Have you ever that yawning has yet to be scientifically explained? WELL NOT ANYMORE!!! Today, scientists cracked the code of the mythical yawn. As you all may very well know (I’m talking to those late night studying students or workaholics) yawning is associated with sleep or boredom. However, you may not know that yawning may also be done in the anticipation of important things or stress. And I’m just here to say that some people think that yawning takes in more oxygen, however that is quite untrue.
OKAY. The new part is that scientists have performed research which points towards the belief that yawning is to “cool” the brain. Basically, taking that huge gulp of air helps to regulate the temperature in your brain. Scientists also discovered a pattern which supports this hypothesis. They did their research in Arizona and Vienna, where scientists recorded the amount of people yawning in the summer and winter. It turns out that yawning occurred much more frequently in temperatures around 20 degrees Celsius. This then shows that people tend to yawn in certain temperatures. I never really noticed it myself, but I do tend to yawn a lot more in than winter than when I’m kicking my sheets around on a hot summer night.
