All this weather talk is so interesting to me. It really is the question I have been asking since the first day of my daughter's diagnosis. I even got a respitory therapist from one of my daughter's hospital vists curious...she tried to do some research but couldn't find anything! My daughters pulomonologist did say that he would never suggest any CFers to move to the Northeast which is where my husband and I are both from. My husband would move back in a second but aside from the fact I love the weather in Florida, I always say that I don't think it would be good for our daughter...he doesn't agree 100% but now I have some input from CFers about how bad cold weather is. We actually lived in England for a little while right before Gabrielle was diagnosed and that was tough on her. I know hot and humid weather is really uncomfortable for a lot of people but I do believe that the humidity helps my daughter....In 2004 when we had two hurricanes so close together and our electricity was out for awhile, and we were between breathing treatments, I would walk her up and down our street...the humidity really seemed to help! Keep up the responses...they are really interesting!! Maybe we could put a study together with all these responses!
