The Asthma Connection

Adding to the problem, athletes may be more prone to asthma than others. For example, 12 percent of high school athletes in an Annals of Allergies, Asthma & Immunology study had asthma, and one in six U.S. Olympic athletes at the 1998 Winter Games suffered. By comparison, asthma affects just one in 15 in the general population. One possible reason: Asthma can be induced by strenuous exercise.

"Asthma is an inflammatory disease, so the airways are chronically irritated," says Norman Edelman, MD, chief medical officer for the American Lung Association. "Even when asthma is under control, ozone and particle pollution can exacerbate inflammation and bring on an attack." Worse, pollutants like ozone narrow airways, magnifying the effects of any other allergens, and an asthmatic's pollution threshold is lower than that of the average adult.

Are they trying to help gyms membership rates go up with this article? I'm sure there are health dangers in there too, with all the chlorine, cleaning chemicals, and off-gassing!

What a load of rubbish, yes running in a busy street is probably not the best for you, but Im sure that running and walking in parks ect is doing more good to you than harm, if you listened to every story like this you would end up not being able to do anything as it "might be bad for you"
