Dear Editor,

Swimming is a water-based workout that decreases joint pain, strengthens muscles, and promotes weight loss.[1] Millions of people swim in pools around the world every day, and this exercise provides tremendous physical activity (whole-body movement) along with maintaining the body healthy. In recent years, athletes in competitive swimming spend more time and effort to enhance their performance.[2] As swimmers dislike being disrupted during training, they do not want to interrupt their workouts by peeing in the middle of it. However, according to Carly Geehr, a former member of the USA Swimming National Team, nearly all elite professional swimmers pee in the pool.[3] As said in the previous study, about one in every five American adults admitted to peeing in the pool. Olympic swimmer Michael Phelps of the United States acknowledged in 2012 that peeing in the pool is a common practice.[4] On the other hand, children are serial offenders for peeing in the pools.[5] It is sometimes more common than professional swimmers. Devlin stated that swimmers released 75 L of urine that is enough to fill a medium-sized dustbin into a large pool (about 830,000 L, one-third the size of an Olympic pool) and 30 L into a smaller pool after monitoring the amounts of the sweetener in two public pools in Canada over 3 weeks (roughly half the size of the first).[6]

Because of this poor behavior, researchers advise that all swimmers stop urinating in pools to avoid the formation of chemicals. The research discovered that uric acid, a chemical contained in urine and sweat, reacts with chlorine to create two substances: cyanogen chloride and trichloramine that swimmers inhale during the workout.[7] Although chlorine is widely believed to be the cause of the odor, it is a volatile compound produced by unintended reactions between disinfectants (such as chlorine) and organic matter in the water.[7],[8],[9] The organic matter that contributes to the formation of disinfection byproducts (DBPs) is found in body fluids such as sweat and urine (DBPs). Swimmers carry the majority of the precursors of such by-products into the pool.[9],[10],[11],[12],[13] This results in red and itchy eyes, a problem for swimmers in pools. According to the health scientists and aquatic safety experts, it's the pee, not the chlorine, which causes swimmers' eyes to become red and itchy.[14] For this reason, peeing in the pool is a bad habit that causes swimmers to engage in harmful health-related issues.

For all of these reasons, and based on scientific evidence, it is no surprise that swimmers urinate in the pool regularly and intentionally. To stop these awful behaviors, the present investigator has suggested a few concerns that could help to minimize urination in the pool. These are:

  • Install underwater cameras that can be used to track down the suspect swimmers
  • Before entering the pool, each swimmer should shower and empty their urine into the toilet
  • A social awareness program can help reduce pool urination
  • Frequent discussions with swimmers about this issue can help reduce pool peeing
  • Elite swimmers have been known to swim for more than an hour at a time. Coaches can make sure that there are breaks for urinating in the toilets
  • Place a banner, festoon, or plaque in the pool requesting that swimmers stop from peeing
  • Children can be motivated to abandon this practice by offering chocolates in the condition they have to urinate outside the pool. Later, this would be a habit when they become elite swimmers.
