Exercise-related rashes are usually caused when certain areas of the skin rub against each other or against something the exerciser is wearing. Common places for rashes are the under arms, between the thighs where the thighs may rub, between the buttocks and in the groin area. To minimize the likelihood of getting a rash, a person can apply a product to those areas that are rash prone to reduce friction. Many athletes use products such as petroleum jelly and other preparations that can be found at your local sporting goods store, usually in the running or biking sections. Also helpful are some form-fitting undergarments that help reduce friction in these areas.

To prevent exercise related rashes it is important to follow safe hygiene practices. Wipe down exercise equipment before and after use. Avoid wearing overly revealing clothing such as tank tops and mid-drifts. Opt for workout apparel that covers your body, such as short or long sleeve shirts, to keep your skin from contacting gym equipment benches and pads. Shower immediately following exercise. Hot sweaty environments are ideal for microbes to grow. If you do get a rash, opt for an over the counter topical ointment. If the rash continues to grow, make an appointment with a dermatologist.

Many people complain of skin rashes after exercise, especially if their thighs rub together or clothing irritates the skin. This bright red patch is nothing more than inflamed skin or dermatitis.
Sometimes the rash occurs when wetness is trapped next to the skin as occurs when one exercises in hot, humid conditions. The warm moist area provides the perfect environment for microbes to grow, resulting in an irritation rash or a yeast rash. Yeast rashes that are normally found on the skin can take over and grow out of control, leaving the skin reddish, puffy, and slightly warm to touch.
The best way to avoid dealing with irritating rashes is to take precautions ahead of time. For instance, remove sweaty clothing immediately after exercise, and then rinse the sweat and bacteria off the skin with a cool shower. Get out of the wet bathing suit immediately to avoid a yeast infection or itchy rash.
If a rash does appear, try a cream that contains zinc oxide, bisabolol, allantoin, or petrolatum to help protect the skin and boost healing. These products should be gently applied directly on clean skin to help it heal. Also, avoid the use of powders and cornstarch as these stick to the skin, forming the perfect breeding ground for bacteria to grow.
