Mortman also emphasizes the importance of physical activity. Staying active can be one of the best things you can do to maintain and improve your lung function. Simply going for a walk outside can help those air sacs in your lungs stay open.

Animal studies have found that exposure to filtered air decreases mucus production in the lungs. Mucus can block those smaller airways and make it harder to get oxygen. Before spending time outside, check your local weather station for air quality reports. According to the American Lung Association , staying hydrated is important for lung health. Drinking warm beverages , like tea, broth, or even just hot water, may cause thinning of mucus, making it easier to clear from your airways.

Many ex-smokers feel a sudden letdown once they get beyond the three-month mark as the physical improvements taper off while the cigarette cravings persist albeit at a lesser rate.
