So here are some numbers that once and for all settle the question whether or not you should pee in the pool… 1. Your #1 mixes with chlorine in the pool and can make your eyes red and make them sting. When chlorine in the pool mixes with pee, chemicals called chloramines are produced. Chloramines—yep, chlorine mixed with pee—can irritate swimmers’ eyes and make them red and make them sting. Chlorine alone at levels typically found in pools does not irritate swimmers’ eyes. 2. Your #1 mixes with chlorine in the pool and can make you cough, wheeze, and have shortness of breath. That “chlorine” smell at some indoor pools isn’t caused by chlorine. It’s caused by chloramines that evaporate from the water and into the air. Airborne chloramines can irritate the lungs and cause coughing, wheezing, and shortness of breath. Healthy pools don’t have a strong chemical smell. 3. Your #1 uses up the chlorine that kills germs. Chlorine breaks down pee when they mix. That means there’s less chlorine in the pool to kill germs like the ones that come from #2. 4. It’s just gross swimming in your #1. Who wants to swim in their own pee—or even worse—in someone else’s pee? Need more reasons why not to pee in the pool? 665 people had red, stinging eyes and other symptoms and a young child ended up in the pediatric ICU because of chloramines in indoor pools. As the old saying goes…We don’t swim in your toilet, so don’t pee (or poop) in our pool.
