Fun fact: people didn't always do one big sleep. We used to go to bed when the sun went down. Slept for several hours (3-5) and then rise, eat something or go for a walk. Then you'd go back to sleep until morning. So if you read old stories and they talk about a second sleep...
That is what I've found my natural sleep pattern to be. Thought I was just "weird". THEN I learned about this, and I'm all like "What the HECK are we doing to ourselves??"
That is how I sleep. Have for twenty years. I suffered profoundly from insomnia until I read about and adopted this technique and now I just accept it and go with the flow fortunately my schedule alows for this. I wake and sleep as needed without regard to schedule.
"You shouldn't use electronic devices for 1 hour before sleep." Okay, I turn off my laptop at 4 AM. What the heck should I do for another 1 hour in the dark?
Sebastian you just took me back many years. I remember being around 13-15, waking up in middle of the night, to take a leak. Looking at time when I get back in bed. Only to see it's 3am and I have 4.5 hours left to sleep before waking up for school.
I play all of hanks videos on a playlist on shuffle I made. Its helped with my insomnia so much. His voice is very enjoyable to my ears and his facts keep my mind occupied from my bad thoughts.
That dream didn't sound very reassuring, either. You deliberately awoke yourself from an understandably terrible nightmare and apparently your body wasn't ready to follow you--; since it still kept your motor-pathway, shut-off--. Dreams as bad as this one sounds--; tend to be warnings--. It seems to me to be about where maybe nobody in your life might be worth trusting, meaning, about almost "anything--;" not just "that--.'. It could be a warning that a lot of people have shot you veiled innuendo about the thing you described--; but which you didn't catch, in the moment--. Hopefully, I am just "wrong" about both of those things. But it wouldn't hurt to look at it, I'm thinking--. I hope things stay okay--. Thank You--.
I had the same thing happen. My ex partner assaulted me, and a little over half a year with my current girlfriend (two years now and it still happens), I would wake up and have extreme sleep paralysis. I would be completely paralyzed, crying and having an internal panic attack after the dream, and she would just sit there soothing me and making sure I was okay. The dreams have stopped, thankfully, but she seriously helped me by just rubbing my hand and making sure I was okay.
As a stay at home mom (for now) yes, I get sleepy around 2 pm (always have, even when working), but I take a nap for about an hour or an hour and a half. I still go to bed around 11, and get up around 7:30. It seems to help me tremendously.
Oversleeping may be tied to undiagnosed Sleep Apnea, which I think is fairly common. And untreated Sleep Apnea definitely causes increased blood sugar, blood pressure, and other bad things.
I don't have any kind of sleep pattern . My husband , is totally different . When he lays down and puts his arm over his head . ...he is completely asleep within 2 minutes . The very truth . We have been married for 46 yrs and he has always been this way. Lucky for him.
I'm suprised Hank didn't mention the 'Old Hag' phenomenon! A hugh amount of people seem to have a common 'hallucination....upon awakining they often can't breath because of a horrid old woman hovering over them in a menacing manner! Ascribed to 'wakeful dreaming'...ummmm...In my 70s acid culture we had a belief that during LSD trips if more than one person has a hallucination...it's not!!!
Hey SciShow, could you put something in the title that indicates that a video is a compilation or a review or something? As a longtime viewer, it's a bit disappointing to be notified that there's a new video, only for it to be a bunch of videos I've already seen before.
Rok Pušnik This. I often background videos so I may not be paying enough attention to realise until a ways in unless something obvious happens like the speaker changing
I knew it was a compilation of videos from just looking at the title. If you look at the single episodes, then look at compilation videos, it's not too difficult to tell the difference because of the titles are written different between the single and compilation videos. Also, the thumbnail shows the time and I kinda like these compilations. It's a good refresher video.
Sleep Paralysis has happened to me twice. First time it was kind of the classic pressure on chest, feeling of terror and feeling of a malicious presence. The second time it happened though, I had already learned about it. So when I realized what was going on, I swore in my head, laughed and then fell back asleep.
I saw a guy looking in my window a week ago in a cut-away vision....a friends says i have a ghost. Donna told me i weigh 168 pounds. She says ...howdy ya all!
I was stuck in my sleep, feels like someone superficial entered my body , my body was literally locked, I was sweating, I can feel everything but couldn't move ? What was that ?
I NEEDED THIS VIDEO! Thank you so much this was incredibly informative and helped me realize my own issues involving sleep. I feel a lot better about my conditions and I believe it's because of my super messed up sleep schedule/cycle. I need to FIX my sleep.
There was this odd time when it felt like I was half-asleep… in a very literal way. I felt like a dozed off in class one time and those I was watching what was happening around me and more or less understanding what was going on, I also was having a dream about my grandparents. At one point I start seeing more of my dream then the waking world, but the thing I’m hearing in the waking world is still being registered; so it appeared as if my grandparents were talking with the voices of my classmates.
Why do I feel warmer after sleeping than before? My house is the same temperature when I go to bed as when I get up in the morning, but I always feel chilled in the evening before bed, adding sweaters and fuzzy socks that I would be way too overheated to wear in the morning. Is it just based on metabolic rate, or is there more going on?
