9 Groundbreaking Discoveries About Sleep

He said sleep so many times it doesnt sound like a work anymore

They have them rats hell

Poor rats...

Poor rats, had a tough time in the 70s

The blue light thing...
So if you look at images of Sonic the hedgehog or Mega Man on your phone, they would disrupt your sleep?

Can the show do a video on: "The importance/use/purpose of [the] tags on clothing"- Courtney L.

4:21 you know, for a doctor who has aided research on sleep, he really doesn't look like hes had much of it.

WTF are these horrifying people doing to these poor rats. I mean....good god.

Why do a lot of kids grind their teeth in their sleep?

How does sleep play into depression? I've read articles about how too much sleep can lead to an early death. But if depression is an illness how does that play out.

What about the guy who lost the ability to sleep,but was wayyy more efficient at doing things?

This is click bait, when I heard these discoveries, the ground beneath me didn't break, I'm so pissed 😡 this click bait is wrong. Stop the click bait.

Can medication help people with that type of insomnia?

It would be nice if the word "believe" could be replaced by "think". For instance "that discovery led scientists to think that sleep is..."

number 7 he says with that background.... with my screen on max... in the dark... i should go to sleep

Poor rats 🐭.

my favorite activity is sleeping

my braining is learning about it self.....thug life😎😎😎

Perhaps the biggest myth, is that you're unconscious when you're asleep. Not so; you're just in a different state of consciousness. You will respond to a crying baby, phone, an itch, pain, alarms, someone trying to break into your house, etc..

"Rats had a harder time healing burn wounds" I wonder how did they tested that poor fellas

Oh man, poor rats.

why is that spot below his throat censored?

talking without pauses is kinda difficult to listen to

if this whole video is about sleep, why didnt you guys talk about too much sleep?

What about sleeping too much?

Ancient humans couldn't get much sleep - plagued by parasites & biting insects, uncomfortable nests or sleeping on branches, having to keep one eye open for tree-climbing predators (like leopards, pumas, snakes, etc.) - all of those survival issues meant they couldn't get a good night's sleep very often. Even cave dwellers had to deal with bugs, snakes, scorpions, etc.

Oh, poor little rats...

why have scientists been burning rats?? 😔

nothing groundbeaking here

Is too much sleep bad for you?

I want to record my dream while im having a wet dream

I thought when I was a sleep my sole would. leave my body. -_- .?dose that really happen

I thought when I was a sleep my sole would. leave my body. -_- .?dose that really happen

I fell asleep to this and i have ridiculous insomnia. hahah

I sleep up to 10 hours per day and I'm very pain sensitive. I wish I could find out if I'm simply sleeping wrong or need even more.

What's in my tears

Is he seriously going to say scientists don't know why we have to sleep. Isn't it obvious?

People actually get paid to work in a lab electrocuting rodents.

Currently watching this at 4am.. (:

My uncle played angry birds epic 48 hrs straight.. he did not die YOU LIEED

Was the host wearing a TRIFORCE t-shirt?

after seeing the background pic at 6:05, insomnia may be a problem tonight.. Also, Uberman? Where does that fit? I read somewhere where people were on that schedule for 6 months+

Sleep = memory consolidation, and astrocytes cleaning out your brain because you know... the BBB is pretty tight. Generally everything else that you stated in this video is in response to this. Hopes this helps people that like facts. Sleep doesn't use a pain system, you have a little guy in your brain that paralyzes you PAG, Periaquaductal Gray I think (been a while since 1st year of medical school)... Everything uses the same pain system because it uses your pain fibers and your pain tract. Until you get into the CNS pain that you have to use weird things for... but I'm going on a tangent.... Memory consolidation, astrocytes. Just go with that and no one in science/medicine will ever question what you say.

Edit: I just got to number 8.... and realized he said Astrocytes lol... Whoops...

whenever go hiking and i only get like 4gours of sleep in the forest i wake up feeling more rested then i wuld ahve if i was at hme gettig 8hours

Guys I'm very close to dying I got to sleep at 1:00 and wakeup at 5am. No wonder why I can't remember shit and I have Chronic Neck Pain. I'm going to sleep before it becomes my last time.
*Good Night*

Lmao and im watching this video at 3am...

The horrible shit we humans did to animals for science.. We owe Rats in particular an apology. God will punish us all.

10:05 Milking a cow!? Did I guessed it?

"-a region of the brain called the hippocampus."
First thing I think of
PERCY JACKSON
I actually didn't know we had hippocampi in our head.
Hmm... I'm calling mine Rainbow.

my friend believed that his classmate can be awake for a month without sleeping

Lmao, when I first clicked on this video, I thought it said "9 Groundbreaking Discoveries About SHEEP" Counting sheep lol?

Rats everywhere

I didn't sleep for 6 months straight, once. I went insane, eventually landing in the local loony bin. It was hell. Doctors never figured out, or never admitted, why. I'm positive it's because they kept trying new drugs on me and I just kept reacting badly. After 3 months I had to start refusing because I just couldn't take the side effects, anymore. 3 months after that, I finally slept... Hmm

I had to reschedule a back tattoo I had going once, because I didn't get any sleep the night before. It was ten times more painful than usual. After an hour, I just couldn't take it anymore. I was shocked how much of a difference that made.

I don't understand how "we don't know why we sleep" but 30 seconds later he says we sleep so our body can rest. Isn't that the reason why we sleep? Someone please clarify

Why are we so mean to rats?

