Is it possible to yawn on command?
You cannot truly yawn on command, he writes in American Scientist. Yawns occur either spontaneously or as a contagious response to an observed yawn. Intense self-awareness, as when you are being observed or even suspect that you may be observed, inhibits yawning.
What triggers you to yawn?
Yawning is a mostly involuntary process of opening the mouth and breathing in deeply, filling the lungs with air. It’s a very natural response to being tired. In fact, yawning is usually triggered by sleepiness or fatigue. Some yawns are short, and some last for several seconds before an open-mouthed exhale.
Can you force yourself to yawn?
To make yourself yawn, open your mouth wide like you’re going to yawn, even if you don’t feel a yawn coming on. Just getting in position to yawn can be enough to prompt an actual yawn to form! Next, tighten the muscles at the back of your throat and take a deep breath through your mouth.
Can people yawn on purpose?
One is that when we are bored or tired, we just don’t breathe as deeply as we usually do. As this theory goes, our bodies take in less oxygen because our breathing has slowed. Therefore, yawning helps us bring more oxygen into the blood and move more carbon dioxide out of the blood.
