Have you ever fallen victim to someone else's contagious yawning? In fact, according to studies, yawning is not contagious. It simply brings up the habit to imitate others – it activates motor imitation, empathy, and social behavior parts of the brain. A yawn usually shows that we are tired or sleepy, but can also have other meanings.
According to experts, yawning is an involuntary act that results in inhaling a large amount of air through the mouth, which is almost impossible to stop due to muscle contraction.
