Interestingly, "one pot of soup before going to bed", a physical therapy for insomnia in the elderly, has become the secret of many people's health.

All parts of a person are a unified whole. Washing feet with cold water will not only cause the blood vessels in the feet to contract violently, but also other parts that are not stimulated by cold water will change to varying degrees. It is observed that when people's feet are affected by cold water, at first, the blood vessels contract reflexively, the blood flow decreases, and the temperature of nasal mucosa drops obviously; After a certain period of time, the blood vessels in the foot began to expand, and the temperature of the nasal mucosa also increased. After a few minutes, it shows a more intense increase, accompanied by runny nose and sneezing. If you wash your feet with warm water and gradually lower the water temperature, the above symptoms will not appear.

At the same time, washing feet with cold water will not only affect the nasal mucosa, but also increase the temperature of skin, viscera and muscles in the cold parts.

Actually, this is a misunderstanding.

As the saying goes, "Cold starts from the soles of your feet." Because the human foot is the distal part of the blood vessel branch,

It is prone to peripheral blood circulation disorder and lack of sebaceous glands on the soles of the feet, so it is very sensitive to cold. Someone has done experiments. If you put your feet in cold water at 4℃, the reflex will cause vasoconstriction of nasal mucosa, and symptoms such as runny nose and sneezing will appear after three minutes.

Men will sweat more in hot summer, especially after exercise. At this time, suddenly washing feet with cold water will suddenly close and block the expanded pores.

Not only for men, but also for women, every time menstruation comes, it means that the whole body or part of the resistance drops and it is easier to get sick. At this time, if you wash your feet with cold water, cold stimulation will also cause vasoconstriction and blood volume reduction, which will make the blood circulation of uterus and pelvic cavity disorder and lead to gynecological diseases.
