During exercise, blood vessels on the body surface dilate, body temperature rises, pores relax, and perspiration increases. Walking into the air-conditioned room immediately after exercise or taking a cold nap at the fan outlet will make the skin tense and sweat, leading to physiological disorders such as temperature regulation and decreased immune function, which will lead to colds, diarrhea and asthma.

Things forbidden after exercise:

1, don't drink a lot of water immediately after exercise.

Because of continuous exercise, the body sweats a lot, leading to the outflow of inorganic salts (mainly sodium) in the body, and the salt content in the blood is relatively low. If you drink a lot of water at this time, the salt content in the blood will drop sharply, and sweating will make the salt more easily lost, thus reducing the osmotic pressure of cells, leading to the imbalance of sodium metabolism and easily leading to muscle cramps.

Don't eat immediately after exercise.

After fitness, the motor nerve center is in a state of high excitement. In this case, the parasympathetic nervous system, which manages the activities of internal organs, strengthens the inhibition of digestive system activities. Moreover, when people exercise, the whole body blood intensively supplies the needs of moving organs, while the supply of various organs in the abdominal cavity is relatively reduced. If you eat in a hurry at this time, it will increase the burden of digestive organs, cause gastrointestinal dysfunction, and even cause various diseases.
