YAWN!! Why we do it ?

A Cute baby Yawning

Even thinking about yawning can cause you to do it. It’s something everybody does, including animals, and you shouldn’t try to stifle it because when you yawn, it’s because your body needs it. It’s one of the most contagious, uncontrollable actions a body does.

There are many theories as to why people yawn.The most scientifically backed theory about why we yawn is brain temperature regulation. A 2014 study published in Physiology & Behavior looked at the yawning habits of 120 people and found that yawning occurred less during the winter. If the brain’s temperature gets too far outside of the norm, inhaling air can help cool it down.

You may also find yourself yawning more if you get migraines. During a migraine, your blood clots in your brain. Yawning helps to cool your brain down from that clotting.
