The foot is called the second heart of the human body, which consists of the arch, bones, ligaments, muscles and tendons. Foot occupies less than 2% of the body surface area, but it contains 26 bones, 29 joints, 42 muscles and 25 tendons, and bears the heavy responsibility of supporting the body. People walk about 18000 steps every day. In a person's life, two feet walk around the earth about five times. Feet are so hard, of course, they deserve good care.

The structure of the foot.

The foot has many bones and few soft tissues, and its plane outline is hexagonal. Foot bones are arranged into three arches, namely lateral longitudinal arch, medial longitudinal arch and transverse arch, which form the basis of foot shape. The curvature of the medial longitudinal arch is greater than that of the lateral longitudinal arch, which is a remarkable feature of the foot shape. There are three negative points in the foot, namely calcaneal tubercle, metatarsal 1 and metatarsal 5. Almost all the muscles of the foot are distributed on the sole of the foot, and the tendons of the instep are radially distributed from the ankle joint to each toe. The skin on the dorsum of the foot is thin, with good color, and there is a lack of adipose tissue in the superficial fascia. The outline of superficial vein and tendon of dorsum pedis can be seen through the skin. When the foot makes various movements, the outline of the tendon is displayed more clearly. There are obvious gender differences in the shape of feet: male feet are wide and thick, toes are thick and square, and the lateral protrusions of 1 metatarsophalangeal joint and fifth metatarsophalangeal joint are obvious. Compared with men, women have narrow and thin feet, slender and slightly pointed toes, and more subcutaneous tissue on the instep than men.

From the perspective of prolonging life, it is of great significance to protect the foot and attach importance to the health care of the foot to maintain human health and prolong life. Traditional Chinese medicine believes that the foot is the foundation of human beings, and there are six meridians in the the twelve meridians of human body tied to the foot. These meridians are channels that run qi and blood, connect zang-fu organs, communicate exterior and interior, and run through the upper and lower parts. There are as many as 33 acupoints on the feet, accounting for110 of the whole body. They are like organs on the assembly line, which play an important role in maintaining smooth flow of qi and blood, coordinating zang-fu organs, connecting tissues and organs of the whole body, and regulating life activities. Therefore, treating your feet well is of great benefit to longevity and health care. You can take the following measures to protect your feet, strengthen your body and prolong your life.

Pay attention to wearing shoes and socks. Shoes and socks should be loose but not tight. Too tight shoes and socks will squeeze your feet and hinder the smooth flow of blood. Women who love beauty usually wear as little or no high heels as possible, and buy themselves some comfortable and light cloth shoes and sneakers.

Pay attention to keep your feet warm. The foot is the farthest part of the body from the heart, with little blood supply and weak surface fat layer. Therefore, the warm-keeping function of the foot itself is poor, and there is a close nerve connection between the foot and the respiratory mucosa. Once the feet catch cold, it can reflexively cause the microvascular contraction of the upper respiratory mucosa, slow down the cilia movement, and obviously reduce the human body's ability to resist viruses, bacteria and other pathogenic substances. Therefore, when the climate is cold, women should pay attention to keep their feet warm and choose soft, dry and breathable shoes and socks.

Soaking feet with hot water 15 minutes before going to bed every day can achieve good health care effect.
