It is 40℃ in Chongqing, and I don't sweat. What is wrong with me?

When the weather is hot and humid, people will sweat with a little activity, which is beneficial to heat dissipation and maintain normal body temperature, but some people are not so easy to sweat. Such people must first rule out the following diseases:

1. Congenital hypoplasia of sweat glands or absence of sweat glands can be manifested as systemic or localized anhidrosis.

2, some skin diseases, such as severe ichthyosis, scleroderma, leprosy, radiation dermatitis, skin atrophy and so on. , can cause local anhidrosis.

3. Some nerve injuries, such as transverse myelitis, poliomyelitis, paraplegia, and local injuries of sympathetic nerve, medulla oblongata and pons, can cause systemic or local anhidrosis.

4. Some medical diseases, such as diabetes, diabetes insipidus, chronic nephritis, mucinous edema, malignant tumor, vitamin A deficiency, etc., can also cause systemic anhidrosis.

Patients with yang deficiency who are not easy to sweat in summer generally belong to spleen and kidney yang deficiency type. Such patients should pay attention to eating less cold food and not staying in air-conditioned rooms for too long. Usually, under the guidance of Chinese medicine, you can eat some relatively warm food with Chinese medicine decoction for conditioning.

People with physical conditions may wish to participate in 1-2 times a week, such as badminton, football, etc., so that they can experience the feeling of "sweating like rain" to strengthen the metabolic function of the skin. In addition, even in hot summer, outdoor activities can be carried out before 10 in the morning and after 5 pm, so that the body can feel the temperature of nature and sweat slightly, which is actually beneficial to health.

Don't sweat on a hot day, be careful of "heatstroke"

"heatstroke" is a very serious heatstroke. In the high temperature environment, the body's thermoregulation function is unbalanced, and the heat in the body cannot be dissipated, resulting in a large amount of savings, leading to high fever, coma and other symptoms. The common manifestations of patients are: high fever, body temperature above 40℃, dry and hot skin without sweat, mental disorder, organ failure and so on. If not treated properly in time, the mortality rate is as high as 50%-70%.

The human body needs to emit heat in different ways, such as breathing and sweating. If the air humidity is too high, the perspiration function will be disordered. Sweating mainly depends on evaporation to remove moisture from the skin surface, so that the human body will be cool. When the humidity is high, there will be more water vapor in the air, and evaporation will be reduced, so it is difficult to cool yourself.

In a hot environment, when the body temperature rises, the body will dissipate heat and lower the body temperature by increasing sweating and breathing times. However, if the ambient temperature is too high, the body temperature rises sharply, and the body is short of water, there will be heat failure, and the symptoms include dizziness, headache, nausea, shortness of breath and confusion.

If the body temperature rises again and fails to dissipate heat in time, it is more likely to have a general spasm or coma, that is, heatstroke. At this time, the patient must be cooled down and given first aid in time, otherwise his life will be in danger.

Therefore, once someone is in a high temperature environment but doesn't sweat, be sure to be vigilant, because it may have heatstroke by this time.
