How long will it take you to read this blog before yawning? Fingers crossed you’ll make it to the end, but yawning is one of those strange things that for some reason, when we see or hear someone do it, we can’t help but yawn ourselves.
There is something that is so contagious about yawning, but what goes on in our brains that makes us yawn?
Yawning is something that we can’t control; it is an involuntary reflex that is our brain’s way of telling us that our body craves more oxygen. When we feel tired, our breathing naturally slows down, which means that our bodies take in less oxygen, causing us to yawn.
ScienceDirect also suggests that yawning may be our body’s way of trying to keep us cool, as by regulating our body’s temperature, it can prevent our brains from overheating.
So where does contagious yawning come in?
If you’ve ever been around someone and they’ve yawned, it’s likely that you’ve yawned soon after. Some people believe that yawning is contagious because of neurological stimulation, but others believe it is simply down to being empathetic.
Our empathetic traits and contagious yawning first start when we are around five years old, which is when we are said to develop the ability to read emotions.
Contagious yawning is caused by mirror neurons that are said to stimulate the brain into copying something that we already see, so if someone is close to us and they yawn, our first instinct is to yawn too.
Other interesting theories suggest that contagious yawning is a result of unconscious behaviour called ‘herding’. It is considered an involuntary way of us communicating with each other, like a flock of birds do when they take flight at the same time.
