If you bathe in cold water immediately after sweating heavily, it will stimulate the dilated blood vessels to contract sharply, weaken the transmission function of blood nerve endings, and easily lead to venous thrombosis or severe coma or shock due to reduced blood volume. So we don't advocate taking a bath immediately after exercise. General rest 15 ~ 30 minutes, and it is safer to clean after all the body systems are restored to normal level ~ ~
