What happens if the temperature is low. Reduced body temperature

Anyone can experience a condition where they suddenly start to feel feverish. The reasons for this can be very different, ranging from a cold to... infectious disease. What to do in this case is no secret. It is necessary to measure the temperature, and if it exceeds 38 degrees, take an antipyretic drug.

But the completely opposite situation can happen. The patient may experience too much low temperature body (hypothermia). This condition is accompanied by the following symptoms:

• prostration;
• general weakness;
• drowsiness;
• dizziness;
• fainting;
• lethargy;
• shiver;
• slow reaction;
• irritability;
• weak pulse;
• hypotension;
• loss of consciousness;
• difficulties in movement;
• hallucinations (in especially extreme cases).

Despite the fact that a condition in which a low temperature occurs in an adult or child is rare, due attention should be given to this problem.

Is there a norm?

A long-term state of hypothermia can lead to irreversible consequences in the body, ranging from disruption of internal organs to death.

If 35 degrees is the norm for a person, then this indicates the presence of a chronic disease in his body. If the thermometer does not show more than 32 degrees, then there is a high probability for the patient to fall into a coma, and at 29 - to die.

Considering that all people have their own individual characteristics of the body, it is likely that there may be slight deviations from the norm. If the patient feels well, examinations have not revealed any pathologies, there are no complaints or chronic diseases, then this is most likely the exception that confirms the rule.

Medically speaking, the average statistical limits normal temperature are indicators from 35.5 to 37 degrees. Various factors can influence fluctuations:

• Times of Day;
• phase of the menstrual cycle;
• age;
• environmental influences;
• pregnancy;
• individual characteristics of the body.

What does this condition mean?

People who experience hypothermia for the first time wonder why this happens. In fact, there can be many reasons, let's look at the most common ones:

• decreased immunity - if you have stopped eating properly or have suffered some kind of disease, then it is likely that the body’s defenses have weakened and it takes time to restore them;
• lack of vitamins - malnutrition, adherence to a mono-diet, exclusion of any foods, as well as deficiency of fats and carbohydrates;
• infectious diseases - any disease weakens the immune system, and if they are accompanied by an increase in temperature, then excessive use of antipyretic drugs can lead to side effect and greatly reduce the temperature;
• hypothermia of the body - when cold weather sets in, be especially careful and avoid frostbite;
• long stay in cold water - if you prefer cold and hot shower or winter swimming, then please note that cold water may reduce body temperature;
• overwork;
• food poisoning or intoxication due to excessive alcohol consumption;
• decreased hemoglobin level;
• internal bleeding;
• taking certain medications - taking antidepressants or sleeping pills can cause hypothermia;
• medication overdose;
• hormonal imbalance - if a woman is pregnant or is ovulating, then temperature changes are possible;
• diseases thyroid gland;
• chronic diseases kidneys, liver;
• brain diseases;
• hypertension or hypotension;
• oncology;
• HIV AIDS;
• diabetes;
• pneumonia;
• sepsis;
• helminths;
• Acute respiratory infections - in children preschool age One of the symptoms of a respiratory disease may be a low temperature.

Diagnostics

If you have obvious hypothermia, your doctor may order the following tests:

• general urine analysis;
• general blood analysis;
• temperature measurement;
• pressure measurement;
• electrocardiogram;
• X-ray;
• hourly diuresis;
• Pulse oximetry.

How to normalize the condition?

Knowing the symptoms and causes of hypothermia, you need to understand how to act and what actions you need to take to raise your temperature.

1. If the thermometer shows less than 34 degrees, call an ambulance immediately.
2. Place the person in bed or in a place that is protected from the cold.
3. If possible, cover the entire body or at least the limbs. Leave your head open.
4. If your clothes get wet, remove them immediately and put on dry ones.
5. If the patient feels well, then you can take a bath with a temperature of no more than 37 degrees.
6. You can place a heating pad with warm water or a thermal blanket on your chest.
7. Make sure the patient drinks enough fluids. Give preference to warm tea or fruit drink.
8. Never use coffee or alcoholic drinks to raise your temperature.
9. If the patient faints or loses consciousness, and his pulse cannot be felt, begin artificial respiration before the ambulance arrives and indirect massage hearts.

