Cold soles seem to be a problem for most women in Taiwan Province Province, and cold soles can also reduce the quality of sleep. A study by Kurume University in Japan pointed out that the temperature of the soles of the feet is 3 degrees lower than that of people who are prone to sleep. In order to have a good sleep, doing simple ankle movements every day can help you fall asleep and eliminate leg edema. Cold soles easily affect sleep and digestion and absorption functions. Ankle exercise can improve cold soles, eliminate edema and stovepipe. The reason why the feet are cold is that the blood circulation of the body is not good, and blood and heat cannot be sent to the toes. Poor blood circulation may be due to insufficient exercise, high pressure and eating too much cold food, which makes blood vessels contract. Making the blood circulation better and the soles of your feet no longer cold can not only make you have a good sleep quality, but also improve the function of internal organs, make digestion and absorption better, and no longer feel easily tired. Japanese slimming authority Tian said that ankle exercise can make ankles soft, blood can be sent to toes more smoothly, and blood circulation will be improved, thus improving the body's metabolism.
