What causes low body temperature. Low body temperature causes in an adult

“Normal” body temperature is considered to be a temperature of 36.6 ° C, however, in fact, each person has his own individual temperature norm in the average range from 35.9 to 37.2 ° C. This personal temperature is formed by about 14 years for girls and 20 for guys, and it depends on age, race, and even ... gender! Yes, men are on average half a degree "colder" than women. By the way, during the day the temperature of every absolutely healthy person makes a slight fluctuation within half a degree: in the morning the human body is colder than in the evening.

When to run to the doctor?

Deviations in body temperature from the norm, both upward and downward, are often a reason to consult a doctor.

Very low temperature - 34.9 to 35.2 °C - talking about:

As you can see from this list, any of the reasons described suggests an urgent visit to the doctor. Even a hangover, if it is so severe, should be treated with a course of droppers that will help the body get rid of the toxic breakdown products of alcohol faster. By the way, thermometer readings below the specified limit is already a direct reason for an urgent call for an ambulance.

Moderate drop in temperature – 35.3 to 35.8 °C – may refer to:

In general, a constant feeling of chilliness, cold and damp palms and feet is a reason to see a doctor. It is quite possible that he will not find any serious problems with you, and will only recommend “improving” nutrition and making the daily routine more rational, including moderate physical activity and increasing the duration of sleep. On the other hand, it is likely that the unpleasant chill that torments you is one of the first symptoms of a formidable disease that needs to be treated right now, before it has time to develop complications and go into the chronic stage.

Normal temperature - from 35.9 to 36.9°C - says that acute illnesses at the moment you are not suffering, and your thermoregulation processes are normal. However, not always normal temperature is combined with the ideal order in the body. In some cases, with chronic diseases or reduced immunity, temperature changes may not occur, and this must be remembered!

Moderately elevated (subfebrile) temperature - from 37.0 to 37.3°C – it is the boundary between health and disease. May refer to:

However, such a temperature may also have absolutely “painful” reasons:

bath or sauna visit, hot bath
intense sports training
spicy food

In the case when you didn’t exercise, didn’t go to the bathhouse, and didn’t have dinner at a Mexican restaurant, and the temperature is still a little elevated - you should go to the doctor, and it’s very important to do this without taking any antipyretic and anti-inflammatory drugs - firstly , at this temperature they are not necessary, and secondly, medical preparations can blur the picture of the disease and prevent the doctor from making a correct diagnosis.

Heat – 37.4-40.2°C – indicates acute inflammatory process and the need medical care. The question of whether to take antipyretic drugs in this case is decided individually. It is widely believed that temperatures up to 38 ° C cannot be “knocked down” - and in most cases this opinion is true: the proteins of the immune system begin to work in full force precisely at temperatures above 37.5 ° C, and the average person without severe chronic diseases able to endure temperatures up to 38.5 ° C without additional harm to health. However, people suffering from certain neurological and mental illnesses should be careful: they can cause a high temperature.

Temperatures above 40.3°C are life threatening and require emergency medical attention.

Several interesting facts about temperature:

There are foods that reduce body temperature by almost a degree. These are green varieties of gooseberries, yellow plums and cane sugar.
In 1995, scientists officially recorded the lowest "normal" body temperature - in a completely healthy and perfectly feeling 19-year-old Canadian, it was 34.4 ° C.
Known for their extraordinary therapeutic findings, Korean doctors have come up with a way to treat the seasonal autumn-spring that many people suffer from. They suggested lowering the temperature of the upper body while raising the temperature of the lower half. In fact, this is a well-known health formula “Keep your feet warm and your head cold”, but doctors from Korea say that it is also applicable to improve a mood stubbornly striving for zero.

We measure correctly!

However, instead of panicking about abnormal body temperature, you should first think about whether you are measuring it correctly? A mercury thermometer under the arm, familiar to everyone since childhood, does not give the most accurate results.

Firstly, it is still better to purchase a modern, electronic thermometer, which allows you to measure the temperature with an accuracy of hundredths of a degree.

Secondly, the place of measurement is important for the accuracy of the result. The armpit is convenient, but due to a large number sweat glands - inaccurate. The oral cavity is also convenient (just remember to disinfect the thermometer), but you must remember that the temperature there is approximately half a degree higher than the temperature in the armpit, in addition, if you ate or drank something hot, smoked or have consumed alcohol, readings may be falsely high.

Measuring the temperature in the rectum gives one of the most accurate results, it should only be taken into account that the temperature there is about a degree higher than the temperature under the arm, in addition, the thermometer readings may be false after sports training or taking a bath.

And, the “champion” in terms of the accuracy of the result is the external auditory canal. It is only necessary to remember that measuring the temperature in it requires a special thermometer and precise observance of the nuances of the procedure, the violation of which can lead to erroneous results.

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 heat, if necessary?

What to do with elevated body temperature is one of the most common questions for therapists and pediatricians. Indeed, the heat often frightens patients. However, are elevated values always a cause for panic? Under what conditions does the temperature stay, and under what diseases does it, on the contrary, fall? And when are antipyretics really needed? What temperature should be normal in children and the elderly? MedAboutMe dealt with these and many other issues.

