First, promote blood washing cycle. From top to bottom, there is a talent for adding salt to the human body. According to the theory of keeping in good health, the foot is farthest from the human heart and bears the heaviest burden. So this place is most likely to lead to a bad blood washing cycle. According to medical records, "a man with feet is still like a tree with roots. The roots are exhausted first, and the old feet are old first." Especially for people who often feel cold hands and feet, soaking feet is an excellent method.

Second, stimulate the acupoints of the foot and the meridians in the reflex zone. Many people have done pedicure. When the masseur presses our feet, it will feel pain and soreness, which basically shows that there is something wrong with the corresponding organs in our reflex zone. Therefore, when we finish the foot massage, we will feel relaxed all over. At the same time, there are six main meridians on people's feet, including the termination points of three yang meridians (bladder meridian, stomach meridian and gallbladder meridian) and the starting points of three yin meridians (spleen meridian, liver meridian and kidney meridian), so soaking feet is equivalent to stimulating these six main meridians.

Third, it has a good auxiliary effect on the treatment of many diseases. People often say: "the rich take tonic, and the poor soak their feet." It can be seen that soaking feet plays a great role. Especially in modern society, the extensive use of air conditioners and people's general love of cold food make their bodies cold and wet. By soaking your feet, you can accelerate the discharge of cold in your body.
