.

In men, the average body temperature is 0.5 ° C lower on average than in women.

How temperature is measured

There are several ways to measure body temperature. And in each case there will be their own norms of values. Among the most popular methods are:

In order to obtain accurate values, the skin must be dry, and the thermometer itself must be pressed tightly enough to the body. This method will take the most time (with a mercury thermometer - 7-10 minutes), since the skin must heat itself up. The norm of temperature degrees in the armpit is 36.2-36.9 ° C.

The method is most popular for young children, as one of the safest. For this method, it is better to use electronic thermometers with a soft tip, the measurement time is 1-1.5 minutes. The norm of values ​​is 36.8-37.6 ° C (on average, 1 ° C differs from the axillary values).

• Orally, sublingually (in the mouth, under the tongue).

Our method has not become widespread, although in European countries this is how the temperature is most often measured in adults. It takes from 1 to 5 minutes to measure, depending on the type of device. Temperature degrees are normal - 36.6-37.2 ° C.

The method is used to measure the temperature of a child and requires a special type of thermometer (non-contact measurement), therefore it is not widely used. In addition to determining the overall temperature, the method will also help in the diagnosis of otitis media. If there is inflammation, then the temperature in different ears will be very different.

It is most often used to determine the basal temperature (the lowest body temperature that is recorded during rest). Measured after sleep, an increase of 0.5 ° C indicates the onset of ovulation.

Types of thermometers

Today in pharmacies you can find different types of thermometers for measuring a person's temperature. Each of them has its own advantages and disadvantages:

It is considered one of the most accurate types and at the same time affordable. In addition, it is used in hospitals and clinics, since it is easily disinfected and can be used for a large number of people. Disadvantages include slow temperature measurement and fragility. A broken thermometer is dangerous because of the poisonous vapors of mercury. Therefore, today it is used quite rarely for children, it is not used for oral measurements.

The most popular type for home use. Quickly measures the temperature (from 30 seconds to 1.5 minutes), informs about the end with a sound signal. Electronic thermometers can be with soft tips (for rectal temperature measurement in a child) and rigid (universal devices). If the thermometer is used rectally or orally, it must be individual - for one person only. The disadvantage of such a thermometer is often inaccurate values. Therefore, after purchase, you need to measure the temperature in a healthy state in order to know the possible error range.

A relatively new and expensive type of thermometer. Used to measure temperature in a non-contact way, for example, in the ear, on the forehead or temple. The speed of obtaining the result is 2-5 seconds. A slight error of 0.2-0.5 ° C is allowed. A significant drawback of the thermometer is its limited use - it is not used for measurements in the usual ways (axillary, rectal, oral). In addition, each model is designed for its own way (forehead, temple, ear) and cannot be used in other areas.

Relatively recently, thermal strips have been popular - flexible films with crystals that change color at different temperatures. In order to get the result, it is enough to apply the strip to the forehead and wait about 1 minute. This method of measurement does not determine the exact degrees of temperature, but only shows the values ​​"low", "normal", "high". Therefore, it cannot replace full-fledged thermometers.

Fever symptoms

An increase in body temperature is well felt by a person. This condition is accompanied by the following symptoms:

• Fatigue, general weakness.
• Chills (the more the fever, the more the chills).
• Headache.
• Body aches, especially joints, muscles and fingers.
• Feeling cold.
• Sensation of heat in the eyeballs.
• Dry mouth.
• Decreased or complete loss of appetite.
• Rapid heartbeat, arrhythmias.
• Sweating (if the body can regulate the heat), dry skin (when the temperature rises).

Pink and white fever

Fever can manifest itself in different ways in children and adults. It is customary to distinguish two types of fever:

It was named so for its characteristic features - red skin, especially pronounced blush on the cheeks and face as a whole. The most common type of fever, in which the body is able to provide optimal heat transfer - the surface vessels expand (this is how the blood cools), sweating is activated (lowering the skin temperature). The patient's condition, as a rule, is stable, there are no significant violations of the general condition and well-being.

