Avoid Swimming Pools if You Have Allergies or Asthma

Swimming in a chlorinated pool may boost the odds that a child susceptible to asthma & allergies will develop these problems. Chlorinated pools irritate the airways of swimmers, exerting a strong additive effect on the development of asthma and respiratory allergies such as hay fever & allergic rhinitis. The impact of chlorinated pools on the respiratory health of children & adolescents appears to be much more important -- at least by a factor of 5 -- than that associated with second hand smoke.
