From humans to animals we all have one thing in common, we all yawn! Although, it's still a mystery why we yawn. What is a yawn and why do we do it? Narrated by: Dr. Moo.
yes, this is exactly where the problem is. she is way too busy and we can't be sure the next video has any narrative at all. By the way, where is Nate from the void? I mean, at this point, any voice will do

She used it correctly. A hypothesis is made before any data has been gathered. What Dr. Moo referenced is a theory because it’s based on existing evidence about what we know about how yawning affects the body. Laypeople don’t know that a theory and a hypothesis are two different things. Arrogant laypeople (like the guys lecturing a NASA scientist about terminology) don’t know that it’s even more complicated than “they are two different things.”

True or false? Let's test." What Dr. Moo cited IS indeed a theory. The only thing that is required for a theory to be a theory is that it is an explanation that is consistent with data that has already been gathered in past studies/experiments/etc. Theories that are "just theories" are theories that aren't yet strongly supported with evidence, but which still provide an explanation of the mechanisms. But that still makes them distinct from hypotheses, which are predictions of outcomes based on the mechanism supplied by the theory.
Having someone actually talking the lines instead of making us just read it with BLARING MUSIC going on is a huge improvement. Thank you. I look forward to more like this.
A fetus also yawns while still in the womb so that seems to undercut the idea that it has to to with oxygen levels or brain temperature. If it had to do with temperature one would also expect yawning to be more prevalent in warmer regions.
@@MorgothBauglir13579 There is no air inside the womb, (oxygen is supplied by the mother through the umbilical cord) therefore air-cooling the brain through yawning is not possible.
My theory: Its your body trying to move, stretch and be more active when you aren't being active enough to justify being awake. That's why you yawn at meetings, school or when you're watching a boring movie. Also when you are getting ready to go to bed but you have other things to do first. You typically stretch when you yawn. You stretch a lot of muscles not just in your face, but the rest of your body as well (arms, back and even legs and feet). It's your body trying to move and stretch and perhaps even breathe more when you are being stagnant but resisting the urge to sleep.
I was looking up this specific reason and happened to find you covering over the facts n stuff,immediately clicked because you make learning fun and entertaining
for sure not but 1) they need a known voice/character since Kyle's quick leave and 2) she can quickly record the audio for such an episode in her lunchbreak and the rest gets edited
Reminds me when an ex boss told me that customers didn't come for me they came for the food. When I left all my customers left too. And not they closed.
I'm glad Dr. Moo is here in voice, but if y'all gonna keep doing Because Science without Kyle, can we just get the Because Space portion with Moo? Because Science died when you let Kyle go.
@@MegaShepardsPie she isn't ANY kind of doctor mate, buying a diploma from an expensive University with essentially no campus and an 85% acceptance rate isn't exactly worth much..
I see you finally got a voice that's nice. Just a little note the background music is a little bit overpowering drowning out at times the person's voice.
Huh. Much better - I can see you noticed the tips mentioned in previous comments. This video was way easier to watch and significantly less boring. I mean you know people will constant nag about BS loosing the hair - but you've made a step in the right direction. Music varied, more artwork less reading words, and the lass narrating was clear and concise!
Fun fact: dogs also yawn when they are stressed or scared, specially during interaction with other dogs. It's very common to see a dog yawning when they are put together with a new dog they are not familiar with and are showing other fear behaviors. I believe that may also happens with humans. It does with me at least. I'm not rly good with social interactions, and I noticed that when Im nervour or unconfortable around someone I start yawning nonstopping. It's possible that this is just a way of my body trying to destress
"The reason why a yawn is contagious is because of empathy" makes no sense to me, because then shouldn't we mimick every other move someone does because of empathy? We do that only for yawns so there must be a reason that holds its own
Alexandre Géhin> We do that only for yawns so there must be a reason that holds its own Not really, we tend to laugh when we see someone laughing, we feel sad when we see someone cry, we tense up when we see someone looking scared, we get alert when we see someone angry.
I thought the leading hypothesis on the reason for yawning was temperature control, and based on that then the reason yawning is contagious is "if I'm near them and their brain is too hot then my brain must be too hot."
i've always heard it was our circadian rhythms, this way as a populace of nomadic peoples we would all be on the same timeline of sleep and wake. but then again, I'm a boomer so what do i know
It was poorly stated. Many animals are social, but humans are INCREDIBLY social. One of the reasons is biomechanical perception; when we see a person do something, the neurons we would use to do the same thing fire very faintly. They fire nowhere near enough to cause us to do the same thing, but we have a very direct and intuitive perception of other humans' states. This mirroring of neuronal states, as well as the vast number of neurons dedicated to facial expression and our preoccupation with sight, enable us to be intensely social. So much so that we respond very well to symmetry and not well to asymmetry. If you duplicate someone's stance, pose and mode of expression they will tend to enjoy your company more, and the opposite for the opposite. It could be that whatever autonomic system that yawning is wired to is on a hair trigger and just the smallest tickle of seeing someone else yawn (or imagining it) is enough to set it off.
hmmm they are listening, and avancing the style before it was the same repetitive part of the song, then it changed to the whole song on loop, and now there even narration
For me the important part is the narration. Don't get me wrong, I miss Kyle and respect Dr. Moo for stepping up to fill a role, but as a busy father with a full time job, I'm usually not watching the video, and more listening. Don't give up guys.
Shouldn't say "just a theory". Call it a hypothesis, instead. Saying it's just a theory confuses people into thinking other theories are just guesses instead of the immensely studied and peer reviewed subject matter that they are.
My theory is that when we sleep we take in more oxygen and when we wake up in the morning we yawn for a kick start to the day and we yawn at night or whenever we normally go to sleep because it's our body saying ok this is our normal time to fall asleep and the empathy thing might not even be a choice for people it is most likely for us to yawn when someone else yawns because it is a instinct of some sort or a involuntary response but that's just a theory a science theory but hey what do I know I am just a kid in high school trying to graduate
Who wrote this script? "It's just a theory"? Seriously? The writers need to know the difference between a scientific theory and a colloquial theory. "It's just a theory" should never come out of a science educator's mouth.
Though technically a theory is just a scientifically supported explanation for something, so there can be many theories that are not strongly supported, but not disproved, by evidence. So while in Physics and chemistry "just a theory" would be blasphemy, in psychology, biology, and other fields, a theory can be "Just a theory" as there are still other equal (not strongly supported) theories; thus, the phrase is less blasphemous in certain field like biology where application may be prioritized. And yes, I am a stir-crazy, bored person with no life and way too much free time.
@@IamI3rian You seem to be confused on the major difference between a hypothesis and a theory. A theory is tested while a hypothesis is yet to be tested. For examples of theories that are not strongly supported, might I suggest taking a psychology 101 course.
@@whiterabbit47 no no, you can't tell me what a theory is, and then tell me to go look at "theories" that aren't theories. A "theory that isn't tested" is by your own definition (and everyone else's) a hypothesis, and not a theory. If I didn't know better, I'd say you're really bored, and looking for some trouble, because no one alive would say... "this is red, but this blue thing here, it's also red. Except blue is never red., and red isn't real. It's all blue." That's you. Go get some sleep, or food... Talk to your girl, whatever you need. You're so done, you're leather. Take a minute, ok? Get yourself together. I won't ever tell anyone you said these crazy things. We both know you're better than that, just pick it up, mate. I'm here, if something is so awful for you that you may need an ear to lean on or a shoulder to cry into. 😁 Either way, you're broken, and not working correctly.
You don't get a large amount of gas exchange to replace O2. When you yawn you stretch the muscles in the throat which causes the one side of your sinuses to drain. Several times a day the brain turns this function on , were one side of your sinuses drains and the other fills up with mucus. This is done to regulate the temperature of the brain,by changing the insulating nature of the sinuses. To test this gently massage your sinuses if you hear a clicking sound you should feel mucus draining , at that point you should yawn .( clicking sound is made by air bubbles in your sinuses collapsing. The muscles stretched open the nasopharynx aperture to facilitate drainage. The reason you yawn when bored is that lactic acid is a stress and fatigue poison ,high levels of lactic acid cause the brain to over heat ,so the brain will try to cool things off using the above technique. If you don't believe me ask a sinus sufferer.
I think the way to find out why we yawn is in magic mushrooms. when I'm tripping on shrooms, every time I think it's wearing out, I yawn, and the high returns even more intense than before
I love how they only go over stuff most don't believe is why They completely skip how a lot of scientists think it could be a let over part of our body an instinct of sort like how you'll typically jump back from a snake because most believe you yawn from when humans needed a way to indicate it's time to best down for the night a wide spreading yawn as the sun gets low saying okay time to get ready to sleep

