What causes a person to have a low temperature? What does low body temperature mean? Acute adrenal insufficiency

Loss of consciousness is a condition caused by transient dysfunction of cerebral blood flow, causing tissue hypoxia. It manifests itself as a person’s loss of awareness of reality, loss of reflexes, lack of response to external stimulation (deafening sounds, pinching, patting the cheeks), and depression of the ganglion nervous system. The condition being examined is often a sign of various pathologies or may accompany individual ailments. There are many reasons for the disappearance of consciousness.

Sudden loss of consciousness is characterized by neurogenic etiology (epilepsy or stroke) or somatogenic (hypoglycemia, cardiac dysfunction) genesis. In addition, it can be short-lived or persistent.

Causes of loss of consciousness

- orthostatic, manifested by sudden adoption of a vertical position, taking certain pharmacopoeial drugs;

- occur due to increased susceptibility of the carotid sinus;

- appear due to compression inside the breasts (appears with frequent night urination, coughing, bowel movements).

Hyperventilation fainting occurs due to a feeling of fear and anxiety. Its mechanism is due to an uncontrolled increase and deepening of breathing.

Below are typical signs and symptoms of loss of consciousness. Before falling into an unconscious state, the individual often feels an attack of lightheadedness, nausea, a veil appears, spots appear before the eyes, the subject hears a ringing sound, sudden weakness sets in, and occasionally yawning. Limbs may also become weak and there may be a feeling of impending fainting.

The characteristic symptoms of the described condition include: cold sweat, dullness of the skin, although some individuals may still have a slight blush. After falling into an insensitive state, the individual’s epidermis acquires an ashy hue, the frequency of myocardial contractions can either increase or decrease, the pulse is characterized by a slight fullness, and muscle tone is reduced. While the individual is in a faint state, his pupils are dilated and react slowly to light. Reflexes are often weak or absent altogether. Symptoms of short-term loss of consciousness persist for no more than two seconds.

Prolonged loss of consciousness is characterized by unconsciousness lasting more than five minutes. This condition is often accompanied by convulsions and involuntary urination.

Typically, doctors distinguish three phases of loss of consciousness: pre-fainting, immediate fainting, and post-fainting.

The condition preceding the loss of consciousness is characterized by the appearance of precursors. This state lasts up to twenty seconds. It is manifested by the following symptoms: nausea, lack of air, severe dizziness, weakness, a feeling of heaviness in the lower extremities, pallor of the dermis, cold sweat, numbness of the extremities, decreased breathing, weak pulse, drop in pressure, darkening and the appearance of “floaters” in the eyes, gray skin covers, patients may feel a ringing sound. In some patients, along with the symptoms being analyzed, there is also anxiety or a feeling of fear, rapid heartbeat, yawning, a feeling like a lump in the throat, numbness of the tip of the tongue, fingers, lips. Often, loss of consciousness never occurs, and the attack ends with the listed symptoms. Especially when taken by the patient immediately after the appearance of the first harbinger of a horizontal position. Very rarely, a fainting state is characterized by suddenness, in other words, it occurs in the absence of previous warning signs. For example, with various myocardial rhythm disorders. The feeling of loss of consciousness and “floating away from under the feet of the earth” is the final sign of the phase in question.

The immediate stage of fainting has the following signs of loss of consciousness: unconsciousness, shallow breathing, decreased muscle tone, weakness of neurological reflexes, and sometimes convulsions. Pupils are dilated, response to light is reduced. The pulse is quite weak or not palpable at all.

While in an insensitive state, the epidermis becomes pale, ashy or greenish, the limbs are cold to the touch, the pressure decreases (systolic pressure reaches 60 mm Hg and below), the pupils are dilated, they react poorly to light, breathing becomes shallow (sometimes it seems that the person is not breathing at all), the pulse is rather weak, thread-like, and reflexes are reduced. If after twenty seconds blood circulation in the brain is not restored, involuntary urination and defecation may occur, and convulsions are also possible.

The postfainting stage is characterized by the persistence of general weakness against the background of the return of consciousness. In this case, a sudden adoption of a horizontal position can give rise to a new attack.

After the complete return of consciousness, patients have no disorientation in time, self and space. The first reaction to fainting is fear. Therefore, breathing and heart contractions increase. People feel tired, exhausted, and often experience unpleasant sensations in the epigastric region. People do not remember the middle phase of the insensitive state. Their last memories relate to the first stage, that is, deterioration in health.

Brief loss of consciousness

A sudden fall into an insensitive state always provokes stress in people, since their brain associates the phenomenon in question with a life-threatening disorder or with imminent death. Loss of consciousness mainly occurs due to O2 deficiency in brain tissue. Since this organ has a fairly intense metabolic metabolism and the need to consume huge amounts of oxygen, a slight decrease in oxygen content causes disturbances in consciousness.

