Foot bath can promote the blood circulation of human feet, improve the meridians of feet and promote human health.

Foot bath promotes blood circulation. The foot has been considered as the second heart of the human body since ancient times. 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 cause poor blood circulation. Medical classics record: "A man with feet is still like a tree with roots. When the tree dies, the roots are exhausted first, and the old feet decline first. " Especially for people who often feel cold hands and feet, soaking feet with hot water is an excellent method.
