"I don't think he knows about second bedtime, Pip...."
I retired in 2012. After I was able to fall into a natural rythym, I started going to bed around 10pm and wake up at 2am. I'd get up and goof around till 4am and fall back asleep till 8am. It was great. Then went back to work part time and still was able to keep the pattern. Super refreshing.
Im the same i love those quiet hours alone
I'm retired and I do this too! I'm more like 11pm~4am. Wake-up time varies. When I'm up at 3, 4 or 5, I straighten up the kitchen and make coffee, then putter around on the internet and go back to sleep. Then have a real breakfast.
I work full time and do this. I always thought it was the norm: sleep 4 hours, wake, do nothing important, then sleep a little more before I actually have to get up and ready to be moderately late for work.
@@z_ed so I'm not crazy
@@dmo848 nope, in fact you're normal, it's the sound sleepers who are abnormal. I have slept a full 8 hours before, but that was when I had a cold or was completely exhausted and sleep deprived from earlier.
I believe the biggest thing that ended biphasic sleep for most people was having to work in factories and offices, where you must be alert on somebody else' schedule. They want you there for eight hours every day, and we have to do everything else, including commute back and forth, on our own time. Consequently, most people are chronically over tired. This sleep abuse begins with the public schools, compelling students to be up, out and alert for long hours, and catch their sleep as best they can.
I don't think biphasic sleep appears to make anyone any less alert during the day, 8 hours is still 8 hours?
@bushlovesska she's saying you can't do biphasic sleep while being required to work or go to school 8-13 hours a day. You could do one short phase of sleep, but by the time you were ready to have your second phase it would almost be time to get up for work, so you would be losing half your sleep. This requires us to cram all of our sleep into one longer phase so we hopefully don't fall asleep at work
So we can be productive little workers for society to get the crumbs of money based on the amount of work done. 😂
"Over tired"? *Overworked* - that's the word.
Fuck factories fuck being somebody else's wage slave. And fuck trading your life for work that isn't bringing and benefitting society together in advancing our empathic and telepathic evolution to a place where we can live as one in harmony with the planet and communicate with terrestrial and extraterrestrial intelligence as a means to expand our knowledge of the universe. As long as this labor evil at the expense of our spirits and consciousness exists. The biphasic sleep cycle will be something of an aberrition for most. And, we will suffer as a species because of it.
Since this video came out, I have tested many methods of sleep, and found my favorite is three seven-hour sleep cycles, interspersed with three food breaks.

i feel called out
okay listen theres no need to call me out like that
It hits tho
That explains why I am usually very tired at like 9-11pm, but usually after forcing myself to stay awake, I then hit a time where I am super awake and focussed until like 2-4am. I often felt like that's my most productive time of the day.
I guess that sudden rush of being awake and focussed again is my body assuming we just skipped first sleep and getting into the "awake in-between" mode. So I've been denying myself half the sleep I need, for decades. Ouch

I think if you dont sleep when you get tired you get a cortisol spike that gives you the energy. Might be wrong, cant remember where i heard that.
Its an issue with elevated cortisol, fix that and you can sleep 8 hours without fail
I was stationed on the island of Crete for 13 years. Many of the shops, on a couple workdays, would shut down around noon. The folks would go home, eat lunch, take a nap and then go back to work for 4 hours.
That's a siesta in Latin America. Typically people woukd take a nap inside during the hottest part of the day
This makes perfect sense to me honestly. Any and every person I’ve ever known enjoys an early afternoon nap.
Used to be standard across Mediterranean countries: might still be?
avoid hot, and HUMID sucks the energy out of you. even in Canada grandpa would nap in the noontime, but a breeze would come up around 4p.m. and we'd get the hay picked up and stacked and other jobs also, dinner would be light. so you didn't gain weight.

