Scientists said this made it the “ideal urinary marker”.Blackstock said that there was “no other explanation” for that substance to be in the pools.She noted that urine is considered sterile, and any potentially harmful bacteria that finds its way into pools is usually killed off by chlorine.Although there are moderate health risks, with a small risk of eye irritation and even respiratory problems if exposed to urine-contaminated water over a long period of time, Blackstock said that any potential harm was outweighed by the health benefits of regular exercise through swimming.There was no way, however, to estimate how many swimmers peed while in the pools, as the researchers did not monitor how many people visited the pools over the course of the three-month study.A US survey conducted in 2012 said that one in five people admitted to peeing in a swimming pool.Back in 2012, decorated Olympic swimmer Michael Phelps admitted that he and his fellow swimmers sometimes relieve themselves in the pool, while fellow US swimmer Ryan Lochte also admitted to the practice.So, what do you think? Have you ever peed in a swimming pool?
