There are two primary reasons that we yawn. The first is to cool the brain says Andrew Gallup, a researcher in the Department of Biology at Binghamton University. According to a study conducted by Mr. Gallup brain temperature was a controllable cause of yawning. The second reason is to regulate Carbon Dioxide levels. Yawning is great way for the brain to ex hail large levels of retained Carbon Dioxide. Carbon Dioxide represents an acid in the blood stream and is manipulated to maintain normal Ph levels.
Hope that helps.
