A member asked:

Why does it feel like harder to breath when i get tired?

A doctor has provided 1 answer

Muscles: Breathing is a muscular activity, just like walking up stairs is. But breathing is different b/c how hard you do it varies with oxygen demand. As your muscles work harder, their oxygen needs increases & your lungs have to keep up by moving more air. Now, having said this, if you feel like this is much worse than normal, you may want to get checked out for asthma and anemia.
