2, foot bath is not suitable for everyone, like diabetes, varicose veins patients and children should pay attention.

3. The water temperature for soaking feet should not be too high, and about 40℃ is appropriate. Excessive water temperature is harmful to patients with cardiovascular and cerebrovascular diseases. At the same time, if the water temperature is too high, it is easy to destroy the sebum membrane on the skin surface of the foot, making the stratum corneum dry or even chapped.

4, foot bath time should not be too long, each foot bath time is best not to exceed half an hour, because the human blood circulation and heart rate will accelerate when soaking feet, and too long will increase the burden on the heart.

When you are not sure about the temperature of water when soaking your feet with your hands, it is suggested to try it with your hands instead of your feet, because your hands are more sensitive to temperature than your feet. For patients with diabetic foot, measure the temperature with a thermometer when washing feet to avoid scalding.

Hot water soaking feet is not so magical.

When the feet are soaked in hot water, the blood vessels around the legs and feet will expand and the blood flow of the skin of the feet will increase due to the increase of environmental temperature. However, in a short period of time, this change of local circulation will hardly affect the whole body circulation, or even affect the core body temperature like bathing or showering. So for healthy people, soaking feet may not cause much physical changes, so it is useless to expect soaking feet to treat various diseases.
