Soaking feet before bedtime is good for human health if done properly. First of all, it can promote blood circulation in the feet, improve the blood supply to the extremities, and treat some wind-cold and rheumatic diseases. Secondly, it can massage the acupuncture points of the feet, producing a certain systemic adjustment effect. It can also help the spirit to relax and help sleep. But note that the water temperature of the foot soak should not be too high and the time should not be too long, otherwise on the one hand, it may cause some stimulation to the skin of the feet. On the other hand, if the blood vessels are dilated for too long, it may aggravate the burden of cardiovascular disease and lead to aggravation of cardiovascular disease. Feet that suffer from more obvious fungal infections such as tinea pedis, soaking the feet in hotter water may aggravate local inflammation, increase itching, and even induce ringworm rash.
