- According to the Centers for Disease Control and Prevention (CDC), urine, not chlorine, is responsible for red eyes after swimming in pools.
- It’s reported that contaminants in pools (such as urine and sweat) bind to chlorine, resulting in irritants which cause your eyes to get red and sting.
- This situation is exacerbated in indoor pools where there is poor air turnover.
- Worryingly, the CDC advised that a strong chlorine smell is caused by a high-level of these irritants and is not indicative of a clean pool.
- According to the CDC, optimal chlorine level is 1 to 3ppm and that the situation is managed simply: use the pool to swim, the restroom to pee and the showers to wash up before getting in the pool.
- FYI, a survey by the Water Quality and Healthy Council found that almost 1 in 5 Americans admit to relieving themselves in pools!