It’s recommended that you sleep with little to no clothing because your body finds it very difficult to perform homeostasis (maintaining a stable temperature) while both sleeping and wearing clothes. So maybe try to get warmed up before going to sleep? Hope this helped, it definitely helped me!
It's because our bodies need to drop temperature slightly to fall asleep - so I imagine we feel cold when we're tired because it's our body protesting our forced awake state...and then when the body is ready to wake up, our temperature rises back to normal to wake us up. I'll try and find the link for the lecture I learned that from :)
Because of something called Osmosis. You sleep with a blanket and the environment of the blanket and the space inside it becomes warm with time like a radiator. It takes a little while for the heat to become more dispersed. The warmth of your body heats up your environment and a blanket makes it stay localized for longer. It's more thermodynamics than biology.
Thank you for this video. I have Asperger's and associated genetic insomnia, so I'm always looking for a better understanding of the complicated processes involved with sleep, or lack of it.
I feel your pain. Mine wasn't full-blown but I got on average about 2 hours before I just woke up and couldn't get back to sleep. And those 2 hours (average) were after laying, doing nothing, for about 5 or more hours. So, not as bad as some but I kinda get it. Thank God for prescribed sleep meds.
I have mixed sleep apnea (obstructive sleep apnea + central sleep apnea). When I found out what central sleep apnea was, I said "Oh, so my brain is trying to kill me?" My doctor said "I wouldn't call it that, but...yeah." When I had my sleep study, the nurse said I had the highest number of apnea events she'd ever seen. (Whee! I win! lol.) My AHI was 143. (I stopped breathing 143 times per hour.) Mine is treated very well with an ASV (Adaptive support ventilation) machine. That's a CPAP machine that also forces air when you stop breathing. It's a non-invasive ventilator. I now sleep like a baby. Well, probably better than a baby. Babies wake up a lot. Treated with ASV, my AHI is now like someone without apnea (AHI of less than 1 to 3. Less than 5 is normal.) A lot of people hate when they get on CPAP, I loved it. It basically improved my life 1000% starting with the first night, about 5 years ago.
Great video about sleep guys. As a person who has suffered with Chronic Fatigue Syndrome, Fibromyalgia & other fun problems I am not one to skip a nap when my body asks for one. I had a very, very tough time adjusting my circadian rhythm back to a 'Normal' Daytime rhythm. But now days I'm up before the sun usually and to bed & asleep around 10 PM. I still bring my phone with me to bed to watch videos, but now days there's a way you can remove the blue light on the phone to prevent issues. I for one am thankful for that. Hope everyone at SciShow had a wonderful Thanksgiving! 🦃💞🥂
I always thought my sleep paralysis were instances of feverish hallucinations! In my case the panic and anxiety/confusion was about being stuck in that inbetween state (not fully awake or fully asleep). I often lucid dream so having sleep paralysis frightens me because unlike nightmares I wake up when sufficiently freaked out. Instead the anxiety and stress grows because I'm aware of my physical situation which I can't control (lying in bed/can't move) The worst is when it's accompanied by vivid visual hallucinations. These hold me hostage to the point I'm convinced that I can only be freed once I complete a nonsensical or ridiculous "mental task". The most vivid one I can remember was having to build a child meccano set. All the pieces were laid out in the air. Despite it being child's play the task seemed so impossible and as confusing as rocket science (for a non scientist). The hope of fully waking up or going to sleep were just out of my reach since according to the hallucination I just absolutely had that responsibility to build it until completion.
10:09 I actually had this happen to me a few years ago. For reasons never determined, I went about five days without sleep, and by day three, I had completely lost the plot - except for “Downton Abbey’s” plot, because for some reason I thought that was real and was begging my now-wife to go help Anna the maid. I was also absolutely convinced my wife had let someone in the house and was lying to me about it. It was bad enough my (now former) doctor was actually going to have me committed to a mental health facility on a 72-hour hold. (Why he didn’t just write me a script for a sleeping pill just to kickstart my system was also never determined, nor why no OTC meds or even alcohol, which tends to make me sleepy, didn’t work.) It only ended when my body basically just shut down, I guess; apparently, I walked back to our bedroom, laid down and was out for the count. I don’t remember much from days four or five, and despite having survived 17 blood clots thanks to an aggressive and incurable genetic disorder, I’ve never been so scared or ashamed in my life as I was after that experience, and to this day feel absolutely terrible for what I put my wife through. I’m even more terrified of it happening again. tl;dr screw you, locus coeuruleus
i can! it was before i became an alcoholic. back when my body's hydration wasn't being completely depleted 4-6 hours into my rest. unfortunately, it's a difficult habit to break.
Well, that's obvious, isn't it? Your dad's in an American prison and will never get out, you and your family are on the run, and your constantly having to fight off the next Narco Kingpin of Central America? AmIRight? I'm right, aren't I?
It *is* also true that each person has different sleep needs. And, for some folks, it's simply not possible to stay in bed for eight hours; for myself, it's just not possible to rest when your back and joints are screaming at you to get up and move.
