Answers:
The Physiological Theory -- Our bodies induce yawning to drawn in more oxygen or remove a build-up of carbon dioxide!. This theory helps explain why we yawn in groups!. Larger groups produce more carbon dioxide, which means our bodies would act to draw in more oxygen and get rid of the excess carbon dioxide!. However, if our bodies make us yawn to drawn in needed oxygen, wouldn't we yawn during exercise!? Robert Provine, a psychologist at the University of Maryland, Baltimore County, and a leading expert on yawning, has tested this theory!. Giving people additional oxygen didn't decrease yawning and decreasing the amount of carbon dioxide in a subject's environment also didn't prevent yawning!.
The Evolution Theory -- Some think that yawning is something that began with our ancestors, who used yawning to show their teeth and intimidate others!. An offshoot of this theory is the idea that yawning developed from early man as a signal for us to change activities!.
The Boredom Theory -- 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!.Www@Answer-Health@Com
