So, because I have CF something that is very difficult to do is run/exercise. People with CF have mucus in their lungs and their lungs struggle to breathe as well as other people. I find myself gasping for air as I run and coughing a lot, especially when I’m not feeling the best. Although I am able to run 5Ks I still struggle. I do more of a jog than a run and I always carry my inhaler (xopenex) with me in case I need it. I also always try to drink plenty of water before I run, and even though this is a grosser aspect to CF, I do it to help thin the mucus in my lungs and make it easier to cough up.
