On a sweltering hot day, nothing feels better than jumping into a nice cool pool. And for fitness, nothing beats swimming laps for a full body workout without putting strain on your joints. Or perhaps it’s your kids or grandkids whose summer recreation includes a dip in a public swimming pool, or a private membership-based pool.
But for you and your family’s health, you may want to rethink jumping into a pool; if you don’t want to spend the next week sick. Studies show that poop – yes poop – and other bacteria are swimming in the pool with you. You won’t see it floating around but it’s there, making people sick!
Centers for Disease Control and Prevention reported, after taking 161 water samples from metro-Atlanta public pools in the summer of 2012, 58% contained E. coli bacteria, even though these pools contained chlorine. Chlorine kills bacteria in the water, but slowly. Bacteria can survive for hours, even days, even in a properly maintained pool.
It’s not just swimming pools to be on the lookout for but also wading pools, water parks, misters, public fountains, whirlpools and hot tubs. Germs can enter your body by inhalation, swallowing or merely having contact with your skin.
A study by the Water and Health Council reported that seven in ten people don’t shower as recommended before entering the pool. One in five people urinate in the pool. That fact alone leaves us feeling quite uneasy about entering these popular summer oases at all.
So what are the risks…
Chemicals in the water or their evaporation can also cause recreational water illnesses.
Diarrhea is the most common illness, usually caused by Cryptosporidium (Crypto). Crypto can stay alive in pools for days because it’s tolerant to chlorine and is a leading cause of diarrhea and prolonged diarrhea, lasting two to three weeks.
Norwalk Virus can cause diarrhea and vomiting.
Naegleriasis and Acanthamoebiases infect the eyes and skin.
Pseudomonas causes swimmer’s ear and skin rashes.
During a 2010 study, one in eight public pools was closed after inspection found serious code violations. The most common violators were kiddie pools, wading pools and water play areas. Swimming pool codes aren’t federally regulated, but are developed and enforced by state and local public health agencies.
Just because a pool has a strong chlorine smell don’t assume it’s clean – in some cases it means just the opposite – it’s extremely dirty! Pools should be monitored frequently and in some places are tested hourly, especially when the pool is full.
