Does the chlorine in pools aggravate asthma? I seem to get asthma attacks more when swimming than when doing other exercise.

In brief: Chlorine in pools

Yes, chlorine in pools can definitely be a chemical irritant not only for asthma, but also for nasal and sinus conditions and can lead to sinusitis that also can trigger asthma.
So it's potentially a problem two ways. A lot of pools are being converted to salt water mixes that require a lot fewer chemicals. If you own the pool, you could check into that. It never hurts to bring up the possibility.

In brief: Yes

The chlorine in pools is released as chlorine gas as it evaporates from the pool.
The first few inches above the water has the highest concentration & it is more prevalent on sunny days. Exposure can trigger wheezing in a non-asthma patients at high levels.Sometimes swimming in indoor pools would improve your problem, but this is likely a persistent issue.