The brain regulates the functioning of the body. He can also turn off organs that he currently considers unimportant for the life of the body, and help vital organs, such as the heart. By turning off consciousness, the brain seems to switch off individual oxygen consumers from the chain to reduce the body’s energy consumption. The consequence of this is muscle weakness, dizziness and loss of consciousness, in which the body assumes a horizontal position and becomes completely immobile, which allows the body to direct blood flow to the neurons of the brain. As a result of this mechanism, the individual quickly returns to consciousness.

Short-term loss of consciousness can be neurogenic, somatogenic and extreme.

In turn, neurogenic syncope is caused by various factors and is divided into the following types, namely reflex syncope, emotiogenic, associative, dyscirculatory, maladaptive.

Reflex fainting is provoked by an increase in the tension of the parasympathetic nervous system, a drop in pressure due to the rapid expansion of capillaries, which reduces the blood supply to the brain tissue. This type of fainting occurs predominantly in a standing position. Reflex unconsciousness can occur due to exposure to stressors, a sudden sensation of pain (more often in young people). In addition, the considered variation of the fainting state often occurs during rapid movement from a horizontal position to a vertical torso of a person, during a long-term stay in a horizontal position, defecation, urination, during eating (mainly in elderly people).

Emotionogenic loss of consciousness occurs due to a sharp emotional outburst, fear. More often observed in neurotic conditions. Often, in emotionally unstable people, against the background of a frightening event, heart palpitations, a feeling of heat and difficulty breathing appear. There may also be a feeling of losing consciousness.

Associative syncope occurs when the subject has memories of past pathogenic situations associated with loss of consciousness.

Dyscirculatory unconsciousness is caused by a transient spasm of the brain capillaries, which deprives a certain segment of the brain of oxygen for a short period. The most commonly described type of insensible state is found in subjects suffering from vascular dystonia, migraines, and hypertensive crisis.

Maladaptive loss of consciousness occurs when an individual is in a hot room, in an environment with low or high oxygen content.

Cardiogenic syncope occurs due to cardiac pathology, for example, valve disease, insufficient blood output, arrhythmias.

Sudden loss of consciousness of a somatogenic nature is associated with dysfunction of certain organs. Therefore, it can be of cardiogenic origin, hypoglycemic, anemic and respiratory.

Anemic fainting occurs as a consequence of significant blood loss, in particular, quantitative loss of red blood cells, which are the main carriers of O2.

Hypoglycemic unconsciousness occurs in a situation of sudden rapid decrease in blood sugar, which is the main nutrient of the brain.

Respiratory syncope is caused by a disorder of the respiratory system.

Weakness and loss of consciousness of extreme origin occurs due to the influence of various external factors. It happens:

- intoxication, when inhaling various toxic gases;

- medicinal, due to the use of pharmacopoeial drugs that reduce capillary tone;

- hyperbaric, due to high pressure in the respiratory system due to increased atmospheric pressure;

Fainting and loss of consciousness, what is the difference

Both of these phenomena are not uncommon, but it is quite difficult for an untrained person to determine whether an individual has fainted or lost consciousness. The average person does not have the proper knowledge, and therefore cannot notice the difference between fainting and loss of consciousness.

So, fainting is a sudden, short-term loss of reason that occurs due to a transient insufficiency of the capillaries of the brain. In other words, the brain feels a lack of oxygen due to poor blood flow. The described condition occurs as a result of sudden oxygen starvation. It is accompanied by suppression of reflexes, a decrease in the frequency of myocardial contractions, and a decrease in pressure.

Loss of consciousness is a long-term disorder in which there is a lack of reflexes and depression of the ganglionic nervous system. The violation in question is dangerous due to the possibility of transition into a coma.

Below are the main characteristics of loss of consciousness and fainting.

Absolutely all individuals can fall into a state of syncope or fainting, regardless of their differences in age, gender and physical condition. Short-term fainting often occurs when frightened, in a stuffy room due to lack of air, during menstruation, during pregnancy, with a sudden decrease in blood pressure, due to an overdose of drugs or abuse of alcohol-containing liquids, with excessive physical exertion, fasting or poor diet. Each of these factors provokes an outflow of blood from brain tissue, which causes short-term oxygen starvation of neurons.

The main signs of syncope (fainting) are the following: slight confusion of mind, noise in the ears, yawning, dizziness, cold extremities, pale or cyanotic dermis, profuse sweating, decreased muscle tension, nausea, decreased pressure, unpleasant sensation in the mouth, dilated pupils . Fainting looks from the outside as if a person is gradually sinking to the floor. Blackout does not occur instantly and can last up to 120 seconds.

Loss of consciousness is a prolonged syncope that occurs due to severe oxygen deficiency in brain cells.

Among the factors that give rise to the disorder in question, the following are distinguished: disruption of blood flow through the capillaries caused by thrombosis, arrhythmia, narrowing of the lumen of the blood capillaries, embolism, venous stagnation, insufficiency of cardiac output, decreased sugar concentration, insulin overdose, epilepsy, concussion, pathologies of the nervous system, chronic diseases of the pulmonary system, osteochondrosis of the cervical segment, intoxication of the body with various toxic agents, such as nicotine, carbon monoxide, alcohol-containing substances.

