The Science of Happiness!

[♪ INTRO] Ahhh! Where I live, it’s that magical time of
year again: Snow is falling! It’s cold outside. Roads are icy. It’s dark by like mid-afternoon. I guess now that I think about it, not my fave. But that doesn’t mean there aren’t other
reasons to be happy this time of year. Science makes me happy. Snuggling in and watching videos makes me
feel all cozy. So, let’s explore the science of happiness. Let’s start with love and chemistry. Here’s Michael explaining why Valentine’s
Day should be less about hearts and more about your brain. It’s February, which means, at least here
in the the U.S, your eyeballs are getting accosted by a barrage of red and pink heart-shaped
lovey-dovey stuff. Now, I don’t want to rain on anyone’s
Valentine’s Day, but this is bogus for a few reasons. One, our hearts look nothing like those symbols,
and two, our hearts have very little to do with how we actually feel love. So if you want to make a more accurate valentine,
I suggest you cut that construction paper into the shape of a brain, or more specifically,
the limbic system, or even more specifically, the hypothalamus. See, the limbic system is the emotional center
of your brain. It guides your emotional, motivational, and
reward processes, and basically makes you feel all the feels, from pleasure to fear
to anger. It also influences some of your biological
rhythms, like sex drive. Nerve receptors all over your body send sensory
stimuli, say, the sound of a loved one’s voice, or the feeling of a hug, to the limbic
system, where it eventually gets forwarded to the hypothalamus . Perched on top of your brain stem, this small
but mighty bit of brain is your body’s visceral ground control, overseeing your entire autonomic
nervous system, meaning it’s in charge of processes you don’t consciously control,
like blood pressure, digestion, and heart rate. It’s basically the boss of all the bosses:
the CEO of your body. When it comes to love and other feels, the
hypothalamus uses those autonomic pathways to cause physical responses to match your
emotions, like how the sight of a secret love can leave you sweat-soaked, with a heart that
feels like it’s going to jump out of your chest. In the same way, someone who’s heartbroken
may experience their emotional stress in a very visceral way, for example, through heartburn,
high blood pressure, or changes in sleep and appetite. Guided by your hypothalamus, your autonomic
nervous system also influences the skeletal muscle system that lets you pull off facial
expressions and posturing. So when it comes to communicating emotions,
from “back off” to “come hither,” that’s your hypothalamus talking. And, it influences your endocrine system,
which uses hormones to make your body do and feel all sorts of things, including, probably,
love. For one thing, it controls your pituitary,
the master gland that then manages most of the other endocrine glands in your body, as
well as the hormones they release. That covers everything from your stress and
excitement response to your libido. But the hypothalamus also makes a few special
hormones of its own, like oxytocin, the famous “cuddle hormone,” which is involved in
social bonding, among other things. So in the end, if you want to get real about
love, toss out the heart and start saying “I Hypothalamus You.” I just hypothalamus that guy. I should tell him that. Better yet, I should show him! If only I had a tail and could wag it to show
him he makes me happy. Maybe I’ll just tell him. But tail wagging, while it can be a sign of
happiness, is much more subtle and communicative than I originally thought. Here’s Olivia unpacking some of the research
into why dogs wag their tails. As cute as it would be, dogs can’t talk,
and their faces aren’t as expressive as ours, so it’s sometimes hard to tell what
they’re thinking. But dogs do communicate in one way we can’t:
with their tails. Those fluffy tails are constantly conveying
your dog’s mood, but just because she’s wagging it all over the place doesn’t always
mean your dog is excited to see you. A tail wag doesn’t always signal happiness
and friendliness. It’s way more complicated than that. The exact behavior can vary depending on the
breed of dog, but the general pattern is the same. If your dog lowers their tail between their
legs, it probably means they’re scared, anxious, or submissive. If they hold it up, something has captured
their interest, like a squirrel! The higher the tail, the more aggressive the
dog is feeling, although the relative height varies between breeds. Some dogs just naturally hold their tails
higher than others. If their tail wags slowly, your dog is maybe
a little uncertain about the situation. But if it’s waving energetically from side
to side, it’s probably exactly what you think: a happy, enthusiastic hello. As strange as it sounds, a pair of studies
by a group of Italian researchers showed that which direction a dog wags its tail is important,
too. In the first experiment, 30 dogs were exposed
to four different stimuli: their owners, strange humans, a dominant unfamiliar dog, and a cat. The dogs wagged their tails much more on the
ride side of their bodies when they saw their owner, and slightly more on the right when
they saw a strange human. They also tended to wag on the right when
they saw a cat, but the movements were smaller and more insecure. But when they saw a dominant, strange dog,
they wagged more on the left side of their bodies. According to the scientists, this means they