A rather dangerous form of fever, in which thermoregulatory processes fail in the body. The skin in this case is white, and sometimes even cool (especially cold hands and feet), while the measurement of rectal or oral temperature shows fever. A person suffers from chills, the condition worsens significantly, fainting and confusion may occur. White fever develops if there is a spasm of blood vessels under the skin, as a result of which the body cannot start cooling mechanisms. The condition is dangerous because the temperature rises significantly in vital organs (brain, heart, liver, kidneys, etc.) and can affect their functions.

Reasons for the rise in temperature

Thermoregulation is provided by the endocrine system, which triggers various mechanisms for increasing or decreasing a person's temperature. And of course, disturbances in the production of hormones or the functioning of the glands entail disturbances in thermoregulation. Such manifestations, as a rule, are stable, and the values ​​remain within the subfebrile range.

The main cause of elevated temperature is pyrogens, which can affect thermoregulation. Moreover, some of them are not introduced from the outside by pathogens, but are secreted by the cells of the immune system. Such pyrogens are designed to increase the effectiveness of the fight against various health-threatening conditions. The temperature rises in such cases:

• Infections - viruses, bacteria, protozoa and others.
• Burns, injuries. As a rule, there is a local increase in temperature, but with a large area of ​​\ u200b \ u200bthe lesion, there may be a general fever.
• Allergic reactions. In these cases, the immune system produces pyrogens to fight off harmless substances.
• Shock states.

ARI and high fever

Seasonal respiratory illness is the most common cause of fever. Moreover, depending on the type of infection, its values ​​will be different.

• With a standard cold or a mild form of acute respiratory viral infections, a subfebrile temperature is observed, in addition, it rises gradually, on average in 6-12 hours. With proper treatment, the fever lasts no more than 4 days, after which it begins to subside or disappears altogether.
• If the temperature rises sharply and exceeds 38 ° C, this may be a symptom of the flu. Unlike other acute respiratory viral infections, this disease requires the mandatory supervision of a local therapist or pediatrician.
• If the fever resumed after improvement in the condition or does not go away on the 5th day from the onset of the disease, this most often indicates complications. The initial viral infection was joined by a bacterial infection, the temperature being, as a rule, above 38 ° C. The condition requires an urgent call to the doctor, as the patient may need antibiotic therapy.

Diseases with a temperature of 37-38 ° C

A temperature of 37-38 ° C is typical for such diseases:

• ARVI.
• Exacerbations of chronic respiratory diseases. For example, bronchitis or bronchial asthma, tonsillitis.
• Tuberculosis.
• Chronic diseases of internal organs during an exacerbation: myocarditis, endocarditis (inflammation of the heart membranes), pyelonephritis and glomerulonephritis (inflammation of the kidneys).
• Ulcer, colitis.
• Viral hepatitis (usually hepatitis B and C).
• Herpes in the acute stage.
• Exacerbation of psoriasis.
• Infection with toxoplasmosis.

This temperature is typical for the initial stage of thyroid dysfunction, with increased production of hormones (thyrotoxicosis). Hormonal disturbances during menopause can also cause mild fever. Subfebrile values ​​can be observed in people with helminthic invasion.

Diseases with a temperature of 39 ° C and above

High temperature accompanies diseases that cause severe intoxication of the body. Most often, values ​​within 39 ° C degrees indicate the development of an acute bacterial infection:

• Angina.
• Pneumonia.
• Acute pyelonephritis.
• Diseases of the gastrointestinal tract: salmonellosis, dysentery, cholera.
• Sepsis.

At the same time, intense fever is typical for other infections:

• Flu.
• Hemorrhagic fever in which the kidneys are severely affected.
• Chicken pox.
• Measles.
• Meningitis, encephalitis.
• Viral hepatitis A.

