Hey guys! How many hours of sleep do you need? Btw, these nighttime habits make you fat kzfaq.info/get/bejne/ptiCn8tjr8ipno0.html

I did this once for 4 years they call it college i hear

I too did this *experiment* once, it lasted about 30 seconds then I went back to sleep.

Me watching at 3 in the morning knowing I have to wake up at 7 am 💀

Me at 2 am on google :- *How to sleep 8hrs in 4 hrs?*

The only reason I want more hours per day is to sleep longer

I can't take naps... When I try I just end up sleeping 5 hours instead of 30 minutes

me when i try to nap for 30-45 minutes : * wake up 3 hours later*

I'm already used to it with 4-5hours sleep in daily basis.... 4.30am -wakeup 6.00am -work (12hours) 7.00pm -back to home 8.00pm - etc 12.00pm -sleep Since I'm a part time student still need to work on with assignments/projects in routine from 8-12pm And i still don't enough time to workout in gym...

Brought to you by every corporation who would love you at work ALL THE TIME

I, with unbreakable passion, hate the music in these types of videos.

When you don’t do it by choice, you just have a lot of work...

I've now done this twice, once was called college, now it's called parenting!

computer addicts already mastered this

6 hours sleep at night and 3 hours after school, that's how it's done.

Everything you said is absolutely true. I actually sleep 4 hours a night and have more energy and am more productive and alert than compared to a full 8 hour sleep. I also get a 20 min nap during the day and wake before the alarm goes on...... Amazing

Am I the only one here who slept at 12 and woke up at 4 and then trying to know that this much sleep is sufficient or not😂

I've been trying my own experiment for the last 14 years, sleeping 12-14 hours a day.

This video made me really want a good 8 hours of sleep

Modi's photo is also there with all great minds 😂

I've been doing this since my early twenties. Every time I hear someone go "I wish there were more hours in the day" and I try to explain there are generally enough hours, I often end up getting some variation of "yea but that takes work"...

I went to sleep after watching this video

Expected photos every day with few main facts not a cartoon story full of redundant informations.

I get around 4 hours of sleep daily. Life of a college student.

For those have high blood pressure, depression and vestibular disorders like me...do not try this , if you want to live little longer. My systolic blood pressure jumped from 122 to 137 just one night lacks of 3-4 hours sleeping.

I work at the sleep laboratory and I consider this dangerous to put it mildly. First, sleep occurs in cycles with duration about 90-120 minutes, where all the sleep stages are (should be) present: NREM 1 - NREM 2 - NREM3+4 - REM. In healthy sleep their proportion in consequent sleep cycles changes: NREM 3+4 are longest in first cycle and then they get shorter, and REM si longest in the last cycle. Both of these types of sleep have significant effects on health, not only REM sleep. Regulation of sleep is also very complex (see Borbély´s model of sleep regulation) because it depends on sleep pressure (i.e. time spent awake before) and circadian rhytmicity, where external and internal stimuli play role (like darkness inducing melatonin secretion). The two factors should be in synchronicity for onset of sleep. One can fall asleep without on of them, but the sleep is of poorer quality. While the video and comments mention that REM sleep will start sooner in naps, it does not mean that its duration will be sufficient. Also, there is no mention of NREM3-4 sleep that is equally important but for other purposes. This sleeping pattern disrupt normal distribution and possibly amount of healthy/physiological sleep phases. Moreover, both short and prolonged sleep deprivation have been proven to have severe health risks, not only in neurocognitive departement but also on cardiovascular. Just one hour less in sleep in spring time shift was shown to be linked with higher incidence of heart attack. And poor sleep quality with lack of NREM3-4 and REM sleep is one of the factors contributing to cardiovascular morbidity and mortality in patients with obstructive sleep apnea. The research of effect of poor sleep quality and sleep deprivation on health is overwhelming. And lastly, I think this is to prioritize social and working aspect of life (productivity, creativity) over indidual health. Even saying things like: ancestors did it such and such... isolated tribe does it like this.... overall REM sleep might be still sufficient ...... this and that person tried it and it feel great. It is remarkably like wishful thinking, like wanting to make excuses to your own body. "Sorry, my body, my heart and brain, that project is really important, and I so want to binge watch entire channel I just discovered on youtube, oh, and I always wanted to read that book. You won´t mind a bit less sleep, right? We´ll find some confirmation of its benefits online, I promise" It is not far above making your whims more important than your health and lying about it to oneself.

