Extended data:

The foot washing time should not be too long, and it is best to control it at 15-20 minutes. If the time is too long, the local blood circulation in the foot is too fast for a long time, and the blood in the body will flow more to the lower limbs, resulting in cardiovascular overload.

The water temperature should not be too high. Many people think that the higher the water temperature, the better as long as it is within their tolerance, but it is not. The best water temperature for soaking feet is below 50℃, which requires hot but not scalding. Feel the water temperature with your feet instead of your hands.

It is not advisable to soak your feet within half an hour after a meal. It will affect the blood supply to your stomach, which will lead to malnutrition in the long run.