I didn’t realize I did this without knowing. As a college student I’d always take a nap right when I got home sleep for like 4 hours stay awake until a little after midnight and then fall asleep again. It actually feels refreshing, you never feel groggy
My freshman year of college, I didn't have a job for most of the school year, so I would take a nap from roughly 3:30-5 PM each day, go to supper, get to bed late, and sleep about 6-7 hours from midnight on. In hindsight, I think that was the best sleep schedule I ever had and don't really recall being tired very much. Not quite the same as what you stated, but maybe in the ballpark. The next year on I had afternoon obligations or jobs so it never happened again, and then real life working world, of course not.
Yep this is how I've been for years now! It somehow feels like I've got more hours in the day bc I have more energy to do things!
Lol I did this in high school I ended up getting diagnosis with season depression for sleeping too much xD I'd go to sleep around 5 wake up around 10 go back to sleep around 2 and wake up around 6am
@@DugrozReports That is the exact same sleep schedule I use. I feel way better sleeping for 6 hours at night and 2 hours in the late afternoon and trying to sleep 8 hours in 1 go.
I also used to do this in high school, not on purpose but just because I was sooo tired! I always thought it was my boring homework that was actually putting me to sleep tho 🤣🤣
Having retired about 10 years ago & living alone, this is exactly how I sleep, so it's interesting to hear that I'm just doing what comes naturally. Except that I generally fall asleep on the couch watching RUclips videos---no seriously, that's exactly what happens, doesn't matter how interesting they are, I just conk out, wake up, do stuff, go to bed. Works for me!

Sleeping when you feel like sleeping is one of the greatest luxuries we can get.
A/C has a HUGE impact on siesta practice. I frankly grew up equating siestas with laziness...until I moved to a region that has hot summers and didn't have A/C. We got up before dawn, worked to 11am or 100F - whichever came first - then knocked off to read, nap, etc until 5p, at which time we got back to work. If it was a big project we'd put up lights and work until after midnight. I have since moved away, but my folks still follow this pattern (though they do now enjoy having A/C).
A/C best invention #2. #1 is fire.
I used to sleep like this during high school. I was always exhausted when I got home so I usually slept 3-5 hours, woke up and ate, did homework, had free time, and went back to sleep before waking up at 0600. It was very natural to me but mom didn't like it
honestly parents and grandparents judging people for sleeping at certain times.. i just cant. i love my grandpa but to him if i wake up at 9 or 10am he always has to make some comment about it. I'm like, grandpa... yeah I woke up at 9am but I stayed up doing homework and studying until midnight. I slept the same number of hours as you, but just different ones.

I’ve been doing this all my life, I thought my sleep patterns were wrong, or I was abnormal we’re always told you need eight hours of interrupted sleep, I didn’t know this was normal. I sleep four hours wake up, read, watch tv etc then go back to sleep. I’m no longer going to stress about getting eight uninterrupted hours of sleep
same
It's almost like we're being 'trained' to 'think' a pattern unnatural for us, but super beneficial to companies, is the correct way.
During Covid, for about a year, I definitely fell into this pattern, plus a “siesta”. I’d wake up at sunrise every morning, nap for about 2 hours in the early afternoon, be awake until a couple hours after sunset. Wake up around 2AM, go back to sleep about an hour or two later, then wake back up at sunrise. It also resulted in getting less sleep during summer than winter.
When I stopped paying attention to clocks and worrying about the time, I got some of the most restful sleep of my life.
Covid lockdown was the only time in my adult life I've felt healthy and happy on a repeating, regular pattern, day after day.
@@TherronKeenFully agree! I still wish I could replicate that routine I had. Best days of my life.
I believe it. Time was standardized for the Industrial Revolution. They needed to time the trains.
@@TherronKeen I thought it was going to bring forth an era where you work from home, and your schedule doesn’t really matter as long as you make it to meetings on time, and your work gets done…
But nope. Back to the office for me.
@@jacksont9455its all because of the office real estate. Its really upsetting that we’re being forced to go to an office when we don’t need to.
Jokes on you, I do sleep in two phases: first when I fall in front of the TV or laptop after dinner, and second when I realised that my back hurts from falling asleep on the couch, so I move to the bed in the bedroom.
My mother does that most nights as well. When she wakes up on the couch she goes to the bathroom, brushes her teeth, removes her make-up etc. and after that finally to her bed. It seems to work well for her and I'm guessing it's not too far off from the two 4 hour long sleep phases etc.
Try and throw in an extra hour or 2 in between and see what happens
1:46 😭 had a sad but hardy laugh at that one.
I actually used to do this for several months when I did a ski season and worked night shifts until 7am. 4 hours sleep in the morning, skiing during the day and then another 4 hours sleep in the evening. It felt oddly natural once I got into the swing of it!
Or did you feel good because skiing and working exhausted you so much that you fell asleep really easy and slept for the complete time?
Well good for you 😌
@@Jehty21 that was it for me, the only time I've consistantly napped in my life was during my ski season.

