Soak your feet in a high bucket and relax the meridians on your feet and calves through heat, thus speeding up blood circulation and improving blood supply to organs such as the heart and brain. With the continuous increase of heat, you will sweat slightly, which can dredge meridians, discharge cold and waste in the body, regulate body temperature and reduce virtual fire. In addition, the improvement of blood circulation has a very obvious two-way adjustment effect on blood pressure. So I suggest that my friends must spend half an hour relaxing and adjusting themselves after a busy day. Don't underestimate this half-hour, as long as you persist every day, just soaking your feet can make you healthy.
