If you work up a sweat on the job or during workouts, make sure to bathe as soon as you can. And pack a clean, dry change of clothes if you're showering away from home. Keep it dry, keep it loose. Dry yourself thoroughly after washing, using a hair dryer, if necessary, set on low, Dr. Dvorine says. And don't squeeze yourself into tight or ill-fitting clothes that might chafe against the skin between your legs or prevent air from flowing.
Ice is nice.
If you already have jock itch, soothe your savaged skin with cool compresses, Dr. Lesher says. Wrap a few ice cubes in a towel, or soak a washcloth in cool tap water, he says. Just make sure you dry off really well when you're done. While the skin is healing, stay off your feet. Providing an opportunity to let jock itch heal is a good excuse to sport your birthday suit.