My sleep problems started me convinced that it simply had insomnia. I had the pattern of nights of believing I was staring at the ceiling all night, then after a few nights of that, I would finally sleep through the night. On the nights I was sleeping, I realized I was waking up around 20+ times a night. I kept a notebook in my bed and every time I roused, I put a check on the page (I did not turn on the light). In the morning, I counted the checks. My doctor sent me to a sleep specialist who ordered a sleep study. I thought I had insomnia that night only to be shocked to find out I had been in and out of sleep during that time. I never went into deep sleep or REM sleep, when I began to have sleep apnea in stage two, my body roused me to keep me breathing. I was sleeping 10 minutes at a time before waking up--and since I was not aware that I had dropped off to sleep I thought I was not going to sleep at all. The second half of the night I has a CPAP mask on and the technician was trying to determine the proper pressure for me. She ran out of night, however when she got me around half of my therapeutic pressure, I dropped into REM sleep and stopped breathing 53 times an hour. Close to once a minute. No wonder I was not getting to a deep sleep. With the CPAP machine at the proper pressure level for me, my apnea incidents are around 2or 3 an hour. What a change!
If you can, get in bad 9 hours before you need to get up. 15 minutes to fall asleep, 8.5 hours to sleep, and 15 to press snooze or whatever of that sort
I've had sleep paralysis so many times now that even my sub-conscious brain is used to it. Like, when there some creepy nightmare figure sitting on my chest telling me that its going to burn my house down, my half-dreaming self is all, 'Cool story, dream hallucination. Just wait for my brain to catch up with me and then we'll see who ceases to exist.' It's actually oddly satisfying.
I've nocturnal epilepsy. A side effect for some sufferers is that they've trouble falling asleep and keep waking during the night. If you have epilepsy, sleep is reeeeeally important to stop seizures so, not good. I ended up anxious and scared about sleep which made things worse so I was put on a second seizure drug especially made for people like me - it's basically a sedative. I've never been happier and now happily sleep for 10 hours straight!
Do the best you can to get yourself a better sleep pattern. Do this for yourself because it will help you not get PTSD from the stress and trauma of your job.
Years ago after my divorce I had never been on my own before. I went from living with family to a husband and/or kids. I was in my 40s living in my first apt. I had alarms on doors/windows but every night I was hearing someone moving around in the kitchen. I wasn't sleeping well, I was working full time and going to college full time. I was going into paranoia and no one could tell me why I was hearing someone in the kitchen but night. The dr. gave me amitriptyline and after the first really good sleep I was able to understand I was actually hearing the heating unit located in the baseboards of the front room & kitchen. Amazing what a good night's sleep can help and my goodness what we undergo when we don't get it!
I have heard of ONE study done that removed the sun from the equation. They studied one woman who cut herself off from outside regulatory stimuli (including the sun, clocks, etc.), and she started living on a natural schedule that was LONGER than 24hrs by a few hours. Unfortunately, I don't know that I could find that study again to link it to you. But that's the closest I've heard of any study done on anything close to Arctic/nocturnal conditions.
Haha, I usually wake up around 3:30 or 4 o'clock. AM. Without an alarm. I also fall asleep on the computer ALL the time. I fall asleep running youtube videos, too.
I just experienced sleep paralysis last night. It felt like hours before I could move even slightly. I was finally able to sit up but not move anymore. It was pretty scary IMO. I felt so anxious
You can turn down the output level of a video screen in a dark room with curtains drown. This way the eyes will also be adapted to walking around unlit rooms.
Yeah, well, since I was five years old, a huge cup of coffee with little or no sugar has always been a sure-fire way for me to be unconscious within and hour. Caffeine - puts me to sleep. Even better than alcohol.
I've found that when I have sleep paralysis it helps to do math problems or trying to recite books and poems. I don't know why but my guess is that forcing your mind to wake up may help stop the paralysis.
The first half of the night is spent relieving sleep pressure, the second half is more concerned with the brain. Glutathione is a redox buffer that regulates ATP production in the mitochondria. I have been using liposomal glutathione for about 20 months now. I "suck" 2 - 4ml in the morning and I find that my REM sleep is greatly improved. I used to wake at 4am and not go back to sleep, now I awaken after 7 - 8 hours of nutritious sleep, usually after an imaginative dream. I'm trying to spread the work, I want people to study this simple treatment further
What I can't understand, but really pisses me off is that my alarm keeps waking me up in the wrong sleep phase. Sometimes, I wake up earlier and feel halfway decent, but then try to get 2 more hours of sleep until my alarm goes off and then I feel horrible once I wake up again!
I realize this is an old comment, try to sleep in increments of roughly 90 minutes. The full sleep cycle is much easier to wake from; waking mid cycle is downright painful! So if you have 2 hours, sleep only 90 minutes of that. If you still wake groggy, try 95 or 100 minutes next time. Play around with it til you find your sleep cycle. I promise it’ll help!
While I nodded, nearly napping, suddenly there came a tapping, As of some one gently rapping, rapping at my monitor. “’Tis some video,” I muttered, “SciShow on my monitor- Only this and nothing more.”
So what about people with naturally longer or shorter circadian rhythms, regardless of light exposure? Or "night owls" who generally function more effectively later in the day?
Sleeping, I've practiced dying for years. I'm pretty sure I have it down now. Wait, nvm, I woke up again. Guess I gotta practice more. Time to sleep again.