In an unconscious state, the individual lies motionless. He has no reactions to external stimuli, the muscles of the body are relaxed, which is why involuntary urination or defecation is possible, and the light sensitivity of the pupils is reduced. There is also cyanosis of the skin and cyanosis of the nails due to impaired breathing and oxygen deficiency.

First aid for loss of consciousness

Having noticed that the individual is losing consciousness, first of all, it is recommended to provide first aid and take actions to prevent the occurrence of bruises and head injuries. Then the etiological factor of syncope should be eliminated. For example, if an individual passes out due to heat, then it is necessary to reduce the temperature in the room by opening the windows. You can try to return the person to consciousness through external stimuli (sprinkling the face with cold water, patting the cheeks, irritating with ammonia).

Loss of consciousness first aid should avoid commotion and unnecessary fuss. will only make the situation worse.

If an individual has ordinary fainting, then eliminating the factor that gave rise to such a condition will quickly return the person to sanity. In a faint state, loss of consciousness occurs due to a disruption in the blood supply to the brain. Therefore, restoring normal blood circulation is the main task of people providing assistance. In order to return the blood flow to normal, it is necessary to lay the victim down. In this case, his body should be placed at the same level as his head. This means that, contrary to popular belief among ordinary people, there is no need to put anything under your head, and even more so, you should not throw it back. Since vascular tone is reduced, raising the head will lead to an outflow of blood from the brain cells and restoration of blood supply to the brain will not occur.

Providing assistance in case of loss of consciousness is usually not much different from measures to bring a person out of fainting. The patient must be removed from the area of ​​exposure to damaging factors, his clothes must be unbuttoned to provide air access, he must be laid horizontally, shaking or trying to lift the patient is not recommended. If nosebleeds occur, the individual should be placed on his side. It is impossible to give water to a person who is unconscious, since his reflexes, including swallowing, are absent. The patient may choke if you try to force him to drink. If the individual has not regained consciousness after one hundred and twenty seconds, then he must be hospitalized.

Fainting rarely occurs suddenly. It often follows presyncope symptoms, which include rapidly increasing nausea, dizziness, tinnitus and blurred vision. All of the above is observed against the background of general weakness. Sometimes yawning and sweating may occur. The human epidermis acquires a waxy pallor. After which muscle relaxation is noted, the individual switches off and settles down. From the moment of discovering the first signs of poor health to the fall, most often, no more than sixty seconds pass. Therefore, first aid for loss of consciousness should begin immediately after the appearance of the onset precursors. After all, often the etiological factor is unknown.

It is impossible for an individual who has regained consciousness to independently administer medications, in particular, nitroglycerin for complaints of cardiac algia. Since such actions can cause a drop in pressure, which will cause repeated fainting. Often, loss of consciousness occurs against the background of a sharp drop in pressure, during which any nitrate-containing substances are completely contraindicated.

Loss of consciousness is considered a rather threatening symptom, indicating the presence of a serious pathology in the body. Therefore, assistance in case of loss of consciousness should be provided immediately. A person assisting in a loss of consciousness does not have time to panic. After all, any delay often carries a serious threat to the life of the victim.

Diagnosing loss of consciousness is not difficult. It is enough just to note the presence of such phenomena as lack of response to external stimuli, including pain, complete immobility, excluding convulsions. However, determining the etiological factor is often difficult.

In order to facilitate the task of diagnosing syncope, doctors use all research methods known to modern science. The diagnostic process begins with a study of the anamnesis, which allows us to identify the presence of pathologies that can cause loss of consciousness, determine the use of pharmacopoeial drugs that lower blood pressure or affect the functioning of the nervous system, and, if possible, determine the provoking phenomenon, for example, physical overexertion, rapid rise from a lying position , being in a stuffy room, heat.

From laboratory tests, first of all, blood is drawn:

- to conduct a general analysis to identify the presence of anemia;

- to determine the concentration of glucose (this analysis allows you to determine the presence of hyper- or hypoglycemia);

- to identify indicators of blood O2 saturation (helps to identify disorders that interfere with normal oxygenation).

Various instrumental studies are also carried out:

- electrocardiogram, which allows you to determine the presence of heart blockades and arrhythmias;

- a type of electrocardiogram - daily monitoring of myocardial rhythm;

- ultrasound examination of the heart muscle, which helps to detect changes in cardiac contractility of the heart and determine the condition of the valves;

- Dopplerography of the carotid capillaries, which helps to establish barriers to blood flow;

- computed tomography to detect brain pathologies;

- magnetic resonance imaging aimed at identifying damaged segments of brain tissue.

In order not to encounter the disorder in question in life, it is necessary to take preventive measures.

To prevent syncope, the ideal solution is regular exercise, which optimizes natural blood circulation and strengthens blood capillaries. It must be taken into account that any stress on the body, first of all, must be regulated and moderate. There is no need to try to break Olympic records in the first lesson. The main thing here is systematicity, not intensity. In addition, an evening promenade will not only minimize the risk of loss of consciousness, but will also increase the body’s overall resistance to various ailments and stress.

