READ IT WITHOUT YAWNING
We know that everyone yawns. But we are not sure exactly why? Yawning is one of the uncontrollable actions which happens with humans including animals, it’s uncontrollable, contagious and because of it, our body gives signs. The current researchers say yawning helps to know about the brain temperature, potentially for empathy. Maybe that’s why we yawn because our brain temperature is regulating. In one of the books published yawning of people occurred less during winter, If the brain’s temperature gets too far outside of the norm, inhaling air can help cool it down. Yawning happens when we are bored, tired or seeing someone who is yawning in front of us. People who have migraines some people yawn more because of the blood clots in the brain. So, yawning helps to cool the brain and reduce clotting. The good aspect of yawning will wake you up.
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.
Another reason you may yawn is because the body wants to wake itself up. The motion helps stretch the lungs and their tissues, and it allows the body to flex its muscles and joints. It may also force blood toward your face and brain to increase alertness.
It seems like there is no conclusion why we yawn because yet science has not conquered answer for it and we should just keep guessing until we find the answer.
