The ancients thought that sexual intercourse between men and women was a very important item in health preservation, so there were many taboos. Among them, related to disease health are:

As the saying goes, "those who walk a hundred miles are sick, and those who walk a hundred miles die." In other words, it is not appropriate to have sex before and after a long trip, and the most taboo is after a long trip.

Don't have sex when you are full after drinking, if you do, it will damage the five internal organs. If the eye disease has not healed, avoid sex, which will make people blind. It takes a hundred days to hurt your muscles and bones. If you don't have sex in 170 days, 100 days will be disabled.

The place for sex should not be cold. Avoid taking shelter from the wind and rain, avoid eating cold food, especially pears, and avoid drinking cold water after sex.
