Reducing stress, getting enough sleep and a nutritious diet are also good ways to take care of yourself and prevent future flare-ups of vulvitis.
Other ways to prevent vulvitis include wearing white cotton underpants, practicing good hygiene, and avoiding vaginal douches. Vaginal sprays and powders should also be avoided, as should tight pants. Unless you're in a long-term monogamous relationship, always use condoms during sexual activities to reduce your risk of vulvitis, STDs, and other vaginal infections.
