hard workout/breathing bronchial pain

[mimitabby]

inhaler? asthma? really? I will read the article, thanks.

edit:
I read the article. I did not experience any tightening or difficulty in breathing later, when i did a more strenuous hill. This happened not at the beginning of the exercise, but in the middle, it was the first of a series of hills.

what the article mentioned, it being a drying of the passages (which the body finds irritating) makes sense.
I wonder what can be done about it besides using inhalers!