I have idiopathic hypersomnia, narcelepsy without the cataplexy... (I dont just pass out into my soup) instead of out of no where passing out I go into the feeling that feels like you just took 2 sleep aids and drank some chamomile tea . . I just pass out slowly or fast sometimes , what's worse is it happens all day and night obviously where it's literally me goig in and out in and out in and out of that feeling and if I can't control it myself which is an extreme challenge , then I go straight into sleep paralysis.. sometimes i fall asleep but it was 80 percent more of going in and out if sleep paralysis all day every day , i have 2 young boys who need me bc we do not have anyone who helps me with them. The family helps when they feel like it and it's extremely rare .. very very rare . I dont know how or what makes me pull myself up and out of it but if I heard one of the boys crying or needing me I would still be fighting myself to get up , bci still was awake just looked asleep and body was asleep but I was wife awake in my mind other than still having the feeling of sleepiness but once in paralysis it was as strong as it is when not, but anyway I call it a miracle that I would be able to get out (not without a quick panicking fight with myself of course) but I am able to come to ignore of the boys needed me or if I heard them cry, only thing I can think of as to why I am and was able to do that is due to it being something similar to a mother lifting a csr off her child and I say that bc I was more able to pull myself out for then than I am for myself. If I'm by myself and say was driving or something where I shouldnt be sleeping for health or safety reason or reasons like not lose my job that I loved.it just didnt matter I barely was ever to so it for myself I lost my job cant hold one and I'm literally on 3 stimulants a day and they are at very high mg. I still have problems even with meds but no where near as bad the adhd it causes sucks to. It's just a complete mess. Its just a complete total crazy and unbelievable mess of a disorder. Its just so mindfkkng especially without meds. Lord god I am thankful for the meds . Everyday life is a struggle but you know what . I am and think of myself to see it as still a huge blessing to have compared to how messed up a disease or disorder I coudl have bc I'm still able to have my mind with it just on a diff. Level than the norm. Same with my bone disease and back and leg problems. Regardless of everythig messed up , I am still able to be physically able just not as well as most and not as pain free, but I still can do everything i want to within limit so still a huge great big deal to me that yeah I like many others do have something disabling going on with us but we all need to stop and remind yourself of how much we could not have or have wrong . I have no pitty for myself either btw. .. hope I didnt bore anyone too much and if you think I wrote to much and want to be an as* well then look who's truly doing too much , if you take the time to whine or make a lame "funny" when looks like you would be the one who outdid themself. 😁 just count your places everyone .. actually don't count them. Just appreciate them and keep it going 😊
What?... I am watching a video in which a man is falling asleep while driving, it is 2 a.m. here and I got a notification on the science of sleep... I think the universe is telling me to go to sleep... Lmao.
Anyone else sleep so deep that you can wake up walk around, converse with people, go back to sleep and not even know it happened? No? Ok than just me...
Are you here because you can't sleep? Me too. So I'll share some quick facts I've learned from reading way too many studies about sleep while I can't sleep: 1. Since this video, we've discovered why we sleep. It's so your brain can clean itself out. Google "glymphatic system". 2. Temperature may be more important than sunlight (or lack thereof) on your ability to sleep. Your body temperature needs to drop a few degrees to initiate sleep. Try taking a hot bath or a long hot shower 2 hours before bed to jumpstart your body's cooling process. Google "body temperature sleep". 3. Being bored for an hour before bed can help you get sleepy. 4. I need sleep, so I can't think of anything else. Do you believe that thing about caffeine at 13:20 or do you think that people who don't sleep enough are going to be more reliant on caffeine during the day because they can't sleep? I mean, I get that you shouldn't have it in the few hours before bed. I'll even grant you after lunch. But 12 hours? Maybe if you're the kind of person who takes a Benadryl and is out for 2 days. 5. Go to bed.
I've only experienced sleep paralysis a couple of times, and it's terrifying, you're awake but can't move and I saw a shadowy figure leaning over me and pressing on my chest
Thank you for this video. I have Asperger's and associated genetic insomnia, so I'm always looking for a better understanding of the complicated processes involved with sleep, or lack of it.
13:53 oh this happens to me a lot. I think I just closed my eyes and slumped my head for a second, only to wake up and be told I was out for half an hour
I was an only child up until the age of 8. When my sister was a bit older than a baby (I think she already started walking), my parents put her bed in what was my room. I started sleepwalking. Loooking back, I think it was stress, but I never resolved it. I started to sleep a lot better when I got my own room again (when I was 12 or so).
One time i had sleep paralysis. I fell asleep watching youtube and i opened my eyes but couldnt move. And a huge "spider" crawled towards my face. I closed my eyes again and was able to move. Ripped my bed apart looking for said "spider" until i realized i had just experienced sleep paralysis for the first time.
Me at 3am: I should be asleep but instead I MUST LEARN THE SCIENCE OF SLEEP in order to sleep better of course...
Lol
Didnt help. Got confused and watched 30 episodes of one piece. Now even more sleep deprived.
Me at 3am: Normal bed time in 1 hour. Normal wake time is noon. Playing tablet has no effect on sleepiness. Sun makes me sleepy.

What most usually keeps me awake past bedtime is watching youtube videos like this one; it's an addiction.
