When soaking feet, the water temperature should not be too high, just about 40℃. Because the water temperature is too high, the blood in the human body will flow more to the lower limbs after the blood vessels in the feet are excessively dilated, which will easily lead to insufficient blood supply to important organs such as the heart, brain and kidney, and will also destroy the sebum membrane on the skin surface of the feet, making the stratum corneum dry and even chapped. Especially for developing children, soaking feet with overheated water will make plantar ligaments deform and relax, which is not conducive to the development of arch and easy to induce flat feet.

Guiding opinions:

At the same time, the foot soaking time should not be too long, and it is appropriate to 15-20 minutes. When you soak your feet, your blood circulation and heart rate will accelerate. Too long is easy to increase the burden on the heart.
