Soaking feet with hot water is very beneficial to the blood circulation of the body, but hot water should not be too high and the time should not be too long. Fifteen minutes is appropriate. During soaking, you can also massage your head or pat your shoulders to promote blood circulation throughout your body. Finally, you can drink some jujube water, which can replenish blood. I tried it myself for a while and it was not bad. But it takes a long time to see the effect.
