Over the past 1 1/2 years I've noticed a corrilation between exercising and my sarcoidosis improving. It makes sense though. The exercise (walking) keeps my lungs expanded consistently, which in turns prohibits more granulomas from forming. Consistent lung expansion helps me breathe easier without the use of my inhaler. Daily I walk at least 30 minutes at approximatel 2.5 to 3.0 mph on the treadmill. I know that speed doesn't sound very fast, but that's not bad considering not only I have pulmonary sarcoidosis, but also had a hip replacement. You go girl!!
