I have had COPD since 2006. It has progressed to end stage. Long ago I found that by using a floor fan in my bedroom, and other places, it helps me get my breath. I do not know why this is true, but it is. I wanted to see if anyone else has found this...and, let others know that using a fan MAY help them as it does me. No, it does not take away my problem with breathing - it just helps me with exasperations and I run the fan when sleeping or napping...it does help me.
BTW: my condition is so bad that I have to take breathing treatments 6 times a day, every day.
