Yawning: A Biological and Social Behaviour
We've all done it - let out a big yawn, maybe becau we're bored or tired, or maybe just eing others yawn can t us off. But is this biological function contagious, and what's the reason behind it?
Although many people think we yawn to take in more oxygen, rearch suggests that there is no clear biological reason. The latest theory suggests that yawning cools the brain down and prevents it from overheating like a laptop fan. This may explain why we yawn more in warm temperatures.
Interestingly, we tend to yawn more when we're exhausted and ready for a nap. Furthermore, once we start, we can't stop until the yawn runs its cour!
But what makes yawning particularly compelling is that it's highly contagious. Rearch by John Drury, a Susx University rearcher, found that yawning is an automatic respon and that dogs, animals, and humans all yawn when they e others yawning, whether they want to or not. Drury also discovered that our social group and cloness to tho around us linked to our propensity to initiate the behavior.
Another study conducted by the University of Nottingham confirmed that yawning is contagious between humans, and our inability to resist yawning when we obrve others is limited. They further found that when volunteers were told they couldn't yawn, their urge to do so incread drastically. Studies have discovered that electrical stimulation can increa people's desire to yawn, offering potential benefits for treating other neurological conditions, such as Tourette's, which relates to the same area of the brain.
In conclusion, yawning remains something mysterious and intriguing, creeping up on us even when we are not particularly tired. So, if you suddenly feel like yawning while reading this article, remember that it's normal!
