Healthy reflex - why yawning is good for you
Brain researchers and neurologists have been trying to get to the bottom of the phenomenon for decades, but their findings are still vague. What is clear is that we yawn about eight times a day - around 220,000 times in our lives. Italian researchers have counted. We do it for an average of six seconds. The mouth is opened four centimeters on average. But why are we yawning?
There are numerous theories about this. However, the thesis that yawning supplies the brain with additional oxygen is not true. A popular misconception that persists even though it was refuted back in the 80s: we yawn when we're tired, when we're bored. When we yawn in the morning, we stretch at the same time - get our circulation going, build up tension! Breathing in deeply stimulates blood flow to the brain. It's likely a reflex associated with changes in brain activity. In humans, yawning is related, among other things, to the sugar level in the blood. Hypoglycaemia leads to increased yawning.
Why yawning is contagious
And - yawning is contagious. Every second person has to yawn when they watch others. It is enough if we hear or even read about a hearty yawn.
If someone yawns, it suggests that they are empathetic. Because we yawn because the so-called "mirror neurons" are active in our brain. These nerve cells make us compassionate beings. Through them, we unconsciously mirror the behavior of our counterpart. Feel whether someone is sad or happy - and we adapt to it. That's exactly what we do when yawning. Studies have even shown that particularly compassionate people are particularly easily infected by yawning. So yawning does not mean: You bore me, but: I feel for you! But what is the deeper meaning behind it? Researchers believe they can be found in the animal kingdom: even lions yawn - including shortly before the hunt - show like this: It’s about to start. The group makes an appointment ... by yawning! And that's how our ancestors probably came to an understanding before they could talk to each other. So if we yawn heartily today, it's not impolite: the yawn is just in our genes!
