Showering before swimming helps to remove dirt, sweat, lotions, and other impurities from your body, which can otherwise contribute to contamination of the water.

Always check the posted rules and regulations at the pool or beach you are visiting to ensure you're following the guidelines and helping to maintain a clean and enjoyable environment for everyone.