REM lasts "exactly 20 to 30 minutes"? I don't think the word "exactly" means what you think it means.

I realized if I got 8 hours or more I still wake up sleepy af if I sleep like 5 6 hours I'm more energetic

Take a cold shower after waking from a 4 hr sleep, after that you’ll feel good. Thank me later!

Magical... by sleeping only 4 hours a night, your clickbait pictures will completely disappear.

I try to sleep at least 24 hours a day I feel great all the time.

Brightside: Did by many genius... 0:56 *Showing modi's picture* Ok.... Enough internet for today.

"They dont like sleeping in general" *EXCUSE ME WHAT*

I've been involuntary sleeping like this for years, due to stress, and only falling asleep due to exhaustion. oftentimes I can't nap until I'm so tired that I crash. I'm not productive and struggle completing tasks all the time. Living like this feels, well, nothing good.

If I sleep 4 hours a day, will I turn into a cartoon character too?

As an insomniac , I find it hard to relate to how hard it was for this guy to sleep 4 hrs. I hated not sleeping when I was younger but I grew into it growing up . People complaining of lack of sleep always annoys me but I don’t say anything . Just how I am

I love that blur bit when it happens to me i have so much fun with it hehe its like looking through the window of a 'constructed life' for me

Between the anecdotal evidence, obnoxious music, preachy focus on productivity, and trite advice given at the end, this video has made me more mad than anything on KZfaq has in a while! A+!

i like to sleep 14 hr

One of the best videos I have ever watched on bright side

Been sleeping 2-4 hours a day with no naps for 2 years and I still feel energized throughout the day and I don’t have bags under my eyes or have skin problems 😊 When I have gotten 8 hours of sleep I feel like I wasted half my day .

Rule#1: Never listen to a guy who stylizes his cartoon self to look as hipster as possible.

STOP visiting KZfaq in order to be more productive!!

I’m on my second week of polyphasic sleep now. The only day that was difficult was day three. My schedule is 5 hours per 24 hour cycle. I feel slightly more energetic than prior, other than that, not much difference internally. I do get a lot more accomplished.

I love that. "Sleeping is for the weak" Now that's brave.

Don't give up on your dreams, GO BACK TO SLEEP.😊

I've slept for 15 hours before, it was wonderful😌

I sleep 5 hours every day and I wake up feeling healthy and energetic. Not all bodies are the same, see millions of people can’t follow my sleep schedule and millions can. We’re all different and as a plus, I have insomnia and I have my entire life. I’m one to not be bothered by it. It doesn’t disturb my day. I get the amount of sleep I want at night.

play it at 1.25% speed, thank me later

This guy really wants his pool.

Yeah I get it, but it's not scientific enough. How was your blood pressure, before and after? How was your testosterone level, before and after? Are you sure about the good LONG-term effects? Are you sure you are living a healthy life or you FEEL you're living healthy? These are two totally different things!

I sleep 12am - 5am Exercise- 20min My backlog studies- 5:30am-7:30am School - 8am-3pm (I usually bunk English & P.E. class cause I have to study the remaining part of the backlog studies 😌) 3pm-4pm - Nap (yaa i call it nap 😅 I take it while going to tution in the car) 4 pm - 7pm - tution classes (for my important exam) 7 pm - 8pm - Nap/ stress relief meditation (again 😂 in car) I'm not a meditation lover okkaaayyy 😚 8 pm - 12am - Revision of what I have learned in tution 🤧) It's okay for me btw I sleep 7 hours in total 😚😚😚😚

I sleep only 2 hours in 24 hours. I do workout minimum 3 hours a day. I feel active and my brain is awake all the time. Its been 3 years as if now I have no health issues.

This guy looks a bit sketchy to me, I'm not sure if I can trust what he is saying.

I wake up to fall asleep. I love sleeping

I need 4,5 hours for sleeping daily. That's enough to me.

I’ve been practicing this without even knowing this was a thing, I just looked up if it was ok for me to sleep less. I’ve been working to jobs so this makes me feel much better. Great video

this is the dark side of bright side...

