1, hot water can promote the blood circulation of subcutaneous and muscle tissues, and can reduce the concentration of lactic acid produced by exercise more quickly.
2, can reduce muscle fatigue after exercise, and can make people recover their vitality faster.
It is recommended not to take a bath immediately after exercise for the following reasons:
1, because the metabolic process of the body is strengthened during exercise, the subcutaneous blood vessels dilate and sweat a lot. Take a cold bath immediately after exercise, so that a lot of heat generated in the body can not be dissipated well, forming internal heat and external cooling, destroying the balance of the human body and easily getting sick.
2, because during exercise, the blood flow to the muscles increases and the heart rate is recalled. After stopping exercise, this situation will continue for some time. If you take a hot bath at this time, your blood will not be enough to supply other important organs.
Precautions: Take a rest after exercise (subject to the pulse returning to near normal number) before taking a bath, preferably taking a warm bath.
