Oak, I actually use one of those My dryer has never worked and in the winter I hang the clothes in the kitchen. I don't think the extra moisture gets upstairs though...and I loathe doing (folding) laundry so I avoid it at all costs!

However, the dryer not working makes me reluctant to wash my comforter, but that's a good idea. I didn't think of that.

I'm going to start keeping track of this for a week or two. I think it's worse at night after I run. This morning I could still breathe through my nose but instead of running yesterday, I spent an hour in my nice (nasty) humid hot gym.

Thanks everyone!
