nope. sorry, not quite unique. I have exercise, smoke (cigarettes, not campfire), and other allergen-induced asthma. Cold temperatures seems to really help it, as long as I keep my core warm, I can breath cold air all the time and it doesn't affect me. But if it's too hot, say over 80, I can't run, but I can keep up biking somewhat. I don't exert in really cold temperatures, though, because it still does damage to your lungs (inflammation) that can badly affect your breathing down the road. (no pun intended)

I have an inhaler that I use before working out, and sometimes I carry it biking, but when I'm out there and get really warmed up it doesn't seem to be as much of an issue.
