There are several things you can do to protect yourself from yeast infections. Most of them have to do with keeping the vaginal area drier.
- Wear underpants and pantyhose with a cotton crotch (wearing a pantiliner can also help keep you drier)
- Wear loose-fitting bottoms (shorts or pants) when you exercise, rather than tight fitting clothing
- Avoid wearing wet bathing suits or exercise clothing for long periods of time, and wash them after each use
- Don't use douches that can irritate the vagina
