Women's private parts avoid cleaning female genitalia every day, instead of "washing is healthier!" as advertised. "The female genitalia has a special physiological and anatomical structure. Because labia majora and labia majora are closed, vulva can prevent foreign pathogens from invading vagina, and vagina has self-cleaning function. There are many kinds of flora in vagina, among which lactic acid bacteria are dominant, which can maintain the acidic environment in vagina, inhibit the growth of other pathogenic bacteria, balance the flora in vagina and maintain vaginal hygiene. Daily vaginal irrigation will disturb the balance of vaginal flora and the change of pH value, which is beneficial to the growth of pathogenic bacteria and the occurrence of vaginitis. Poor sanitation is not the only cause of vaginitis. People with low immunity, diabetes, pregnancy and extensive use of antibiotics are also prone to vulvitis and vaginitis. Public places such as baths, swimming pools and hot springs are also one of the sources of pathogens. In addition, the health status of sexual partners can not be ignored, and multiple sexual partners are also prone to sexually transmitted diseases.