Interesting
Heard about “punctuated sleep” a few years ago, and the old pattern of having a wakeful break when folk did ‘everyday’ stuff before returning to bed. Stopped worrying about waking up during the night. Writing this at 04:30. 😊
For the last 8 months I’ve been without work and study while I recover from a major medical condition. And so, I don’t have a schedule to follow and have let my natural circadian rhythm take over.
Without fail I wake up during the night roughly 4 hours after falling asleep, get up for an hour and write or read, then go back to sleep until I naturally wake up again roughly 4 hours later.
I’ve been really stressed over this, thinking something is wrong and I’m losing precious hours of sleep but I’m beginning to understand that’s not the case. I actually feel great. I’ve started lucid dreaming, recalling all my dreams, waking up energised, don’t feel the need to sleep in.
I never use to be a morning person. I dreaded waking to the 5 separate alarms I needed to wake up. Now I’m awake and out of bed at 5am-6am. I work out in the morning and I don’t feel the need to eat or snack until 1pm-2pm.
That’s just my personal experience. Before I found this sleep schedule i had severe sleep problems. I needed incredibly strong addicting sleep medication. I was falling asleep at work, standing up in the shower, at the wheel of my CAR!!
I don’t think this way of sleeping cured all those problems, it was a combination effort of other factors but it definitely contributed greatly.
Siesta is traditional in Japan too, for Japanese farmers especially the hottest hours during summer, you couldn't farm anyway, people just took naps during that time.
I did that when I was working in the Western Australian desert for a few months but if you don't have an air conditioning unit or an underground cellar to sleep in then things become difficult. It would reach temperatures over 50 degrees Celsius in the house unless you left the aircon running. For anyone who never experienced that, at that temperature a block of cheese will melt like butter, the water left in the shower pipe will come out so hot it burns you and even if you are young and fit you feel like you are going to have a heart attack while doing nothing.
Our aircon was a bit weak so during the day the temperature in the house would still reach nearly outside temperature which is why we later switched to do our shopping during mid day, at least the car and the shopping center would be cool.
@@blafoon93 that's harsh... my home town which is a semitropical region never went over 39 degrees since record, and 39 is already deadly.
that's why the Indian subcontinent has them too - especially during the summers when daytime temperature and humidity exceed 35C & 80%
@@12kenbutsuri 39°C is not necessarily deadly - it depends on air humidity.
But it is certainly a dangerous temperature.
@@sertaki true, in a desert it isn't that bad. Tokyo area gets quite humid though.
I remember when I first learned about this in highschool, stopped worrying about not sleeping enough. When I would wake up at 2 or whatever I wouldn't try to sleep again, I would read, study, maybe shower (if I could get away with it), light workout, whatever. Felt oddly nice being awake when it's quiet and dark, and I felt way more focused than during the day.
Well you clearly didn't learn shit. This isn't advocating less sleep, its the same amount of sleep split over 2 periods in the day.
@@fenixchief7 Well you clearly have shit reading comprehension. She never said she got more sleep
That all sounds great!
I should try that, as I only sleep 4 hours per night.
That sounds like the same result as the people who wake up at 4 am to work out, read, morning activities, and they’d go to work at 8 am. I think we were always meant for physical activity and care before long hours of staying up.
going to bed and sleep for 7-8 hours at once feels like an eternity and it's kind of depressing thinking that you lay down for that long just to get some rest, so this makes perfect sense to me, it feels like i'm never sleeping, and can go pursue my goals with no breaks
It's literally the same amount of sleep in a day lol
I'm so happy to have heard this!This is my pattern. I've wasted too much time trying to get that 8 hours! Sleep hygiene, meditation, essential oils.... Left to myself, I sleep in 2 phases at night and have a midday siesta. And that is how I feel best. Now that I'm semiretired and work from home, triphadic sleep for me!