Maybe by working on overcoming your tendencies for procrastination, you could improve your productivity by developing time management skills?

Extremely useful especially that extra tips at end!!!!!

This video is good. Thanks for sharing. Going to start my schudule.

This video has the same feel of an anti-depressant commercial. Life is not meant to be a giant to-do list. Think I’ll pass.

The body can adapt to anything, it goes into survival mode but doest mean that 4 hours is healthy. Just saying

Each individuals biochemistry is different. If it works, great. If not, great. It's all subjective.

This is Today's most valuable video for me😇

Can we talk about the fact that of anyone tries this that person becomes a public danger if they drive to work ?

naturally mastered this during final weeks

I am going to try it now on... no matter, what does it take... i just wanna complete my to-do list and achieve my goals ✊🏻😃❤

This is a temporary solution, I've been doing this because of work (not through choice), after a few months it's a deterioration of your health, and after years it's like being a severely deteriorated version of yourself, you'll burn yourself out

I accidentally did this while away at college. Sleeping a few hours a night. Nap after class, and after tennis practice. I just remember ALWAYS feeling tired.

Here I am stuck in the KZfaq marathon again

Coming here to try this because lockdown is the perfect time to try a new sleep pattern

Eversince i was 17 years old i have been doing this kind of thing ,and when i grew older i was super used to this kind of sleeps, and it gives me more time to do things that i have never done.

Your voice makes me want take a nap.

ever have a kid? boom polyphasic sleep schedule.

Great video …never heard of this sleep pattern

I've been running on 4 hours of sleep a day for 3 months now. Gotta love insomnia when it pops out of nowhere.

This video would have been better if the guy who did it was just talking about it normally

Sleep researcher here. There is no research supporting this at all (if you find any, I would be delighted to see it). There is a lot of research supporting the destructive effects of not sleeping enough, though. Use at your own risk.

I obviously want to do it. thank you so much for sharing the knowledge.thank u very much😍

Going to try from tomorrow.. Will keep you updated 🙂

I did this for 2 years while working graveyard and going to school. Its not worth it, to do it just for the sake of doing it. You gain weight (I was going to boxing classes at the time too) if you're not extremely careful. You become cranky and angry with everyone. I personally began feeling chest pain and started to lose my hair. I feel like I aged rapidly compared to my peers. I switched to afternoon shift last year and its the best decision I ever made. I sleep at least 6 hours every night now and I feel like a brand new person. Experiments are cool, but sleep is better.

I used to sleep like that but as soon as you start sleeping 8 hours a day, you'll find out that there really is a big difference, I mean for sure you can stay alive and do your work with 4 hours of sleep but the quality is not comparable

What software you use to make the illustration video?

i have to be up in 4 hours so i looked up 4 hours of sleep on youtube

i didn't know robots sleep

I've slept 5 hours every night for a couple months... I don't really think it's a good thing though..

This is one of the best Bright Side's video in my opinion

*this made me so sleepy*

1. Turn off your phone. *Warning: This is only for professionals. Please do not try this at home* EDIT: Comment Update Patch: Fixed the "warning" word not highlighted as a warning sign.

I read this as I Decided to Sleep for 4 Days and was pretty disappointed to realize my error.

Did anyone notice Modi in the frame ? Great man indeed.

Excellent video!

This is not how REM sleep works and the entire video does not have any scientific backup. The only good advice this video gives is: "DO MORE RESEARCH". And also, please don't change your life in order to "get more productive at work"... you don't live in order to go to work...

I swear the brightsides a robot this dude never talks like a normal person in all his videos

Ok it sounds great but, school going teens or children especially those in 10th , 11th and 12th just can't follow it I mean when they will take the naps , as they can't sleep during their tutions and classes because these are the career making classes. Plz tell me.

I have been running on 2-4 hrs sleep for the past 2 years. No naps. But I do feel like everything is 2D

Wish there had been actual scientific research linked with this video

This doesn't work if you need to do ANY kind of physical activity more than just sitting in a chair all day. I sometimes find myself awake for 36 hours at a time if I have a bit too much coffee or if I stay awake past the time I would normally go to sleep and then I become less sleepy again. But I always have to pay for it afterward with a 12 hour sleep or so to catch up.

This is the most useful video of Bright Side !