Other causes of high fever

Thermoregulation disorders can be observed without visible diseases. Another dangerous reason that the temperature has risen is the inability of the body to provide adequate heat transfer. This happens, as a rule, with prolonged exposure to the sun during the hot season or in a too stuffy room. A child's temperature may rise if he is dressed too warmly. The condition is dangerous with heatstroke, which can be fatal for people with heart and lung disease. With severe overheating, even in healthy people, organs, primarily the brain, suffer significantly. Also, fever for no apparent reason can manifest itself in emotional people during periods of stress and intense excitement.

Low temperature symptoms

A low temperature is less common than a heat, but at the same time, it can also indicate serious health problems. Indicators of diseases and disorders of the body are considered indicators below 35.5 ° C for an adult, in older people - below 35 ° C.

The following degrees of body temperature are considered life-threatening:

• 32.2 ° C - a person will fall into a stupor, severe lethargy is observed.
• 30-29 ° C - loss of consciousness.
• Below 26.5 ° C - death is possible.

Low temperature is characterized by the following symptoms:

• General weakness, malaise.
• Drowsiness.
• Irritability may occur.
• The limbs get cold, numbness of the fingers develops.
• Disturbances of attention and problems with thought processes are noticeable, the speed of reactions decreases.
• General feeling of coldness, trembling in the body.

Low temperature reasons

Among the main reasons for the low temperature are the following:

• General weakness of the body caused by external factors and living conditions.

Inadequate nutrition, lack of sleep, stress and emotional distress can affect thermoregulation.

Associated, as a rule, with insufficient synthesis of hormones.

The most common cause of low fever in humans. The condition is dangerous by a violation of metabolic processes and frostbite of the extremities only in case of a strong drop in temperature. With a slight hypothermia, a person's local immunity decreases, so this or that infection often subsequently develops.

It is observed during the recovery period, after operations, and can manifest itself against the background of chemotherapy and radiation therapy. Also, low temperatures are typical for people with AIDS.

Endocrine system diseases

In the processes of thermoregulation, hormones play an important role. In particular, the thyroid hormones of the thyroid gland are thyroxine and triiodothyronine. With their increased synthesis, fever is often observed, but hypothyroidism, on the contrary, leads to a decrease in the overall temperature. In the initial stages, this is often the only symptom by which the development of the disease can be suspected.

A stable decrease in body temperature is also observed with adrenal insufficiency (Addison's disease). Pathology develops slowly, it may not manifest itself with other signs for months or even several years.

Low hemoglobin in the blood

Iron deficiency anemia is considered one of the most common causes of low fever. It is characterized by a decrease in hemoglobin in the blood, and this in turn affects the functioning of the whole organism. Hemoglobin is responsible for the transport of oxygen to cells, and if it is not enough, different degrees of hypoxia are manifested.

A person becomes lethargic, general weakness is noted, against the background of which metabolic processes slow down. Low temperatures are the result of these changes.

In addition, the hemoglobin level can also drop with various blood loss. In particular, people with internal bleeding can develop anemia. If significant blood loss occurs in a short period of time, the volume of circulating blood decreases, and this already affects heat exchange.

Other causes of low temperature

Among the dangerous conditions that require mandatory consultation with a doctor and treatment, one can single out the following diseases with a low temperature:

• Radiation sickness.
• Strong intoxication.
• AIDS.
• Diseases of the brain, including tumors.
• Shock of any etiology (with massive blood loss, allergic reactions, traumatic and toxic shock).

However, the most common causes of temperatures below 35.5 ° C are improper lifestyle and lack of vitamins. So, nutrition remains an important factor, if it is not enough, then the processes in the body will slow down, and as a result, thermoregulation will be disrupted. Therefore, with various strict diets, especially those with a poor diet (deficiency of iodine, vitamin C, iron), a low temperature without other symptoms is very common. If a person consumes less than 1200 calories per day, this will certainly affect thermoregulation.

Another common reason for this temperature is overwork, stress, lack of sleep. It is especially characteristic of chronic fatigue syndrome. The body goes into a sparing mode of functioning, metabolic processes slow down in the body and, of course, this is reflected in heat exchange.

