Douching is the method of cleaning or washing the vagina with fluids like water and chemicals. About 20% of women aged 15-44 douche. According to the Department of Health and Human Services, douching is linked to vaginal irritation, vaginal dryness, infertility, STDs, and vaginal infections like yeast infection, bacterial vaginosis, and pelvic inflammatory diseases. Women who douche are five times more likely to have a vaginal infection than women who do not douche. Vaginal sprays and other vaginal products, which are meant to be healthy, can sometimes contain harmful chemicals that cause yeast infection and other types of vaginitis. Avoid douching and using sprays on your vagina to reduce the risk of yeast infections.
