In the scorching summer, people wearing light and cool shoes or slippers often like to wash their feet with cold water. Some people wash their feet with cold water, blow them dry with a fan, and then put on shoes. Little do they know that regularly washing feet with cold water in summer can be detrimental to health.
The saying "chills start from the feet" has some truth to it. The feet have many acupoints, accounting for 1/10 of the body's acupoints. The feet are the furthest peripheral part of the blood vessels. The fat layer on the feet is thin and has poor insulation. The soles of the feet are the coldest part of the body, making them very susceptible to cold. If you frequently wash your feet with cold water in summer, it may cause your feet to catch a chill, leading to various diseases.
In addition, the sweat glands on the soles of the feet are well-developed. Suddenly washing the feet with cold water can cause the pores to close abruptly and become blocked. Over time, this can cause sweating dysfunction, especially when the sensory nerve endings on the feet are stimulated by cold water, the blood vessels and tissues that normally function will contract sharply. Eventually, this can lead to dysfunction of dilation and induce arthritis, rheumatism, and other conditions. Staying barefoot in a cool air-conditioned room for a long time can also cause the same harm to the body.
Especially for women during menstruation, they should pay more attention to keeping their feet warm because the pelvic area of women is significantly congested during this time, and the excitability of the cerebral cortex decreases, resulting in a corresponding decrease in the body's resistance. If the feet are exposed to cold and chilly stimuli, it can reflexively cause spasm and contraction of the blood vessels in the uterus and pelvic cavity, leading to dysmenorrhea, amenorrhea, and other gynecological diseases.
