I Decided to Sleep for 4 Hours a Day, See What Happened

One of the Bright Side writers decided to adjust his daily routine to leave only 2-4 hours for sleep! Do you ever think about how cool it would be if there were more hours in a day?

You would easily have time for everything: work, hobbies, friends, and family or just lazing around doing nothing at all. But enough dreaming, let's get back to reality. The only way to make it happen is by sleeping less, but would that actually work without turning you into a tired grouch?

My thoughts after the experiment 9:48

SUMMARY
If your life is like one big to-do list that you just can't seem to keep up with, then polyphasic sleep is probably for you. All jokes aside, I definitely became more productive, and I have a lot of spare time that allows me to do everything I want and even more.
On the other hand, it can be difficult since the whole world is on a completely different regimen. Your friends and family might think it’s weird when you tell them you can't go out with them or ask them to pause a movie so you can take a nap. In any case, it's your choice to make. Just do your homework first, and then go for it!
If this sort of dramatic change isn’t for you, don't worry! There are still lots of things you can do to improve your productivity.

Hey guys! How many hours of sleep do you need?

[Wvdlinden]

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

[KastaRules]

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

[ratuintan]

[gpcaraudio]

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

[mohammedqureshi]

I went to sleep after watching this video

[socialgenerationyt]

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

[thiwanjwilliam]

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...

[solaireofastora]

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

[kennethshiro]

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

STOP visiting YouTube in order to be more productive!!

[sharlzm]

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 Amazing

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

[ziraniko]

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.

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