Aromatherapy also occupies an important position in the list of preventive measures. Regular aromatherapy helps relieve convulsions, spasms, improve blood circulation, and saturate the blood with O2.

In addition to the listed preventive measures, there are measures aimed at avoiding fainting when you feel the warning signs. If numbness of the limbs, nausea, or cold sweat suddenly appears, then you need to quickly take a lying position, raising your legs up, or sit down, lowering your head below knee level. Then you should remove from the neck area any objects that interfere with free breathing (tie, scarf). After relief, it is recommended to drink water or sweet tea.

Every person gets a fever from time to time, and there are a great many reasons for this: from a sudden surge of feelings of love to a common cold. There is nothing surprising or out of the ordinary in this, the situation is completely ordinary. We put in a thermometer, measure body temperature and if it exceeds 38°C, we take antipyretic medications.

But another, diametrically opposite picture is also possible: body temperature is reduced, general weakness, “loss of strength”, drowsiness, and sometimes slight dizziness are felt. Despite the fact that low body temperature is much less common than elevated body temperature, it is imperative to pay serious attention to it. The site will tell you what low body temperature indicates.

What temperature should be considered normal?

A decrease in human body temperature by just a few degrees is quite capable of disrupting the functioning of internal organs and damaging the normal functioning of the body. Moreover, in some cases, even death is possible.

For example, a constant body temperature not higher than 35°C clearly indicates the presence of a serious chronic disease, a decrease to 29.5°C entails loss of consciousness, at 27°C a person can fall into a coma, and a decrease in temperature to 25°C already considered incompatible with life.

Considering that most people have individual characteristics of their body’s functioning, small deviations from generally accepted indicators may not go beyond normal limits. So, if a person does not experience any unpleasant symptoms, does not complain of weakness, feels cheerful and efficient, if the examination does not show any abnormalities, and the body temperature is constantly below generally accepted figures, then this can be considered as some kind of normal.

However, the average normal body temperature is considered to be between 35.5 and 37°C. It should also be taken into account that throughout the day the temperature can vary within 1°C, reaching a peak at 16:00. And in women, in addition to daily fluctuations, there are also temperature changes depending on the menstrual cycle.

What are the reasons for a decrease in body temperature?

Body temperature can drop either as a result of a serious illness, in which case it is necessary to undergo a thorough examination, or for simpler and more understandable reasons: decreased immunity, lack of vitamins, previous infectious diseases, surgical interventions, stress, physical exhaustion.

As a rule, a person who has detected a low temperature does not take any measures to normalize it. This approach is completely unacceptable, especially in cases where a low temperature level is observed for one or two days, and there are no logical explanations for its decrease. It is important to know that to determine the causes of hypothermia and make the correct diagnosis, you must first consult a physician. Since body temperature is only an external manifestation of hidden problems in the body, it is necessary to carefully study the available other symptoms and laboratory test results.

First of all, the general practitioner will refer the patient for an ECG and a biochemical blood test, which will rule out any serious disease and determine the presence of just a temporary illness, as a result of a possible weakened immune system. In this case, it will be enough just to adjust the diet, including vitamins and immune preparations, and change the daily routine, making it more physiological and gentle.

What does low temperature mean?

If the therapist still has reason to suspect the presence of any serious internal disease, the patient must undergo a comprehensive examination, consult with specialized specialists such as an endocrinologist, gastroenterologist, neurologist, and even an oncologist, because the reasons for the decrease in body temperature may lie in the development of certain oncological diseases, for example, brain tumors. Therefore, at the slightest suspicion of oncology, it is necessary to urgently conduct a tomographic examination.

Other causes of decreased body temperature

In addition, low temperature can signal the presence of chronic inflammatory diseases, various endocrine disorders, anorexia, intoxication, and AIDS. In any case, you should never resort to self-medication, because if you uncontrollably take medications not prescribed by a doctor, but chosen independently, the body may not be able to cope with the true cause of the ailment and may fail.

But, fortunately, most often the reason for a decrease in body temperature is just simple fatigue, which is greatly facilitated by the frantic pace of modern life. And even if a person spends his working day sitting at a desk in the office, chronic fatigue can overtake him there too.

What does low temperature mean?

A sedentary lifestyle, constant mental stress, and stiff posture lead to fatigue, and with it a drop in temperature, not to mention such pathologies as varicose veins, osteochondrosis and curvature of the spine. It’s quite easy to correct this situation; you just need to get up, stretch, do a few simple physical exercises, drink tea or coffee, and even treat yourself to a forbidden, completely non-dietary chocolate bar.

Normal human body temperature is 36.5-37.2 degrees Celsius. Low body temperature in an adult is a deviation from the norm, and therefore requires consultation with a doctor. This phenomenon is called hypothermia.

