Many people have to experience quite a lot of discomfort due to the fact that they are freezing in winter. Everyone is cold in winter, but for some people the cold season is especially unpleasant. Even when they are decently dressed, they are cold. Why do people freeze in winter? It is not at all easy to answer this question unequivocally.
One could simply say that people are cold because the ambient temperature is low, but some can.
What is responsible for heat in the body?
In our body, all organs of the system are involved in the regulation of heat under the guidance of the main ones - the hypothalamus, liver and heart.
The liver, through biochemical reactions, heats the blood. And the heart pumps it, driving it all over the body in order to evenly distribute heat over all areas. That is why the vessels can be rather successfully compared with the pipes of the heating system.
Based on the external temperature, the vessels either shrink to retain heat, or expand to release excess heat outside the body. However, this process can be disrupted due to various pathologies and reasons, because of which a person freezes more in winter, sometimes due to extreme cold.
Sauna Syndrome
Insufficient hemoglobin levels or iron deficiency anemia cause a delay in the timely delivery of oxygen by the blood to tissues and internal organs.
The body is trying to improve the situation in order to supply the organs with oxygen, so the vessels dilate to increase blood flow. Accordingly, heat transfer increases - the body loses the necessary supply of heat, therefore it begins to freeze.
Vitamins A AND E
Lack of vitamins such as A and E, including fat in the diet, can lead to chilliness even in warm weather. In the liver, the biochemical processes that are responsible for heating the blood are imbalanced. As a result, the body cools down.
The fat ones are cold too
It is believed that overweight people should always be hot, because they have a sufficient layer of fat. However, this is not the case. Fatty deposits are a tight compressor, meaning they compress the vessels, leading to a narrowing of blood flow. Inadequate oxygen supply, as well as the body's attempt to compensate for this deficiency, leads to the fact that a person becomes cold.
Capillaries
Cold feet, including hands, are a typical sign of impaired capillary circulation. Warm blood flow simply cannot reach the limbs. Quite often this happens with vegetative dystonia.
Age-related "frostiness", which forces older people to put on several layers of clothing or throw on extra blankets, is also caused by deterioration of vascular functions.
Not enough fuel
Often, people who are daily short of calories, too few, are also doomed to freeze. In the absence of regular calories, the body simply has nowhere to take energy.
If, for example, a person still moves a little, not enough and also thin, then he is doomed to cool down faster. His body temperature also becomes lower.
Diabetes
Diabetes mellitus can cause constant chilliness. The root cause here is serious disturbances in the functioning of the cardiovascular system and in metabolism. Cold feet are a clear sign of diabetes.
Raynaud's disease
There is also a specific cold syndrome called Raynaud's disease. It is expressed in a violation of the arterial blood supply to the extremities. Under the influence of too warm or cold temperatures, emotional stress, such people experience vascular spasm, which is the main cause of thermoregulation disorders.
Perhaps they say about you or your loved ones "freezing" or "freezing": these people are cold both in winter and in summer, they are constantly looking for ways to keep warm. Some are really bad at it low temperatures... For example, those who belong to the southerner genotype, for whom the cold is unacceptable in principle. But most likely it will be one of these 10 reasons.
Sauna syndrome or iron deficiency anemia
Or even simpler: insufficient hemoglobin level in the blood. It causes a delay in the delivery of oxygen by the blood to the internal organs and tissues. The body tries to improve the oxygen supply of the body, and the vessels dilate to increase blood flow. They also behave in the event that there is a suffocating heat or you are in the sauna. Accordingly, heat transfer increases - the body loses the necessary supply of "heating" and freezes.
That is, in the heat, our body tries to cool the body, but here it does the same when you do not need it.
This means that you urgently need to increase the level of iron in the blood. The easiest way to do this is by adjusting your diet. Enrich the menu with red meat, offal, beets, buckwheat, nuts, eggs. As a last resort, buy a hematogen at the pharmacy and use it.
The daily intake of iron should be 15 mg.
Lack of fats and vitamins A and E
It is these substances that are responsible for the balance of biochemical processes in the liver, which contribute to heating. Their lack can lead to constant chilliness even in warm weather.
In general, a certain amount of these substances is already in our body. Therefore, for a start, it is worth again introducing into your diet foods containing a high concentration of retinol and tocopherol. Eat more carrots, pumpkins, cereals, red vegetables and fruits. With the approval of a doctor, you can drink synthetic vitamin complexes.
Also reconsider your attitude towards fats. The main thing is to use healthy fats, which, by the way, are not only necessary for the body, but also contribute to weight loss. These are fatty fish, cheese, eggs, etc. Avoid unhealthy trans fats.
Excessive thinness or fatness
The golden mean is the golden mean because it is difficult to achieve. Overly thin people are characterized by "frostiness", since it is rather difficult for them to accumulate and keep warm in tissues. It is necessary to gain mass, and not necessarily fat, more muscle. In the absence of the required volume of muscle and adipose tissue, the cold penetrates to the bones faster.
Among the plump ones, too, there are a lot of "frozen". Excess body fat is a tight compressor. Compressing the vessels, it leads to a narrowing of the blood flow, which means to an inadequate supply of oxygen to the internal organs. Heat transfer increases again - the heat goes to the side, and the person freezes. In this case, you need to lose weight.
