I have read many articles discussing sensitivity to chlorine and how it affects some people.
It seems chloramines (a byproduct of chlorination), is the culprit, especially for those with asthma related issues. It affects some worse than others. We have many clients who are hyper sensitive to chlorine. Conditions range from skin sensitivity to sinus and asthma related issues. The numbers are way too high to suggest that there is no link. This reaffirms what I have been reading.
