My wife and I live here in the foothills of Yuma half of the year in fall and winter. The rest of the time is in Washington East of Tacoma in Puyallup. The winter cold on my lungs is hard to handle. The extreme heat of 90 + degrees in Yuma is often suffocating. I was diagnosed with COPD in 2004. I am a patient of the VA and am on Symbicort, nighttime oxygen as needed, and use a nebulizer twice a day.
