Surfers are very much exposed to skin cancer. UV rays, sand and water reflection are responsible for severe skin damages. Irreversible problems may appear in as little as 15 minutes of sunlight exposure.
Check out these pictures I took from Crocodile Rock in Boracay Philippines. Really good dive site for Boracay. Alot of life there that I thought would be gone due to negligence from the locals. I have been to this site in about a year. One of my top fav sites.
