Generally speaking, it is better to soak your feet for 20 minutes before going to bed every day, preferably not more than half an hour. Especially for the elderly, if they soak their feet for too long, they will have symptoms such as sweating and palpitation. Pregnant women should not soak their feet in hot water for a long time.

Some foot baths are exaggerated in propaganda, claiming that they can treat certain diseases. Yin Zhichao pointed out that foot bath is mainly for health care and has no therapeutic effect. In addition, many people directly adjust the massage function when using the foot massager, which is not scientific enough. Before doing foot massage, be sure to soak your feet with hot water, which can speed up blood circulation, relax muscles and ligaments and avoid injury during massage.