Thyroid problems
For example, hypothyroidism - thyroid dysfunction - may be the cause. It is this organ that is responsible for regulating energy processes in the body - the distribution of energy reserves, including for heating.
For example, in hypothyroidism (thyroid dysfunction), heating processes are disrupted. The formation of heat from the calories received from food is inhibited.
You can understand that the thing is in the thyroid gland by paying attention to the legs - they are cold at any time of the day. If you notice this in yourself, you need to contact an endocrinologist.
Low blood pressure and dysfunction of blood vessels
Still, most often cold feet (and sometimes hands) are a sign of impaired peripheral capillary circulation. The heat just doesn't reach the limbs.
Hypotonics (people with low blood pressure) know what increased "frostiness" is: a decrease in pressure leads to a violation of the blood supply, which, again, becomes the cause of internal "coldness".
In this case, it is worth taking a course of vitamins, increasing physical activity, adding walks in the fresh air, adjusting nutrition (add vegetables and fruits, remove refined food). Hypotensive patients can drink more than 1 cup of tea or coffee a day to slightly increase their blood pressure.
By the way, the deterioration of vascular functions is associated with age. Therefore, the constant chilliness is often inherent in the elderly.
Diabetes
Such a disease becomes the cause of metabolic disorders, as well as serious problems with the cardiovascular system. In such cases, patients often complain of constantly cold feet, which also lose sensitivity. This should be reported to the endocrinologist, who will select an adequate treatment.
Stress
Frequently, "freezing" can be associated with an overloaded nervous system and stress. Moreover, a person begins to freeze the more, the more worried, nervous, frightened or angry.
Raynaud's disease
There is also a specific cold syndrome - Raynaud's disease. It is expressed in a violation of the arterial blood supply to the extremities. At the slightest emotional stress, as well as under the influence of too cold or warm temperatures, such people develop a strong vascular spasm that disrupts thermoregulation.
ABOUT weakening of immunity and hormonal imbalance in the body can cause a feeling of constant cold.
To find out exactly the reasons for your discomfort, you should visit an endocrinologist, cardiologist, vascular surgeon, phlebologist or neurologist.

There are people who are constantly chilly, even in summer, when the sun is hot. It doesn't even matter that such people are dressed for the weather, but they are constantly chilled, and their hands or feet are just icy to the touch. This condition is called chills. True, it should be noted right away that if a person has been freezing since childhood, and the results of all tests are normal, then it means that he has his own temperature comfort zone. In a continental climate, a healthy person can freeze for more than half of the calendar year. In this case, it is enough to dress warmly. But, low cold resistance can talk about some disorders and diseases, so you should consult an endocrinologist, cardiologist and phlebologist. Diabetic patients often have cold hands and feet. What to look for if you are constantly freezing?
Check your thyroid
The thyroid gland is responsible for metabolism and thermoregulation, namely the main hormone produced by it - thyroxine.
When there is not enough thyroxine, it decreases and, accordingly, the person freezes.
Weight gain with a normal diet, hair loss, dry skin, constipation, pressure fluctuations, a constant feeling of fatigue, despite the fact that enough time is devoted to sleep and rest, can indicate a deficiency of hormones that are secreted by the thyroid gland.
You can check the function of the gland by taking a blood test for TSH - thyroid stimulating hormone. If the analysis shows its deficiency, the endocrinologist will prescribe the drug thyroxin in the dosage you need.
Check your hemoglobin level
Low hemoglobin levels can cause persistent coldness or chills. Anemia can be recognized by general analysis blood. And the doctor will prescribe the treatment, taking into account the results of your tests.
The onset of menopause
This is another endocrine cause that can cause chronic chills, hot flashes and increased sweating. The climacteric restructuring of the body cannot be avoided, it just needs to be experienced. With menopause, the functions of the ovaries fade away, therefore it is necessary to maintain them at a good level with the help medicines... Do not be lazy to visit a doctor who, based on the tests, will select the right hormone therapy for you.
Not a balanced diet
Compliance with a strict diet and restricting calories in the diet inevitably leads to a lack of energy in the body, therefore, a malnourished person is constantly cold, since the subcutaneous fatty tissue, which acts as a heat insulator and does not allow internal heat to evaporate too quickly, simply has nowhere to come from.
The companion of anorexia nervosa is a constant feeling of coldness and chilliness.
Check your eating habits. You are used to starting your day with a cup of coffee and smoked cigarettes, then you should not be surprised that you are constantly freezing. Caffeine and nicotine, and even in such a "union", constrict the peripheral vessels, which is especially reflected in the arms and legs. In addition, constant abuse of caffeine and leads to the development of persistent spasm, and then "frostiness" becomes a lifelong companion.
Give up smoking, alcohol (some are even addicted to drugs). To mitigate the withdrawal syndrome and get rid of addictions, you should seek help from a narcologist.
Live stress-free
Stress, anxiety, constant experiences force the body to produce large doses of adrenaline, and adrenaline has a powerful vasoconstrictor property. Those who suffer from nervous disorders or panic attacks often feel chilly and shiver. These conditions are treated by a psychiatrist or psychotherapist.