What is the deviation? The point is that body temperature is an indicator of the state of the organs responsible for heat exchange and heat production. Therefore, a low temperature indicates a malfunction of these organs. However, the lowered temperature is accompanied by a change in state. And if it does not happen, a lower body temperature for most people may be normal for an individual - such exceptions also occur and no measures are required.

Symptoms

• low blood pressure and pulse;
• irritability appears;
• drowsiness, lethargy;
• your head begins to feel dizzy, “speckles” flash before your eyes;
• the skin becomes pale and cold to the touch, the person trembles;
• weakness, loss of strength, sluggish movements and, ultimately, general malaise.

A low temperature is no less scary than an increased one, and if the above symptoms turn into hallucinations, speech becomes slurred, movements become clumsy, paralysis is possible, the skin turns from pale to gray and subsequently blue, the temperature already becomes abnormally low, at which a person loses consciousness and then death comes.

Reasons that can lead to low temperature

1. First of all, this is frequent and prolonged exposure to cold air or cold water. All this can provoke hypothermia, and if cases of hypothermia are repeated, this will ultimately lead to a case of low temperature.

Therefore, those who like skiing, hiking, fishing or Nordic walking in winter should refrain from outings in frosts above 30 degrees. And even in moderate cold, staying outside must be dosed incrementally - start with a 10-minute walk, gradually adding time. But at the first sign of freezing, you should return home. Insulate yourself as much as possible and have a sufficient supply of hot food and drink with you when hiking. And for lovers of swimming, keep an eye on the water temperature - it just needs to be tolerably warm. As for winter swimming, you need to get used to it gradually - one dive is enough to start with, then immediately into the warmth.

2. Overwork. It is necessary to rationally alternate work and rest. And not just work and rest, but also favorable conditions for them. You shouldn’t be a hero by harvesting potatoes on a dank, rainy and wildly cold day. It is no coincidence that weather conditions are mentioned in the paragraph on overwork - too cold weather is not only one of the unfavorable working conditions, but also contributes to overwork to an even greater extent.

3. Malnutrition and weak immunity. Followers of diets should take into account that the body must receive the required amount of carbohydrates, vitamins and fats. It is their deficiency that can cause a low temperature. It is necessary not only to eat right, but also to pay attention to the presence of hot dishes in the diet.

4. Poisoning, including low-quality alcohol. Monitor the quality of food consumed, pay attention to expiration dates; Don’t get carried away with alcohol, and if you do take it, it’s good quality.

5. Taking antidepressants, sleeping pills, individual intolerance to certain drugs, drug overdose.

Taking medications is the last thing you can joke with. It is simply VITALLY necessary to carefully read the instructions for medications, take them in strict accordance with the recommendations, and resort to antidepressants and sleeping pills only in exceptional cases.

A low temperature is possible due to diseases or abnormalities that occur in the anamnesis even some time ago;

Reduced body temperature is also possible during recovery from a long illness.

Self-medication is inappropriate here; it will only worsen the situation. In addition, it is impossible to do without the intervention of a specialist because, in addition to a standard examination and measuring the patient’s temperature, studies such as blood pressure measurement, urine, feces and blood tests, X-rays, electrocardiogram, diuresis (hourly), monitoring and pulse oximetry will be needed. All this is prescribed without fail in order to identify the exact cause of the drop in temperature. A reduced number of red blood cells and hemoglobin may indicate that anemia is the cause of the drop in temperature.

Discolored stool indicates that the cause is liver disease. This will confirm the assumption if the patient suddenly has a decrease in appetite, coupled with a sharp decrease in weight, yellowish skin and sclera of the eyes, nausea, vomiting, a constant desire to sleep, and there is also a sudden deterioration in memory. In this case, to clarify the full picture, a biochemical blood test and ultrasound of the abdominal cavity will be prescribed.

If the stool is simply unstable (both hard and liquid, or simply irregular), then the cause may be poor nutrition or fasting.

Pathologies of the thyroid gland are perhaps the first thing after frequent exposure to cold air that can cause insufficient body temperature - after all, both excess and deficiency of hormones can disrupt metabolism, and, as a result, thermoregulatory processes.

The most obvious sign that it’s all about the thyroid gland is weight gain in the absence of appetite or, on the contrary, sudden weight loss with a voracious appetite (Graves’ disease). Constant thirst, dry mouth and intense and frequent urination indicate that the source of the disease is diabetes. In this case, at low temperatures, alternating numbness and tingling of the arms and legs is possible. This will not do without tests for hormones and blood sugar levels.

Nervous diseases in this regard are dangerous if there is low blood pressure, weather dependence, unreasonable aggression and irritability, and constantly cold hands and feet.

To accurately determine what exactly oncology provoked the decrease in temperature, MRI, computed tomography and a number of laboratory tests are necessary. After all, the presence of cancer is not yet a reason to believe that it was they who contributed to the decrease in temperature in general. Although, in principle, the probability is quite high.

