Foot bath water should not be too hot, about 40℃ is appropriate.

First, the foot soaking time should not be too long, and 15-30 minutes is appropriate. In the process of soaking feet, due to the accelerated blood circulation, the heart rate is faster than usual. Too long, it is easy to increase the burden on the heart. In addition, because more blood will rush to the lower limbs, people with weak constitution are prone to dizziness due to insufficient blood supply to the brain, and even faint in severe cases. Among them, patients with cardiovascular and cerebrovascular diseases and the elderly should pay special attention. If you feel chest tightness and dizziness, you should temporarily stop soaking your feet and lie in bed immediately.