@@whiterabbit47 no no, you can't tell me what a theory is, and then tell me to go look at "theories" that aren't theories.
A "theory that isn't tested" is by your own definition (and everyone else's) a hypothesis, and not a theory.
If I didn't know better, I'd say you're really bored, and looking for some trouble, because no one alive would say...
"this is red, but this blue thing here, it's also red. Except blue is never red., and red isn't real. It's all blue."
That's you.
Go get some sleep, or food... Talk to your girl, whatever you need. You're so done, you're leather.
Take a minute, ok? Get yourself together. I won't ever tell anyone you said these crazy things.
We both know you're better than that, just pick it up, mate. I'm here, if something is so awful for you that you may need an ear to lean on or a shoulder to cry into. 😁
Either way, you're broken, and not working correctly.
You don't get a large amount of gas exchange to replace O2. When you yawn you stretch the muscles in the throat which causes the one side of your sinuses to drain. Several times a day the brain turns this function on , were one side of your sinuses drains and the other fills up with mucus. This is done to regulate the temperature of the brain,by changing the insulating nature of the sinuses. To test this gently massage your sinuses if you hear a clicking sound you should feel mucus draining , at that point you should yawn .( clicking sound is made by air bubbles in your sinuses collapsing. The muscles stretched open the nasopharynx aperture to facilitate drainage. The reason you yawn when bored is that lactic acid is a stress and fatigue poison ,high levels of lactic acid cause the brain to over heat ,so the brain will try to cool things off using the above technique. If you don't believe me ask a sinus sufferer.
This video made me yawn like 6 times man
Ok yawn... Now off to the Kyle Hill channel!
I think the way to find out why we yawn is in magic mushrooms. when I'm tripping on shrooms, every time I think it's wearing out, I yawn, and the high returns even more intense than before
Don’t get me wrong I love dr. Moo, but I’m really miss Kyle on this channel...
We yawn because its a stretch for jaw and throat muscles. Singers also do it and it helps with headaches and regulate ear pressure.
I love how they only go over stuff most don't believe is why
They completely skip how a lot of scientists think it could be a let over part of our body an instinct of sort like how you'll typically jump back from a snake because most believe you yawn from when humans needed a way to indicate it's time to best down for the night a wide spreading yawn as the sun gets low saying okay time to get ready to sleep
