Temperature 37.1 lasts for 5 days. Low-grade fever without symptoms

And sometimes the body temperature remains normal throughout the day, but invariably rises in the evening.

This phenomenon does not always indicate the development of the disease, but it still indicates certain changes in the human body.

For some people, such changes generally become a normal condition, because this is how their thermoregulatory system functions. And yet you should very carefully 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 have any complaints 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 such 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 disadvantage.

A person rarely resorts to using a thermometer unless there are additional health complaints or signs of illness. But after taking periodic measurements, you may be surprised that there is a temperature of 37 in the evening, but not in the morning.

The 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 observed);
rhythm of life (people with an active lifestyle have higher thermometer readings);
type of measuring device (it is generally accepted that electronic thermometers have an error, unlike mercury devices);
time of year 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 occur due to a specific threat. Very often it is a consequence of overload or hormonal changes in the body.

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

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

Among women

Many women periodically experience increased body temperature. This is why this happens. Hormones are constantly produced during the menstrual cycle.

On certain days, the release of some substances becomes greater and others less. Immediately after ovulation (the release of an 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 it, smooth muscles relax. Progesterone also affects thermoregulation and reduces the rate of heat transfer.

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

As soon as bleeding begins, progesterone levels will decrease and the thermometer readings will return to normal.

If pregnancy has occurred, elevated values may persist for several months until the placenta is formed. For expectant mothers, it is considered normal 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 rate, reflex effects when drinking alcoholic beverages, or normal thermoregulation processes.

Reasons why the temperature rises to 37 in the evening:

during premenstrual syndrome
during pregnancy
when feeding a baby
during ovulation
shortly after the birth of children
during menopause
after eating too much and too much food
with excessive consumption of strong alcoholic drinks
with significant overheating in the sun, etc.

For some women, such a temperature is generally normal, accompanying them throughout their lives.

For other ladies, the numbers often change in the evening due to increased fatigue or severe nervous tension.

In men

Representatives of the stronger sex also often complain that in the evening the temperature rises to 37 degrees without symptoms.

This may be a consequence of hypothermia or overheating, injury, or nervous strain.

Hyperthermia can occur due to excessive consumption of spicy foods or addiction to alcoholic beverages.

The temperature may rise in the evening due to significant muscle strain after heavy physical work or intense sports training.

The most common cause could be taking a long bath or shower that is too hot, sleeping for a long time in a chair next to the radiator, or wearing a very warm dressing gown or suit.

In older people, temperature fluctuations may have their own characteristics. During the day, for example, there will be some hypothermia, and by the evening the numbers will creep up 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

A child often causes his parents great anxiety due to the temperature rising in the evening.

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

Most often, an increase in temperature at night occurs shortly after an infection or other childhood illness.

The baby’s immunity is 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 protective forces of the child’s body are guarding his health.

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

Overly active games
clothes that are too warm
reaction to vaccination
teething
hot drink at night
too warm blanket
change of biorhythms
a hearty dinner
unsettled metabolism, etc.

In newborns and premature babies, a temperature of thirty-seven degrees in the evening is not uncommon and is associated with the formation of normal thermoregulation processes in the baby’s body.
Such reasons are the most common and all parents face them.

Children's nervous and vascular systems are not yet fully formed, so they react very quickly to any change in the external or internal environment.

An overly sensitive child's temperature may rise even when crying a lot or watching an interesting movie.

The baby’s digestive system can also react with an abundant release of enzymes and active intestinal activity, which is why the temperature rises to 37 in the evening.

Therefore, children’s temperature is measured only after special preparation. The thermometer should be placed 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. It is advisable to measure the temperature before dinner and water procedures.

Eating

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

A noticeable increase in temperature occurs in individuals with good metabolism. Most people don't feel these changes, but if you take your temperature immediately after eating, you'll be surprised.

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

Overwork

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

There is such a thing as chronic fatigue syndrome. In people with this diagnosis, the temperature may 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 it is worth thinking about the presence of a pathological cause of this condition.

Reasons for rising temperature

Not always, when the thermometer registers thirty-seven, this only speaks of harmless functional reasons. Often such numbers indicate the development of a disease.

Such jumps may be the first symptom:

Helminthiasis
inflammatory process in the body
introduction of infection
development of malignant neoplasm
cardiovascular pathology
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 may be associated with intoxication by cell breakdown products, the fight against pathogenic microorganisms, or impaired neuromuscular conduction.