wagged on the right when they saw things they’d like to approach, and on the left when they
saw things they’d want to avoid. See, the two sides of dogs’ brains have
different specialties. The researchers suggested that one side handles
approach responses, like when a dog greets its owner, and the other side handles withdraw
responses. And which way the tail waved seemed to depend
on which half of the brain was being activated. A follow-up study with about 40 dogs showed
that other dogs could actually pick up on this. When they saw a video of another dog wagging
its tail on the left, they got anxious, and their heart rates went up. But when they watched a video of a dog wagging
its tail on the right, they stayed relaxed. It’s possible that this is a way dogs communicate
with each other, since many of them have easily-visible tails. So if you want to become an expert dog whisperer,
keep a close eye on that tail. It could be telling you more than you’ve
ever realized! What a cool job: to be a researcher who studies
what dogs’ tails are telling us. Another fun job would be a gelotologist, someone
who studies laughing. Just like tail wags, our laughter can be a
lot more complicated than just thinking something is funny. In this video, Hank explains the physiology,
psychology, and sociology of why we laugh. Hey, you know what’s funny? Why people laugh. Laughter is a physiological response that
involves at least fifteen facial muscles, the respiratory system, the brain’s limbic
system, and, if the joke is really good, even your tear ducts. But laughter doesn’t always indicate happy
times. It can actually be a sign that something is
seriously wrong with your brain. Gelastic seizures, or uncontrollable and random
laughter or crying, can indicate the presence of brain tumors, or other conditions like
pseudobulbar affect, a neurological syndrome that can affect stroke and brain-trauma survivors
and M.S. patients. These conditions are sometimes called emotional
incontinence because the sufferer can’t control these outbursts, which often have
no root in how they’re actually feeling. And how we feel, especially in groups, seems
to be what laughing is all about. Some laugh researchers, and yes they are things,
known as gelotologists, think much of our laughter is rooted in strengthening social
bonds. We’re much more likely to laugh in a group
than we are alone, and we tend to laugh more easily around friends and family. That shared experience brings us closer, makes
us feel part of a group. We also laugh to express relief, or to ease
our nerves in stressful moments. Researchers theorize that there are a few
specific reasons for laughing. First there’s the incongruity theory, which
maintains that it’s the element of surprise that triggers laughter, whether it’s an
unexpected punch line or your friend tripping on a throw rug. Say you’ve been watching people walk through
a room all day. Your brain registers this as predictable and
boring behavior. Then your friend walks in, trips on a rug,
and drops a big box of ping pong balls. Once you’re sure your friend hasn’t, say,
fallen on a bag of rusty knives, you find the fall hilarious because it was sudden and
unexpected, and incongruous to the string of people you’d seen safely walking by. And because: ping pong balls. Babies and little kids go for this kind of
laughter a lot. They think really simple, unexpected things
are funny, like playing peak-a-boo for five consecutive hours or pretending a banana is
a telephone. Now, if you are the one who just tripped on
the throw rug, you’re much more likely to laugh in surprise if you see your friend laughing
with you. This goes back to that shared laughter as
social bonding thing. You’re probably feeling pretty embarrassed
and tense, but are also relieved you aren’t hurt. That is where the relief theory comes in. Because laughing is like a mental mini-break. Your brain is constantly working, taking in
all sorts of information and ordering the body around. Sometimes it just needs a happy surprise. This is particularly handy in stressful moments. The whole Hollywood wisecrack in the middle
of suspenseful scene phenomenon is predicated on this idea. When Han Solo is in mortal danger, he cracks
a joke to lighten the mood. He needs it, Chewie needs it, the audience
at the edge of their seats need it. Humor helps us cope with stressful situations. It sort of recharges our brains to face the
task at hand. Scientists call this releasing cognitive energy. The rest of us call it comic relief. But, back to you tripping on that throw rug…
if everyone in the room is laughing at you, and none of them are your friends, they may
be proving the superiority theory of laughter. It means they’re laughing at your misfortune,
and it probably means they’re a bunch of jerkfaces. Superiority laughter still promotes bonding,
in an us versus them kind of way, but it doesn’t show much good will. Teens make fun of their parents and lots of
other people. (Okay….so do lots of adults… ) But our teen years are usually awkward and
confusing, and superiority laughter may help ease some of that pain. So simply put, we laugh hardest at what we
know best, and at what stresses us out the most. And maybe that’s why it’s great for you,
both physically and emotionally. It reduces the release of stress hormones
that jack those fight-or-flight feelings. It lowers your blood pressure and oxygenates
your blood flow. It even increases your T-cell levels that
help with immune response, and B-cells that produce antibodies. Plus, laughing 100 times is estimated to burn