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 determine a single center of thermoregulation, because many factors affect the temperature of the human body.

In childhood, the temperature changes under the slightest influence, while in adults (from 16-18 years old) it is quite stable. Although it also rarely stays 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. With these rhythms, a characteristic increase in fever in the evening hours in a sick person is also associated.

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

What temperature should be normal

Everyone is well aware of the value of 36.6 ° C. However, what temperature should be normal in reality?

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

According to 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 healthy condition to accurately know the individual values of the norm. It should be borne in mind that with age, body temperature changes - in childhood it can be quite high, and in old age it drops. Therefore, an indicator of 36 ° C for an elderly person will be the norm, but for a child it can indicate 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.

The temperature is very dependent on hormonal activity and therefore it is not surprising that pregnant women often experience fever. FROM hormonal changes hot flashes during menopause and temperature fluctuations during menstruation are associated.

It is very important for expectant mothers to carefully monitor their condition, while understanding that a slightly elevated or low 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. Particularly progesterone.

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

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

The child's temperature

The system of thermoregulation in children under 1 year of age 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 concerned about elevated values, however, the causes of a temperature of 37-38 ° C can be:

Too warm clothes.
Cry.
Laugh.
Eating, including breastfeeding.
Bathing in water above 34-36°C.

After sleep, the values \u200b\u200bare usually lower, but with active games, the child's temperature rises quickly. Therefore, when taking measurements, it is necessary to take into account all external factors that could affect them.

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

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

Human temperature

Normally, human temperature is controlled by the endocrine system, in particular, the hypothalamus and hormones. thyroid gland(T3 and T4, as well as hormone TSH that regulates their production). Thermoregulation is influenced by sex hormones. But still main reason temperature rises remain infections, and too low a temperature in most cases is caused by overwork or a lack of vitamins, micro- and macroelements.

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 overall temperature drops, and in hot weather it can rise so much that a person will get heat stroke. 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 the transmission of impulses along nerve cells. As a result, pressure may increase, convulsions 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 fever

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

Subfebrile - from 37 ° C to 38 ° C.
Febrile - from 38°C to 39°C.
High - more than 39°C.
Dangerous for life - the line is 40.5-41 ° C.

Temperature values are evaluated in combination with other symptoms, since the degree of fever does not always correspond to the severity of the disease. For example, subfebrile temperature observed with such dangerous diseases like tuberculosis, viral hepatitis, pyelonephritis and others. A particularly alarming symptom is a condition in which the temperature is kept at 37-37.5 ° C for a long time. This may indicate a malfunction. 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, and more). 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 fluctuations in temperature are possible, associated with the activity of sex hormones. The values stabilize in girls at the age of 13-14, in boys differences can be observed up to 18 years.
Adults - 36-37.4 ° C.
Elderly people over 65 years old - up to 36.3 ° C. A temperature of 37°C can be considered a serious febrile condition.

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

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:

Axillary (in the armpit).

In order to get 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 mercury thermometer– 7-10 minutes), because the skin should warm up on its own. The norm of temperature degrees in the armpit is 36.2-36.9 ° C.

Rectally (in the rectum).

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, it differs by 1 ° C from axillary values).

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

In our country, the method is not widely used, although in Europe this is how the temperature in adults is most often measured. It takes from 1 to 5 minutes to measure, depending on the type of device. The temperature values are normal - 36.6-37.2 ° C.

In the ear canal.

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 very common. In addition to determining the overall temperature, the method will also help in the diagnosis of otitis media. If there is inflammation, then in different ears the temperature will be very different.

Into the vagina.

It is most often used to determine 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 thermometers to measure human temperature. Each of them has its own advantages and disadvantages:

Mercury (maximum) thermometer.

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

Electronic (digital) thermometer.

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 hard (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.

Infrared thermometer.

Relatively new and expensive. Used to measure temperature in a non-contact way, for example, in the ear, 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 disadvantage 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 method (forehead, temple, ear) and cannot be used in other areas.

Relatively recently, thermal strips were 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 for about 1 minute. This method of measurement does not determine the exact degrees of temperature, but only shows the values \u200b\u200bof "low", "normal", "high". Therefore, it cannot replace full-fledged thermometers.

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 fever, the more chills).
Headache.
Aches in the body, especially in the joints, muscles and fingers.
Feeling cold.
Sensation of heat in the region of the eyeballs.
Dry mouth.
Decrease or total loss appetite.
Rapid heartbeat, arrhythmias.
Sweating (if the body can regulate heat), dry skin (when the temperature rises).

Rose and white fever

High fever can manifest differently in children and adults. It is customary to distinguish two types of fever:

Pink (red).

So named after characteristics- 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 superficial vessels expand (this is how the blood cools), sweating is activated (decrease in skin temperature). The patient's condition is usually stable, there are no significant disorders general condition and well-being.

White.

