Get To Know The Fact Behind Why Do We Yawn?

Yawning, is usually considered a sign of boredom or your body’s way of telling you to get some shut-eye. The tears that form in your eye when you yawn tell you that you are missing your bed.

The world famous saying “as contagious as a yawn” is so true. When you see someone yawning, you can’t really help yawning yourself.

What Happens When We Yawn?

If you observe carefully, you will realize that when you yawn, you are first inhaling air, which creates a slight pressure on your eardrums, and then you exhale.

What Causes A Yawn?

Like for any other action, there are numerous theories for why we yawn. As I said earlier, we inhale air when we yawn. And we feel the need to inhale excess air when the carbon dioxide in our blood increases. So our body tries to take in as much oxygen as it can.

Another theory is that yawning helps the brain to cool down. A study was carried out wherein ice packs were put on the subjects head and they were made to watch videos of people yawning. The subjects apparently yawned less.

A third theory states that yawns are caused by neurotransmitters (chemicals in the brain), like serotonin, dopamine, glutamic acid and nitric oxide. Whereas other neurotransmitters like endorphins decrease yawning.

The Cultural Aspect

Some people say that when we open our mouths to yawn, we are letting our soul escape and that we are letting the evil spirits enter our body. To prevent this, we are supposed to cover our mouths while yawning.

It is considered rude to yawn while we are attending an important lecture or a conference or a meeting. It was a tradition to turn your face and cover it with your handkerchief while you yawn. A loud yawn may even lead to penalties for contempt of court.


Contagiousness of yawning affects dogs as well. Domesticated dogs yawn when their owners yawn. Even the fact that fishes yawn has been documented.

In a herd, yawning is used to synchronize sleeping patterns. Contagious yawn is supposed to show empathy.