HEY dont just try to walk past the fact that part of your brain is blue
I NEEDED THIS VIDEO! Thank you so much this was incredibly informative and helped me realize my own issues involving sleep. I feel a lot better about my conditions and I believe it's because of my super messed up sleep schedule/cycle. I need to FIX my sleep.
There was this odd time when it felt like I was half-asleep… in a very literal way. I felt like a dozed off in class one time and those I was watching what was happening around me and more or less understanding what was going on, I also was having a dream about my grandparents. At one point I start seeing more of my dream then the waking world, but the thing I’m hearing in the waking world is still being registered; so it appeared as if my grandparents were talking with the voices of my classmates.
I’m going to go ahead and get my 25 years of sleep over with now so I don’t have to worry about it in the future, I’ll see you guys in 2043 ✌🏻
24 more years to go
You'll be in so much pain when you wake, better hire a service to roll you 4x a day and work all your joints 2-3x a day.
Hope you slept through 2020

I stayed up for more than 24 hours playing video games recently and towards the end I started hearing music that wasnt there lul
Why do I feel warmer after sleeping than before? My house is the same temperature when I go to bed as when I get up in the morning, but I always feel chilled in the evening before bed, adding sweaters and fuzzy socks that I would be way too overheated to wear in the morning. Is it just based on metabolic rate, or is there more going on?
It’s recommended that you sleep with little to no clothing because your body finds it very difficult to perform homeostasis (maintaining a stable temperature) while both sleeping and wearing clothes. So maybe try to get warmed up before going to sleep? Hope this helped, it definitely helped me!
This happens to me too; being tired makes me feel chilled.
It's because our bodies need to drop temperature slightly to fall asleep - so I imagine we feel cold when we're tired because it's our body protesting our forced awake state...and then when the body is ready to wake up, our temperature rises back to normal to wake us up. I'll try and find the link for the lecture I learned that from :)
@@elitecabela5329 good advice. Winter campers would be familiar with this. Sleeping with clothes on swings your temperature from hot to cold too much
Because of something called Osmosis. You sleep with a blanket and the environment of the blanket and the space inside it becomes warm with time like a radiator. It takes a little while for the heat to become more dispersed. The warmth of your body heats up your environment and a blanket makes it stay localized for longer. It's more thermodynamics than biology.

Thank you for this video. I have Asperger's and associated genetic insomnia, so I'm always looking for a better understanding of the complicated processes involved with sleep, or lack of it.
I wish napping during the job would be allowed....
John Doe Hilarious comment mate!!
It is in Japan, maybe other countries too
@John Doe how often have you spammed this video? All the Hanks in this video are old, so of course they don't match the modern UA-cam aesthetic
God no, i don't want to be at work longer for ANY reason, not even sleep.
I've always been a supporter of napping at work .... but I couldn't even manage to get an uninterrupted half hour lunch.
Video comes out on the brink of my insomnia relapse, this should be fun
I feel your pain. Mine wasn't full-blown but I got on average about 2 hours before I just woke up and couldn't get back to sleep. And those 2 hours (average) were after laying, doing nothing, for about 5 or more hours.
So, not as bad as some but I kinda get it.
Thank God for prescribed sleep meds.
I have mixed sleep apnea (obstructive sleep apnea + central sleep apnea). When I found out what central sleep apnea was, I said "Oh, so my brain is trying to kill me?" My doctor said "I wouldn't call it that, but...yeah."
When I had my sleep study, the nurse said I had the highest number of apnea events she'd ever seen. (Whee! I win! lol.) My AHI was 143. (I stopped breathing 143 times per hour.)
Mine is treated very well with an ASV (Adaptive support ventilation) machine. That's a CPAP machine that also forces air when you stop breathing. It's a non-invasive ventilator. I now sleep like a baby. Well, probably better than a baby. Babies wake up a lot.
Treated with ASV, my AHI is now like someone without apnea (AHI of less than 1 to 3. Less than 5 is normal.) A lot of people hate when they get on CPAP, I loved it. It basically improved my life 1000% starting with the first night, about 5 years ago.

sleep is for the week

@J L well its top comment cuz people like it
Great video about sleep guys. As a person who has suffered with Chronic Fatigue Syndrome, Fibromyalgia & other fun problems I am not one to skip a nap when my body asks for one. I had a very, very tough time adjusting my circadian rhythm back to a 'Normal' Daytime rhythm. But now days I'm up before the sun usually and to bed & asleep around 10 PM. I still bring my phone with me to bed to watch videos, but now days there's a way you can remove the blue light on the phone to prevent issues. I for one am thankful for that.
Hope everyone at SciShow had a wonderful Thanksgiving! 🦃💞🥂

Green: People often feel sleepy from 2 am to 4 am and 2 pm to 3 pm
Me watching this half asleep at 2:30 pm: 💤
I didn't realise how much Hank jokingly complains about streaming until this video XD
I always thought my sleep paralysis were instances of feverish hallucinations! In my case the panic and anxiety/confusion was about being stuck in that inbetween state (not fully awake or fully asleep).
I often lucid dream so having sleep paralysis frightens me because unlike nightmares I wake up when sufficiently freaked out. Instead the anxiety and stress grows because I'm aware of my physical situation which I can't control (lying in bed/can't move) The worst is when it's accompanied by vivid visual hallucinations. These hold me hostage to the point I'm convinced that I can only be freed once I complete a nonsensical or ridiculous "mental task".
