1. If you have athlete's foot, don't soak your feet in an infected state (except for foot-soaking pills specifically for athlete's foot, such as Zuguang pills). 2. If you have severe heart disease or hypoglycemia, try not to soak your feet with overheated water to avoid fainting. 3. It is not advisable to soak your feet when you are too full or hungry before eating, because soaking your feet will accelerate blood circulation, reduce blood in your stomach and affect digestion. 4. Hypertensive patients should not soak their feet with overheated water. If you accept my answer, I hope you can help me adopt it.
