Modern medicine believes that, on the one hand, the feet are farthest from the heart and have a poorer blood supply; in addition, the fat layer on the surface of the feet is thin and has poor thermal insulation ability, so the skin temperature of the feet is also the lowest, with the temperature of the toes as low as 25°C, while the normal human body temperature is generally around 36.5°C. In addition, there is a close nerve connection between the feet and the upper respiratory tract mucosa. Therefore, once the feet are cold, it can reactively cause the capillaries in the upper respiratory tract mucosa to contract, the cilia to beat more slowly, and the resistance to disease is significantly reduced. At this time, the bacteria and viruses that had been lurking in the nasopharynx will take advantage of the opportunity to enter the body and multiply in large numbers, causing people to catch colds, respiratory tract infections, abdominal pain, back and leg pain, dysmenorrhea in women and other symptoms.

There are also in-depth studies abroad on the relationship between feet and body health. The human feet are covered with receptors at the nerve endings. The cold sensation of the feet can be connected to the brain's "body temperature regulation center" through complex neurophysiological activities. The feet gather 6 meridians, 66 acupoints, and 72 reaction points connected to the organs, just like the foundation of a high-rise building. There are many diseases caused by cold feet, such as frostbite, arthritis, thromboangiitis obliterans, heel disease, and foot numbness are all related to cold, especially for patients with trauma, postoperative, long-term illness, and serious illness. It may even cause systemic infection and further deterioration of the disease. Therefore, keeping the feet warm is extremely important in disease prevention.

In cold seasons such as autumn and winter, you can also wear some electronic functional clothing, such as electronic remote-controlled massage shoes, wire-controlled heating shoes, thermal power heating shoes, electronic thermal clothing, and other heating clothing to provide warmth whenever needed.
