Nearly 97% of the runners studied said they wore running shorts and short-sleeved or sleeveless shirts.

Only 56% said they regularly use sunscreen; nearly 2% never do.

Also, long-term, high-intensity exercise suppresses the immune system, the Austrian researchers write. They note that patients who have undergone transplants and had immunosuppressive therapy have an increase in all types of skin cancers.

Reducing the Risk

Ambros-Rudolph advises runners to cover up, train when sunlight exposure is less intense, and slather on the sunscreen—in spray or lotion form. An SPF of 15 or higher is recommended.