First aid

In case of excessive freezing, it is recommended to take a warm bath with herbs or aromatic oils, and then drink hot tea with honey, cover yourself as warmly as possible and get a good night's sleep. The portal site draws your attention to the fact that instead of a bath, you can limit yourself to a hot foot bath with the addition of mustard and put on warm socks. If there has been a fall into cold water, then clothes must be removed as quickly as possible, rub the body with an alcohol-containing substance, wipe dry and change into dry and warm clothes.

If possible and if there are no contraindications, you can go to the bathhouse. Traditional medicine advises rubbing the armpit area with salt. A piece of sugar sprinkled with a small amount of iodine will raise the temperature - you need to eat it. If you are pregnant, it would be a good idea to call an ambulance.

How to increase body temperature in the future?

If the temperature drop is due to malnutrition, excessive dieting, or lack of hemoglobin, it is necessary to replenish its amount and enrich the body with vitamins and minerals. This also includes a decrease in temperature due to low immunity. In all these cases, you need to pay attention to the use of vitamin C - you can take ascorbic acid in tablets, eat more citrus fruits, sauerkraut and other products containing this vitamin. Products such as raisins, prunes, dried apricots, and nuts also regulate heat exchange. It is recommended to drink infusions of valerian, hawthorn, motherwort, ginseng, and ginger root infusion.

For anemia, you need to focus on iron-containing foods: apples, spinach, etc. You should pay attention to active recreation - cycling, outdoor games, running, and Nordic walking are very useful. For sports in the cold season, it is recommended to purchase thermal underwear. After stress, you need to get enough sleep and not succumb to it completely.

And maintaining a daily routine, proper nutrition, work and rest is the key to protection from all ailments, and low temperature is no exception. Even if the necessary measures that a person can take on his own have been taken, a visit to the doctor should never be neglected. If a decrease in temperature has occurred, sooner or later it will happen again. And it’s not a fact that next time the person will get away with a slight fright. The phenomenon is insidious - it can happen in a day or a year. But one thing is clear: such a relapse will most likely entail a pathologically LOW temperature, and these are different measures and a different picture - sometimes a couple of seconds of delay can cost the patient his life. Especially if both the first and second attack are one of the manifestations of a serious illness. Needless to say, if a person has not consulted a doctor, he may simply not know about the disease.

But, unfortunately, this is the psychology of many people - everything turned out okay. No, often this is just the beginning.

Probably each of us knows that the normal body temperature of a healthy person is 36.6 degrees. If it increases, then this indicates a pathological state of the body or the development of a certain disease in it.

Everyone knows what to do when the temperature rises - try to understand its main causes, and then bring it down to normal readings with antipyretic drugs or folk methods.

But there are situations when a person’s body temperature is lowered. What to do in this case and what could be the reasons for this phenomenon? We'll talk about this in this article.

Diseases that can cause hypothermia

Low body temperature in humans (35.5 and below) can provoke certain diseases:

• , flu;
• depression, apathy;
• anorexia, bulimia;
• pathologies of the adrenal glands;
• oncological diseases;
• thyroid diseases;
• pathologies in the functioning of the brain;
• in acute or chronic forms;
• various bases and;
• in a situation of a sharp drop in blood sugar;
• inflammatory and infectious diseases of various origins;
• various variants of internal chronic diseases at the time of their exacerbation.

• state of shock;
• hypothermia;
• chronic lack of sleep;
• fasting and strict diets;
• depletion of the internal forces of the body;
• drinking a lot of alcohol;
• prolonged stress and nervous overstrain.

To know how to eliminate low temperature, you need to find out the reason for its decrease. If during the day the temperature fluctuates between 35.8°C and 37.1°C, this is considered normal. For example, in the morning the indicators are lower than in the evening.

Causes of low human body temperature

If we talk about the reasons for the occurrence of such an unpleasant feeling, in which there is a low body temperature of a person, they are presented below:

1. A fairly common occurrence is a low temperature during pregnancy, but usually this condition goes away quite quickly as the body adapts to a different sleep pattern and replenishes the substances that were spent on feeding the fetus.
2. Diet. Lack of fats and carbohydrates weakens our body. The temperature begins to drop when the body's reserves are running low and are no longer enough for normal life. To maintain normal body temperature, you need to eat well.
3. Uncontrolled taking various medications, including those that depress the central nervous system (sedatives, tranquilizers, antidepressants, barbiturate-based drugs);
4. Loss of strength, lack of iron in your body, that is, anemia. In order to check this, you need to immediately do a general blood test and check your hemoglobin level.
   Often, a decrease in body temperature is accompanied by a disease such as hypothyroidism, which is characterized by functional disorders of the thyroid gland, as well as insufficient production of thyroid hormones.
5. Severe hypothermia. The most dangerous temperature for the body is considered to be an ambient temperature ranging from +10 to -12 degrees. If you stay in such conditions for a long time, hypothermia is possible, which will lead to a decrease in body temperature.
6. A decrease in temperature is typical for people suffering adrenal diseases. This symptom is especially common in Addison's disease, also called adrenal insufficiency.
7. Dehydration- another possible reason for a decrease in body temperature. Everyone knows about the importance of water for human life, but not everyone makes sure that water enters the body in the quantities necessary for quality life.
8. The reasons for this phenomenon may be x chronic diseases, precisely the moment when they progress. This includes vegetative-vascular dystonia.
9. Colds (acute respiratory infections or acute respiratory viral infections), flu. Oddly enough, these diseases can provoke both an increase and a decrease in temperature.
10. A brain tumor, which occurs in the hypothalamus, which is responsible for heat exchange in the body, also causes chills and, as a consequence, a decrease in temperature.

