admit it, last time you yawned, you tried to get as many people to join in as possible 😏 go on … we all do it … if you don’t, then you should! it’s funny 😂
that pretty much sets the tone for today! we’re going all out yawn central up in this beast 😎
#tdil the reasons why scientists think we yawn and why yawns are contagious 😲 <- that’s as close as we’re getting to a yawn emoji 😂.
now, disclaimer alert! unfortunately, i can’t give you the 100% reason for both of the above things because yawn experts (yes, they exist! 🙈) don’t actually know for certain 😕 basically, they’re experts at something that they don’t actually have info about 🙃 #awks.
anyway! i’m going to stop attacking yawn experts and tell you some cool info 😬 for years now, it has been thought that yawns were a way of getting us to inhale extra oxygen so that we feel enriched and awake … turns out that this thinking is actually a myth! 😱
steven platek, a psychology professor from georgia gwinnett college, says that it is much more likely that yawns are a way of cooling your noggin down 🤔. you see, as the organ that uses up 40% of your metabolic energy, your brain tends to heat up more than your other organs 🌡.
platek’s theory states that the action of when we open up wide and take a gulp of nice fresh air, it travels through our upper nasal and oral cavities. these areas are heavily populated with tons of blood vessels that go fairly directly to the forebrain … therefore, the blood is cooled when it goes into the brain #madcooling 😏.
it’s not all just a theory either, when studies were carried out on mice, an increase in brain temperature was found to come before a yawn … after a yawn, the rodent’s brain temperature decreased 👍🏻 (hopefully no mice were hurt in this study 😕 … surely it was just observation!?).
anyway, that seems fairly conclusive, doesn’t it?! platek is pretty certain that he’s right with his whole brain cooling theory … i’m pretty much with him to be honest 🤓 (but really, who am i to talk?! 😂).
* random extra yawn fact: snakes and fish both yawn!? 🐍🐠 *
right, next on the agenda! why on earth are yawns contagious?! like, how can even reading the word yawn make some people yawn for reals?!
honest answer? it’s another one that scientists can’t answer 😒. that said, they have started to rule out the theory that we contagious yawn through empathy 🤔.
a study at duke university recently found that there was actually no link between empathy and contagious yawning 😕 they tested lots and lots of people – of all ages – and concluded that it’s not empathy … but they have no other conclusion 😳 #helpful.
how unfulfilling!? 🙈 don’t you hate it when you think you’re about to learn something and then it ends up being nothing? 🙃 #sozzaaboutthat. that said, duke university are continuing their tests and hope to find a real life reason … so i’ll keep you informed 👍🏻
in the meantime, why don’t you see how susceptible you are to contagious yawning by using this scientific test! stick in the comments how long you last 😏
right, on that rather dull note, i’m going to leave this here 😂 at least the yawning stuff at the start was interesting?
gooooooodbye! 😅 #tdil
got to love a fact that is entirely based on theories 🙃 feel like learning something a bit more concrete? like how to take a picture of a black hole? just go ->here<-
(just look at that super cute lil red panda yawning 🙊 omgeeeee 😍 … anyway, i think i’m allowed to use that image … license is ->here<-)
