It is the end of the week and we are so tired due to lack of sleep hours that we see ourselves opening again and again our mouth during our friends dinner, in the cinema or even on the sofa while watching TV, but do you know why little scientist?
There are three theories to explain why we yawn, do you want to know them? Keep reading and find them out!
We are always trying to control every action of the human body, but, as yawns are involuntary actions, no one will ever be able to control them. According to specialists, that is a mechanism that the body uses to import oxygen so that our brain refresh and be able to be aware preventing us from falling asleep.
Conclusion: The best way to fight against sleep is yawning!
We all think so, don’t you little scientist?
There are 3 theories which are trying to explain it: Physic, Evolution and Boredom.
The mirror-neuron is a cell which is the main responsible for this mechanism, whose principal function is registering our behaviour on different situations during the day. Consequently, when we see someone yawning, the neurons register that behaviour and trigger out an auto-reflection, which is impossible to control, forcing us to repeat what we have just seen (in this case the yawn).
Do you think that if someone that you do not know yawned, you would also yawn?
Theoretically you would, but surely you will try to do everything in your hands to avoid it because you will not want to show empathy and affinity with that person. What about people who we have affinity with? It depends, but we normally yawn without be conscious we are doing it just seconds after that person.
So, what are your conclusion little scientist? Ours is that empathy and affinity matter!
Did you know any of these facts about yawns? Or do you know some more facts about it? Tell us what you know little scientist!