It is also possible to become infected with infectious diseases, so consulting a doctor in this case is mandatory.

Pathological conditions

If a person’s temperature rises to 37 in the evening, this may be an alarm bell. There are many pathological causes for this condition, but they all usually have additional symptoms. Busy people leading an active lifestyle may not even notice them.

Colds

The most common symptom of a cold is an increase in temperature. In this way, the human body tries to cope with the infectious agent. It is known that viruses die when the thermometer reaches 38 degrees. Therefore, you should not lower the temperature to 37. Allow your body to eliminate the infection on its own and build immunity.

Consequences of infection

Many infectious diseases occur with elevated temperature. But what if you are already healthy and it still continues to rise? This outcome is also possible. It is in the evening that the thermometer increases noticeably.

Such symptoms are especially common due to chickenpox, acute intestinal infection, and bacterial pathologies. Don't worry, your body will regain its strength in the near future. Such temperature indicators do not require the use of antipyretics. After a night's rest, they return to normal on their own.

Arterial pressure

Hypertensive patients often complain that they have an elevated 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 the blood pressure back to normal, the thermometer shows lower numbers.

Hypotonics, on the contrary, have. For some people it drops to 36 degrees. It is very important not to miss the moment. But if this condition does not cause discomfort, then there is no need to try to correct it.

VSD

This abbreviation stands for vegetative-vascular dystonia. Until now, this disease remains incompletely studied.

Many doctors refute it, saying that the person is dealing with chronic fatigue syndrome. One way or another, with vegetative-vascular dystonia, the thermometer readings increase. A person may note that in the morning the temperature is 36, in the evening – 37.

Oncological pathologies

It is the evening increase in thermometer values that often forces a person to turn to specialists. During the examination, tumor processes may be detected.

Benign neoplasms often do not make themselves felt with such symptoms. But the proliferation of cancer cells affects the lymphatic system, so a slight increase in the readings of the mercury meter is the first alarm bell.

Immune diseases

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

allergy;
rheumatic diseases;
blood pathologies;
system deviations.

Many diseases develop due to increased immune function of the body, which provokes inflammation of various types.

What is low-grade fever, and how to deal with it?

Low-grade fever is an unreasonable increase in the temperature of the human body. In such cases, the readings 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 causes of increase.

The main sign of low-grade fever 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;
rapid pulse;
neuroses and insomnia.

Both a specialist and the patient himself can pre-diagnose the problem. But with low-grade fever, additional research is necessary. To do this, consult a doctor and find out why the temperature rises to 37 in the evening.

Diagnosis of low-grade fever

Before making a diagnosis, the specialist must examine the patient. The condition of the mucous membranes, the functioning of the respiratory system are studied, and the abdominal organs are palpated.

Defects in joints and lymph nodes are detected. Women undergo a gynecological examination and palpation of the mammary glands, and the menstrual cycle is studied. Anamnesis collection is carried out in several stages.

The doctor determines the following:

whether there have been surgical interventions or injuries in the recent past (for women - childbirth and abortion);
what infectious diseases have been suffered during life and whether there are chronic pathologies (particular attention is paid to diabetes, HIV, liver and blood diseases);
the possibility of hepatitis and bacterial endocarditis.

Such a survey will allow the doctor to get a general idea of the person’s condition. After this, he will measure his body temperature and blood pressure, perform percussion and auscultation.

Usually, already at the examination stage, the specialist notices a rash on the body, a change in the color 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 infestation.

To do this, the specialist will send the patient for laboratory tests.

To clarify the reason why his temperature is always 37 in the evening, you need to go through:

clinical and biochemical blood test
four mandatory tests (HIV, syphilis, hepatitis B and C)
allergen panel
general urine analysis
stool analysis for worm eggs and protozoan cysts
sputum microscopy
discharge from the urethra and genitals
biopsy
spinal puncture.

The results obtained help identify helminthiasis, inflammatory processes 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 makes it possible 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 final confirmation of the diagnosis by conducting instrumental studies. For this purpose, mammography, FGDS, angiography, ultrasonography, etc. are used.

They quite accurately allow you to identify the disease due to which there is a regular rise in temperature, as they show the condition of the patient’s internal organs. In addition, they make it possible to correlate the general picture of the disease with the altered thermal regime.