Fever and other symptoms

Since temperature is only a symptom of various disorders in the body, it is best to consider it in conjunction with other signs of disease. It is the general picture of a person's condition that can tell what kind of disease is developing and how dangerous it is.

An increase in temperature is often observed with various ailments. However, there are characteristic combinations of symptoms that appear in patients with specific diagnoses.

Fever and pain

In the event that, with abdominal pain, the temperature is kept above 37.5 ° C, this may indicate serious violations of the gastrointestinal tract. In particular, this is observed with intestinal obstruction. In addition, a combination of symptoms is characteristic of the development of appendicitis. Therefore, if the pain is localized in the right hypochondrium, it is difficult for a person to pull his legs to the chest, there is a loss of appetite and cold sweat, an ambulance should be called immediately. Complication of appendicitis, peritonitis, is also accompanied by persistent fever.

Other causes of a combination of abdominal pain and fever:

• Pyelonephritis.
• Acute pancreatitis.
• Bacterial bowel disease.

If the temperature rises against the background of pain in the head, this most often indicates a general intoxication of the body and is observed with such diseases:

Joint and muscle pains, discomfort in the eyeballs are symptoms of temperatures above 39 ° C. In such conditions, it is recommended to take an antipyretic.

Fever and diarrhea

An increased temperature against the background of diarrhea is a clear sign of bacterial infection of the gastrointestinal tract. Among intestinal infections with the following symptoms:

The cause of the temperature against the background of diarrhea can also be severe food poisoning. The combination of such symptoms is very dangerous to health, therefore, self-medication in such cases is unacceptable. It is necessary to urgently call an ambulance and, if necessary, agree to hospitalization. This is especially true if the child is sick.

Fever and diarrhea are contributing factors to dehydration. And with their combination, the loss of fluid by the body can become critical in a fairly short period. Therefore, in the event that it is not possible to adequately compensate for the lack of fluid with drinking (for example, a person has vomiting or the diarrhea itself is pronounced), the patient is injected with solutions intravenously in a hospital. Without it, dehydration can lead to serious consequences, organ damage and even death.

Fever and nausea

In some cases, nausea can be caused by fever. Due to intense heat, weakness develops, blood pressure decreases, dizziness occurs, and this is what causes mild nausea as a result. In this condition, if the temperature is above 39 ° C, it must be brought down. A combination of symptoms can appear in the early days of the flu and be caused by severe intoxication of the body.

One of the causes of nausea and fever during pregnancy is toxicosis. But in this case, values ​​above subfebrile (up to 38 ° C) are rarely observed.

In the event that nausea is accompanied by other disorders of the gastrointestinal tract (for example, pain, diarrhea, or, conversely, constipation), simply bringing down the temperature is not enough. This combination of symptoms can indicate serious diseases of the internal organs. Among them:

• Viral hepatitis and other liver damage.
• Acute appendicitis.
• Peritonitis.
• Inflammation of the kidneys.
• Acute pancreatitis.
• Bowel obstruction (accompanied by constipation).

In addition, fever and nausea are often observed against the background of intoxication with stale food, alcohol or drugs. And one of the most dangerous diagnoses for these symptoms is meningitis. All of the listed diseases and conditions require mandatory consultation with a doctor.

In the event that vomiting occurs against the background of the temperature, it is very important to compensate for the loss of fluid. Children with this combination of symptoms are most often referred for inpatient treatment.

Pressure and temperature

Increased blood pressure is a common symptom of fever. Fever affects hemodynamics - the heart rate increases in patients, and the blood begins to move faster through the vessels, they expand, and this can affect blood pressure. However, such changes cannot cause severe hypertension, more often the indicators do not exceed 140/90 mm Hg. Art., observed in patients with a fever of 38.5 ° C and above, disappear as soon as the temperature stabilizes.

In some cases, high temperatures, on the contrary, are characterized by a decrease in pressure. There is no need to treat this condition as the readings return to normal after the fever subsides.

