Chapped feet and long cocoons appear in autumn. In addition to climatic reasons, sweat gland secretion naturally decreases when the weather is not hot, which is more likely to aggravate the dryness of the skin. At the same time, because the skin on the heel has become thick and inelastic, coupled with the pull of external forces such as walking, cracks are prone to occur. Therefore, foot care should be prepared for prevention at ordinary times. When washing feet, especially in cold weather, use less alkaline soap and medicated soap. You can often soak your feet in hot water. A simple and convenient way to soak feet is to stir-fry water with pepper, which can not only dispel the cold of the body, but also promote the yang in the body, and has good effects in sterilization, itching relief, detumescence and disinfection. If the stratum corneum is thick and cracked, you can slowly cut off the cracked rough skin with a sterilized blade, and remember to apply vegetable oil, moisturizer or vaseline after cutting. You can also take vitamin A and vitamin E, and eat more fresh fruits and vegetables to help prevent chapped skin. In the choice of shoes and socks, don't choose shoes that are too tight and too narrow, otherwise it will affect the blood circulation of the feet. If you have time, you can massage your feet and rub them properly to keep them in a normal state. Insist on washing feet and changing socks every day. It is best to change shoes and socks once a day.
