Peeing in chlorine water can create chemicals that irritate eyes, causing them to sting in swimming pools.

Infact verdict: Mostly True (74/100).

Peeing in pools can create chemicals called chloramines that irritate eyes, as supported by multiple sources. These chloramines form when chlorine reacts with substances in urine and sweat, reducing the effectiveness of chlorine as a disinfectant. This explains why swimming pools can cause eye irritation. Overall, the evidence confirms the accuracy of the claims that urine in pools contributes to eye irritation through chemical reactions.