Recently, values ​​from 36.4 °C to 36.7 °C have been considered normal, but normal values ​​for each individual person may differ, and different doctors have different points of view. And it is very important that when determining the “normality of temperature”, not some average statistical figures are taken into account, but indicators that are characteristic of each individual person.

Symptoms

Symptoms that may indicate a low temperature include:

• loss of appetite;
• irritability.
• increased drowsiness;
• apathetic state, general malaise;
• slowness of thought processes;

In a small percentage of people, a decrease in body temperature is the norm, but the person feels well and is completely healthy. But, in most cases, low body temperature indicates possible problems or diseases.

Prevention

To prevent your body temperature from dropping below normal, you need to exercise more often, take more vitamins, and also take care of your body.

Proper nutrition and daily routine will have a very beneficial effect on your body. Try to arrange moments of rest for yourself during the working day, and do not overwork yourself.

If you feel that your body is on the verge, then experts advise to put aside everything and just relax, drink hot tea and get some sleep. During sleep, our body normalizes its work, and the body temperature rises to normal values.

What to do if a person has a low body temperature?

First of all, you need to understand whether a decrease in a person’s temperature is normal or a deviation from it. From the resulting picture it will be more clear what to do in each specific case, as well as what treatment will be needed.

1. If you just take your body temperature and find it has dropped without experiencing any other symptoms, then calm down. Remember if you have recently had ARVI or another infection. Perhaps these are residual effects.
2. Hot tea with the addition of honey or currant leaves helps. If this is not available, you can replace it with raspberry jam.
3. Maybe the reason is the abundant ventilation of the apartment on a frosty day. In this case, you need to close the windows, dress warmly and drink a hot drink.
4. Safe means that allow you to normalize the condition at a low body temperature of 35.5 (and below) degrees are decoctions and tinctures of ginseng, St. John's wort, and echinacea.
5. If, in addition to a low temperature, you feel weak, depressed, or find many other symptoms, then it is better to consult a specialist.

Most likely, after additional tests, anemia or reduced thyroid function will be found. Prescribing appropriate treatment will help raise the temperature.

If, at a low body temperature, a person does not experience any unpleasant symptoms, is alert and able to work, examinations do not reveal any pathology, and the temperature throughout life remains lower than usual for a healthy person, this can be regarded as a variant of the norm.

When the body temperature drops below the permissible limit, it cannot pass unnoticed by a person. Various unpleasant symptoms are added to this condition. Before sounding the alarm and looking for ways to normalize the temperature, it is necessary to determine the root cause that provokes this condition.

Constantly low body temperature in a person - normal or pathological

These features include:

1. age; Elderly people often experience a consistently low temperature due to aging changes in the body;
2. specific features of physiology; often people who have arterial hypertension, but do not experience any unpleasant symptoms and no consequences, also note a constantly low temperature, which can drop to 34.5-35 degrees;
3. body structure; people who are distinguished by a fragile physique and pale skin very often suffer from a constantly low body temperature below 36 degrees; this is combined with weakness of the nervous system and slow metabolic processes occurring in the body;
4. the presence of low body temperature is typical for women who are in an “interesting situation”, as well as during menopause (after 50 years); This is also not considered a pathology and is close to normal; it does not require urgent medical intervention if the woman feels normal and is able to raise her body temperature to the most comfortable level on her own.

It is customary to talk about pathology in the context of low body temperature in a person when, during the examination, negative internal factors that provoke such a condition are discovered. If from birth there was no tendency to have low readings on the thermometer, and hypothermia persists for a long time, this should be a reason to visit the doctor’s office.

• depressed breathing;
• decreased performance of all internal organs and systems;
• slowing down processes occurring in the body;
• severe dizziness and fainting (at a low body temperature of 35 degrees).

In a situation where a person’s body temperature at any age drops below 26 degrees, a coma may develop, which can lead to death if medical assistance is not provided in time.

Why hypothermia occurs: causes of low body temperature in humans

In order to effectively increase low body temperature at home, it is important to determine the main cause that provokes the condition. In some cases, when the underlying cause of hypothermia is an internal imbalance, a medical examination will be required.

1. hypothermia;
2. prolonged and nervous overstrain;
3. depletion of the internal forces of the body;
4. chronic lack of sleep, irregular life schedule;
5. fasting, which provokes loss of strength, as well as extreme diets;
6. state of shock;
7. a large amount of alcohol consumed.

