A non-sweating body has the advantage of avoiding the discomfort, odor, and staining of clothing caused by sweat, but non-sweating has the disadvantage of affecting the body’s ability to dissipate heat and causing the skin to dry out. There is a direct relationship between the lack of sweating and an individual’s constitution, and it is not normal to not sweat even after activity or in hot weather. The body discharges heat from the body through sweat, and if you don’t sweat, it can easily cause heat stroke and other diseases. And a long time without sweating skin is also prone to dryness, sometimes itching, or other skin diseases. In addition, sweat on the surface of the skin can prevent microbial invasion, a long time without sweating skin barrier function is weak, easy to induce infections and so on. No sweat can avoid the discomfort, odor, dirty clothes, etc., but if there is a long period of no sweat, it is recommended that the hospital consultation, standardized treatment under the guidance of a physician, do not blindly deal with their own, so as not to cause adverse reactions.
