I also have asthma and high humidity seems to bother me more than anything else. I also have allergies and in the Spring and Fall I'm bothered, but high humidity has been bothering me all summer. I walk outside and feel like my lungs just close up. I can't breathe..... I haven't been able to ride outside much this summer because of the high humidity (Northeast). I'm hoping for a huge thunderstorm to bring in some low humidity. Does humidity bother anyone else out there?