Quite often, children and adults experience an increase in body temperature to 37.4 °C. What does it mean? Most people consider this temperature to be a clear sign of infection and often start taking antipyretics, symptomatic cold remedies, or even antibiotics. In fact, there are many reasons for a temperature of 37.4 °C. And not all of them are of an infectious-inflammatory nature. Therefore, even before using any means, it is necessary to find out why the temperature rose to 37.4 °C. In this case, the doctor must evaluate all existing symptoms and the history of the disease, and then prescribe an examination.

Reasons for the temperature increase to 37.4 °C

Why can body temperature rise to 37.4 °C? The main factors include:

Acute respiratory infections, influenza, infectious mononucleosis, colds with damage to the upper respiratory tract. In this case, a temperature of 37.4 °C is accompanied by a runny nose, cough, weakness, and sore throat. Viral infections lead to intoxication. In this case, there is a headache, possible aching sensations in the muscles and joints, a feeling of exhaustion, and a significant decrease in performance;
infectious and inflammatory diseases in the acute stage, exacerbation phase, or sometimes even hidden. This group includes pyelonephritis, cystitis, bronchitis, tonsillitis, sinusitis (and other sinusitis), otitis;
intestinal infections of bacterial and viral nature;
purulent lesions of soft tissues and bones, septic complications;
tuberculosis;
early postoperative period. The more extensive the surgical intervention, the more likely the temperature is to rise. In the absence of complications, a temperature of up to 37.4 °C lasts for several days;
hormonal changes.

Is a temperature of 37.4 °C dangerous?

In itself, a temperature of up to 37.4 °C does not threaten human life. It does not leave irreversible consequences and disappears without a trace after the root cause is eliminated. The discomfort experienced by the patient subjectively is not due to the effects of temperature, but to the intoxication that occurs against the background of the primary disease (headache, weakness, deterioration of well-being, etc.). This happens, for example, with viral and bacterial infections.

Temperatures up to 37.4 °C are not dangerous. But the diseases that cause it can be quite severe, especially if complications develop. For example, influenza can lead to toxic damage to the brain and increased permeability of small blood vessels. Otitis media is fraught with secondary meningoencephalitis due to the risk of infection spreading through the inner ear deep into the skull. Repeated streptococcal tonsillitis threatens the development of rheumatism, bacterial infectious and inflammatory diseases can be complicated by sepsis (blood poisoning).

Is it possible to reduce the temperature to 37.4 °C and how to do it?

Reducing the temperature to 37.4 °C is not recommended. Indeed, in most cases, it indicates the active functioning of the immune system, accelerates the formation of protective complexes during infectious processes and creates unfavorable conditions for the proliferation of certain pathogens. But sometimes an elevated temperature is combined with unpleasant signs of intoxication, a runny nose and a painful feeling of nasal congestion. In this case, the use of symptomatic remedies is permissible. This is the name for drugs that do not treat the underlying disease, but alleviate the condition of the patient. Currently, complex action products are being produced to reduce the severity of several symptoms at once, for example the drug RINZA®. Providing an antipyretic and analgesic effect, it helps relieve the main symptoms of colds, flu or ARVI. The use of drugs can be combined with non-drug measures: drinking plenty of fortified drinks, cool rubdowns, taking herbal remedies with a mild diaphoretic effect (raspberry, linden blossom).

Temperature 37.4 °C in a child

In children, elevated body temperature is detected quite often, which is a cause for particular concern for parents. However, it is not always caused by some kind of inflammatory disease.

Why can you have a temperature of 37.4 °C without symptoms?

An asymptomatic increase in temperature is usually detected by randomly measuring it, because the person does not feel any signs of ill health. This happens, for example, when visiting a doctor to undergo a comprehensive preventive examination, obtaining a certificate of admission to the pool or vaccinations. An increase in body temperature to 37.4 °C without symptoms is possible with neuroses, previous head injuries and for a number of other reasons. Women often experience a similar condition in the luteal phase (the period from menstruation to ovulation), in the first trimester of pregnancy and at the beginning of menopause. The cause of an asymptomatic increase in temperature can be quite serious, so if the elevated temperature persists for a long time, you should consult a doctor for advice.

What to do if the temperature of 37.4 °C does not go away for a long time?

The duration of the period of temperature increase is usually short, it normalizes as the inflammation subsides and the infection is eliminated. If this does not happen, a thorough diagnosis must be carried out. This will allow us to identify complications and concomitant diseases, and determine non-infectious causes of the condition.