as many calories as a 15-minute bike ride. So you see, laughter is not the best medicine, but it’s not a bad medicine, either. Okay, now here’s something that… doesn’t
make me laugh, but it does make me feel happy and relaxed and…tingly? ASMR, or Autonomous Sensory Meridian Response,
is one of those phenomena that’s probably been around a long time, but it wasn’t until
the existence of the internet that people started being able to compare notes about
it and therefore study it. In this next episode, Hank explains the still-pretty-new
research into ASMR. And don’t worry, if ASMR is not your thing,
Hank only whispers for about 5 or 6 seconds right at the beginning. And right at the end, but I’ll cut him off,
I promise! I’m gonna get real up close and personal
for a sec, but bear with me. It’s for science. Oh, I see you’ve come in for a haircut. Let me just get my scissors. Did you feel anything strange just now? Maybe some shivers down your spine, or a pleasant
tingling sensation? ‘cause, if so, you’re probably one of
those people who experience what’s known as ASMR, or Autonomous Sensory Meridian Response. And according to research published in the
online journal PeerJ, it’s a real thing! ASMR is, basically, the tingling sensation
some people get in response to a stimulus. Over the last few years, it’s gotten more
and more popular, with communities of hundreds of thousands of people forming around YouTube
content designed to trigger that shivery feeling. Often, the videos will involve some kind of
consistent sound or visual, like whispering, softly crinkling paper, or repeated movements. Lots of them also incorporate personal attention
and roleplay, a content creator giving a haircut to the person behind the camera, for example. But there are also plenty of people who don’t
believe it’s real. The weird thing is that because ASMR is so
new, scientists don’t know much about it. But if hundreds of thousands of people say
that they’re experiencing something, a biological thing that we didn’t even realize was a
widespread phenomenon. Well, researchers are going to start investigating. After all, that’s what researchers do. The first peer-reviewed study of ASMR was
published in March by two psychologists from Swansea University in the UK. They wanted to do four things: define the
ASMR sensation, figure out what causes it, explore the connection to similar unusual
feelings, and find out if it really does help with depression and chronic pain. So the researchers surveyed 475 people online,
all of whom said they were sensitive to ASMR, and asked them questions about YouTube videos,
specifically. Most of the subjects described the feeling
as a spreading tingling sensation, and 63 percent observed that it started in a particular
place in their bodies, like their scalps or shoulders. As for what induces ASMR, whispering was the
most popular trigger, with three quarters of the participants choosing that option. The second-highest percentage was 69 percent of people, who said that personal attention triggered their ASMR. Other common causes included crisp sounds
and slow or repetitive movements, though about half the participants needed a specific type
of environment for the ASMR videos to work at all. And while 98 percent of survey-takers used
ASMR videos to help them relax, only 5 percent said they found them sexually stimulating. The researchers also wanted to see if people
who feel ASMR are more likely to experience synesthesia, where senses and body parts get
mixed up. A synesthete might describe it as hearing
colors or smelling music, for example. 5.9 percent of the participants did seem to
have some degree of synesthesia, which the team confirmed in follow-up interviews. But that wasn’t a significantly higher percentage
than in the general population, where about 4.4 percent of people have it. To learn more about ASMR’s effects on mood,
depression, and pain, they analyzed subjects’ depression risk of their subject with popular tests for depression and anxiety. Then they asked the survey-takers whether
they found that ASMR affected their mood, and eighty percent said yes. Oddly enough, half of people said that it
didn’t even matter whether they felt the tingling at the time, just watching the videos
made them feel better. Participants then rated their mood on a scale
of 0, worst thing that ever happened to you, to 100, happiest moment of your life, before,
during, and at intervals up to three hours after an ASMR session, and a clear trend emerged. People’s moods were kind of meh before the
session, much better during and immediately afterward, and then slid back down over the
next few hours. But among people who had high risk for depression,
the average mood improvement was more than double the change for those who had low risk. And around half of the 91 people with chronic
pain said that either ASMR did help with their pain, or that they weren’t sure. Among those people, the survey showed that
the tingling really did ease their symptoms for at least those first three hours. The researchers point out that there’s still a lot more
to learn about ASMR, like its physiological effects. Some scientists have even suggested that the
tingling feeling might be some kind of tiny seizure. They’re also curious about ASMR’s possible
connection to synesthesia, as well as misophonia, which is basically the opposite of ASMR; when
certain sounds, like heavy breathing or chewing loudly, make you want to punch a wall. Okay, I promised I wouldn’t leave you with Hank whispering, so I have one more video to leave you with. This one is actually not about happiness,
