During exercise, the blood vessels on the body surface dilate, the body temperature rises, and the pores relax and sweat. If you go into an air-conditioned room immediately after exercise or blow dry your sweat against the wind, or use a cold water punch to cool down, your skin will suddenly lock up and stop sweating, which will cause physiological dysfunction such as body temperature regulation, and children with decreased immune function will lead to diseases such as colds and diarrhea.

The correct method: wash with warm water, dry clothes and naturally cool down.
