Chlorine damages the lungs?

Athletes-swimmers often get pneumonia similar to that for which it passed to patients with asthma, and also exhibit increased sensitivity to allergens (such as animal dander). Scientists believe that prolonged exposure to chlorine and products that contain it, contributes to the changes in the lungs.

Researchers from France and Canada compared lung tissue (and have done a breath test) in 23 Canadian swimmers,

whose average age was 21y.o., with 10 people suffering from mild asthma and 10 healthy subjects who did not show any allergies (the same age). Samplestissue and tests performed outside the swimming season.

A team of researchers, led by Valérie Bougault of Lille 2 University of Health and Law in France, found that tissue samples taken from the lungs of swimmers were almost six times more immune cells associated with asthma and allergies

than in the lung tissue of healthy subjects (like the number found in patients with mild asthma). U swimmers and asthmatics also noted signs of scarring in the lungs (which was not noticed in healthy people who can not swim). 

Alfred Bernard, a toxicologist at the Catholic University of Louvain in Brussels (Belgium), who was not involved in the study,

noted in an email sent to Reuters Health: "This study is the first show evidence of damage to the respiratory tract caused by baths in chlorinated water. "

Do changes in the lung caused by chlorine can lead to asthma ? Scientists are not sure.
