Abstract

Although yawning is a commonly witnessed human behavior, yet it has not been taught in much detail in medical schools because, until the date, no particular physiological significance has been associated with it. It is characterized by opening up of mouth which is accompanied by a long inspiration, with a brief interruption of ventilation and followed by a short expiration. Since time immemorial, yawning has been associated with drowsiness and boredom. However, this age old belief is all set to change as the results of some newer studies have pointed out that yawning might be a way by which our body is trying to accomplish some more meaningful goals. In this review, we have tried to put together some of the important functions that have been proposed by a few authors, with the hope that this article will stimulate the interest of newer researchers in this hitherto unexplored field.