A rather dangerous form of fever, in which failures of thermoregulatory processes occur 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 is tormented by chills, the condition worsens significantly, fainting and confusion can be observed. white fever develops if there is a spasm of blood vessels under the skin, as a result of which the body cannot start the cooling mechanisms. The condition is dangerous in that the temperature rises significantly in vital organs (brain, heart, liver, kidneys, etc.) and can affect their functions.

Thermoregulation is provided by the endocrine system, which triggers various mechanisms to increase or decrease a person's temperature. And of course, violations in the production of hormones or the functioning of the glands lead to violations of thermoregulation. Such manifestations, as a rule, are stable, and the values remain within the subfebrile range.

The main cause of elevated temperature are pyrogens, which can affect thermoregulation. Moreover, some of them are not introduced from the outside by pathogens, but are secreted by 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 the lesion there may be a general fever.
Allergic reactions. In these cases, the immune system produces pyrogens to fight harmless substances.
shock states.

ARI and high fever

Seasonal respiratory diseases- the most common cause temperature increase. In this case, depending on the type of infection, its values will be different.

For the common cold or mild form ARVI is observed subfebrile temperature, in addition, it rises gradually, on average in 6-12 hours. At proper treatment the fever lasts no more than 4 days, after which it begins to subside or disappear 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 mandatory monitoring by a local therapist or pediatrician.
If the fever resumed after the condition improved or did not go away on the 5th day from the onset of the disease, this most often indicates complications. To the initial viral infection bacterial has joined, the temperature is usually above 38 ° C. The condition requires an urgent call to the doctor, as the patient may need antibiotic therapy.

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

SARS.
Exacerbations of chronic diseases respiratory tract. For example, bronchitis or bronchial asthma, tonsillitis.
Tuberculosis.
chronic diseases 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.
Gastrointestinal diseases: salmonellosis, dysentery, cholera.
Sepsis.

At the same time, intense fever is also characteristic of 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

Violations of thermoregulation can be observed without visible diseases. Another one dangerous reason the fact that the temperature has risen - the inability of the body to provide adequate heat transfer. This happens, as a rule, with prolonged exposure to the sun in the hot season or in a too stuffy room. The temperature of the child 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. In case of severe overheating, even healthy people Organs, especially the brain, are severely affected. Also fever without visible reasons may appear in emotional people during periods of stress and intense excitement.

Low temperature fever is less common, but it can also indicate serious health problems. Indicators below 35.5 ° C for an adult are considered a sign of diseases and disorders of the body, and below 35 ° C in the elderly.

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

32.2 ° C - a person will fall into a stupor, there is a strong lethargy.
30-29°C - loss of consciousness.
Below 26.5 ° C - a fatal outcome is possible.

Low temperature is characterized by the following symptoms:

General weakness, malaise.
Drowsiness.
There may be irritability.
The extremities become cold, numbness of the fingers develops.
Attention disturbances and problems with thought processes are noticeable, the speed of reactions decreases.
General feeling of coldness, trembling in the body.

Causes of low temperature

Among the main reasons for low temperatures are the following:

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

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

Endocrine system disorders.

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

Hypothermia.

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

Weakened immune system.

It is observed during the recovery period, after operations, may occur against the background of chemotherapy and radiotherapy. Also low temperature is typical for people with AIDS.

Hormones play an important role in the processes of thermoregulation. In particular, the thyroid hormones of the thyroid gland are thyroxine and triiodothyronine. With their increased synthesis, heat is often observed, but, on the contrary, it 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, may not show other signs for months or even several years.

Low hemoglobin in the blood

One of the most common causes of low temperatures is Iron-deficiency anemia. 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 the cells, and if it is not enough, different degrees of hypoxia appear.

The person becomes lethargic, there is a general weakness, against which metabolic processes slow down. The low temperature is the result of these changes.

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

Other causes of low temperature

Among the dangerous conditions that require mandatory medical advice and treatment, one can single out such diseases with a low temperature:

Radiation sickness.
Severe intoxication.
AIDS.
Brain diseases, 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 an unhealthy lifestyle and a 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 disturbed. Therefore, with various strict diets, especially with a poor diet (deficiency of iodine, vitamin C, iron), low temperature without other symptoms is very common. If a person consumes less than 1200 calories per day, this will definitely affect thermoregulation.

Another common cause of such a 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 affects heat transfer.

Since temperature is only a symptom of various disorders in the body, it is best to consider it in combination with other signs of illness. It is the general picture of a person’s condition that can tell what kind of disease develops 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.

Temperature and pain

In the event that, with pain in the abdomen, the temperature is 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 region of the right hypochondrium, it is difficult for a person to pull his legs to his chest, there is a loss of appetite and cold sweat, an ambulance should be called immediately. A complication of appendicitis, peritonitis, is also accompanied by persistent fever.

Other causes of a combination of abdominal pain and temperature:

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 in such diseases:

Influenza and other SARS.
Angina, scarlet fever.
Encephalitis.
Meningitis.

