In our home, you would have seen dogs, cats yawning. Even I had seen fish yawning inside my fish tank. also birds will yawn Penguin signal yawning that they are ready for mating. Snakes after eating big foods will yawn to align its jaws. A breed pigs which is called as guinea pigs to show its anger and to threaten the opponent will use the yawning. We the human beings when we are in the womb we started to yawn. This is what researchers say. Why we human beings are yawning? Are you saying we yawn because we don’t have enough oxygen Do you believe this? Sorry. A Challenge for all of you Let’s see who can watch this video completely without yawning Hi, I am your Mr.GK Hello Mr. GK Sir. I am your big fan I have cleared many doubts seeing your videos I have a doubt for a long time. The doubt is Why we Yawn? Why we yawn because we intake huge air and provide more oxygen to our brain so that brain will be active. This was believed for some time. Actually, if our brain doesn’t have enough oxygen or we don’t have enough oxygen when breathing then we will have breathing problems like wheezing or will fall due to dizziness. or some serious problems but we will not yawn. But, then really why we really yawn? Latest researches has given some explanations that yawning is happening due to this. The reasons are By yawning we intake huge amount of air inside us at that time air enters ours body not only through mouth. It enters through nose, ears and all possible ways The air which enters the body will control the heart beat. It regulates heart beat and blood circulation If Heart beat and Blood circulation flow is regulated and brain is getting blood only through this The heat in the brain is controlled by Yawning This is the first job of Yawning Actually we yawn because our brain is getting heated In order to slow down the heat process and to cool our heart and blood helps us by yawning. Our brain is also like a computer processing machine If you see CPU, laptop in the processor you will have cooling fan The fan will rotate automatically when the processor starts heating Same is our brain when we think or give more work to brain in some situation it will become and tired and if gets heated then the cooling process is yawning. You can test this directly. How? By keeping ice directly on your head so that it will cool can we stop yawning? Even such research was done They would say warm pack and cool pack They have tied these packs to the head and done the research. In that they have kept warm pack on some person head and cool pack on some persons head The persons who had warm pack on head has yawned 41% but the persons who had cooling pack on head has yawned 9% this is the output. Because of this only they have connecting it to brain and say yawning process is because of brain. This is what a research says. By this time, you would have started commenting the next question Why do I Yawn why I see someone yawning? Why I am Yawning when I see this video? These questions you would have started to type in comments This type of yawning is called as Contagious Yawn or Social Yawning We will get yawning when see others yawning. The reason for this is due to empathetic behavior i.e., from our childhood we learn things only by empathetic behavior Our learning will be high during the age of 4 and 5 we grasp things like yawning by seeing others and we will do it automatically. There is another reason for this. This can be said as Non- conscious mimicry or Chameleon effect. You all know what is Chameleon. This is nothing but we do whatever the person in front of us unknowingly. For example Ladies will do mostly If they see someone sitting with Crossing one leg over the other they will also do. They will not do this intentionally. They do unknowingly. We also do comb our hairs when someone does Gents also do this type of simple things. also things like coughing, clearing throat These are done unconsciously imitated by seeing others. So, yawn is also one of these things. We have lots of neurons in brain out of which mirror neurons are one of the type. It will fire when it see things like this They will say this as copion like we yawn when we see it This is done by mirror neurons. The main job of this is self-defense like learning things, self protection, awareness and being conscious. Like if 10 peoples run suddenly we also run. So things like this helps us to be more conscious and be more self-defensive. These type of neurons helps us for these things. social or relative wise or a group of peoples like they say social animals this is because we are able to adjust and align with others in any situation. So, these type of neurons helps us by copying others behavior one of such thing is copion The mirror neurons will not activate only when it see someone yawning but also when it hears the sound. It will also makes us to copy it and we do it. Hereafter, if someone says that your lazy when yawning tell them i am not lazy since my brain has worked hard it has been heated I yawn to make it cool and become more energetic. I am just cooling myself. and you can say confidently that I am active Finally for you Laughing. Tell me now how many of you seen this viewed this video without yawning mention the details in comments also mention the place where exactly you yawned. There are lot of things need to learnt about our body and brain I have mentioned Brain & Physiology playlist in the below links visit that link. They have lots of information about our sleep, Teja Vu, Jamais Vu brain, vision and lot other has been discussed. So, visit the links and we will also speak more here in the future. There are lot of things which we need to learn along with the kids So stay connected with Mr.GK. Thank You.
