We often see people yawning when they are bored or lazy. Students often yawn when the lectures are boring or sometimes when people are tired they yawn to sleep. Have you ever wondered what this yawning is about and how it is contagious? Read below the details:
A Yawning is a form of expression indicating boredom or a break in thought. Sometimes it is a way of relaxing or may occur in response to a person who is yawning too. Yawning should be a process of decreasing arousal. If observed by other person and the observer arousal level becomes synchronized as a consequence the observer will also yawn.
Watching somebody taking a nap might also induce a state of declining arousal and trigger yawns. One would expect the observed yawns to be a more powerful stimulus, however, because another's yawns might precipitate the observer attending to muscular tension in the facial muscles that can be dissipated by the yawns stretch. In addition one might expect observed stretches in general to be contagious and yawns might thus be particularly obvious example of the general behavioral synchrony of interactants.
