It is best to drink water half an hour after exercise, and do light exercise for a period of time during this half an hour to slow down the heartbeat to normal and let the body temperature slowly drop to normal body surface temperature. The best way is to walk slowly. After walking, you can do muscle stretching, then drink water to replenish the water lost by sweating. Drink light salt water at most. If you feel particularly tired, you can supplement sports functional drinks. At this time, the skin pores of the body slowly return to normal from the opening. You can take a bath at this time, but don't take a cold shower. Don't take a bath like this even if it is particularly hot in summer. Be sure to take a bath with water above body temperature, which will promote blood circulation in the body and promote gastrointestinal digestion.
