Modern medicine has proved that "old feet get old first", "cold starts from feet" and "look down on one pair of feet and add frost to the head", which shows that the health of feet is not only related to people's health, but also has a great relationship with life span. Because there are countless nerve endings on the soles of the feet, which are closely connected with the brain and densely covered with countless blood vessels, it is called the "second heart". In addition, the soles of the feet are far away from the heart, the blood supply is low, the surface fat is thin, and the temperature is low, which is closely related to the upper respiratory tract, especially the nasal mucosa. Therefore, once the soles of the feet catch cold, the local body temperature of the upper respiratory tract will drop and the resistance will weaken, leading to many diseases such as colds. As a benign stimulus, foot bath can regulate autonomic nerve and endocrine system, which is beneficial to the proliferation of brain cells and enhance people's memory. At the same time, it can dilate blood vessels on the body surface and improve blood circulation. Visible, foot bath is of great benefit to people's physical and mental health.
