Asthma May Be More Prevalent In Those That Swim Indoors!

 "Exposure to swimming pool chemicals may cause asthma in those with allergies. Unfortunately, how indoor swimming effects those with allergies has demonstrated conflicting results. In a new study, the relationship of indoor swimming in children that were sensitized and those that were nonsensitized was examined. In addition to a survey, participants also participated in a 10-allergan skin test. Participants with asthma were considered to be physician-diagnosed for asthma or those that used asthma medication in the prior 12 months. Swimming pool use included those who attended once or more than once in a week. The results of the study showed that asthma was more prevalent in the children using an indoor pool more than once a week. This finding was independent of many variables including sex and parental smoking, etc. Interestingly, there was no association of pool use and wheeze, rhinitis, sensitization, and eczema. The author's concluded there is support for the association of indoor pool use and asthma."