The most vivid one I can remember was having to build a child meccano set. All the pieces were laid out in the air. Despite it being child's play the task seemed so impossible and as confusing as rocket science (for a non scientist). The hope of fully waking up or going to sleep were just out of my reach since according to the hallucination I just absolutely had that responsibility to build it until completion.
This quarantine really disturbed my body's rhythm and I am watching this @ 6:21 AM without/can't/won't sleep anytime soon. I miss sleeping 😭
10:09 I actually had this happen to me a few years ago. For reasons never determined, I went about five days without sleep, and by day three, I had completely lost the plot - except for “Downton Abbey’s” plot, because for some reason I thought that was real and was begging my now-wife to go help Anna the maid. I was also absolutely convinced my wife had let someone in the house and was lying to me about it. It was bad enough my (now former) doctor was actually going to have me committed to a mental health facility on a 72-hour hold. (Why he didn’t just write me a script for a sleeping pill just to kickstart my system was also never determined, nor why no OTC meds or even alcohol, which tends to make me sleepy, didn’t work.) It only ended when my body basically just shut down, I guess; apparently, I walked back to our bedroom, laid down and was out for the count. I don’t remember much from days four or five, and despite having survived 17 blood clots thanks to an aggressive and incurable genetic disorder, I’ve never been so scared or ashamed in my life as I was after that experience, and to this day feel absolutely terrible for what I put my wife through. I’m even more terrified of it happening again. tl;dr screw you, locus coeuruleus

I can’t remember the last time I went to sleep and stayed asleep until my alarm went off
i can! it was before i became an alcoholic. back when my body's hydration wasn't being completely depleted 4-6 hours into my rest. unfortunately, it's a difficult habit to break.
Neither can I. Usually because I sleep *through* my alarm.
@@apple54345 glug glug
Same. I usually wake up 3-6 times in the middle of the night and it's really annoying. It's been like that for me for _years_
Well, that's obvious, isn't it? Your dad's in an American prison and will never get out, you and your family are on the run, and your constantly having to fight off the next Narco Kingpin of Central America? AmIRight? I'm right, aren't I?
It *is* also true that each person has different sleep needs. And, for some folks, it's simply not possible to stay in bed for eight hours; for myself, it's just not possible to rest when your back and joints are screaming at you to get up and move.
My sleep problems started me convinced that it simply had insomnia. I had the pattern of nights of believing I was staring at the ceiling all night, then after a few nights of that, I would finally sleep through the night. On the nights I was sleeping, I realized I was waking up around 20+ times a night. I kept a notebook in my bed and every time I roused, I put a check on the page (I did not turn on the light). In the morning, I counted the checks.
My doctor sent me to a sleep specialist who ordered a sleep study. I thought I had insomnia that night only to be shocked to find out I had been in and out of sleep during that time.
I never went into deep sleep or REM sleep, when I began to have sleep apnea in stage two, my body roused me to keep me breathing. I was sleeping 10 minutes at a time before waking up--and since I was not aware that I had dropped off to sleep I thought I was not going to sleep at all.
The second half of the night I has a CPAP mask on and the technician was trying to determine the proper pressure for me. She ran out of night, however when she got me around half of my therapeutic pressure, I dropped into REM sleep and stopped breathing 53 times an hour. Close to once a minute. No wonder I was not getting to a deep sleep.
With the CPAP machine at the proper pressure level for me, my apnea incidents are around 2or 3 an hour. What a change!
If you can, get in bad 9 hours before you need to get up. 15 minutes to fall asleep, 8.5 hours to sleep, and 15 to press snooze or whatever of that sort
I've had sleep paralysis so many times now that even my sub-conscious brain is used to it. Like, when there some creepy nightmare figure sitting on my chest telling me that its going to burn my house down, my half-dreaming self is all, 'Cool story, dream hallucination. Just wait for my brain to catch up with me and then we'll see who ceases to exist.'
It's actually oddly satisfying.
I've nocturnal epilepsy. A side effect for some sufferers is that they've trouble falling asleep and keep waking during the night. If you have epilepsy, sleep is reeeeeally important to stop seizures so, not good. I ended up anxious and scared about sleep which made things worse so I was put on a second seizure drug especially made for people like me - it's basically a sedative. I've never been happier and now happily sleep for 10 hours straight!
i really enjoy these compilations! all videos of an interesting topic nicely packed together into one single video.
I came here to watch a video about sleep, now I'm watching an ad about the lego movie two that is also showing the first movie as the ad in itself.
I’m a nurse, so sleep pattern is basically shite 😑
Best comment! 😂😂
Do the best you can to get yourself a better sleep pattern. Do this for yourself because it will help you not get PTSD from the stress and trauma of your job.
Years ago after my divorce I had never been on my own before. I went from living with family to a husband and/or kids. I was in my 40s living in my first apt. I had alarms on doors/windows but every night I was hearing someone moving around in the kitchen. I wasn't sleeping well, I was working full time and going to college full time. I was going into paranoia and no one could tell me why I was hearing someone in the kitchen but night. The dr. gave me amitriptyline and after the first really good sleep I was able to understand I was actually hearing the heating unit located in the baseboards of the front room & kitchen. Amazing what a good night's sleep can help and my goodness what we undergo when we don't get it!
