Yawn

A reflex action characterized by a deep inhalation of air followed by an exhalation, often accompanied by the opening of the mouth wide. It's a physiological response usually triggered by tiredness, boredom, sleepiness, hunger, stress, or even simply seeing others yawn. The exact physiological mechanism isn't fully understood, but it may serve to cool the brain, increase oxygen levels, or act as a social signal of fatigue or empathy. Yawns are contagious, meaning witnessing or reading about yawning can often trigger the reflex. Furthermore, yawning can sometimes signal an underlying medical condition, such as excessive sleepiness, which can require medical attention. The act of yawning can also be used metaphorically to describe feelings of boredom, disinterest, or a lack of enthusiasm.
