Hi pd this is such a great question. I have practiced yoga and breathing for many years, and have serious lung damage. I would not be alive if I had not done so - controlling your breathing helps calm you, which allows more healing to take place as stress of course has a terrible effect on the body., by doing yoga in general, major organs receive more blood flow, circulation, and oxygen, which also helps "clean up" the lungs. I don't know what area you live in but I would see what you can find through pulmonary therapy. You should be able to find basic yoga classes specifically for disability. I would learn basic yoga first and enjoy the great peace and calm that comes with that, then learn more of yogic breathing! Please update sometime I would really love to know what direction you took! Yoga is a very powerful healing modality! It meets you where you are at. With 'blessings and love. : )
