Try Not To Yawn While Watching This Video

Have you ever wondered why almost all the living beings on this Mud Planet(Earth) yawn a lot.? Do you think Yawning is Contagious? What exactly is Yawning?

Well there are a lot of definitions. Lets check what exactly yawning is according to Wikipedia.

According to Wikipedia, “A yawn is a reflex of simultaneous inhalation of air and stretching of the eardrums, followed by exhalation of breath. Pandiculation is the act of yawning and stretching simultaneously.Yawning in adults occurs most often immediately before and after sleep, during tedious activities and as a result of its contagiousness, and is commonly associated with tiredness, stress, overwork, lack of stimulation and boredom, though studies shows that it may be linked to the cooling of the brain.”

Science of Yawning

Well that definition seems to be lot more complex. Let me explain to you in a simple sentence, “Yawning is an act of brain to indicate an action. This action may be either tiredness or sleep etc..; ” I think that’s better and simple.

However, Science of Yawning is better explained in the Video inserted above. This video belongs to the YouTube channel AsapScience. I personally recommend you and everyone Β to subscribe to that channel if you haven’t already.

I bet you that you yawned atleast once while watching the video above. I myself yawned a lot of times… πŸ™‚