Pain in joints and muscles, discomfort in eyeballs are symptoms of a temperature above 39°C. In such conditions, it is recommended to take an antipyretic.

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

Salmonellosis.
Cholera.
Botulism.
Dysentery.

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

Temperature and diarrhea are factors that contribute to dehydration. And with their combination, fluid loss 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 by 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, damage to organs and even death.

Temperature and nausea

In some cases, nausea may be due to fever. Due to intense heat, weakness develops, pressure decreases, dizziness occurs, and this is what causes slight nausea as a result. In this state, if the temperature is above 39 ° C, it must be brought down. The combination of symptoms may appear in the first 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 higher than 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 may indicate serious illnesses internal organs. Among them:

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

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

In the event that vomiting occurs against the background of 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.

An increase in blood pressure - common symptom temperature. Heat affects hemodynamics - patients have an increased heart rate, and 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 rates 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, a high temperature, on the contrary, is characterized by a decrease in pressure. There is no need to treat this condition, as the indicators 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 doctor and, if necessary, take antipyretics already at rates of 37.5 ° C (especially when it comes to older people).

Pressure and temperature is 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, 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 last 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 the reason for a full-fledged examination of a person.

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

Temperature without other symptoms

Elevated or decreased temperature without symptoms characteristic of acute infections, should be the reason for the mandatory medical examination. Violations can talk about such diseases:

Chronic pyelonephritis.
Tuberculosis.
Malignant and benign tumors.
Organ infarcts (tissue necrosis).
Blood diseases.
Thyrotoxicosis, hypothyroidism.
Allergic reactions.
Rheumatoid arthritis at an early stage.
Violations of the brain, in particular, the hypothalamus.
Mental disorders.

Temperature 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.

An elevated temperature can cause significant discomfort, and in some cases even be life-threatening. 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 has risen, 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. High temperature helps the immune system fight antigens, in particular:

The synthesis of interferon, a protein that protects cells from viruses, is activated.
The production of antibodies that destroy antigens is activated.
Accelerates the process of phagocytosis - absorption foreign bodies phagocyte cells.
Reduced physical activity and appetite, which means that the body can spend more energy to fight infection.
Most bacteria and viruses thrive best at normal human temperatures. With its increase, some microorganisms die.

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

Temperature above 39°C.
Any temperature at which there is a serious deterioration in the condition - nausea, dizziness, and so on.
Febrile convulsions in children (any fever above 37 ° C is knocked down).
In the presence of concomitant neurological diagnoses.
People with diseases of the heart and blood vessels, with diabetes.

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 located. This is especially important for children of the first years of life, and critical for infants. The fact is that the child's sweating 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 inefficient.

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

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

The air temperature is 19-22°C.
Humidity - 40-60%.

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 passes 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 drugs in this group is drinking plenty of water.

The main antipyretics:

Paracetamol.

It is actively prescribed for adults and children, it is considered a first-line drug. However, recent studies, in particular those conducted by the American organization FDA, have shown that if the drug is taken uncontrolled, paracetamol can cause serious liver damage. Paracetamol helps well if the temperature does not exceed 38 ° C, but in extreme heat it may not work.

Ibuprofen.

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

Aspirin (acetylsalicylic acid).

For a long time it was the main drug of the NSAID category, but over the past decades, its association with severe kidney and liver damage (with overdose) has been proven. Also, researchers 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.

Nimesulide (nimesil, nise).

Non-steroidal anti-inflammatory agent latest generation. Contraindicated in children.

Analgin.

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

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

Among the most popular herbs and berries that are used for fever are:

Raspberries, including leaves.
Black currant.
Sea buckthorn.
Cowberry.
Linden.
Chamomile.

To normalize the temperature, a hypertonic solution will also help. It is prepared from ordinary boiled water and salt - two teaspoons of salt are taken for 1 glass of liquid. Such a drink helps cells retain water and is great if the temperature manifests itself 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 l.

Ice can also be used for fever symptoms. But it must be used 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. A good alternative would be wiping with a towel dipped in cold water. In the event that it is not possible to bring down the temperature, antipyretics do not work, but folk remedies does not help, you need to urgently call an ambulance.

How to raise the temperature

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

Warm plentiful drink. Well helps tea with honey, rosehip broth.
Liquid warm soups and broths.
Warm clothes.
Covering with several blankets, for greater effect, you can use a heating pad.
Hot bath. Can be supplemented essential oils coniferous trees (fir, spruce, pine).
Exercise stress. A few intense exercises will help improve circulation and increase body temperature.

If the temperature stays below 36°C for a long time, you should consult a doctor. And after finding out the cause of such a symptom, the specialist will prescribe the appropriate treatment.

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

Temperature 39.5°C or higher.
A sharp increase in temperature and the inability to bring it down with antipyretic and other methods.
Against the background of temperature, diarrhea or vomiting is observed.
Fever is accompanied by difficulty breathing.
There is severe pain in any part of the body.
There are signs of dehydration: dry mucous membranes, pallor, severe weakness, dark urine or no urination.
High blood pressure and temperatures above 38°C.
The fever is accompanied by a rash. Especially dangerous is a red rash that does not disappear with pressure - a sign of a meningococcal infection.

