Experts believe that alternating hot and cold shower massage is helpful to promote blood circulation, but it must be hot first and then cold. Hot water can relax blood vessels on the skin surface, relax muscles and help you relax yourself. When the body is warm enough, take a cold bath. This can constrict blood vessels, promote blood circulation and make the body and mind excited.

The shower massage must be carried out after washing the body. First, properly raise the water temperature and strengthen the intensity of water flow. Use massage water to do full body massage, relax muscles and ligaments, focusing on the parts where muscles are tense or ligaments are sore. When the whole body has been warmed up by hot water massage, you can try cold water massage. Cold water massage should be gradual. Don't put your whole body in cold water immediately. You should start with your face, feet or hands, and then slowly lead to * *. If it is difficult to accept cold water, you can take a shower from your feet to your knees and from your hands to your elbows. Move up a little every day, and you will get used to it.