• in a situation of a sharp drop in blood sugar;
• HIV infections;
• , ; usually accompanies a person against their background, but in some cases hypothermia can be the answer to the disease;
• oncological diseases;
• various bases and low hemoglobin;
• depression, apathy;
• vegetative-vascular dystonia;
• pathologies in the functioning of the brain;
• thyroid diseases;
• hormonal imbalance;
• pathologies of the adrenal glands;
• , bulimia;
• bronchitis in acute or chronic forms;
• various options for internal chronic diseases at the time of their exacerbation;
• inflammatory and infectious diseases of various origins.

1. weakened immunity, in particular after a serious illness;
2. poisoning with poisons, toxins, chemicals, drugs, alcohol;
3. low body temperature in an adult or child may occur after a “shock” dose of antipyretic drugs during the period of illness;
4. Hypothermia is typical after surgery;
5. uncontrolled use of various medications, including those that depress the central nervous system (sedatives, tranquilizers, antidepressants, barbiturate-based drugs);
6. lack of vitamins (especially vitamin C) and important microelements in the body;
7. and damage to the skin, stimulating the dilation of blood vessels in the body.

Symptoms of low body temperature

Main symptoms of low body temperature

1. Pre-syncope and fainting.
2. Feeling cold, chills.
3. Paleness of the skin, which may be accompanied by cold sweat.
4. or individual parts of the body, goosebumps.
5. Difficulty focusing your eyes.
6. Feeling of general weakness, fatigue, malaise.
7. You may feel nauseous.
8. Drowsiness.
9. Confusion of thoughts, inability to concentrate on anything.
10. Slowness of all mental processes, as well as speech.
11. You may feel restless, worried, or afraid.
12. Slight trembling of limbs and fingers.

Low body temperature in a child (video)

The reasons that can provoke hypothermia in children are basically the same as in adults.

It is worth noting that low body temperature is typical not only for premature babies, but also for newborns in the first few days of life. A baby who has suffered serious stress at the time of birth is unable to immediately adapt to the environment, so a so-called “cold shock” occurs, due to which the readings on the thermometer can be very low.

In a situation where a significantly reduced body temperature is observed in an infant for a long time, this may indicate:

1. insufficient nutrition and lack of vitamins in the body;
2. imperfection of the thermoregulation mechanism (passes over time);
3. pathologies of brain development, in particular the pituitary gland, as well as head injuries received but not recorded at birth.

Symptoms in a situation of low temperature in a child also usually correspond to the symptoms that are characteristic of adults. But a few more reasons can be added to them.

Additional symptoms of hypothermia in a child:

• moodiness, near tears, and general lethargy;
• poor appetite;
• reluctance to take part in outdoor games;
• apathetic state and bad mood.

How to increase body temperature

The most effective and safe means that allow you to normalize the condition at a low body temperature of 35 (and below) degrees are decoctions and tinctures of ginseng, St. John's wort, and echinacea. Strong green tea with a spoonful of honey, as well as hot black tea with raspberries, have a beneficial effect on changing body temperature and increasing the overall tone of the body. Strong coffee also helps bring body temperature back to normal; you can add a pinch of cinnamon to it.

In a situation where hypothermia occurs due to hypothermia, you should:

1. change into warmer and drier clothes;
2. put a heating pad on your feet;
3. heat the air in the room;
4. you can take a contrast shower, but you should carefully monitor changes in water temperature so as not to cause a sharp jump in blood pressure;
5. provide the person with warm drinks and food.

In moments of hypothermia or low body temperature due to a cold, especially in young children, rubbing should not be done, in particular with alcohol or vinegar. This can cause more harm to your well-being.

Short foot baths help to increase a person’s low body temperature at home. The water should not be too hot, and you can also add a spoonful of mustard powder or a few drops of eucalyptus oil to it for better warming.

In case of prolonged stress, which provokes loss of strength and low temperature, you can use medicinal teas with mint, lemon balm, or use tinctures of valerian, hawthorn, and motherwort. But these methods should be used with caution so as not to cause an even greater loss of strength, drowsiness, or drop in blood pressure.

1. "Pantocrine";
2. "Normoxan".

Rapid temperature rise: extreme methods

It is worth understanding that by resorting to such methods, you may encounter adverse consequences, for example, in the form of poisoning of the body.

1. Pharmacy iodine can increase body temperature. It cannot be consumed in its pure form, so a few drops of the product can be diluted in a glass of water or moistened with an iodine solution on a piece of sugar.
2. Another option: eat a little pencil lead (from a simple pencil), washed down with clean water. There is no need to chew or make powder out of the lead.
3. Rubbing the body, especially the armpits, with pepper, mustard, and garlic powder helps to quickly raise body temperature to 38 degrees or higher.
4. Using methods that increase the temperature, for example, compresses with vodka or vinegar, in a situation where it is impossible for the body to transfer heat (for example, wrapping yourself in several woolen blankets, wearing warm socks soaked in a solution of vinegar or vodka), will achieve the desired result.
