The perineum is the most susceptible part of a woman’s body. It is moist and is the channel for menstrual sex and babies, so it is very important to keep the perineum clean. The purpose of cleaning is to clean the perineum from sweat and urine stains to avoid bacterial growth, and there is no need to routinely use lotion to clean it. Secondly, it is important to develop good habits and not to wear particularly tight pants to avoid affecting the blood circulation in the perineum. Third, use cotton sanitary napkins, pads, etc. from regular manufacturers, not chemical fibers to avoid increasing the discomfort of infection.