but it’s a fun example of one of the aspects of SciShow that makes me the happiest: you! I feel lucky that we have such an engaged
audience that asks questions and demands answers. I think that’s good for SciShow, but also
good for the world. It pushes us all to learn and try new things. I’m being serious, and you’re going to
think that I’m not once I tell you what this next video is about, but I am! So please keep that in mind, as Hank explains
what research we could find to answer the question, “Why do we have butt hair?” I hope it brings you joy. SciShow recently began producing its fifth
year of content. Something that we are extremely proud of. And we’re also proud of the community that’s
grown around these videos. We’ve covered a lot of topics, both trivial
and profound, and we worked very hard to capture both our
fascination and excitement as well as our deep desire to always get things
right. And over the last year, you may have noticed a comment on, we think, every – single –
SciShow video, asking us one question. We have ignored this question long enough, it is time we took it on. litojonny wants to know, why does he have
hair around his anus? Well jonny, the reason we haven’t answered
you is because, you know, like despite the fact
that everyone gets their own personal pocket sized
supercomputer, and that we can send robots to Mars, and convert the entire face of a planet to
human use, we still do not really know WHY humans have
butt hair. And it may not surprise you to learn, that not a whole lot of research has been
done on the “Why” part of this question about butt
hair. But a fair amount of study has gone into the
medical problems that butt hair can cause. For example: Pilonidal Disease is a chronic
skin infection caused by hairs that get embedded near the
top of the butt crack, which, if you want to impress your doctor, you can describe by its technical name:
the intergluteal cleft. So as the owner of the butt yourself, you probably know that butt hair does seem
to have more downsides than upsides. So given that, what, if any, purpose does
it serve? Well there are a few theories out there and maybe some enterprising scientist out
there, watching right now, can do some research on them. But here’s what has been proposed. Theory number 1: Butt hair exists, because there’s just no significant
evolutionary pressure against butt hair. Sure, it’s sometimes inconvenient, and, depending
on the moment in cultural history, it might be considered unsightly, but it appears, that butt hair has never been
a significant reason for one human not to make babies with another
human. It’s important to keep in mind, that not every
bit of our physiology needs an evolutionary purpose, so butt hair might just be another side effect
of unintelligent design. Theory number 2: Scent communication Body odor definitely has a negative connotation
in today’s world, but there’s little doubt that communication
through scent has played an important role in the evolution
of humans. After all, that likely why we have body hair
in the same areas where we produce body odors. The hair is there to hold onto sebaceous,
or oily, secretions, that have their own smell, and are also consumed by bacteria, that create
even more smells. Since we all produce different smell compounds,
and all have our own microbiomes, each individual human actually smells different. And if our early human ancestors were anything
like other animals, and they probably were, their personal smell probably helped with
everything from broadcasting territorial rights to attracting mates. Butt hair then may be just another way our
oldest human ancestors enhanced their smell profiles. Theory number three: Friction. In addition to giving off smells, humans have
also always done a great deal of walking and running. And skin rubbing on skin (especially in areas
where that skin may be moist and dirty), can cause irritation, rashes, and even serious,
debilitating infection. It’s even possible, that those sebaceous or
waxy secretions, that help produce body odor, are held in place by body hairs to provide
an added benefit, acting like a natural anti-chafing cream. Now this theory, of the ones that we have
talked about, is most appealing to me, personally, but it’s very difficult to test, because shaving,
or otherwise removing butt hair, and then having someone run 20 miles on a
treadmill, is not a good experimental design. Because, there’s no way to know, whether any
irritation is caused by the lack of hair, or whatever technique was used to remove the
hair. None of which sound fun to me. But I have come up with an alternative experimental
design that I like quite a lot. Just interviewing a few hundred runners about
how much they need to worry about butt chafing, and then measure the density of their anal
pelage, to see if there’s any correlation between whether they chafe and how hirsute
their buts are. Which is not an experiment that I want to
to do personally. But if there’s an expert out there, in anatomy
and physiology, who is up for tackling this prickly problem, please, take it on. And if you get any useful data, definitely
let us, and litojonny, know, how it went. Thanks for watching and being curious about
the world. I speak for the whole SciShow team when I
say it’s our honor to make videos we think you’ll enjoy. If you have questions or topics you want us
to research, let us know in the comments of any video. We read them, and we love hearing your ideas. Thanks for watching. I hypothalamus you. [♪ OUTRO]

