The vulva is the first line of defense to protect the reproductive tract from infection. Due to long-term humidity, sweating when walking, or menstrual blood accumulation, there are usually many secretions gathered in the folds and gaps of the vulva. Cleaning the vulva is to prevent the accumulation and pollution of secretions, sweat, urine and feces, resulting in odor and infection.

2. physiological period

During the menstrual period of women, hormones dropped to the lowest level in a month. Menstrual blood can make the pH value of weak acid in vagina alkaline, reduce the resistance to bacteria and be susceptible to infection. In addition, dry menstrual blood and sebum are easy to accumulate in folds, which is easy to cause odor. At this time, professional nursing is particularly important.

The skin of private parts is unique in that it is covered by a thin stratum corneum, which contains a large number of hair follicles, making it easier for microorganisms and other substances to penetrate into the skin.

After intimate behavior, acid, alkali and body fluids fuse, and the balance of pH of skin in private parts is broken, which may also cause minor injuries due to friction. At this time, cleaning and repair are particularly important to prevent bacterial infection.