Fever or a decrease in temperature is an important signal of the body about diseases. 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, one should not forget that normal temperature is an individual concept and not everyone corresponds to the well-known indicator of 36.6 ° C.

Temperature fluctuations, especially low values, signal problems in the body. The most common cause for concern is high fever. However, there are cases when the body temperature after the measurement is lowered.

According to scientists, normal body temperature ranges from 36.2-37.2°C. The most common option is -36.6°C. However, a considerable number of people all their lives (or in some period of it) have a temperature that differs from normal by 0.5 -1 ° C with absolutely normal health and good health indicators.

And for this there are many various reasons: from serious health problems to jet lag. The reason for the low body temperature may be a natural predisposition.

Low temperature is expressed in the following symptoms:

general depression;
weakness;
constant desire to sleep;
fast fatiguability;
pallor of the skin;
chills;
dizziness;
mood swings, with an emphasis on the negative side.

How to measure temperature correctly

It is important to measure the temperature regularly, over several days, at the same time.. It is advisable to use a familiar measuring device. During the control period, it is better not to allow a regime change. For example, under stress, the temperature often rises slightly, a hearty lunch before measurement can also blur the overall picture.

Any thermometer can be used. The thermometer, popular in the West, which measures the temperature of the mucous membrane, is especially convenient for children. When measuring temperature with this device, it is important to remember that in the oral cavity the temperature is even normal a little higher - at the classic 36.6 ° C, the thermometer will show 37 ° C during oral measurement.

During the day, fluctuations in body temperature are not uncommon. For most people, natural indicators early morning can serve 36°C, and at approximately 4 pm - 36.6°C.

Women in different periods menstrual cycle may have different body temperatures. For example, during ovulation, most women notice a slight increase in temperature, and before menstruation - a decrease. Prolonged hypothermia also affects the temperature.

The temperature is constantly low - this is a pathology

Low body temperature is not always a pathology. When complaining of low degrees, doctors conduct examinations and prescribe tests that reveal the presence of health problems. If none are found, and the numbers “36” are constantly observed on the thermometer, the temperature is recognized as a variant of the norm.

Often, low temperature is observed in premature babies and infants. This is due to an insufficiently formed system of thermoregulation and blood supply.

Pathology is a constantly lowered body temperature within 35 ° C. If a low (less than 35 ° C) temperature is observed for a long time, a diagnosis of "hypothermia" is made and large-scale examinations of the body are prescribed to identify the causes of the deviation, since the body is not able to function normally at such a temperature.

Attention! When the temperature drops to a value of 25 ° C, death most often occurs.

Causes of low body temperature

Often, fever is just one of the symptoms and may not even cause any particular inconvenience.

SARS

Below normal values appear on the thermometer with a cold. The reason for the low temperature in ARVI may be the general weakness of the body. The immune system- the most important fighter against infections and viruses, so its weakening can cause a new wave of the disease.

At the same time, during the struggle with infectious diseases the body spends a lot of nutrients and low temperature in this case is caused by a lack of vitamins and minerals.

Also, body temperature can drop during the period when the cold is almost defeated. This is observed against the background of taking drugs to reduce fever - the body independently fights the symptoms of the disease and an additional pharmacological agent acts.

The temperature will also drop when the patient, who has not yet fully recovered, decides to resort to significant physical exertion, such as sports training. This will cause rapid fatigue, and it will lower the temperature.

Low hemoglobin

Among the causes of low body temperature are low levels of hemoglobin, an iron-containing protein that helps circulatory system nourish the whole body. Insufficient production of hemoglobin leads to an anabiotic state against the background of a lack of oxygen, a decrease in the intensity of metabolism, which causes a decrease in temperature, especially if the shortage is constant.

In this case, the body "falls asleep", reducing the activity of all processes. Often, a lack of hemoglobin causes a decrease in blood pressure.

Pregnancy

The reason for the constantly low temperature in pregnant women may be endocrine system disorders. Especially often the thyroid gland is to blame for this. A decrease in temperature can be a symptom of hypothyroidism, which is expressed in a lack of thyroid hormones. Iron produces them too little.

Pregnant women are characterized by a decrease in temperature with prolonged and persistent toxicosis. The body also produces a reaction in the form of a decrease in temperature with poor nutrition, since after eating the temperature rises to normal.

Another problem that low degrees signal is a weakened immune system. It is likely that the pregnant woman is showing symptoms diabetes. In this case, nausea, vomiting, sticky sweat join the temperature drop.

Diabetes

A decrease in temperature in diabetics can be due to two reasons:

lack of glucose;
with a sufficient level of glucose, the impossibility of its proper processing and, as a result, starvation of the body, lack of energy.

With a serious decrease in temperature or with sharp jumps in values for diabetes, it is better to consult your doctor - this indicates serious problems.

internal bleeding

A sudden and unexplained decrease in body temperature may be associated with internal bleeding. Moreover, this problem occurs in both acute and chronic bleeding. Prerequisites for internal bleeding: weakened walls of blood vessels, stomach ulcers, tumor growth.