I've been using a CPAP machine for a year and a half now and have learned that I never knew what a good night's sleep was before using the machine.
amen!
Praise technology!
I feel so called out by this episode :")
SciShow, i need to let you know that I started watching this video and it made me pass out on the floor and sleep there all night
“When we mess with that things can get out of whack in a hurry”
Going in public when your drunk and trying to act sober
I like these compilation videos.
As a person who grew up in Alaska I can't take the whole circadian rhythm idea seriously until someone explains how it works for Arctic peoples.
It definitely applies to the majority. I'm not sure much research has been done on the Arctic effect.
I have heard of ONE study done that removed the sun from the equation.
They studied one woman who cut herself off from outside regulatory stimuli (including the sun, clocks, etc.), and she started living on a natural schedule that was LONGER than 24hrs by a few hours.
Unfortunately, I don't know that I could find that study again to link it to you. But that's the closest I've heard of any study done on anything close to Arctic/nocturnal conditions.
Haha, I usually wake up around 3:30 or 4 o'clock. AM. Without an alarm.
I also fall asleep on the computer ALL the time. I fall asleep running youtube videos, too.
Just clicked this. Super excited to see such a long scishow video
What is harder is getting my cat in sync with going back an hour!

Master Therion ,. Yes! Absolutely. You have a wonderful Christmas.
I have never awakened feeling refreshed. It takes me hours to come around and be normal.
I just experienced sleep paralysis last night. It felt like hours before I could move even slightly. I was finally able to sit up but not move anymore. It was pretty scary IMO. I felt so anxious
This explain why I am so anxious, tired and paranoid all the time.
You can turn down the output level of a video screen in a dark room with curtains drown. This way the eyes will also be adapted to walking around unlit rooms.
Blue light filters also negate the problem almost entirely.
I swear there is not a single bit of melatonin in my body. Falling asleep for me is almost impossible. It takes me like 5 hours.
Yeah, well, since I was five years old, a huge cup of coffee with little or no sugar has always been a sure-fire way for me to be unconscious within and hour. Caffeine - puts me to sleep. Even better than alcohol.
I watch this video about sleeping to help me fall asleep. Works every time
Would’ve appreciated more info on narcolepsy! As a person suffering from narcolepsy I’d love to get more of a scientific explanation :)
Why did u eat my cat ):
Talk to an actual doctor ... smh
I've found that when I have sleep paralysis it helps to do math problems or trying to recite books and poems. I don't know why but my guess is that forcing your mind to wake up may help stop the paralysis.
I find that swallowing my spit is the most efficient way to escape sleep paralysis
strange, i can only do math outside my body.
The first half of the night is spent relieving sleep pressure, the second half is more concerned with the brain. Glutathione is a redox buffer that regulates ATP production in the mitochondria. I have been using liposomal glutathione for about 20 months now. I "suck" 2 - 4ml in the morning and I find that my REM sleep is greatly improved. I used to wake at 4am and not go back to sleep, now I awaken after 7 - 8 hours of nutritious sleep, usually after an imaginative dream. I'm trying to spread the work, I want people to study this simple treatment further
I use a laptop in bed every morning at 4am & fall asleep with no problems. Wake time is noon. the sun makes me sleepy.
Yeah, me too. BuT nOcTuRnAl PeOpLe DoN't ExIsT! 🙄
I have never agreed so hard to something like Michael's intro statement to this compilation.
What I can't understand, but really pisses me off is that my alarm keeps waking me up in the wrong sleep phase. Sometimes, I wake up earlier and feel halfway decent, but then try to get 2 more hours of sleep until my alarm goes off and then I feel horrible once I wake up again!
I realize this is an old comment, try to sleep in increments of roughly 90 minutes. The full sleep cycle is much easier to wake from; waking mid cycle is downright painful! So if you have 2 hours, sleep only 90 minutes of that. If you still wake groggy, try 95 or 100 minutes next time. Play around with it til you find your sleep cycle. I promise it’ll help!
While I nodded, nearly napping, suddenly there came a tapping,
As of some one gently rapping, rapping at my monitor.
“’Tis some video,” I muttered, “SciShow on my monitor-
Only this and nothing more.”
I've always realized that when I studied just before I went to bed I remembered more
So what about people with naturally longer or shorter circadian rhythms, regardless of light exposure? Or "night owls" who generally function more effectively later in the day?
Excellent questions that I also have - seeing as I'm naturally nocturnal. Which is apparently impossible. 🙄
Sleeping, I've practiced dying for years. I'm pretty sure I have it down now. Wait, nvm, I woke up again. Guess I gotta practice more. Time to sleep again.
Sleep ... something I don't get enough of.
