Thank you for your question and sharing your story. I’m sorry to hear you had a rough winter. It certainly was a rough (and long) one for all of us, especially those with respiratory conditions. In general, I am a big advocate of exercise when PAH is well-treated and the patient is seeing a PH specialist regularly. Many PAH physicians agree that not only is exercise not harmful but that it may even be beneficial. That said, it is always important to talk to your PH specialist before starting an exercise program of any kind, and it is important to not exercise beyond the point where you have symptoms (light-headedness, chest pain, severe shortness of breath). In patients who are starting out, pulmonary rehabilitation programs can be helpful in teaching safe limits of exercise as well as well-rounded programs. Plus, when you can do it, exercise is a part of actively taking an element of quality of life back. Good luck!
