Good To Know: Yawning is Not Just a Symptom of Being Tired

Have you ever been the victim of someone’s infectious yawning? Research has shown that yawning actually isn’t infectious. It is simply the imitation of others – it activates parts of the brain that deal with motor imitation, empathy, and social behaviour. A yawn generally shows that we are tired or sleepy, but it can mean something else as well.

According to experts, yawning is an involuntary action that results the inhaling of a (too) large amount of air through the mouth, which is nearly unstoppable due to muscle contraction. Although this has been studied extensively, it is not entirely sure why people, and animals, yawn. We yawn at different moments: it can be caused by sleep, fatigue, boredom, stress, etc.
