Why do we sneeze?!
Question:
Why do we sneeze?
Also...why do we yawn?
its just very confusing to me.
and i'd like to know.
Answers:
we sneeze to get irritants out of our nose. When you yawn your body is asking for more oxygen. As you get tired you are breathing less and your alveoli gets smaller. Alveoli are the air sacks in your lungs. When you yawn the air rushes into your lungs and all the alveoli sacks pop open to let more oxygen circulate into your bloodstream. Also as an after thought, yawns are contagious. As you yawn watch everyone around you. they will start to yawn also.
