I was diagnosed with EIA two years ago, at the age of 53. Never had any trouble prior to that. I only have a problem in cold weather. In the winter where I live, morning temps are usually in the 20s, sometimes dropping into the single digits. I bike commute year-round, so that's a consideration. I use a FloVent inhaler, which helps a lot. Sometimes, though, I just forget to take it with me. Then I'm coughing for a few hours at work. Mostly this is just a nuisance. I also find that the inhaler, which is advertised as holding 100 doses, only really holds 40-50.

My daughter, who is a cross-country runner, has a more serious asthma condition. She uses a steroidal asthma inhaler morning and evening, and another inhaler at the time of exercise as well. Even this does not work entirely. She gets frustrated with the insufficient efficacy, but keeps on doing what she's doing. Her asthma also is only an issue in the fall-winter.