Vascular problems

Problems with blood vessels often entail violations of heat transfer. Often the reason for the decrease in temperature in this case is the poor patency of the vessels or their weak filling, which leads to a lack of nutrition of the skin and, accordingly, a decrease in temperature.

Also, the vessels can expand, which causes a decrease in temperature.

A vascular problem can be caused by the presence of a pressure bandage or by wearing shoes that are too tight.

Intoxication

A decrease in body temperature can be a reaction of the body to intoxication - poisoning.

Poisoning is caused by various substances:

mushrooms;
Food;
medicines;
alcohol and drugs;
toxic substances.

Intoxication is manifested in the inhibition of the most important functions of the body (cardiac activity, respiration), which leads to a decrease in temperature.

hypothermia

Prolonged hypothermia can significantly reduce the thermal performance of the body. Such cases are not uncommon even in a relatively warm room with high humidity or when in wet clothes.

Before going out, it is important to dry your head. Often low body temperature is associated with hypothermia

You can not go out with a wet uncovered head, even if there is +10°C, it also threatens with hypothermia.

Starvation

During the fasting period, the temperature drops due to a lack of energy, nutrients, weakening of the body. Adherents of strict diets and therapeutic fasting need to carefully control their body temperature and the state of the body as a whole.

Unbalanced nutrition and starvation often lead to serious health problems. A decrease in temperature signals that the body needs vitamin support.

Skin diseases

A decrease in body temperature can provoke skin diseases. Blood microcirculation worsens in some areas, thermoregulation as a whole is disturbed, the result of this is a decrease in temperature. Diseases that provoke a decrease in body temperature include psoriasis, ichthyosis, dermatitis, eczema.

The decrease in temperature occurs for several reasons:

vascular damage;
violation of blood microcirculation;
insufficient nutrition of the skin;
intoxication associated with skin damage.

With ichthyosis, the epidermis becomes keratinized, which leads to a change in heat transfer. Large areas of affected skin, such as psoriasis or dermatitis, require increased blood flow, reducing overall body temperature.

Sepsis

When blood is infected, bacteria in the body multiply at a fantastic rate, poisoning their carrier. Most often, this process is accompanied by a strong increase in temperature. However, if a person is weakened, the opposite effect can be observed.

In severe cases, the temperature drops below 35°C, the cause is a problem with the central nervous system and the thermoregulation system is turned off. In such a situation, it is necessary to take immediate measures, since the body is practically unable to resist, death may occur.

Skin lesions, trauma

Significant skin lesions (injuries) cause a decrease in temperature. Since injuries and wounds are accompanied by blood loss, there is a general weakening of the body, low pressure, which in turn leads to a decrease in temperature.

adrenal glands

Lowering the temperature can cause disorders in the work of the adrenal glands. Insufficient production of cortisol or sex hormones will not only lower the temperature, but also cause other painful symptoms - fatigue, irritability, lowering pressure.

Hypothyroidism

The thyroid gland can also cause a decrease in body temperature. With insufficient production of hormones, the temperature drops.

A brain tumor

Oncological diseases provoke a low temperature. This symptom is especially common in tumors on the hypothalamus. It is there that the center responsible for thermoregulation is located. With the growth of a tumor, malignant or benign, the body temperature drops.

Asthenic syndrome

With asthenic syndrome, a person suffers from many symptoms:

violations of coordination of movements and balance;
vision problems;
shortness of breath;
weaknesses;
dizziness;
pallor of the skin;
lethargy.

A decrease in temperature in this case is observed against the background of a general weakening of the body associated with a lack of oxygen in the tissues. Constantly low body temperature may be a sign of one of the immune diseases. For example, AIDS patients complain about such a problem.

Which doctor to contact with low body temperature

If the temperature is low, you need to consult a therapist. It is he who directs everything necessary examinations. Be sure to pass urine and blood tests. If a disease is detected or suspected, the doctor will refer you to a specialist.

Low body temperature in a child - what to do

In the presence of such signs, the doctor should be called urgently:

lowering the temperature to 34 ° C, with its further decrease;
severe malaise, accompanied by loss of consciousness;
a sharp drop in blood pressure, hearing and vision impairment, vomiting, loose dark stools.

First of all, it's important not to panic.. For babies under three years old, a low temperature can be a variant of the norm, as well as an increased one. Unformed thermoregulation mechanisms can play a bad joke in an excessively warm or cool room, so it's worth checking if the child is cold.

In case of mild hypothermia, it is enough to dress (cover) him warmer and give him a warm drink. If the problem is not related to hypothermia, you should contact your pediatrician.

Also, the cause of a low temperature in a child may be a metabolic disorder or vitamin deficiency. In any case, without a doctor's prescription, it is better not to take drastic measures, as this can harm.