@@TheFlyfly If you have a job that's taxing on your body, that would have an effect. It's also possible you could have Sleep Apnea or something else that is keeping you from feeling refreshed. I would sincerely see a doctor if you have health insurance coverage.
Consider, at the equator, there is a split of 12 hours of light/12 hours of darkness year-round. At the middle latitudes, both north and south, we see the same 12/12 split at the equinoxes, with the extremes of ~9 hours of daylight to ~ 15 hours of darkness at the winter solstice, and the reverse of ~9 hours of night and ~15 hours of daylight at the summer solstice.
Our nights are *always* longer than 8 hours (unless it's summer and close to one of earth's poles). If we only need 8 hours of sleep, and we have 9-15 hours of darkness, then it makes sense that humans without artificial light sources would sleep at the beginning and the end of the night, and do something indoors/at home in the darkness in between.
This actually happens to me a lot so I’m glad that there’s a historical record of this being normal.
Polyphasic sleep is fascinating. I’ve actually dabbled in that sort of thing in the past, but alas it’s kind of hard to work around how the rest of society works, so there are always issues actually planning that in and on the other hand you’ve hours you’re awake with nothing you can really do.
Surely with the way things changed last year, it is now more feasible... As for what to do, I think the same things mentioned in the video would still work.
I've definitely accidentally fallen into some biphasic sleep in the past where I played video games in the middle, maybe I should try doing it on purpose
@@Hugobros3 There are a limited number of jobs that would allow for abnormal schedules, basically just software engineer, writer, and designers / other artists. Assuming they don't have meetings during the day which they most certainly do. You might say it's "possible" but for only a fraction of the population.
Nice profile pic
@@michaelkelly7379 I sleep 8 hours a day. so if i interrupt that for two hours wake time it would be 10 hours. That leaves 12 hours for the rest of my day. Since i don't work that much and mostly for 3-5 hours a day it would be no problem to use this sleep pattern. even if i would work full time, which is about 8-9 hours where i live (of course there are people who work more) i would have enough "time" to do interrupted sleeping. it is just a thing of prioritizing. but honestly i think our bodies don't car. as long as you have enough sleep. maybe you only sleep 98% as good, when you do it in one session. to comensate you just sleep 5 minutes more. problem solved.
This concept explained something to me, that has had me stumped for a long time, namely monastic schedules. Most monastic orders in the middle ages had a mass planned for like 2 am every night. I wondered for a long time if that was some kind of "mortification of the flesh"-thing, having to wake up in the middle of the night to sit through a mass. But no, people were awake at the time because that's how sleep schedules worked, and there isn't much else to do in the pitch dark... it makes perfect sense.

I was diagnosed with Chronic Fatigue Syndrome about four years ago. I have been forced to just let myself sleep as much as my body wants, which is typically 11-14 hours per day. Upon not setting any alarms and not having to wake up for any commitments, I’ve fallen into a biphasic sleep pattern. I generally fall asleep at about 2:00-3:00am, and I awaken at about 7:00-8:00am. I’m awake for about two to three hours, then I fall asleep again until about 5:00-6:00pm. It can vary a bit from day to day, but I pretty consistently wake up for a couple of hours in the middle of my sleep time. Those hours are productive, too, but I fatigue quickly after a couple of hours and have to go back to sleep. I’m able to have about eight hours of decent "awake time" after sleeping like that.
That’s how it works for me if I’m not doing anything, at least. Sleep, wake, do a few chores, sleep, wake, make food, watch, TV, then bedtime again. Not much of a life. If I actually DO something, like work (I work in opera, but I only work about six weeks per year, broken up into three separate two-week segments), I’ll wake up, go to work at 5:00pm, work until 11:00pm, come home, fall asleep by midnight, and sleep until I have to wake up to get ready to go back to work. Even a trip to the grocery store causes me to sleep 14-16 hours the next day with no awake time in the middle. So I don’t know how this sleep pattern works in normal people…
I recommend trying this, which might seem ridiculous, but might just work: try eating an unbelievably large amount of food
I was at some point in my life living somehwere where the plate of food was 3-4x the amount that I was used to eating, but I gradually began to eat that much, and then I have now so much more just, life inside of me, you know? Try it out, especiaslly if you're thin
@@MiauFrito unfortunately, I’m not thin, so eating a large amount of food isn’t a good option.