  1. So this is now what you are doing – re-using past sessions and incorporating them making "new" content. No SciShow. That is not new content it is the same as re-runs on television. Unsubscribed.

  2. I just popped in to say that the science of happiness is like the science of flatearthers, it doesnt exist and stop kidding yourselves

  3. Why our urge to poop or pee get more intense once we are nearing the toilet even though sometimes the toilet is occupied or unavailable and we know it?

  4. Laughter can be seen as a type of communications reflex. We often laugh at things that would or could be perceived as painful. A laugh communicates that it is not serious. On both sides, the person who hurts themselves might laugh to say it isn't serious or the person watching might laugh to say it isn't serious.
    If you play peekaboo with a child that child might get scared but they might also laugh because they realize instinctively that it is not serious. You can watch videos of this.
    This would have been useful when bumps in the night startled our ancestors as they tried to sleep. If a fart wakes you from a deep sleep a laugh tells your startled wife that she doesn't need to panic. Which brings us to why we don't find things funny. If something is painful like a football in the groin many will find this funny because they have had the experience and know that it is not serious but the person getting the football in the groin is probably in pain and that pain prevents the laughter, it just too soon. If they rewatch that video on YouTube they are given the chance to reassess just how serious it actually was and perhaps the over the top reaction might be seen as funny.
    Think of a comic who pushes the edge and points at some social issue that is currently or recently heated. Let's take the trans issue because that was recently brought up by a comic who was approached after a show by an angry audience member who is trans. They express how hurtful the joke was how it offended them and how they wanted the comic to stop telling it. A joke will never "land" with everyone, some don't get the joke which often happens when you can't relate to the pain or suffering that is presented or how it was trivialized to be perceived as not serious. For some it will be too soon and the pain current or unresolved and being told that is not serious can actually be more painful. We can laugh with others or we can laugh at them, the message is the same.

  5. Where i live it's that terrible, terrible time of the year again.
    The sun is HOT AND SHINY, the air is very humid and it's cooking me to death
    I want to die

  6. hello can you look at my idea about gravity and radiation

  7. The heart shape is not based on that of a human, but rather a chicken. These birds have been on the table for quite a long time and the three chambered organs would actually be gifted to that special someone thanks to their symbolism and availability.

    Times have changed. Many people don't kill their own food anymore and it may be a little unsettling to find one in your love letter.

  8. Ok the BUILDUP to the last video was a very good demonstration of how comic relief and incongruity work, butt I have absolutely no idea what other purpose it served in this anthology

  9. I know I watch a lot of your videos, but, I don't think we are to the hypothalamus level just yet. So until then we can just call it like.

  10. An older man behind me in line at the store brought up a question that I'd never thought about: do we actually need dry gas in Winter to keep our fuel from freezing/slushing on cold nights? A lot of gasoline sold in the US already has alcohol in it. Is that enough, or do we still need to supplement?

  11. If tommorow dogs would start talking, could we really justify to dominate, breed, and sell them like that any longer? And why is it ok just because they don't speak human language, or think human thoughts? As far as we know, they have the same basic emotions like humans do. I don't think it would be so cute.

  12. The hearts are actually meant to look similar to butts and cleavage in shape, the real reason for valentine's day

  13. I go cycling a lot and when I shave my butt hair nothing is wrong until I do a 40 km+ ride, the area between my legs gets red and painful.

