Why is yawning contagious?

in science •  7 years ago 

I am 100% sure that you have ever thought about this issue. But what happened? Were you too lazy to search for information? Most likely, if you are reading this article, then you are either my subscriber (ahahahhaha) or you are interested in knowing more about this habit. Let's satisfy your desire.

Term

So, let's first find out what you mean by "yawn". Although no. Go to Wikipedia:

A yawn is a reflex consisting of the simultaneous inhalation of air and the stretching of the eardrums, followed by an exhalation of breath. 

Well, now you know exactly. We divide. Or not? Most likely, you would have formulated it differently: "Yawn is when we breathe deeply". OK, now that we understand what it is, let's see why looking at the kitty at the beginning you wanted to yawn.

Why is it so?

I bet that you were yawning today. And tomorrow, too, yawn. When do you yawn most often? When you are bored or want to sleep. All apart? No. If everything was so simple ... There are different opinions about what an additional function is for yawning. The most common version is the overheating of our brain. Imagine that he is like your old mac. It's worth running on it Crysis 3, as it starts to heat up. That's the same thing happens with your brain (Now it's clear about yawning with drowsiness, huh? Your brain is just tired).  So. And what about contagion? The most common version says that this is just a reflex and a relic of ancient times. Another version, less common - mirror neurons. What is it? This ... I won't say. This is a very big topic, which needs to be deepened. It is clearly intended for a separate article. Do you understand, yes? You should subscribe to not miss it. Have not you fallen asleep yet? And, hey, it's not because my article is boring, just the number of words "yawning" exceeds all admissible values and you yawned 3 times at least. So, that's all. Part of the mirror neurons wait for 2-3 days. In Facebook or Twitter there will be an announcement so you will not miss it. I'll leave the links below. Good luck.