I actually did try biphasic sleep for three weeks during my uni holidays in wintertime and it was definitely something. I felt like I had twice the amount of time to do things. I slept the first 3.5 hours after sundown and another 3.5 hours to wake up after sunrise. Would recommend if you have the time and flexibility to do so

You cant say that modern light bulbs changed our “natural sleep patterns” when studies of pre-industrial societies and tribes (excellent models of pre-industrial human society) exibit exclusively monophasic sleep patterns. These tribes existed far before the advent of even oil lanterns and candles, so the argument that going from candles to electric lightbulbs somehow changed our sleep patterns so drastically does not hold up.
This is fascinating! I'm narcoleptic, which means it's almost impossible for my brain to enter the deep stages of REM sleep without taking a medication. However, currently the medication won't last for eight hours, so I have to wake up after four hours to take a second dosage. Granted, I'm not usually awake for more than fifteen minutes then, but I'm surprised that my sleep schedule is akin to what our ancestors did.
Sounds like the right medication.

Traditional Spanish schedules include interrupted sleep. Even today it is common for people most spaniards to wake up after their post-dinner "nap" then go back to sleep; I feel like distinction of the extra day time sleep period is more unique to Spanish siestas - this would imply a difference between multi-phasic sleep and bi-phasic sleep (Spanish style being multi-phasic).

I've been trying to do biphasic sleep, but I find it takes me about 4 hours after my first sleep to feel tired again. So after the next 4 hours, I've essentially cut my day down by 12 hours.

If I get up to do something during that 4 hour period, I have to turn on the lights or im probably looking at my phone, which probably contributes to why it takes so long to get tired enough for my second sleep.
Try reading. Reading makes me sleepy
I'd just do some torba training. Night vision is typically enough to shoot between sleeps.
try blue-light blocking light bulbs, check out Dr Jack Kruse
I just woke up from about 4 hours of sleep and then this was recommended.
with average REM cycles lasting 90 minutes, ever notice when you wake up without an alarm it's almost always a 90 minute interval from when you fell asleep. i.e., 1.5 hours, 3, 4.5, 6, 7.5, 9, etc? I find a 4.5 hour rest followed by a 3 hour nap (7.5 total) to be the optimum amount with best result. Less I feel sluggish, more I feel sluggish.
Am I weird for sleeping 12 hours at once? Even with an alarm if I feel no pressure to get up I’ll stay asleep for ~10-12 hours. Or.. Maybe it’s just to make up for the fact that I hardly ever sleep during weekdays.
@@kyleafythelegendaryleafeon7404 sleep battery is real. I used to do that too when I worked 12 hour shifts I'd sleep 4 on my work days and 12 hours on my days off
thinking about this tripped me out its so weird how everything in our brains comes in waves like that
Totally agree! I do 3 sleep cycles 11pm to 3am, then 2 hours watching youtube, then 2 sleep cycles 5am to 8am. Shower and breakfast and go to work at 9am.
Almost always lol, if nothing else wakes me up it’s 95% of the time on those 90 minute intervals, it’s pretty cool

