Michael Phelps' stellar performance at the Beijing Olympics inspired countless kids and adults to jump into the pool with visions of gold medal glory -- or simple fitness -- on their minds.

But some may be putting their lungs at risk, according to emerging research that suggests chlorine in swimming pools may be linked to childhood asthma.

A group of researchers in Belgium that previously reported a link between indoor swimming pools and asthma have extended their research to outdoor pools as well, according to the London Telegraph.

The study looked at 847 students with an average age of 15. Those that had swum for the equivalent of one hour a week in an outdoor pool for 10 years were five times more likely to have asthma symptoms. Those with other propensities for allergic reactions were 10 times more likely.

If you're installing a pool, consider a natural pool.
