Here's an interesting NYT article on exercising in the cold:

Interestingly, I just had a conversation with a friend who said that her doctor has advised her against exercising in less than 50 degree weather because she apparently has allergy-induced (not exercise-induced) asthma. I'd never heard her complain of having asthma before but whatever.....The point I took from the article is that that if dry weather, not cold weather, restricts airways, then people with asthma should presumably be able to exercise in cold, damp weather. Is that true?

Temps are supposed to be below zero on Sunday and I have to admit that I intend to forego running outside.
