The correct way: First, take a proper amount of warm water in the footbath, neither too hot nor too cold, and the water depth should just cover the foot surface. First soak your feet in the footbath for 5- 10 minutes, and then rub your back, heart and toes repeatedly with your hands or towels. You can also rub the calf repeatedly until the skin on the leg is red and hot. At this time, you can heat the water while kneading, and finally the water can be added above the ankle. Wash and dry with a dry towel repeatedly after washing. Before going to bed at night, it is best to soak your feet for health, so it is advisable to take 20-30 minutes each time, and it is best to go to bed within half an hour after washing.
