I don’t sweat even when it’s hot in summer. Am I sick?

If you are not sweating in the hot summer with a temperature of 38°C outside, then you should be careful. If you are not sweating when you should be sweating, it may be a problem with your body. Sweating can not only regulate body temperature, but also help the body excrete some metabolic waste. What is the reason for not sweating?

Why don't you sweat?

1. Congenital hypoplasia of sweat glands or lack of sweat glands can manifest as systemic or localized anhidrosis.

2. Certain skin diseases, such as severe ichthyosis, scleroderma, leprosy, radiation dermatitis, skin atrophy, etc., can cause localized anhidrosis.

3. Certain nerve injuries, such as transverse myelitis, poliomyelitis, paralysis, and local damage to the sympathetic nerves, medulla oblongata, and pons can cause systemic or localized anhidrosis.

4. Certain medical diseases, such as diabetes, diabetes insipidus, chronic nephritis, myxedema, malignant tumors, vitamin A deficiency, etc., can also cause systemic anhidrosis.

Don't sweat in hot weather, beware of heat stroke

"Heat stroke" is a very serious form of heat stroke. In a high temperature environment, the body's temperature regulation function is disturbed, and the body's heat cannot be dissipated but accumulates in large quantities, leading to symptoms such as high fever and coma. Patients usually show symptoms such as high fever, body temperature above 40°C, dry and hot skin without sweat, mental disorders, organ failure, etc. If not treated promptly and properly, the mortality rate is as high as 50%-70%.