What's funny is that I'm watching this to force myself not to sleep.....

The hippocampus, where all your memories about hippos are stored

You can use blue light filter apps to use your phone during night without disrupting your sleep cycle.😀📱

Good video! ?Could you please do a video about dishwashing? Sounds mundane I know, but my partner and I are having controversy over hand dishwashing vs dishwasher machine and the temperature of hot water. I say sterilizing hot water has to be at least 165degrees F in which you could not handwash dishes because it's too hot. However if you handwash the dishes with a good soap well, rinsed in cool water the dishes are just as clean if not better than in a dishwashing machine. Sterilizing dishes in a machine is OK but wouldn't you also have to keep them in a sterilized environment? Thank you for sharing. Keep up the good work.

it'd be hard to discover all of this stuff without animal testing.

i think wifi interferes with sleep

watching cat videos in the middle of the night?? meeen i did it sometimes

I have horrific iretractable chronic pain which is not fibromyalgia. it is exhausting and I need to take a nap in the afternoon and I need 10 hours sleep at night or the pain explodes beyond what I can stand.

I dont sleep cuz sleep is the cousin of death *thug life music and glasses then dies*

So being in non-REM sleep is where your brain files away and stores what it deems to be important while REM sleep is the brain saying "Fuck it, let's run some simulations 'cause we're bored"

Dont look at devices a few hours before bed... yet im watching this before bed. i wouldnt have learned that unless I was exposed to blue light now..

It seems to me a bit naive to say "we don't know why we sleep" and on the other hand being so certain about all of the counter effects of not sleeping. Could it not just be that your body does that (sleeps) so that those terrible, fatal counter effects don't happen? Could it not be that your body knows (in a very broad sense of the word) that those effects will occur and thus intends to prevent them by sleeping?

I mean the guy in the video says, we don't know why we sleep... and then immediately after he says, a lack of sleep will literally kill you....

So maybe we sleep so we don't die?

Ok. Good night.

I have f.lux on my PC and Night Shift on my iPhone, but I use my iPad the most in bed and it's old enough that it doesn't have a Night Shift. How do I make it do the orange light thing?

poor rats :(

Man youre crazy i sleep with lights on and my phone on a youtube playlist the whole night with 2 pillows and a giant blanket over my head. Its pretty comfortable and i would much rather have that than pitch black and quiet and listen to my ears rinning and think the monster from russian sleep experiment or the devil with no eyes and blood is staring at me waitting for me to move and shit my pants jesusCHRIST

Thank you for this. All my life I've been a chronic sleep avoider, seeing it as wasted time. My loved ones will be happy to hear that you have managed to convince me that sleep really is necessary and mandatory. Cheers! 🙂

the poor rats

I really had no idea that fibromyalgia was worsened by lack of sleep. It really does correspond to my pain levels when I cannot sleep and I cannot do much the next day due to pain and fuzzy brain and lack of motivation. This pain builds up if I do exercise during a bad a day and then keeps me awake the next night because I cannot find a comfortable position. So...if I can somehow sleep then I can feel better and break the cycle! Thanks for the info! I am going to have to stop looking at my phone in bed and just listen to audible or white noise and maybe magazines, catalogues or crossword puzzles, even though that means I leave a light while I am fall asleep. Ok, giving this a try. Amazing!

Wait, number six, there was somebody who purposely burned mice, then purposely deprived them of sleep for the purpose of "study"? Sounds like some areas of science is where the crazy people hide to stay out of trouble with society and the law lol.

Here I am, watching a YouTube video on my iPad right before bed time.

Don't we sleep because we're tired of doing shit all day???? I thought it as common sense

All those dead rats. RIP.

Anybody ever tried meth ? Holy fuck! , 80 hours without one wink of sleep . That shit is crazy I don't how people can keep doing that stuff .

Am I the only one thinking in the miserable life the rats in those studies had..?

where did you get your shirt?

Poor Rats they take so much @&$% so we don't have to. They definitely got the short end of the stick

Who else is procrastinateing sleep staying up late watching YouTube videos!

Love the article. Great content! -- BUT THE FASHIONABLY-OVERUSED COMPRESSED CAPITAL TYPESETTING FOR NON-TITLES IS DISTRACTING AND HORRIBLY IMPLEMENTED AS ANNOTATIONS. BEST RESERVE FOR TITLES ONLY -- Still I loved the content! Thanks for this!!

" still running in the family* but they keep reproducing, such genes to protect ...

"Sleeplessness makes pain worse." Seems reason enough for getting sleep, fwiw

So how do you explain most of the time set the alarm clock and most of the time you wake up maybe 5 minutes early!!!!

is it just me or is Hank's voice a little raspy?

Anyone else watching at 3am?

Why are you fidgeting and using hand gestures so much? It's random; like your just fidgeting just to fidget. Plus it's annoying. until you can tone it down, in unsubscribing.

My wife and two children have FFI. This mutation is trying to take everything I love. Is there any breakthroughs anywhere? Vanderbilt didn't have a clue what we were even talking about. The dr didn't even take the time to google it

8:05 Wrong kind of cat video, guess again.

Aw those poor rats, what a way to die. Sleep deprived to death...

I could use some sleep

If you take one thing from that video it should be: don't get reincarnated as a rat!

eeg isn't a new technique at all. wait.... how did I get here. I need to sleep.

So....we're Rats now ?😂

Here's what I think are the two most important facts about sleep: The fact that sleep is necessary and how much you should get