  14. I've always wanted to know why bright lights make me sneeze, I've had it since I was a little kid and it's always fascinated me; photonic sneezing, I believe its called

  15. All animals share a very similar brain that responds the same way to the same chemicals and neuro signals, in fact any animal can be treated with the same anxiety medication humans use because humans are animals too (we are part of the great ape family). All animals (including ourselves) have thoughts and feeling and in fact have the same emotions.

    Anyone who has had a pet can do a simple demonstration. When your cat or dog come up to to be pet they are doing two things: 1. They are coming to you not your sofa, not the table, not anything else, they go to you. They have remembered that you pet them and when they want to be pet again they know to come to you. They are to distinguish between you and everything else. This demonstrates thought. 2. When your pet gets the pet they wanted they perform a response or pleasure, and when they get pet the wrong way they perform a response of discomfort. This demonstrates that they can feel. Using MRI scans we can see the areas of the brain light up where emotions are in the same areas of our brain when you account for size. The fact we can treat other animals that appear to show signs of mental illness using the same medication that we use to treat that mental illness shows they not just feel but also have emotions and the same ones.

    Why can't we "listen" to what animals have to say when they communicate? Well, you can and you can't. All things communicate uses their senses, it what senses they use to communicate that can differ. When it comes to mammals the majority communicate using primarily visually and secondarily tactilely and tertiarily verbally. It is not to say that don't use their other senses to gather information, just they don't use those sense to express information. Perhaps you are thinking you have seen your dog sniff to gather information before. What they are doing if sniffing for pheromones, which humans do the same thing after shaking hands but this isn't the same thing as expressing information. It is not common to see a communication model not like the one mentioned previously in mammals but some mammals do, such as humans. Humans flip what most mammals do and communicate primarily verbally and secondarily visually and tactilely.

    Your communication model is something  are born with and language is something you learn. Language is based on communication models, so all human languages you learn with primarily involve verbal components. Usually we don't involve visual communication in our language but rather use the same visual communication across our species and call this body language (which is a poor term as it isn't a language). There are some visual languages (such a sign language) but all of those languages are based upon the use of verbal language and directly translating that into hand singles or otherwise to express thought in the same way you do verbal language. Because some visual languages exist, we can and have taught other animals how to "speak" our visual languages, such as Koko the gorilla. We have a hard time learning other species visual languages because unlike ours they don't base their visual languages in a verbal like way.

    Can other species that share the same communication models communicate with one another. Yes, but not completely. While latin isn't a communication model but rather a language we can latin demonstrate a point. There are languages called romance languages with are based upon latin: spanish, french, portuguese, italian, romanian, etc. While all of the romance languages are different languages, because they are based on the same language they can use those different languages to express thought amongst themselves without having to know the other language but have difficulty expressing increasing complex ideas. Different species that share the same communication model have developed their own languages based on the same model and can express ideas amongst each other but the more complex the idea the harder it is to express it. Just like we can express ideas in english to someone who only understands japanese by using on simple level, but when we share the same language we express even more complex ideas.

    Why this is important when it come to autistic people is understanding our communication differences. Through my own understanding and experiences with communication as well as speaking to other autistic people it is my understanding that perhaps our communication model is much like other mammals being primarily visual and secondary tactilely and tertiarily verbally. Having a different communication model could explain our communication differences and sharing the same communication model as most mammals could explain we understand other mammals a lot more easily.

    When thinking about how I express emotions, my emotes are not naturally my face (a demonstration of primarily using verbal communication up close as having facial emotes aids in verbal communication in a close range to demonstrate subtlety of language) but rather my stims using the rest body. Emoting with your body is something allistic people do to a degree but not much as their face, much like my primary emotes being with my body but there a few natural emotes with my face such as smiling when in uncomfortable situations (which other primates also use to demonstrate aggression and ward off others) but there a few stims I also do using my face but not as many. Something that also comes naturally to me is expressing how I feel more complex ideas tactilely, such as directions, needs, wants, providing comfort, expressing emotion, location, etc.

  16. I think ASMR gives you the audio experience of an intimate situation with another human being, something we social animals are wired to crave. It also seems similar to someone gently caressing your skin which can also give a shiver response. It is just vibration we are feeling after all!

    I wouldn't be surprised if the hypothalamus is producing bursts of oxytocin when this is happening. Can we get some brain scans and check hormone levels in these tests?