RINZA® and RINZASIP® with vitamin C at a temperature of 37.4 °C

If a temperature of 37.4 °C is combined with a runny nose, sore throat, chills, headache, “ache” in the joints and muscles, along with antimicrobial drugs, it is possible to use symptomatic drugs. The drugs in the RINZA® and RINZASIP® line help alleviate the condition, help reduce the severity of the main symptoms of a cold and lower body temperature.

A slight increase in temperature may occur due to exposure to external factors or processes occurring within the body. If such a symptom is observed for several days, then it should be considered as a pathology that needs to be studied and treated.

Reasons for temperature rise to 37 degrees

For many years, medical experts have been searching for an answer to the question of why people's body temperature rises from time to time. As a rule, abnormal indicators that quickly disappear cannot be called dangerous. Such conditions are usually caused by the following factors:

Hormonal changes during pregnancy, breastfeeding or menstruation.
Decrease in the amount of hemoglobin in the blood. This deviation is usually called anemia.
Experiencing stressful situations that cause the body to release large amounts of adrenaline.
A feeling of chronic fatigue that lasts for at least a month.

These reasons cause a short-term increase in temperature. Therefore, there is no need to worry about them.

If a person maintains a temperature of 37 degrees for a long time, then his immune system may be severely weakened. A painful symptom appears due to the fact that the body fails to naturally remove toxic substances that poison it. To correct this situation, he carries out an increase in metabolic rate. Against this background, a slight increase in temperature occurs.

In pregnant women, this symptom lasts a long time. The malaise appears due to the accumulation of waste products in the blood of the fetus developing in the womb. The strange thing is that the anomaly can bother a woman for just 1 day or for a whole week.

Temperature reactions often accelerate against the background of a decrease in the body's energy reserves and a slowdown in biological reactions.

Nervous disorders often cause body temperature to rise to 37 degrees. This symptom indicates a malfunction of the thermoregulation center of the brain. If a person experiences stress constantly, then malaise will bother him for quite a long time.

The temperature never rises without any reason. In any case, there will be a factor that provokes this condition. A person may simply not notice it. Under such circumstances, an increase in temperature will indeed cause surprise.

What diseases are accompanied by a temperature of 37 degrees

If a person does not see a good reason why his temperature could rise, then this symptom indicates a hidden infection. Usually it does not manifest itself with severe symptoms. However, if left untreated, the disease will cause serious harm to health.

The patient may have the following types of hidden infections:

Pathologies of the respiratory system. A change in temperature is observed at the initial stage of development of a respiratory disease. If the cold is mild, a person does not have other symptoms characteristic of such a condition. The disease will make itself felt only in the evening with a slight increase in normal body temperature.
Chronic sinusitis and tuberculosis. In this case, a temperature of 37 degrees can be observed for a long period, which is calculated in months. During the daytime, this indicator will correspond to the norm. The deviation appears only in the evening.
Infections of the genitourinary system. Pathologies such as cystitis and pyelonephritis usually occur without pronounced symptoms in the prodromal period. Distinctive signs are detected only several weeks after infection.
Rheumatism. It may have the form of pathogenic streptococcus, which has a detrimental effect on the condition of the heart valve. The disease can be recognized by an increase in temperature to 37 degrees. It usually lasts 2 weeks or longer.
Bacterial infection. With diagnoses such as measles, rubella or mumps, there are also no visible signs of illness. A slightly elevated temperature in this case is the only sign of the disease.

As one might understand, most latent diseases, in which a temperature of 37 is observed, occur with virtually no symptoms. Because of this, a person ignores a slight ailment and refuses a recommended visit to a specialist.

In what cases is an increase in body temperature not dangerous?

Not all cases of body temperature rising to 37 degrees are dangerous to health and life. In some situations, this ailment should not be considered as a pathological process requiring immediate treatment.

There is no need to worry if an adult’s body temperature has risen for the following reason:

Severe fatigue.
Recent experience of a stressful situation.
Prolonged exposure to the sun or in a room in which there is no normal air ventilation.
In the presence of vegetative-vascular dystonia.

Another group of factors should include adolescence. During this period, the body experiences serious changes. Therefore, an increase in temperature to 37 degrees is a completely natural process.

In childhood, such ailment, which does not require urgent treatment, appears in a number of cases:

Overheating of a child in winter or summer due to the wrong choice of clothing. To solve the problem, just change the baby's clothes. Overheating is indicated by a symptom such as a child's sleepy and apathetic state.
Eruption of the first teeth. This process is almost always accompanied by an increase in temperature. As a rule, after a couple of days the baby’s condition returns to normal.
Infection. If this is the reason, it is enough to give the child a suitable antipyretic drug. Temporary monitoring of the baby’s condition is also allowed. After all, such infections are usually not very dangerous, so the child’s body is able to cope with them on its own.

