#11. Why do we yawn?
One thing that is for sure is, that if you yawned while reading this article it is definitely not a sign of boredom. I mean there is no chance that someone could get bored from this great article!
Yawning as an involuntary action observed in many mammals. It has puzzled people for centuries. Perhaps the most intriguing observation is that is seems to be contagious.
You can make another person or even animal yawn by simply yawning yourself in front of them. Now isn’t that neat?
But why do we do it? One of the earliest attempts to provide an explanation stated that this is the body’s way to increase the oxygen levels in the blood when it needs to.
Modern day research however has concluded that a yawn actually lowers the oxygen levels. Another shot at this claimed that it is a way for the body to get rid of excess heat in the brain. Sadly enough, statistics show that the rate of occurrence is lower at warmer temperatures.
To this day we can do nothing to explain this mystery. Nothing but to yawn. And if you do yawn, just remember, that this is not due to this article being boring. That can not be proven just like all the other theories.
Good to read that, but i believe that the writer went a little bit hard on religion. Answers the writer talked about were not given by my religion. For example, the stars we think that we look at are not the stars but the light emitted by those stars and has just reached our sghit, is mentioned in my religion and was proved later by science. I am sure that real religions give the correct piece of information and real science have to prove them.
