Why swimming can be a health hazard?

The DANGER of Swimming

While swimming is one of the BEST exercises for Fitness, many suffer the exposure of Chloroamines(Combined Chlorine)

Chloroamines is formed when Chlorine (dosed into the pool water for disinfection) reacts with organic compounds like ammonia(from urine), sweat and sunbath lotion.

Almost all pools in Malaysia are not tested for presence and level of Combined Chlorine (and Chloroamines -THM)

“ Chlorine is really good at killing microbes in swimming pools. Over the years, though, scientists have become concerned about its possible health effects. In water, chlorine reacts with sweat, urine, skin cells and other organic materials to produce all sorts of chemical byproducts. In animal studies, some of those chemicals have been linked with asthma and bladder cancer. “ http://news.discovery.com/human/chlo…ng-cancer.html

“Chloramines, also known as combined chlorine, are formed when free chlorine reacts with ammonia like compounds called amines. Chloramines are poor disinfectants and greatly reduce the disinfection power of free chlorine, irritate mucous membranes, cause eye stinging and red eyes and irritate respiratory systems.”

“adverse health effects-skin reactions (rashes, welts, blistering, dry skin, cracking, chapping, peeling, bleeding, burning sensations, scarring), respiratory symptoms (sneezing, wheezing, coughing, sinus/nasal congestion, asthma-like conditions), and digestive disorders (acid reflux and symptoms similar to IBS) plus dry eye and dry mouth.”


Of 128 individuals interviewed, 32 met the case definition. Common symptoms among case patients were cough (84%), eye irritation (78%) and rash (34%). Illness was associated with entering the pool area [odds ratio (OR) 19.9; 95% confidence interval (CI) 2.3–172], but more strongly with swimming (OR 72.0; 95% CI 9.1–568). Pool chloramine levels on 6 October 2002 were 0.7ppm (optimal level=0ppm; state maximum=0.5ppm). The pool operator lacked formal training in pool maintenance.”


So, it’s important to swim in properly treated pools…technically, pool with Drinking Water Quality