In pre-contact Hawai’i, people would take a nap in the middle of the day to avoid the sun when the UV radiation was strongest. Basically a siesta
This has blown my mind. I thought I was abnormal, because if I sleep by 10 pm I'd always wake up by 2 and stress about not sleeping through the night. Forced myself to start sleeping after 11 now. I'll try this intentionally and see how I feel.
Three hours and then one hour is more like it, maybe with a fifteen minute nap here and there. Keeping a schedule is more of why we have our current sleep patterns. Before the light bulb, people were sleeping 9 to ten hours. Sleeping patterns also changed throughout the seasons. In medieval Europe, people fell asleep when it got dark and the woke up in the middle of the night. Since several people usually slept in one big room, they would socialize for a few hours and then go back to sleep. In the middle east summers people woke up very early in the morning and then escaped the mid day heat by going inside and going to sleep. Europeans would generally stay up later in the summer

In my early 20's i started getting really sick anytime i drank a caffeinated beverage. After 2 ER visits where the drs had no idea what was causing the issue i dropped my diet to bread and water until i found the culprit. Now many years later i have hit a point where the way you describe having 2 periods of about 4 hours of sleep is just natural for me.
I have blue light blocker lights to lessen the harshness on my eyes and i honestly feel better rested most of the time than i did in highschool. Most people still ask how the heck i wake up every day and well, humans havent had this drug for that long. Youd be amazed what can come naturally when it has to.
Speaking of misinterpreting, that letter shaped like a “v” is actually a nu and pronounced with an “n” sound. Just in case you keep reading your copy of Homer in the original Greek.
thanks i’ll keep this in mind when i resume reading my copy of Homer in the original Greek
Actually we don't know for certain how ancient Greek were pronounced. You are using modern Greek which is not quite right.
Apart from being atrocious, I thought Sam’s pronunciation was pretty good
@@thess0414 uh we do know how ancient greek was pronounced through comparison and reconstructions. The n in words like synthesis or economics is from Greek ν borrowed into latin as an n.
We could also talk about how ancient Greek was pronounced different to modern Greek, but he should be embarrassed enough already.
I already do this normally, except instead of praying for 1 hour, I overthink about life and suffer existential dread
When I go to SCA events I slip into what I tell people is a 36 hour schedule where I ignore the status of the sun. The people that have been willing to try it find out that all I'm doing is a two part sleep cycle that has me awake for more of the evening and night party cycle, without missing out on classes or market time.
I figured this out as a teenager that had multiple doctors claim I have insomnia. I only have trouble sleeping if I'm stuck, unable to get two 'naps' a day for too long. Most doctors I've had refuse to accept that this might be a thing for at least some people.
I randomly, out of nowhere and unintentionally experienced this pattern of sleep, not a long time ago, and i hate it. I felt so confused, tired, and that window of wakefulness felt like wasted time, zero enjoyment. Thankfully it went aways as it came, it was almost a nightmare😂
But i do love daytime naps of 30-45 min. I find them so rewarding, and i don't sleep more than 6- 7h/ night. And i wake up without an alarm, which is awesome!
I have noticed that when I brake up my sleep I get very vivid dreams in the second sleep cycle.

This is such a relief. I've been stressing out so much over this
I somewhat experienced this last week on vacation. I kept waking up almost right in the middle of my sleep (about 4 am). And felt oddly awake. I used the bathroom and then went back to bed.
However, at home, I usually find that I sleep completely through the night usually for 7-8 hours straight, so I don't naturally get up at like 3am.
I can vouch for the fact that this is an easy pattern to adapt. When I was at uni in the 80s (pre internet) we needed to use the labs at night to get assignment work done. I got into the habit of coming home about 3 or 4 PM, showering, and going to bed. My flatmate would wake me when she had dinner ready about 7PM. I'd then go back to the campus and work till 2 or 3 even 4AM, come home, sleep till 8AM to start first class at 9AM so it seemed like I was fitting two small days into every one. Needed to, what with 30+hpw contact and so SO many assignments that I still, nearly forty years later occasionally have nightmares that wake me thinking I have forgotten to do one that is due today