If you notice temperature fluctuations, then consult a doctor immediately for any deviations from the norm. Especially if hypothermia occurs in a child. A child's body is much more sensitive than an adult and reacts more acutely to changes in the functioning of internal organs.

The hypothalamus is the area of ​​the brain responsible for the temperature of the human body. Thermoregulation in a healthy body occurs reflexively. Internal organs and skin have receptors responsible for thermal processes and cold exchange processes. When the temperature of circulating blood increases, the activity of hypothalamic neurons is activated; when it decreases, their activity also decreases. When a person has what to do, the body does not know. Receptors that determine the level of metabolism, blood circulation speed and other methods of thermoregulation disrupt their usual rhythm. As a result, the hypothalamus loses its ability to maintain the body’s usual temperature of 36.6 degrees.

What to do and how to help the body survive this syndrome? You can use pharmacological drugs, which are taken on the recommendation of a doctor. These include tenoten and persen, but you should not take them on your own, since the reason that led to this disorder is important, and only a doctor can identify it.

Low temperature is a temperature that does not reach 35.8 degrees. This indicator may be influenced by overwork, illnesses the person has suffered, or exacerbations of chronic ailments. Bacterial and viral infections may cause a decrease in temperature. In these cases, the reason, as a rule, lies in the excess content of toxins - products of the breakdown of microbial cells.

Suppose you are faced with a problem such as low body temperature. What to do in these situations? First of all, for this there are specialists who will determine the root cause, so a visit to the doctor is required. If the result of a decrease is overwork, it is caused by stress or severe overload, then what to do at a low temperature becomes clear. The advice in this case is simple:

• refuse additional loads;
• provide the body with complete, deep sleep;
• Avoiding stressful situations is a great way to return your temperature to normal.

Don’t panic if you have what to do in such circumstances, we will tell you. The best recipe, which allows you to help your body is a herbal tincture consisting of valerian root and motherwort, prepared in a ratio of 1 tbsp. valerian and 1 tbsp. motherwort, filled with 2 tbsp. boiling water Let it sit for 10-12 hours, then strain and consume in small portions. You can replace the dry mixture with a tincture of the same herbs.

If the low temperature is caused by a serious illness, then the functions of the body in this case can be extremely depleted. The nervous system suffers the most. In particular, the center responsible for thermoregulation is the hypothalamus.

It is recommended to keep drugs used to regulate temperature processes for some time before swallowing. oral cavity, the absorption of substances occurs much more efficiently. Be sure to include vitamins C and E in your diet for one month.

Do you or your loved ones need to provide additional assistance to the body? There are several preparations of animal origin, which include antlers (non-ossified deer antlers). These are cigapan and pantocrine, which will quickly restore impaired function. Aralia and Eleutherococcus are very effective; they are also called adaptogens. 20 drops are dissolved in water and taken 3 times a day for a month.

• In the morning - ginseng tincture.
• At lunchtime we will repeat the adaptogen intake. During meals - vitamins.
• Dinner - motherwort with valerian.

Temperature from birth is one of the main signs of human health or, on the contrary, ill health. Almost everyone knows about the causes of fever, and the ways to eliminate this symptom are no secret. Reduced temperatures are usually not given special attention, although very often it is a low temperature that is a signal of illness or simply a deplorable state of the body.

Normal body temperature is 36.6 degrees Celsius; a temperature of 35.5 degrees or lower is considered low.

Reasons for the “drop” in body temperature

The most obvious reason for a drop in temperature is hypothermia.

This is exactly the case when, to solve a problem, it is enough to change the conditions in which a person finds himself in order for the situation to change. The only danger is prolonged hypothermia, which can lead to irreversible consequences for the body.

Very often, a low temperature indicates serious fatigue or stress. Such changes in the usual way of life invariably affect the body; if stress or overwork is strong enough or lasts long enough, the consequences for the body are inevitable. If this is the reason for the decrease in temperature, the most successful recommendation would be quiet, fairly long and regular sleep, a variety of techniques to relieve stress - from breathing exercises to drugs with a mild calming effect (for example, motherwort or valerian).

If symptoms persist, you will need to consult a doctor. The reasons for a decrease in body temperature below an acceptable threshold may be more serious.