At the same time, for hypertensive patients, any, even a slight fever, can threaten with serious consequences. Therefore, they should consult with their attending physician and, if necessary, take antipyretics already at rates from 37.5 ° C (especially when it comes to the elderly).

Pressure and temperature are a dangerous combination for patients with such diseases:

• Cardiac ischemia. Cardiologists note that this combination of symptoms sometimes accompanies myocardial infarction. Moreover, in this case, the temperature rises slightly, it may be within the framework of subfebrile indicators.
• Heart failure.
• Arrhythmias.
• Atherosclerosis.
• Diabetes.

In the event that low pressure and temperature in the subfebrile range persist for a long time, this may be a sign of oncopathology. However, not all oncologists agree with this statement, and the symptoms themselves should simply become a reason for a full examination of a person.

Low pressure and low temperature are common combinations. Such symptoms are especially characteristic with low hemoglobin, chronic fatigue, blood loss, and nervous disorders.

Fever without other symptoms

An elevated or lowered temperature without symptoms characteristic of acute infections should be the reason for a mandatory medical examination. Violations can talk about such diseases:

• Chronic pyelonephritis.
• Tuberculosis.
• Malignant and benign tumors.
• Organ infarctions (tissue necrosis).
• Diseases of the blood.
• Thyrotoxicosis, hypothyroidism.
• Allergic reactions.
• Early stage rheumatoid arthritis.
• Disorders of the brain, in particular, the hypothalamus.
• Mental disorders.

Fever without other symptoms also occurs against the background of overwork, stress, after prolonged physical activity, overheating or hypothermia. But in these cases, the indicators stabilize. If we are talking about serious diseases, the temperature without symptoms will be quite stable, after normalization, it will rise or fall again over time. Sometimes hypothermia or hyperemia is observed in a patient for several months.

How to lower the temperature

An elevated temperature can cause significant discomfort, and in some cases even pose a threat to life. Therefore, any person needs to know what to do with a fever and how to bring down the temperature correctly.

When to bring down the temperature

Not always, if the temperature rises, it needs to be brought back to normal. The fact is that with infections and other lesions of the body, he himself begins to produce pyrogens, which cause fever. The high temperature helps the immune system fight off antigens, in particular:

• The synthesis of interferon, a protein that protects cells from viruses, is activated.
• The production of antibodies is activated, which destroy antigens.
• The process of phagocytosis is accelerated - the absorption of foreign bodies by phagocytic cells.
• Reduced physical activity and appetite, which means that the body can spend more energy to fight infection.
• Most bacteria and viruses survive best at normal human temperatures. When it rises, some microorganisms die.

Therefore, before deciding to "bring down the temperature", you need to remember that fever helps the body to recover. However, there are still situations in which the heat must be removed. Among them:

• The temperature is over 39 ° C.
• Any temperature at which there is a serious deterioration in the condition - nausea, dizziness, etc.
• Febrile convulsions in children (any fever above 37 ° C goes astray).
• In the presence of concomitant neurological diagnoses.
• People with diseases of the heart and blood vessels, with diabetes mellitus.

Air, humidity and other parameters in the room

There are many ways to lower the temperature. But the first task should always be to normalize the air parameters in the room where the patient is. This is especially important for children in the first years of life, and it is critical for babies. The fact is that the child's perspiration system is still poorly developed and therefore thermoregulation is carried out to a greater extent through breathing. The baby inhales cool air, which cools his lungs and the blood in them, and exhales warm air. In the event that the room is too warm, this process is ineffective.

Indoor humidity is also important. The fact is that the humidity of the exhaled air is normally close to 100%. At a temperature, breathing quickens and if the room is too dry, through breathing a person additionally loses water. In addition, the mucous membranes dry out, congestion develops in the bronchi and lungs.

