Girl's Locker Room

Sweatbands can trap sweat in your pores and provide a perfect place for bacteria to grow and cause acne, so it's best not to wear them.

Loose-fitting clothes are best for physical activity. If you have acne on your arms, back, or shoulders, keeping it loose cuts down on the amount of friction on your body. Friction can make your acne worse.

Storing damp or wet workout clothes in your locker or gym bag is an invitation for fungus to grow. Hang your clothes up to dry before cramming them in your locker, and take them home at least once a week to be washed.

Be sure to take off your make-up before you work out - it will keep your pores clear and help prevent acne.

Clean out your water bottle after each time you use it - this will prevent bacteria from growing inside.

Air out your sneakers between wears to prevent athlete's foot.

When sitting in the locker room, sit on a clean towel. Damp benches can be germ-fests of bacteria and fungi that can easily be spread from person to person. If you can, get dressed first, before you sit down.

When you're in the gym, using two towels can help to cut down on the spread of bacteria - use one to wipe off the equipment before and after you use it, and one to wipe the sweat from your skin.

Wear flip-flops to walk around the locker room - those wet floors are popular hangouts for fungi looking for a foot to grab on to.

Drink plenty of water before, during, and after you are physically active to stay hydrated. In addition to keeping your body working right, it can help prevent acne by flushing out your pores.
