- Abstract
Yawning is an important prehistorical physiological mechanism that exist in animals across a variety of species. In the past 50 years, investigation of spontaneous yawning and contagious yawning has been ongoing. Several hypotheses were introduced to this field, such as the circadian hypothesis, brain-cooling hypothesis, and oxygenation hypothesis. These theories now trigger growing debates, and each theory are supported by their own evidence. Here, this review examines three popular hypotheses and reveals the arguments among them. Conversely, one novel hypothesis of mental stress seems more convincing than the other three hypotheses, and needs to be examined by empirical studies.