If parents are unsure whether they should take measures to reduce their child’s body temperature, they can always contact their pediatrician and consult with him on the problematic issue.

Do I need to take antipyretics?

Experts do not recommend uncontrolled use of antipyretics. This category of medications has a lot of side effects. It is for this reason that they should be used for medicinal purposes only in emergency cases. Before you take it, you must find out the cause of the ailment.

The patient can take an antipyretic to bring down the temperature to 37 degrees in the following conditions:

Cardiovascular diseases.
Disturbance in the functioning of the respiratory tract.
Impaired functioning of the nervous system.
Convulsive reaction to temperature.

If a person just feels slightly unwell, he should try to reduce his temperature with hot tea, to which a slice of fresh lemon has been added.

How to get rid of a slight increase in body temperature

A slight increase in temperature in a child or adult is not a good reason to immediately call an ambulance. This deviation can be eliminated at home. Doctors recommend taking the following actions:

Ventilate the room in which the patient is located. It is advisable to repeat the procedure several times a day.
It is necessary to ensure that the patient is dressed in dry clothes. If he sweats frequently due to illness, he should be changed.
You should not try to reduce the temperature to 37.5 degrees with antipyretic drugs. Even a weakened body can cope with such a deviation without outside help.
You can wipe certain areas of the patient's body with a damp cloth or towel.
If the temperature begins to rise even more, the patient will need to be given medicine to alleviate his condition.
It is impossible to limit the patient to a sufficient amount of drinking water. Due to the temperature, severe thirst wakes up, which is a sign of a lack of fluid in the body.

Every home first aid kit must contain antipyretic medications. After all, a person does not always have the opportunity to quickly go to the pharmacy for the necessary medicine, since this symptom usually manifests itself spontaneously and at night.

When a doctor's help is needed

In some situations, you should never delay contacting a specialist. This applies to the following situations:

The patient persistently refuses to eat even after his temperature has become normal.
A slight twitching of the chin is noticeable, which indicates a seizure disorder.
Unnatural changes in breathing have occurred. The patient began to breathe more deeply and less frequently. Shallow breathing is also a cause for concern.
The patient sleeps a lot even during the daytime.
The skin of the face acquired a pale tint.

If you detect at least one symptom, you should immediately consult a doctor for help.

A person requires a full examination if his body temperature rises to 37 degrees over a long period of time. This symptom should especially not be ignored if it is not accompanied by any other abnormalities.

If a person’s temperature rises again, he can try to bring it down using proven methods:

You should take a supine body position. In a state of rest, the psycho-emotional background normalizes faster and the nervous system returns to normal.
It wouldn't hurt to have an aromatherapy session. Orange and tea tree oils have a beneficial effect on body temperature.
It is necessary to apply clean gauze or a towel soaked in a vinegar solution to the forehead. It is advisable to keep this compress for about 15 minutes. Afterwards it should be replaced with a new one.
Drinking tea with raspberry jam will be of great benefit.

If these methods do not help, and the body temperature continues to rise, then it will not be possible to do without antipyretics.

A fever that occurs without other symptoms is a cause for concern. Especially if it increases over a long period of time. In case of such ailment, you should undergo a full examination of the body for abnormalities and hidden infections. It is unlikely that it will be possible to find out the cause of such ailment in any other way.

A prolonged increase in body temperature, even to a slight level, may indicate a dangerous pathological process that must be eliminated in a short time.

Attention, TODAY only!

“I have a temperature,” we say when the thermometer rises above +37°C... And we say it wrong, because our body always has an indicator of the thermal state. And the mentioned common phrase is pronounced when this indicator exceeds the norm.

By the way, a person’s body temperature in a healthy state can change during the day - from +35.5°C to +37.4°C. In addition, we get a normal indicator of +36.5°C only when measuring body temperature in the armpit, but if you measure the temperature in the mouth, then you will see +37°C on the scale, and if the measurement is carried out in the ear or rectally, then all +37.5°C. So a temperature of +37.2°C without signs of a cold, and even more so a temperature of +37°C without signs of a cold, as a rule, does not cause much concern.

