1, from the health point of view, people sweat the most in summer, especially those who wear leather shoes, and the smell is quite unpleasant. The water flowing from top to bottom in the bath can basically wash away most of the sweat and dirt on the feet, but it can't wash the feet and feet. Therefore, between the feet and the soles of the feet, it is necessary to wash them carefully in order to clean the odor.
2. From the point of view of health care, the soles of the feet are rich in spiritual endings and acupoints, which have great influence on human health. As the saying goes, "a cold starts with the feet" is the truth. It is better to stay healthy than to cure diseases. Soaking feet with warm water of about 50 degrees before going to bed can promote blood circulation, prevent insomnia, drive away cold and so on. If you can massage the acupoints properly at the same time, the effect will be better.