Low body temperature with menopause - how to treat

With menopause, a lower temperature is possible. The body during this period reacts to changes in the hormonal background, which provokes temperature fluctuations. Often, after a strong tide, the temperature drops. This is due to heavy sweating. Due to a decrease in estrogen production, immunity decreases, which provokes a decrease in indicators on the thermometer.

What to do if the temperature is lowered with a cold

Low temperature with a cold requires proper rest. You can use the old methods and steam your legs, drink herbal tea with honey. Warm dry compresses and a warm blanket help many people.

Do not get carried away with symptomatic drugs - they have antipyretic properties. During this period, you need to consume more vitamins and only warm drinks in large quantities.

Ginger root

Ginger has a warming and immunostimulating effect, which makes it an indispensable assistant in reducing the temperature. Ginger tea or compresses, adding fresh root to cooked dishes have a positive effect on the body, not only at low temperatures.

Leaves of willow-herb and stinging nettle

Fireweed and nettle are known for their stimulating properties. A decoction of these herbs will help to cope with a decrease in temperature.

Coffee

Coffee raises the temperature if you eat 3 tsp. ground coffee without drinking water.

Baths and compresses

A hot bath can provoke Negative consequences up to and including death. You should not take a bath, the temperature of which exceeds 37 ° C - this is the optimal temperature to warm the body.

At low temperatures, you can use warm dry compresses or their alcohol version. The main thing is not to burn the skin - napkins or towels should not be too hot, and it is better to dilute alcohol with water.

Herbs and seasonings to raise the temperature

Spices used in cooking can also raise the temperature. For example, cinnamon improves blood microcirculation, so adding a little spice to tea can raise the temperature.

The most popular spice - pepper - has the same properties. When the temperature drops, any kind of it is used, the main thing to remember is that the hotter the pepper, the more effectively it affects the body temperature.

Among the herbs that raise the temperature, sage and oregano can be distinguished. Fragrant plants perfectly stimulate the body.

If the state of health at a low temperature is satisfactory, there is no weakness in the body, and the temperature itself is kept within 35.5-36 degrees, it is considered that this is a variant of the norm. In other cases, when the condition is accompanied by rapid fatigue, other pathological symptoms join, or the temperature drops below 35.5 ° C, we should talk about pathology.

A temperature of 35.5, which lasts for a long time, is often a signal of trouble in the body

We take care of our health when the thermometer is creeping up, but we often do not pay attention to the breakdown. However, a temperature of 35.5, which lasts for a long time, is often also a signal of trouble in the body. Why is there a low temperature?

You should be wary if for a long time the values on the thermometer do not rise above 36-36.2 ° C.

Several causes of low temperatures

1. Past illness.

If you have recently had the flu or an acute respiratory disease, it is not surprising that your temperature is lowered. The body has not yet fully recovered from the disease and cannot work to its full potential.

2. Exacerbation of chronic diseases.

A low temperature often indicates an exacerbation of chronic diseases.. If old sores again reminded of themselves, then you should consult a doctor and undergo a course of treatment in order to permanently eliminate the insidious cause of low temperature.

3. Overwork.

Rush at work, lack of sleep, sedentary lifestyle, unhealthy diet- all this leads to the fact that the body is depleted, and the forces literally leave us.

In this case, a decrease in activity, rest, moderate physical exercise especially morning exercises.

Very helpful cold and hot shower and outdoor walks. You can drink a course of multivitamins, and before going to bed take an infusion of valerian or motherwort.

4. Diseases of the adrenal glands.

With such a problem, you should consume more water.(in the absence of contraindications) and try lean in season on melons and watermelons, perfectly cleansing the body and healing the adrenal glands.

5. One of the causes of low body temperature may be hypothyroidism (reduced activity of the thyroid gland).

Improper functioning of the thyroid gland leads to a malfunction in the functioning of many organs.
So, if you suffer from malaise, weakness, are often irritated, feel a breakdown, your hands and feet are cold - measure your body temperature, it may be lowered.

And don't ignore these symptoms. Remember: low temperature is no less dangerous than high temperature., because in this case the body becomes more vulnerable to the attack of bacteria and viruses.

Before you raise your body temperature from the inside, you need to raise it from the outside. To do this, lie down and cover yourself with several blankets. First of all, heat enters the body through the legs, so you need to cover them plastic bottles filled with hot water, or heating pads.

You can also make warm foot baths. For best effect it is recommended to add a few drops of eucalyptus aroma oil to the water.

Raise body temperature and infusion of St. John's wort: 1 tbsp. l. Pour raw materials with 1 cup boiling water.

If after 2-3 days the temperature does not return to normal, you should definitely consult a doctor and undergo the necessary medical examinations. published .

Have questions - ask them

If a person has a temperature of 36, what does this mean? To answer this question, you should find out what kind of indicator it is, because you need to know as much as possible about everything that is the norm for a person. A complex process of interaction between various organs and tissues, intracellular energy reactions create a strictly defined thermal background of the body of warm-blooded animals - birds and mammals, including humans.