However, any increase in body temperature, including temperature without signs of a cold, is a protective response of the human body to an infection, which can lead to a particular disease. Therefore, doctors say that an increase in temperature to +38°C indicates that the body has entered into a battle with the infection and has begun to produce protective antibodies, immune system cells, phagocytes and interferon.

If a high temperature without signs of a cold lasts long enough, then the person feels unwell: the load on the heart and lungs increases significantly, as energy consumption and the need of tissues for oxygen and nutrition increase. And in this case, only a doctor will help.

Life "under the degree"

10 reasons why your temperature may rise

1. The disease begins suddenly, usually with chills, body aches and pain in the eyes. The temperature quickly rises to 38 - 39 degrees, its fluctuations are insignificant during the day. Can last for 4 - 5 days.

It looks like the flu, especially since it's the right season. Other acute respiratory viral infections also occur with an increase in temperature, but more often not so high.

2. The temperature suddenly rises to 39 - 40 degrees, a severe headache appears, pain in the chest, intensifies when inhaling. There is a feverish blush on the face, and herpes may become active on the lips. After a day, brownish sputum begins to leave.

This is how pneumonia occurs. It involves a segment or lobe of the lung (sometimes it is bilateral). True, now more and more often this disease occurs in a blurred form.

3. During the day, the temperature jumps to 38 - 39 degrees. A rash appears all over the body. Before this, there may be weakness and runny nose for several days. Adults get sick more severely than children.

It looks like you have caught measles, or rubella, or scarlet fever - these infectious diseases are very similar in the initial stages. Characteristic signs help to make a correct diagnosis: with rubella, the lymph nodes become enlarged, with scarlet fever, the rash is small, there is no runny nose, unlike measles, but it is often accompanied by a sore throat.

4. There is a periodic rise in temperature, often low-grade fever. White blood cells may be elevated in the blood.

It looks like there is a chronic disease going on, or there is a hidden source of infection in the body.

Elevated temperature is often the main or even the only sign of inflammatory processes. For example, exacerbation of pyelonephritis, inflammation in the gallbladder, arthritic joints sometimes do not have obvious clinical manifestations, except for elevated temperature.

5. The temperature jumps to 40 degrees at lightning speed within a few hours. A severe headache and vomiting appear, which does not bring relief. The patient cannot tilt his head forward or straighten his legs. A rash appears. Strabismus and nervous tics in the eye area may occur.

It looks like infectious meningitis - inflammation of the lining of the brain. It is necessary to immediately call an ambulance and hospitalize the patient.

6. A long-term (longer than a month) causeless increase in temperature is combined with general malaise, weakness, loss of appetite and weight. The lymph nodes become enlarged, blood appears in the urine, etc.

An increase in body temperature almost always occurs with tumors. It is especially characteristic of kidney tumors, liver tumors, lung cancer, and leukemia. There is no need to panic right away, but in some cases, especially older people, it is necessary to be examined by an oncologist without wasting time.

7. Increased body temperature, usually around 37 - 38 degrees, is combined with weight loss, irritability, tearfulness, fatigue, and a feeling of fear. Appetite increases, but weight is lost.

You need to check your thyroid hormones. A similar picture occurs with diffuse toxic goiter.

When the function of the thyroid gland is impaired - hyperthyroidism - a disorder of the body's thermoregulation occurs.

An increase in temperature is combined with damage to the joints, kidneys, and pain in the heart.

Fever almost always occurs with rheumatism and rheumatism-like diseases. These are autoimmune diseases - in them the general immune status of the body is disrupted, and leapfrog begins, including with fever.

Low-grade fever, mainly in young women, is combined with pressure changes, and there may be redness of the face, neck, and chest.

This is constitutional hyperthermia - it is more often observed in young people during nervous and physical stress, for example, during exams. Of course, this diagnosis can be made by excluding other causes of fever.

Even after a thorough examination, the cause of the fever cannot be identified. Nevertheless, an elevated temperature (38 and above) or its periodic rises for 3 weeks is recorded.

Doctors call such cases “fever of unknown origin.” We need to look more carefully, using special research methods: an immune status test, an endocrinological examination. Sometimes a rise in temperature can provoke the use of certain antibiotics and analgesics - this is drug fever.

BY THE WAY
The normal temperature of the human body - from 36 to 36.9 degrees - is regulated by a part of the brain called the hypothalamus.
Most often, an increase in temperature is a protective and adaptive factor of the body.

ON A NOTE
What will help bring down the temperature without medication:
