Young people are strong, so it's no problem to soak for a while. If you are old, you should master the rhythm.

Especially for patients with heart disease, don't use too hot water or soak it for too long, because hot water will accelerate the blood flow to the feet, and the blood supply to the heart may be insufficient.

In addition, if you massage the soles of your feet properly when soaking your feet, the health care effect will be better.