These reasons include:

• exacerbation of chronic diseases
• thyroid dysfunction
• adrenal diseases

Sometimes pregnancy can trigger a low temperature. However, remember that a temperature of 35 degrees can cause loss of consciousness. In such a situation, it is necessary to consult a doctor immediately

Exacerbation of chronic diseases. Any chronic disease has a negative impact on the functioning of the body as a whole; during periods of exacerbation, chronic diseases provoke serious stress for the body. The optimal solution to the problem in this case is to be vigilant about your health and follow the instructions of your doctor, which will minimize the likelihood of an exacerbation. If it was not possible to avoid an exacerbation, it is important to consult a doctor in a timely manner, making sure to inform him of all existing symptoms, including low temperature.

Reduced function of the thyroid gland, which, in turn, provokes hormonal imbalances and dysfunction in the functioning of internal organs.

Ignoring abnormalities in the thyroid gland for a long time can lead to the development of serious diseases, so low temperature must be treated with special attention

If the temperature does not rise for a sufficiently long time and there are no other obvious reasons for its decrease, you should consult a doctor to check the condition of the thyroid gland and further treatment.

Exacerbation of adrenal diseases. It must be removed strictly under the supervision of a doctor, but it is quite possible to avoid exacerbation on your own. To do this, it is enough to drink enough water, choose the appropriate diet, for example, it is recommended to eat melons and watermelons, which stimulate the functions of the adrenal glands and cleanse the body.

Another reason for a decrease in body temperature may be unreasonable self-medication. When using drugs without a doctor's prescription or if the dosage is not correct, the body may react differently to the drug, including a decrease in temperature. It is extremely important to avoid self-medication; all medications taken must be taken strictly as prescribed by the doctor and in the dosage recommended by him.

If, as a result of self-medication, the condition worsens, and the temperature does not rise to normal for a long time, you must consult a doctor to prescribe a suitable solution, and, if necessary, cleanse the body

In young children, low body temperature may be a symptom of stress or fatigue. Also, a decrease is often a symptom of a change in the biochemical composition of the blood; this process is age-related and should not cause alarm, but the pediatrician still needs to be notified.

Thus, whatever the reasons for a drop in body temperature below the normal threshold, in all cases they are very serious and require consultation with a doctor, and sometimes very serious treatment. Downward fluctuations in temperature must be taken as seriously as sudden increases in temperature.

Body temperature is an indicator of human health, which depends on metabolic rate and thermoregulation processes. Normal indicators body temperatures can fluctuate between 36-36.9 degrees, ideal numbers correspond to 36.6 degrees. In medical practice, an increase in temperature (hyperthermia) is more common due to overheating, infections, inflammation and oncology. A decrease in body temperature below 36 degrees usually indicates pathological processes in the body. The thermometer readings in an adult at 35.5-36 degrees in some cases relate to individual characteristics of thermoregulation and do not have a negative impact on health. To understand the causes of hypothermia, you need to see a doctor.

Physiological hypothermia

More than 99% of people have a normal temperature of 36.6 degrees. During the day, under the influence of hormones endocrine system And external factors the intensity of thermoregulation changes. This affects daily temperature fluctuations of several tenths of a degree. Normal biological rhythms are associated with lower thermometer readings in morning hours(36-36.4), in the evening the temperature may rise (36.7-36.9).

In hot climates, body temperature is periodically higher than the average statistical norm, which is associated with overheating, and in cold climates the values ​​are lower due to the high risk of hypothermia. Changes in body temperature are episodic in nature and are processes of adaptation of the body to environmental conditions.

Less than 1% of people are prone to hypothermia due to the individual characteristics of the thermoregulation center in the brain. Typically, the thermometer readings in such patients are at the level of 35.5-36.0 degrees daily, occasionally rising to normal. In the case of infectious and inflammatory diseases, hyperthermia develops with lower fever numbers than in ordinary patients. The tendency to physiological hypothermia does not cause a disorder general condition and performance. During examination, they are not detected in the body pathological changes, which could cause a decrease in temperature.

Pathological hypothermia

Body temperature readings below the average statistical norm in most clinical cases are signs of the disease. With hypothermia, the rate of metabolic reactions decreases and heat transfer worsens, which leads to disruption of the body's functioning. The causes of hypothermia may be associated with diseases of the hematopoietic, digestive, endocrine and nervous system, occur when taking medicines. A decrease in temperature is a symptom of illness. In addition to hypothermia, other Clinical signs illness, which helps determine the cause of the pathology.

