How do your lungs change as you get older?
As you age, the lung tissue that helps keep your airways open can lose elasticity, which means they cannot expand or contract as easily as when you were younger. The muscles your body uses for breathing may get smaller or weaker, and your spine can curve more, leaving less space for your lungs to expand. It can take longer to clear mucus and particles from your airways. It can also become harder to cough. These changes can make it harder to breathe during physical activity as you get older.
