Bubble reactive oxygen species: 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 with hot water is an excellent method.

Red light function: Stimulate foot acupuncture points, reflex zones and meridians. According to medical theory, there are reflex zones, acupoints and meridians on the feet of various organs and organs of the human body. Many people have done pedicure, and when the masseur presses our feet, it will feel pain and soreness. This situation can basically explain that there is something wrong with the organs in the corresponding reflex zone.

Therefore, after the foot massage, you 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 with hot water is equivalent to stimulating these six meridians.

Extended data:

When you soak your feet in hot water, you will find that the blood vessels on your feet will expand and the epidermis of your feet will turn red. This is because hot water will accelerate the blood circulation of the feet, make more blood flow to the peripheral blood vessels of the lower limbs, and reduce the blood flow of the brain, thus making people feel sleepy.

At the same time, because countless nerve endings on the soles of the feet are closely connected with the brain, the warm stimulation of hot water on the nerve endings on the feet can inhibit the cerebral cortex and make people feel comfortable and relaxed in the brain, thus speeding up sleep and deepening sleep.
