June 22, 2018
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.