FINALLY A SLEEP VIDEO
Nice mandelbrot set
I have idiopathic hypersomnia, narcelepsy without the cataplexy... (I dont just pass out into my soup) instead of out of no where passing out I go into the feeling that feels like you just took 2 sleep aids and drank some chamomile tea . . I just pass out slowly or fast sometimes , what's worse is it happens all day and night obviously where it's literally me goig in and out in and out in and out of that feeling and if I can't control it myself which is an extreme challenge , then I go straight into sleep paralysis.. sometimes i fall asleep but it was 80 percent more of going in and out if sleep paralysis all day every day , i have 2 young boys who need me bc we do not have anyone who helps me with them. The family helps when they feel like it and it's extremely rare .. very very rare . I dont know how or what makes me pull myself up and out of it but if I heard one of the boys crying or needing me I would still be fighting myself to get up , bci still was awake just looked asleep and body was asleep but I was wife awake in my mind other than still having the feeling of sleepiness but once in paralysis it was as strong as it is when not, but anyway I call it a miracle that I would be able to get out (not without a quick panicking fight with myself of course) but I am able to come to ignore of the boys needed me or if I heard them cry, only thing I can think of as to why I am and was able to do that is due to it being something similar to a mother lifting a csr off her child and I say that bc I was more able to pull myself out for then than I am for myself. If I'm by myself and say was driving or something where I shouldnt be sleeping for health or safety reason or reasons like not lose my job that I loved.it just didnt matter I barely was ever to so it for myself I lost my job cant hold one and I'm literally on 3 stimulants a day and they are at very high mg. I still have problems even with meds but no where near as bad the adhd it causes sucks to. It's just a complete mess. Its just a complete total crazy and unbelievable mess of a disorder. Its just so mindfkkng especially without meds. Lord god I am thankful for the meds . Everyday life is a struggle but you know what . I am and think of myself to see it as still a huge blessing to have compared to how messed up a disease or disorder I coudl have bc I'm still able to have my mind with it just on a diff. Level than the norm. Same with my bone disease and back and leg problems. Regardless of everythig messed up , I am still able to be physically able just not as well as most and not as pain free, but I still can do everything i want to within limit so still a huge great big deal to me that yeah I like many others do have something disabling going on with us but we all need to stop and remind yourself of how much we could not have or have wrong . I have no pitty for myself either btw. .. hope I didnt bore anyone too much and if you think I wrote to much and want to be an as* well then look who's truly doing too much , if you take the time to whine or make a lame "funny" when looks like you would be the one who outdid themself. 😁 just count your places everyone .. actually don't count them. Just appreciate them and keep it going 😊
What?... I am watching a video in which a man is falling asleep while driving, it is 2 a.m. here and I got a notification on the science of sleep... I think the universe is telling me to go to sleep... Lmao.
jo andy bro get off youtube if you’re driving, u idiot.
Seeing hank look like he just woke up n just took a bath talking about sleeping science
I've had sleep paralysis with hallucinations several times before. It is extremely scary 😟
what did he look like?
Anyone else sleep so deep that you can wake up walk around, converse with people, go back to sleep and not even know it happened? No? Ok than just me...
I have been watching tv before bed for 30yrs. If I do not I can not fall asleep to much anxiety. In fact if the tv shuts off it wakes me up
Holy sh*t! A sciShow 25 min video? YES!
I’m going to listen to this as I fall asleep, Goodnight everyone.
I've literally felt asleep while watching, then woke up 2 min later, then restarted it FOUR TIMES. there is something wrong with this video 🤣
Are you here because you can't sleep? Me too. So I'll share some quick facts I've learned from reading way too many studies about sleep while I can't sleep:
1. Since this video, we've discovered why we sleep. It's so your brain can clean itself out. Google "glymphatic system".
2. Temperature may be more important than sunlight (or lack thereof) on your ability to sleep. Your body temperature needs to drop a few degrees to initiate sleep. Try taking a hot bath or a long hot shower 2 hours before bed to jumpstart your body's cooling process. Google "body temperature sleep".
3. Being bored for an hour before bed can help you get sleepy.
4. I need sleep, so I can't think of anything else. Do you believe that thing about caffeine at 13:20 or do you think that people who don't sleep enough are going to be more reliant on caffeine during the day because they can't sleep? I mean, I get that you shouldn't have it in the few hours before bed. I'll even grant you after lunch. But 12 hours? Maybe if you're the kind of person who takes a Benadryl and is out for 2 days.
5. Go to bed.
Your videos feel like playing at 2x
I've only experienced sleep paralysis a couple of times, and it's terrifying, you're awake but can't move and I saw a shadowy figure leaning over me and pressing on my chest
Thank you for this video. I have Asperger's and associated genetic insomnia, so I'm always looking for a better understanding of the complicated processes involved with sleep, or lack of it.
13:53 oh this happens to me a lot. I think I just closed my eyes and slumped my head for a second, only to wake up and be told I was out for half an hour
I got the whole LEGO movie as an ad lmao
While doing today’s crossword puzzle the clue “Sleep disorder “ popped up 😂
I'll grab a coffee to stay up for watching this.
I was an only child up until the age of 8. When my sister was a bit older than a baby (I think she already started walking), my parents put her bed in what was my room. I started sleepwalking. Loooking back, I think it was stress, but I never resolved it. I started to sleep a lot better when I got my own room again (when I was 12 or so).
One time i had sleep paralysis. I fell asleep watching youtube and i opened my eyes but couldnt move. And a huge "spider" crawled towards my face. I closed my eyes again and was able to move. Ripped my bed apart looking for said "spider" until i realized i had just experienced sleep paralysis for the first time.
