In the hot summer, sweating profusely, most people will habitually wipe it off immediately. Little did they know that there is also a way to determine whether to wipe sweat in summer. Some people are puzzled: Isn’t sweating something that can’t be wiped off? You can’t say that, there are really some tricks. Today, Guoguo will take everyone to see what the experts say:

When your body temperature cannot be lowered immediately and the external environmental temperature does not change significantly, it is not advisable to wipe it off immediately. Because the sweat on the surface of the body helps to lower the body temperature, if it is wiped off immediately, it is not conducive to the body’s surface heat dissipation. The body needs to continue sweating, and the main way for the body to dissipate heat is through the radiation, conduction, convection, and evaporation of sweat on the skin surface. When the body produces more heat under high temperatures, the sweat glands will secrete a large amount of sweat, which attaches to the surface of the skin. When the sweat changes from a liquid to a gaseous state, it will take away a large amount of heat, which can play a role in heat dissipation and cooling. Therefore, if sweat is wiped off immediately after sweating, it cannot exert its evaporative heat dissipation effect; at the same time, since the heat has not been dispersed, the sweat glands will continue to secrete sweat, and the salt, vitamins, and other substances in the body will also be consumed, which is not good for health.

On the contrary, if the skin of the body sweats and enters an air-conditioned room, it is best to first wipe away the sweat with a dry towel or a warm towel, but it is not advisable to use cold water or a cold towel, and to avoid the direct breeze of cold wind, in order to prevent the wind from blowing and the capillaries from opening, the sweat from being blocked, and feeling cold and damp. The reason for wiping the sweat first is that the skin is stimulated by the cold, the pores will close, and the capillaries will also contract, the accumulated heat in the body cannot be released, and at this time, the body will feel hot and stuffy. If warm water is used, the skin surface is stimulated by heat, the pores can quickly open, and the capillaries will expand accordingly, and the heat will be released more and faster, and the body will feel cool and comfortable quickly.

After sweating, one must pay attention not to use a wet and cold towel to wipe the skin or take a cold shower, but instead to use a hot towel to wipe away the sweat, rest for a while, and allow the sweat pores to gradually contract before entering an air-conditioned room or taking a hot bath. In summer, it is often heard that people complain of lower back pain and stiff shoulders, feeling heavy and stuffy, which is also due to the long-term sweating and rapid entry into an air-conditioned room, suddenly being blown by cold wind and wetness, which is also the discomfort caused by the ‘six evils’ such as wind, cold, and dampness mentioned in traditional Chinese medicine.
