In the summer, people have the habit of immediately wiping off sweat. Little do they know that doing so reduces the function of skin temperature regulation, and is actually not conducive to heat dissipation on the surface of the body.
In high temperature conditions, when the body's heat production increases, the sweat glands secrete a large amount of sweat, which adheres to the surface of the skin and can play a role in cooling down through evaporation.
Therefore, if the sweat is immediately wiped off, it cannot perform its function of evaporative cooling. At the same time, because the heat is not dissipated, the sweat glands will continue to secrete sweat, and the body's salt and vitamins will also be consumed, which is detrimental to health.
The skin that has already sweated should not be wiped with cold water or a cold towel. Instead, it should be wiped with warm water or a warm towel.
Because the skin is stimulated by cold, the pores will close, and the capillaries will contract, preventing the dissipation of accumulated heat. At this time, the body will feel hot and uncomfortable.
If warm water is used, the skin surface will be stimulated by heat, and the pores will quickly open, along with the expansion of capillaries. This will facilitate the faster and more efficient dissipation of heat, making the body feel cool and comfortable quickly.