Anemia

More common Iron-deficiency anemia, associated with a lack of hemoglobin in the blood and a decrease in the number of red blood cells. Hemoglobin contains iron, which attaches oxygen molecules. Once in the tissue, oxygen participates in the processes of tissue respiration. With a lack of iron, oxygen deficiency occurs (hypoxia), including in the brain, which leads to a decrease in temperature.

Symptoms of anemia:

• dizziness;
• fainting;
• pale skin, blueness of fingertips;
• flashing “flies” before the eyes;
• dyspnea;
• interruptions in the heart area;
• fast fatiguability.

In a general clinical blood test, the number of red blood cells is less than 3.7-4.7X10*12/l, hemoglobin is below 100 g/l.

Liver diseases

Hepatitis, hepatosis, cirrhosis of the liver, occurring with signs of liver failure, cause a violation of thermoregulation. The liver stores carbohydrates in the form of glycogen. They are used by the body to generate heat and maintain normal body temperature. Impaired organ function leads to insufficient glycogen accumulation and hypothermia.

Symptoms of liver failure:

• decreased appetite;
• nausea, sometimes vomiting;
• weight loss;
• lethargy, drowsiness, memory loss;
• yellowness of the skin and sclera of the eyes;
• discoloration of stool.

To diagnose the disease it is prescribed biochemical analysis blood and ultrasound of the abdominal organs.

Starvation

Poor nutrition leads to hypothermia. Extreme diet violations - fasting, vegetarianism, strict diets to reduce body weight. The body does not receive the required amount of nutrients that can ensure normal thermoregulation. A deficiency of fats and carbohydrates leads to insufficient heat generation, and a decrease in the subcutaneous fat layer causes chilliness.

Symptoms of eating disorders:

• unstable stool;
• rapid weight loss;
• dry skin, brittle nails, hair loss;
• angular stomatitis (jams);
• weakness, decreased performance;
• thirst.

Normalizing the daily diet leads to an improvement in general condition and normalization of body temperature.

Endocrine pathology

Hypothermia occurs when the thyroid gland is underactive - hypothyroidism. Thyroid hormones are involved in metabolism and regulate thermoregulation processes. Lack of hormones in the body reduces metabolism and heat production.

Symptoms of hypothyroidism:

• swelling;
• chilliness;
• weight gain with loss of appetite;
• lethargy, drowsiness;
• tendency to constipation;
• dry skin, hair loss;
• memory impairment;
• infertility.

Diabetes mellitus occurs with impaired metabolism and oxidation of glucose. This leads to energy deficiency in the body.

Symptoms of diabetes:

• thirst;
• frequent urination;
• dry mouth;
• tingling and numbness of the limbs;
• increased appetite due to weight loss.

To diagnose the disease, it is necessary to undergo a laboratory examination to determine thyroid hormones and blood sugar levels.

Nervous system diseases

Hypothermia accompanies diseases of the nervous system that occur after traumatic brain injury and spinal injury. Often a decrease in body temperature occurs with neurocirculatory dystonia (NCD) of the hypotonic type. Changes in autonomic innervation lead to disruption of the thermoregulation center and persistent hypothermia.

Symptoms of hypotonic type NCD:

• low arterial pressure;
• weather dependence;
• fast fatiguability;
• pale skin;
• chilliness of hands and feet;
• irritability, emotional instability.

Treatment of the etiological disease helps normalize body temperature.

Oncology

Brain tumors in the hypothalamus region lead to hypothermia. A decrease in body temperature is one of the first symptoms of the disease. The thermoregulation center is located in the hypothalamus. Compression of the brain by the proliferation of tumor tissue causes a disruption in the processes of heat formation in the body.

Symptoms of a hypothalamic tumor:

• uncontrollable thirst;
• long sleep;
• predominance of negative emotions;
• mental instability;
• epileptic seizures;
• obesity, diabetes.

Diagnosis of the disease is carried out using instrumental examination methods ( CT scan, magnetic resonance imaging) and laboratory tests.

Taking medications

Long-term use medicinal substances or failure to comply with the prescribed dosage of the drug leads to a decrease in body temperature. Hypothermia develops with an overdose of antipyretic drugs, sedatives from the group of barbiturates and benzodiazepines, and narcotic painkillers.

