If what Bean and KD Baby said were true that our bodies make us yawn to drawn in needed oxygen, wouldn't we yawn during exercise?
In the dictionary, yawning is said to be caused by boredom, fatigue or drowsiness. Although we do tend to yawn when bored or tired, this theory doesn't explain why Olympic athletes yawn right before they compete in their event. It's doubtful that they are bored with the world watching them. The simple truth is that even though humans have been yawning for possibly as long as they have existed, we have no clue as to why we do it, so maybe yawning is triggered by some area of the brain we have yet to discover. We do know that yawning is not limited to man. Cats, dogs, even fish yawn, which leads us back to the idea that yawning is some form of communication.

Actually, there is now evidence that yawns do NOT increase your oxygen level. No one really knows but it is suggested that it may just stretch your innards (lungs, windpipe, etc) the same way as a good long stretch does in the morning.

you yawm because your body is not getting enough oxygen and so to refresh itself and get that energy and oxygen back - you yawn.

It is when your body is low on oxygen and you need to take a big deep breath to catch up
