First, promote blood circulation. The foot has been considered as the second heart of the human body since ancient times. According to the health theory, the feet are farthest from the human heart and bear the heaviest burden. So this place is most likely to cause poor blood circulation. 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, reflex zones and meridians of the foot. Many people have had pedicures. As soon as the masseur presses our feet, they will feel pain and swelling. This situation can basically explain that there is something wrong with our corresponding visceral 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 end points of three yang meridians (bladder meridian, stomach meridian and gallbladder meridian) and the beginning points of three yin meridians (spleen meridian, liver meridian and kidney meridian), all of which are on the feet. So soaking feet is equivalent to stimulating these six meridians.

Third, it has a good auxiliary effect on the treatment of many diseases. It is often said that "the rich take tonic, while 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.
