Take care of your swimwear
Buy chlorine- and fade-resistant swimwear. A high spandex content is a plus, since it will help your suit keep its shape. Adding a few tablespoons full of vinegar to your wash will help neutralize chlorine, eliminate the smell, and even stop discoloration.
Keep yourself Hydrated
Carry a bottle of water and keep sipping on it. You can also drink non-alcoholic summer coolers to keep yourself hydrated and flush out toxins from your system.
Bathing in hot water will exaggerate the risks because the chemicals can be inhaled with the steam.