The concept of "body temperature"

Animals capable of retaining their body heat within narrow limits regardless of conditions environment, called These include mammals and birds. Animals deprived of this ability are usually called cold-blooded (poikilothermic). The process of maintaining temperature is called thermoregulation.

Cold-blooded animals have unstable body temperature, which is most often close to the parameter of the external environment. Warm-blooded animals, to which humans belong, have an almost unchanged indicator. The highest value was noted in birds. It varies within 40-41 ° C. Mammals "warm up" to 32-39°C, depending on the species. In humans, values in the range of 36-37 ° C are considered normal.

Normal body temperature

What does a temperature of 36.2°C mean? The latter showed that the norm fluctuates within 36.2-37.5 ° C. Well, if the temperature is 36.0 ° C - is this considered the norm? You should know that this indicator different ethnic groups often differ. For example, the Japanese norm is only 36 ° C. In Australia and America, the average reaches 37 ° C.

It is also important to know that there are different temperatures in different parts of the human body. For example, in the armpits it is higher than in the neck and face. Even on the skin of the feet and hands, and the lowest - on the toes. There are 2 types of temperature: internal organs and skin. Organs have a different temperature, which depends on the activity of the ongoing processes. The temperature of the internal organs, as a rule, exceeds the temperature skin on average by 0.3-0.4°C. The "hottest" liver is about 39°C.

By measuring the temperature on the toes, you can determine the rate of metabolic processes in the body. If a person has warm lower limbs, then it has a high rate of metabolic reactions, if cold - low.

How to measure the temperature correctly?

Often a person feels unwell, and at the same time he has a temperature of 36. What does this mean? Usually the value is normal and should not arouse suspicion. A person's temperature can fluctuate between 36-37 ° C. However, a slight decrease in it and a breakdown, as a rule, indicate the presence of certain diseases.

It is very important to be able to measure the temperature correctly. This can be done in several ways: in the mouth, in the armpit, in the rectum.

However, the results may vary slightly. it is usually 0.5 degrees lower than in the rectum, and the same amount higher than the temperature measured in the armpit.

What does a temperature of 36.9 mean? In Russia, for measurement, it is often the armpit that is used for measurement. It is noteworthy that this method is not very reliable, since with it a person receives inaccurate results. When measuring temperature in this way normal value is 36.3-36.9°C.

In European countries, measurement in the oral cavity is common. This method is considered quite reliable. If, when measured by this method, the temperature is 36.8, what does this indicator mean? This value is normal, because when measuring the temperature in the mouth, it can fluctuate between 36.8-37.3 ° C. However, you should be aware that this method contraindicated in small children under the age of 5, people with irritability and mental illness.

Rectal gives the most accurate result, since the temperature in the rectum is closer to the temperature of the organs. The norm in this case is 37.3-37.7 ° C.

Before the operation, the patient has a temperature of 36 - what does this mean? Artificial lowering of temperature in medicine is not uncommon: it is lowered in this case on purpose.

At temperatures above 42 ° C, brain tissue is damaged in humans. If it falls below 17-18 ° C, death will occur.

It's important to know

If the temperature is 36, what does this mean? Norm or deviation? For each person, this indicator changes during the day in the range of 35.5-37.0 ° C, and this is considered normal. It is lowest in the morning and reaches its maximum in the evening.

Low body temperature (36 ° C) falls within the acceptable range. But if it dropped below 35 ° C, this indicates the presence of some serious illness. When the temperature drops to 32.2°C, the person falls into a stupor. At 29.5°C, a person will lose consciousness and die if it falls below 26.5°C.

The temperature can be influenced by the age and gender of the person. For example, in girls it stabilizes by the age of 13-14, and in boys - by about 18. The average temperature in men is 0.5-0.7 ° C lower than in women.

Elevated temperature

What does a temperature of 36.9°C mean? Is this indicator a sign of illness? Usually, an increase above 37 ° C indicates a disease. This symptom is quite common and can be observed in various ailments and diseases. A dangerous condition for a person is considered to be non-decreasing for a long time. At elevated temperature you should definitely consult a doctor to find out possible cause. If it reaches 41 ° C and above, you should immediately call an ambulance.

What to do at high temperature?

The most important thing to do is to see a doctor. You should start with an examination by a therapist. He will conduct an examination and appoint a series of studies. During the visit, be sure to examine the lymph nodes.

Then you need to pass a urine and blood test, do an ECG, ultrasound of the kidneys and organs abdominal cavity, kidneys, to be tested for dysbacteriosis.

Although human body can not function normally at too low or too high a temperature, there are cases when a person managed to survive. So, according to information obtained from the Guinness Book of Records, Maximum temperature in history was recorded in 52-year-old Willie Jones, who was admitted to Grady Memorial Hospital on July 10, 1980. He suffered heat stroke, while his body temperature was 46.5 ° C. The patient spent 24 days in the hospital, after which he was safely discharged.

The person with the lowest documented temperature was two-year-old Karlie Kozolofsky, who on February 23, 1994, accidentally spent 6 hours in the cold. After a long stay in the cold (-22°C), her body cooled down to 14.2°C.