  17. Mine failed one of its basic jobs today. I worked a whole day so utterly focused, I neither ate nor drank and never got an indicator of hunger or thirst until I stood up…and fell over again.

    Also, I feel like the odd person out because I HATE that ASMR feeling, makes me want to throw up!

  18. I'm a Biomedical research scientist who have studied more than a dozen human diseases and read broad spectrum of articles on daily basis. I've really loved this channel's way of conveying cutting edge science to the public. Let me volunteer my time off work and work for your channel as a writer or something. I'm excited to do my part in public education. Trust me!

  19. I don't know about ASMR, but watching Hank talk sexually stimulates me…

    (not really…bcz I'm a guy…
    but just that he's so good)

  20. What if I’ve grown numb, I don’t feel anything anymore? Not a single persons hug makes me feel anything. Nothing at all works

  21. I think I’m too happy because sometimes people find me annoying or come across as fake…
    but I can’t help it! I really love my life and my family. I can see how that can irk some folks.

  22. Verry good I liked it. Also the dog part was informative and the butthair part answered what I was thinking about once in my life. Verry deep knowledge. thx 🙂

  23. Why do not doctors take food consumption and nutrition in when prescribing medication?
    Like what do you eat and can you make document your food consumption for a mouth?

  24. I just got another dog (Australian Shepherd), and the previous owner cropped its tail. All she has left, is a two inch nub. That’s why I like dogs more than people.

  25. I get frustrated when I think I'm clicking a new video, and it's a collection. Could there be something in the video name, to show?

  26. omg ive only ever been able to describe this as "ghost tickling" because i LITERALLY feel someone tickling me even if their fingers are an inch away @ 10:23

  28. I want to know when humans decided it was a big deal to have a thing called New Years Day. I assume old cultures had a similar even, though usually in spring to celebrate the end of winter (Would this be so in both north and southern hemispheres – I only know a bit about some older cultures from the northern half of this fine planet). Why is New Years such a big deal anyway??

  29. Why do asmr make me want to punch wall? Why does unemployment make you depressed, even if you are an introvert who loves being alone. And what is the science of introverts? And another thing; I was born as a left handed person but my parents trained me to be right handed before I can remember. Why did they do that? I asked but they don't remember why, and last year I heard about a Swedish study where they did this and saw some effects from that. I was born in the late 80's, hope you can look into this 🙂 Love watching this show!

  30. So, anyone else started thinking about Ash from Evil Dead 2 during that part about laughter being a sign that something's seriously wrong?

  31. How does the brain compensate a loss of a sense with the other ones? (Aka lose eyesight = better hearing?)

    Your other senses dont change so how do they get more attuned?

    Since we're talking about brains
    What is dissociation? Whats it good for? Why does it happen? Is there a way to snap out of it? Is it the same thing as the feeling of overwhelm? Why does it reoccur? Why is it an unpleasant feeling if its purely detachment? Its not apathy exactly.

  32. Great show guys.. Took me way to long to find out about you but love the effort and knowledge and awakening curosity you bring through these vids.

  33. All of our emotions/consciousness are just chemicals and electrical reactions taking place inside of your body nothing matters

  34. The ASMR section was interesting, as I am indeed a Misophonia sufferer. I find that a lot of people's preferred ASMR enjoyment kinks are actually my trigger sounds, but the ones that aren't tend to relax me.

  35. Ok, this comment is not PG13: to make love we need blood to be pumped in our love stick, that blood is pumped by the earth …. usually the brain mess things up like making you thing about your ex while your doing the deed with your wife (or your neighbour wife) …..

  36. Get a good look on your own countries and the government is going through a very strong relationship between you two to one or more people in your country or you have to do it AGAIN in the future you can get the best time to do that and then do something to the people who have the best time ever to get the job and you will have to put it on your hands to get it right now dads and your parents are not going through the same day as you do to your children or your family and friends or friends

  37. I suppose these would be good content for newer members but it's a long time viewer these long-ass videos of a bunch of content of already seen is really annoying

  38. I know this is a compilation video, and the clips are not necessarily recent, but I just want to say here that all of you hosts have really improved in presentation

  39. If my barber started whispering like that I'd get the heck out of there because I'd be afraid he was going to go all Sweeney Todd on me. That's just creepy.
