To put it in perspective, 1,000 hours of swimming in chlorine equates to at least one hour of swimming a day, every day, for two years. Chances are you’re not spending that much time in a pool, but still, better safe than sorry. After swimming, be sure to bathe thoroughly to wash any chlorine off your skin, wear goggles to protect your eyes, and avoid inhaling air around the pool water as much as possible.