If there is a persistent decrease in body temperature for 5-7 days or more, you should consult a general practitioner. The doctor will conduct the necessary diagnostic examinations and write out a referral for consultation with specialists. Hypothermia can be a sign of serious illnesses that impair quality of life and reduce life expectancy.

Body temperature– this is a dynamic value that, within normal limits, can fluctuate during the day, changing by several degrees. In the morning, when the body is just waking up, body temperature is significantly reduced and approximately equal to 35.5 degrees. During the day, the values ​​increase, and in the evening, due to fatigue and decreased activity, the values ​​tend to decrease again. Based on this, it can be noted that the temperature, which is not considered a pathological phenomenon, ranges from 35 to 37 degrees.

The term low temperature- this value of the thermometer is 0.5-1.5 degrees below the accepted norm in the current situation, but not less than 35 degrees.

Low temperature or hypothermia– this is a drop in temperature below the limit of 35 degrees.

Symptoms of hypothermia

When it comes to symptoms, it should be noted that a change in thermoregulation values ​​is a sign of the presence of some kind of disorder in the body. Low temperature in medical practice is considered not as an independent illness, but as a symptom that describes a specific phenomenon. However, if you consider low temperature in isolation from other biological processes occurring in the human body, then you can identify a number of criteria that suggest a decrease in body temperature.

Quite often, along with hypothermia, the following is observed:

• headache;
• circulatory disorders and, as a result, arrhythmia;
• the appearance of dizziness;
• numbness in fingers and toes;
• chills;
• feeling cold;
• trembling throughout the body, accompanied by weakness and loss of appetite;
• nausea and vomiting, but these symptoms do not always occur.

In addition to everything described above, the main criteria that characterize low temperature as a pathological phenomenon should be indicated. First of all, the temperature should drop below 35 degrees and remain static throughout the day. If the situation remains unchanged for several days, it can be argued that there is a serious disruption in the functioning of the body.

Main causes of low body temperature

There can be a lot of causes of hypothermia, and therefore they are divided into a decrease in temperature due to exacerbation of chronic or development acute illness, as well as as a result of local organismal changes. About diseases as a cause of development pathological process We will discuss this in the next paragraph; first of all, we will reveal the essence of the less complex reasons that determine the development of the described problem.

1. Wrong lifestyle, including daily routine and diet, is the main reason for the decrease in body temperature below 35 degrees. In situations where the body does not rest for an insufficient amount of time, while constantly encountering physical and mental overload, the internal energy reserve is exhausted. In this case, low temperature is the least that can arise as a result of working without proper rest.
2. Lack of vitamins. According to statistics, 80 percent of all cases of long-term hypothermia, both in adults and children, are associated with improper diet and nutrition. If the body does not receive all the necessary vitamins, acids and other components with food, then a significant loss of energy potential may begin, characterized by the inability of biological systems to heat the body to normal levels.
3. Severe stress. In fact, all the diseases that people suffer from are the result of suffering from neuropsychic tension and stress. It is stress that forces the body to function differently, accelerating biological processes and directing all available resources to maintain a state of rest, blocking irritating factors. Low temperature in this situation is a fairly common occurrence and means that the body is very weakened.
4. Pregnancy. Temperature during pregnancy tends to rise or fall from time to time and depending on the situation. There is nothing particularly terrible about this, but only as long as the indicators do not go beyond the permissible limits. In such a situation, risks arise both for the health of the mother and for the unborn baby. To prevent everything undesirable consequences It is necessary to monitor your own condition extremely carefully throughout pregnancy. Sometimes hypothermia during pregnancy can be evidence early toxicosis or be a sign of fatigue. More serious causes of the described phenomenon are also possible, for example, endocrine system disorders. Often a specific reaction of the body is accompanied by nausea and dizziness, which can go away on their own without additional influences.
5. Medicines lower the temperature. Some medications can have a negative effect on the body, inhibiting the functioning of systems, as well as disrupting the natural processes of thermoregulation. There are common cases in which the body temperature dropped below normal after taking antibiotics. This happens mainly due to the individual characteristics of the body and its reaction to a particular drug. This phenomenon is similar to the allergic process, in which the immune system due to a genetic disorder, it blocks harmless elements, recognizing them as a threat. To minimize the risks of hypothermia, you should take all pharmacological agents only after a doctor's prescription.

