Watersports can cause a handful of ear problems, including infections, swimmers/surfers ear, exostosis and eardrum perforation. These issues, including infection, can occur even in a chlorinated pool.
Both surfer's ear and swimmer's ear is primarily caused by prolonged exposure to cold water or wind, but the condition can be caused by warm water as well. The easiest solution is to wear swimming earplugs, which helps keep water out of your ears and prevents water-related ear infections, ear pain, “swimmer’s ear” and many more problems.
