Here's the low-down on potential skin problems and how to prevent them, courtesy of dermatologist Brian B. Adams, MD, MPH, FAAD, associate professor of dermatology at the University of Cincinnati and director of dermatology at the Veterans Administration Medical Center.

The Battle of Blisters

Regular runners and individuals who strength train are particularly prone to blisters, which occur because of friction between an area of your body and the equipment. Dr. Adams suggests the following: wear moisture-wicking socks, apply petroleum jelly between your sock and shoe, and wear gloves for weight lifting. The Don'ts: don't peel off your skin (if it comes off, apply petroleum jelly and bandage right away); and don't hesitate to see a dermatologist if the area around your blister becomes red, because it may be infected.

The Annoying (and Itchy!) Case of Athlete's Foot

Gyms are the perfect place for athlete's foot, or tinea pedis, to proliferate. People with athlete's foot experience itching and burning, redness and dryness, or scaly and cracked skin, and may be particularly vulnerable to toenail fungus - a case when it's time to see a dermatologist.

As far as prevention is concerned, always wear shoes and socks! Swimming pool floors and showers are notorious for breeding bacteria, so always wear aquatic shoes.

Treatment includes over-the-counter products, which Dr. Adams says are effective. If your athlete's foot just won't go away, visit your dermatologist for a prescription treatment.

Acne, Acne Everywhere

Thanks to tight-fitting clothes and gym equipment, acne mechanica can run rampant. But lucky for us, there are preventative measures. Opt for "more breathable, moisture-wicking fabrics," says Dr. Adams. He also suggests that if this isn't working, see a dermatologist who can prescribe a treatment for your acne.

Ouch! Road Rash

Especially when you're playing basketball or have close contact with exercise mats, road rash or turf burns can occur. Clean the area, cover up it with petroleum jelly and a bandage, recommends Dr. Adams. If that doesn't help and an infection occurs, make an appointment with the Doc.

A Golden Burn

Many gyms still offer indoor tanning, even though it can lead to skin cancer. So definitely avoid the tanning beds! The article also writes about the Tanning Accountability and Notification Act (TAN Act), signed by President Bush in September, which requires the FDA to review current warning labels on tanning equipment to ensure it discusses skin cancer risk and other dangers.

Other general preventative measures for sun safety include: Always wear sunscreen, whether you're running, playing sports or skiing (snow is 80% reflective); wear hats and dark clothes with SPF built-in and never run shirtless.