Possible diseases at temperatures below 36 degrees

If no obvious signs If there is no significant decrease in body temperature, then this is a serious reason to think about your own health. In such a situation, most likely, there is the presence of some chronic illness that is in a state of relapse. Therefore, it is necessary to go through the full medical examination by contacting a specialist for a diagnosis. The situation described may be the profile of a large number of specialists, including a neurologist, oncologist, gastroenterologist, endocrinologist or immunologist.

• Oncological diseases. As part of the description of hypothermia as a result of the progression of the disease process, it should be noted that the lion's share of all cases is occupied by oncological diseases. It is the growth of a tumor, such as the brain, that can lead to functional disorders central nervous system, which will cause changes in the process of thermoregulation. Quite often there is a decrease in temperature due to pathologies of the endocrine system, anorexia, poisoning, and HIV.
• Flu. Temperatures can fluctuate greatly with the flu, as the immune system strives to create a disease that is as unfavorable as possible for infection. With this disease, auxiliary symptoms often occur in the form of a runny nose and sore throat. In the described situation, the manifestations of the disease cannot be ignored; it is necessary to immediately begin adequate therapy.
• Cold. Despite the fact that a completely natural condition for a cold is a temperature above 37 degrees, which is designed to destroy the source of the disease, hypothermia also occurs. This can happen in some cases, for example, if a cold arises from an existing, untreated disease. In this case, the fragile body will send all remaining resources to fight the source of inflammation, which under certain circumstances can deplete the immune system. It is for this reason that symptoms such as chills, sweating and cough most often appear against a background of low temperature. Considering such a phenomenon as acute respiratory disease, it should be noted that with this disease local intoxication of the body occurs. Often, toxins penetrate the brain and affect the hypothalamus, which is responsible for thermoregulation. As a result, the body reacts to the virus in a similar way, temporarily reducing the temperature to a minimum. In this case, you need to very carefully monitor the dynamics of the disease, being under constant medical supervision.
• Arterial hypotension. Reduced blood pressure by more than 20 percent of normal is quite common in combination with low body temperature. This happens due to the fact that blood flow slows down significantly, as a result of which cellular respiration and biochemical processes within the body begin to proceed more slowly. The whole point is that the body goes into an energy-saving mode, saving energy. Often a similar process is observed in people in hot weather, as a result of which blood vessels expand, therefore, their area increases, which is one of the tools for reducing body temperature naturally.

Is it dangerous?

A low temperature is only dangerous when it crosses the 35 degree mark on the thermometer. In this case, the phenomenon is already regarded as pathological, and additional measures are required to normalize the readings. In most cases, in order to restore the temperature you need to start eating right and healthy image life, enough rest and sleep.

What to do at low temperatures

Low temperature is a polyetiological condition, so before taking any measures you need to consult a doctor and make sure that this is not a pathological phenomenon accompanying the disease. You can eliminate the decrease in temperature using the following methods:

1. take a few days off. The problem is caused by overwork and a busy schedule, and proper rest is important for recovery;
2. regular consumption of liver, red meat, fresh juices, spices (cinnamon, cloves and peppers). Fatty chicken broths, peanuts and chocolate help cope with low temperatures;
3. adherence to diet;
4. in case of hypothermia, emphasis should be placed on drinking large amounts of hot drinks, taking a bath and resting under a warm blanket;
5. the doctor may prescribe immunostimulating drugs to combat the problem (Pantocrine, Normoxan, vitamin E);
6. It is recommended to take herbal decoctions of St. John's wort, mint, echinacea, and lemon balm.

How to increase the temperature at home

For moderate and mild hypothermia, when the temperature does not cross the lower limit of 31 degrees, medications are not required. There are ways to urgently raise the temperature, but they do not eliminate the problem, but only temporarily relieve it:

1. lubricate the nostrils with domestic stationery glue;
2. eat a couple of tablespoons of instant coffee in dry form;
3. rub your armpits with garlic or salt;
4. eat the stylus a simple pencil and wash it down with water;
5. a few drops of iodine are dripped onto a spoon with sugar or a piece of bread and eaten;
6. activate blood circulation through exercise;
7. procedures are used to increase body heat:
