Do competitive swimmers pee in the pool at practice?

Yes, competitive swimmers often do pee in the pool during practice. The combination of cold water and the physical exertion of swimming can trigger the need to urinate. While many swimmers try to avoid it, the reality is that it can happen, especially in lengthy training sessions. Pool chemicals, particularly chlorine, help mitigate any potential hygiene issues, but it's generally considered a common, albeit unspoken, occurrence.
