It is wise to take a cold or warm bath immediately after fitness exercise. This is because, for a long time after exercise, the skin blood vessels have been in a state of obvious expansion, and the skin blood flow is relatively high. At this time, the blood pressure of the body is relatively low. In this state, if you take a bath with cold water, it will lead to a sharp contraction of skin blood vessels, which will lead to an increase in blood pressure and increase the burden on the cardiovascular system, which is dangerous to some extent.
Be sure to remove makeup before exercise! Otherwise, the pores will be blocked by grease particles, you will sweat a lot after exercise, and you must wash your face. It is better to wash your face before bathing, because bathing will open the pores of your face, and dirty things will enter the pores after sweating. After fitness, you can drink some water first, replenish some water lost from your body and wash your face. It is recommended to take a rest for about 30 minutes, and then take a bath when the body returns to the state before fitness. The water temperature is close to the body temperature, and the optimal water temperature is 35-37 degrees.
Because the metabolic process of the body is strengthened during exercise, the subcutaneous blood vessels dilate and sweat a lot, and a cold bath is taken immediately after exercise, so that a large amount of heat generated in the body can not be well distributed, and the open pores allow cold water to enter, forming internal heat and external cold, destroying the balance of the human body, causing endocrine disorders, leading to colds and serious rheumatic diseases.
