Oscitation
Oscitation refers to the act or instance of yawning. It is a physiological response characterized by the involuntary gaping of the mouth, often accompanied by deep inhalation and slow exhalation. This reflex typically occurs due to fatigue, boredom, drowsiness, or the need for increased oxygen intake. The function of oscitation is not completely understood, but current theories involve thermoregulation, the arousal of the brain, and the release of neurotransmitters. It's a common human behavior seen in a range of situations.
