Arizona is known to be one of the most comfortable places for people with breathing problems to live, because of the dry air. A really nice place in Arizona is Scottsdale! There are a lot of different niceScottsdale Homes for sale. Everyone says places like Florida are paradise, but they often forget to factor in the humidity, which is what makes you all sweaty and gross when it is hot, plus it is horrible for any breathing problems that you may have. Arizona is so much better for that!
