According to new study Chlorinated pools may lead to cancer

Many of our oldest members have probably swum in chlorinated pools for many years. Of course we don't know their medical histories, but any of you who have attended a large Masters meet will agree that these members all look fantastic! I got curious and just ran some numbers. Of our 2010 members as of today, here's how many we have in our upper age groups: 80-84: 306 85-89: 125 90-94: 43 95-99: 6 100+: 1

USMS seniors look healthier than non-swimmer seniors, but i don't think this observation proves anything. we all know of many that have had to stop swimming regularly due to health issues as well. i am very distressed by all the inhalers i see on deck during any age group practice session. again, not science, just an observation. i also know that the air feels quite "heavy" around a lot of pools i've visited.

Chlorinated drinking water?? Methane gas in drinking water?? What is safe to drink. Margaritas?? We use ice cubes made of chlorinated water.

I'm pretty sure that I saw that posting on internet forums can be deadly for your hea

as already noted, the risk (if any) is trivial compared to the benefits of swimming, so....keep swimming, don't worry about it regarding the "new" study (part of a trilogy published September 2010).... From the study... "Swimming is not associated with DNA damage." "Levels of disinfectant byproduducts in swimming pool water are not necessarily higher than those in drinking water." "brominated DBPs are generally more genotoxic and carcinogenic than chlorinated DBPs" (DBP = disinfectant byproducts) Chlorination is not the problem according to the study (regarding statistically significant changes). Bromination may be. Higher levels of exhaled brominated trihalomethanes were associated with increased numbers of micronucleated lymphocytes, but not in changes in micronucleated urinary tract lining cells. 'Urine mutagenicity" increased in association with higher levels of exhaled bromoform (determined by mutagenic effect of urine samples on the bacteria Salmonella). May Be! Increasing cancer risk from indoor pools and absorption through the skin and lungs is HIGHLY speculative. Direct data does not exist...ie, data showing an increased cancer risk in cancer rates (vs a suspected biomarker effect from brominated compounds). Study design, by the way, involved pre-swimming testing vs post-swimming testing, wherein swimming meant 40 minutes of undefined swimming in an indoor pool in Barcelona, Spain in 2007. Doing jumping jacks, pushups and situps, or merely sitting, near the pool for 40 minutes may have produced similar results!

During the polio epidemic Winnipeg 1953 the pool was loaded with chlorine. The Canadian swimming Champioships were held there. There was so much chlorine in the pool your eyes turned red when you went into the pool area.

I remember years ago a friend told me "Lui, I think it's cool that you swim but I would worry about the chlorine. It might cause cancer". While he was telling me that he was smoking a cigarette:D

Even the rich and famous are dying of cancer at young ages; which tells me that no amount of money or treatments thrown at fighting the disease will necessarily stop its progression. My parents are true baby boomers; my dad has dealt with bouts of pancreatic and skin cancer already - and at least two of my uncles have had various cancers they have or are getting treated for. Might I add that all three of these men live healthy active lifestyles (weight under control, non-smokers, healthy eaters). So tell me where the logic in the whole thing is?

ION pools are the best to swim in, no chlorine
