Nor did it seem to discount all environment, social and personal factors. Several years ago, there was a study that came to the conclusion that asthmatics who were athletic were less likely to use their medications as directed when they are participating in sports. This article also doesn&#39;t dismiss the simple explanation used for years that exercise can be a factor in producing an asthma incident. I don&#39;t know this but is chlorine a protein? I think it isn&#39;t. I think the product that is produced when individuals urinate in a chlorinated pool is when there is a protein. Chemist help. You can&#39;t be allergic to something if it isn&#39;t a protein. Several years ago there was a great study published in Lancet that stated that asthmatic swimmers have changes in their bronchial passages that neither nonasthmatic swimmers nor ashtmatic nonswimmers don&#39;t have.<div style="clear:both;"></div>https://community.usms.org/thread/105347?ContentTypeID=1Fri, 26 Sep 2008 10:39:44 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:c3c88ddd-e9a9-43ad-9299-92a91e3c0c1eswimcati breath worse in indoor pools because of no air circulation. i used to swim outdoors in fl. and breathed a little better. the indoor pools have mold which aggravates most asthmatics(let me also add outdoor ones probably do too). i breath the best in the ocean. must be the salt water. how about bromine pools?:<div style="clear:both;"></div>https://community.usms.org/thread/105318?ContentTypeID=1Thu, 25 Sep 2008 03:19:32 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:0420cb23-6446-4144-a16c-e4c6581a8c57elise526I am curious to know, however, if the benefits of swimming for asthmatics outweigh the costs of increased exposure to chlorine. I was born with asthma and as long as I was swimming on a regular basis, did not need an inhaler. It was when I stopped swimming that I seemed to need the inhaler more. Obviously, being around chlorine for the long-term is not good as I see more and more masters swimmers being diagnosed in their thirties with asthma. I do, however, wonder what my quality of life as an asthmatic would have during my pre-teen and teen years had I not been swimming.<div style="clear:both;"></div>
