"Washing feet in spring, the sun rises and takes off; Washing feet in summer can dispel summer heat and dampness; Wash feet in autumn, moisten lungs and intestines; Wash your feet in winter, and Dantian is warm. " This folk song tells the truth that soaking feet can keep fit. From the point of view of meridian science, the functions of human internal organs have corresponding acupoints on the feet, and the feet are both the starting point of Yin San Meridian of Foot and the end point of Sanyang Meridian of Foot. The roots of these six meridians are all in six acupoints on the foot. There are 33 acupoints directly below the ankle and 66 acupoints on both feet, accounting for110 of all acupoints. Often soaking feet will stimulate many acupoints on the foot, such as Yongquan, Taichong, Bai Yin and Kunlun. , will promote the movement of blood into the body, regulate viscera, balance yin and yang, dredge meridians, strengthen the body, delay aging, eliminate diseases and prolong life. Therefore, these proverbs are true: "It's better to take tonic if you wash your feet every day", "It's better to go to bed if you eat a sheep for three days" and "It's hard to cool your feet if you wash your feet every night".
Modern medicine has also confirmed that "people get old when they get old", "cold starts from the feet" and "look down on one pair of feet and add frost to their heads", indicating that the health of feet is not only related to people's health, but also has a great relationship with people's life span. Because there are countless nerve endings on the soles of the feet, which are closely connected with the brain; At the same time, it is densely covered with many blood vessels, so it is called the "second heart". In addition, the soles of the feet are far away from the heart, with little blood supply, thin surface fat and poor thermal insulation, and are in close contact with the nerves of the upper respiratory tract, especially the nasal mucosa. Therefore, once the soles of the feet catch cold, it can cause local body temperature drop, weaken the resistance of the upper respiratory tract, and lead to many diseases such as colds. As a benign stimulus, foot bath can regulate autonomic nerve and endocrine system; It is also 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. It can be seen that pedicure is of great benefit to people's physical and mental health
Practice shows that foot bath is a reliable local infiltration therapy. It can not only prevent foot diseases such as beriberi, foot pads, frozen feet and chapped feet, but also prevent numbness, soreness and chills of lower limbs. Swelling and other diseases are also used to prevent and treat colds, arthritis and high blood pressure because of the role of meridians. Neurasthenia, dizziness, insomnia, constipation and other diseases also have definite curative effects.