Therefore, the ideal parameters in the room where the patient with fever is located are as follows:

Antipyretic drugs

In the event that you need to quickly bring down the temperature, you can use antipyretics. They are taken symptomatically, which means that as soon as the symptom goes away or becomes less pronounced, the medication is stopped. Drinking antipyretics throughout the disease for prevention is unacceptable.

One of the main conditions for the successful action of this group of drugs is drinking plenty of fluids.

Actively prescribed for adults and children, it is considered a first-line drug. However, recent studies, in particular, carried out by the American organization FDA, have shown that with uncontrolled intake of the drug, paracetamol can cause serious liver damage. Paracetamol works well if the temperature does not exceed 38 ° C, but in extreme heat it may not work.

One of the key non-steroidal anti-inflammatory drugs (NSAIDs) used for fever. It is prescribed for adults and children.

For a long time it was the main drug in the NSAID category, but over the past decades it has been proven to be associated with severe kidney and liver damage (in case of overdose). Researchers also believe that taking aspirin in children can cause the development of Reye's syndrome (pathogenic encephalopathy), so at the moment the drug is not used in pediatrics.

Latest generation non-steroidal anti-inflammatory agent. Contraindicated in children.

Today it is practically not used as an antipyretic, but it can still relieve fever.

Folk remedies

The temperature can also be brought down with the help of folk remedies. Among the most common and simple methods are decoctions of herbs and berries. Drinking plenty of fluids is always recommended at high temperatures, as it helps improve sweating and reduces the risk of dehydration.

Some of the more popular herbs and berries that are used for fever are:

A hypertonic solution will also help to normalize the temperature. It is prepared from ordinary boiled water and salt - two teaspoons of salt are taken for 1 glass of liquid. This drink helps the cells retain water and is great if the temperature is manifested against the background of vomiting and diarrhea.

• Newborns - no more than 30 ml.
• From 6 months to 1 year - 100 ml.
• Up to 3 years - 200 ml.
• Up to 5 years - 300 ml.
• Over 6 years old - 0.5 liters.

Ice can also be used for fever symptoms. But you need to use it very carefully, since a sharp cooling of the skin can lead to vasospasm and the development of white fever. Ice is placed in a bag or placed on a piece of cloth and only in this form is applied to the body. Drying off with a towel dipped in cold water is a good alternative. In the event that it is not possible to bring down the temperature, antipyretics do not work, and folk remedies do not help, you need to urgently call an ambulance.

How to raise the temperature

If the body temperature drops below 35.5 ° C, the person feels weak and unwell, you can increase it in the following ways:

• Warm, abundant drink. Tea with honey, rosehip broth helps well.
• Liquid warm soups and broths.
• Warm clothes.
• Covering with several blankets, a heating pad can be used for greater effect.
• Hot bath. May be supplemented with essential oils of coniferous trees (fir, spruce, pine).
• Exercise stress. A few vigorous exercise will help improve circulation and body temperature.

In the event that the temperature is kept below 36 ° C for a long time, you need to consult a doctor. And after finding out the cause of such a symptom, the specialist will prescribe the appropriate treatment.

When urgent medical attention is needed

In some cases, high fever can pose a serious threat to health, and then you simply cannot do without the help of doctors. An ambulance must be called in such cases:

• Temperature 39.5 ° C and above.
• A sharp increase in temperature and the inability to bring it down with antipyretic and other methods.
• Against the background of the temperature, diarrhea or vomiting is observed.
• The fever is accompanied by shortness of breath.
• There are severe pains in any part of the body.
• There are signs of dehydration: dry mucous membranes, pallor, severe weakness, dark urine or lack of urination.
• High pressure and temperature above 38 ° C.
• The fever is accompanied by a rash. A red rash that does not disappear with pressure is especially dangerous - a sign of meningococcal infection.

Fever or a drop in temperature is an important signal from the body about illness. This symptom should always be given due attention and try to fully understand its causes, and not just eliminate it with the help of drugs and other methods. But at the same time, do not forget that normal temperature is an individual concept and not everyone corresponds to the well-known indicator of 36.6 ° C.
