1. When the ambient temperature changes little, the sweat should not be wiped off immediately, which is not conducive to heat dissipation on the body surface.
If you continue to sweat, that is, your body temperature can't drop immediately, and the ambient temperature doesn't change much, it's not suitable for wiping sweat. The reason for this is to use sweat on the body surface to evaporate heat and help the skin lower its body temperature.
The heat dissipation of human body is mainly realized by radiation, conduction, convection and evaporation of sweat on the skin surface. At high temperature, the human body produces more heat, and sweat glands secrete a lot of sweat and attach to the skin surface. When sweat changes from liquid to gas, it will take away a lot of heat, which can play a role in cooling down.
Therefore, if you wipe it off immediately after sweating, you can't play its role of evaporation and heat dissipation; At the same time, because the heat is not distributed, sweat glands will continue to secrete sweat, and the salt and vitamins in the body will also be consumed, which is not conducive to health.
2. When entering the air-conditioned room after sweating, wipe it with a dry hot towel or a warm towel.
If you enter the air-conditioned room after sweating, it is best to wipe the sweat with a dry towel or a warm towel, not with cold water or a cold towel, so as to avoid the cold wind blowing directly, so as to avoid the blockage of sweat glands when the capillaries are open.
When the skin is stimulated by cold, the pores will close, the capillaries will contract, and the accumulated heat in the body will not be emitted. At this time, the human body will feel sultry.
If warm water is used, the skin surface will be stimulated by heat, the pores will open rapidly, the capillaries will expand, and the heat will dissipate faster, and the human body will soon feel cool and comfortable.
