Yawn, the reason revealed: that’s why it’s contagious

Something that we practice regularly, when we are tired or bored, both humans and chimps do. Here’s what it is.

It is a very natural gesture, the yawn. But the question arises, why do we often yawn when we see this gesture done?

Surely it is a need for oxygen, as the lungs enlarge. When we are tired, fatigued and therefore have a lack of oxygen, we yawn.

What happens when we see others yawn

Yawning is often contagious, but there are some related factors such as age, empathic insight and degree of familiarity with the yawning person. When we see a person yawning, a kind of imitation is triggered.

But in fact it is not enough to see a person yawn but toeven fix an image that represents someone in the act of yawning or imagine that a person is yawning. In fact, just think of the yawn and take the gesture. Even if we are reading about someone who talk about the yawn maybe the act is triggered.

So the study is conducting research to show that there may be other factors behind yawning such as hereditary predisposition and genetic conditioning.

But what do you think of it? and above all have you ever observed yourself and have you ever noticed how many times a day you practice the act of yawning? There is a lot of attention about yawning when fatigued, as we have already stated.

But yawning is also associated with boredom, when we are doing an activity that we don’t care about that doesn’t capture it our attention, but which we consider boring then the yawn is triggered.

And when is there a feeling of hunger? A lot they yawn even when they are hungry and therefore in this way demonstrate their need for food. But in this article we wanted to focus on imitation.

So do you also happen to yawn when you see someone do it? If this happens, then rejoin that study that both humans and chimpanzees have this attitude of repeating the yawn once they see each other do it. Something very common that happens automatically.

Sleep, hunger, fatigue, imitation: here are the factors that cause us to yawn.