If you don't mind me asking, how old are you? Also, how are you doing on the biphasic sleep cycle? I am really curious
@@xmunchyx I'll be 50 next month. And it's different but it's fine. Mostly, the key is going to bed early so that when my eyes slam open four or five hours later, going back to bed after my bathroom trip is a more feasible choice than staying up. If it's 1:00 AM, I'm less concerned about sneaking an extra three or four hours of sleep than if it's 3:45 AM because the latest I can stay in bed before it's time to shower and shave for my commute to work is 5:45 AM. Sometimes my brain decides to ignore my phone's alarms if it thinks my body could use more than two additional hours of sleep and I'll wake up too late to show up to work on time. Since I hate calling in late for work, I work within my body's parameters and I'm regularly on time.
Don't you mean your prostate?
Before I sit through the video, I just wanna say that I’ve heard animals like horses tend to sleep like that, usually in the wild, where they’re in small packs, as a means of organized patrol during the night

Makes sense. I typically wake up around 3am every morning. But I think this bicyclic sleeping pattern only occurs when we get older. As a kid and a teen I had no problem sleeping for 8+ hours. So age is a factor.
For anyone that hasn't tried it this is great for people who need focus on tasks that don't take a long period of attention.
The period you're awake between two 4 hour sleep cycles is almost a focus state where you can focus on anything with your full attention.
It also radically changes your mindset throughout the day, it feels a lot shorter and your patience is increased significantly.
This makes sense evolutionary as well, sleeping in 4 hour periods and waking for 2 hours means that you are vulnerable for a less stretch of time throughout the night to other apex predators. It’d be harder for say a Jaguar to surprise you if your sleep pattern isn’t a solid 8-10 hours every night. Rather it’s a broken up rotation of a few hour long periods.
Tending to fires as well I’d wager, and other things that would want maintenance through the night, although none honestly come to mind lol

Yep, i was laid off in 2022 (thanks to covid) and had several months of non-institutional life for the first time since the the summer before I entered high school decades ago. My sleep patterns changed, and it didn’t matter when I fell asleep. Sometimes i got five hours, sometimes i got 10 hours, and sometimes in between. Sometimes i woke at 6, sometimes at 9, sometimes in between (i was training for my next job and job searching but according to my own schedule). Sometimes i woke in the middle of the night, a fact that otherwise would’ve prompted either anxiety or benadryl/melatonin to push me back to sleep so that i’d be ready for work the next morning. I’m working now, but looking forward to retirement.
For years, once my son left home, I would sleep when I was tired. I worked alternate early/late nursing shifts (our poor bodies had no idea where they were in the day). Now retired and living in Spain ive continued to siesta. If I dont at least rest I get too tired to sleep easily at night. Im off to duvet land now. 😊
I wonder if sleep schedules were different on different latitudes since the sun would have a different pattern
Days would still have around the same amount of natural sunlight, on average, although these fluctuations would affect those in more polar latitudes more.
Exacly, and that's only from some written sources. "People were reading, writing..." yeah all human kind all over the world just waste candles and lamp oil to do stuff in the middle of the night. Most of them live in countrysides in central europe, that's enough to find out that's pure fantasy of some writers. Not even documented in biology. Biology says that animals like cows need service from 5-6AM to 9-10PM in summer.
And as medic i recomend search for hormone-distibiution cycle to get idea why so many people wake up after 4hours. In most cases it's just moment of inner "gear-change", not need to awake but easy to.
@@BoraCM as a person that move from Venezuela to Spain, and later France, I can say the day light patrons are very different. I arrived to Spain in summer and I couldn't get why people were so crazy about taking sun. Then winter hit and I got it. Is so different that sometimes I don't get something very obvious, like why there's not lights in a kid park (because In summer is not need if they want to play until late, but in winter nobody wants to get out). Is so different that in Venezuela and other countries in the area there's not such thing as "7 of the afternoon", and you will never see that expression use in tv, only in book written or translate in Spain, as in Venezuela 7pm is always "7 of night"
@@BoraCM I don't live in a very polar latitude but during winter the sun rises at 7:20AM and sets at 4:35PM leaving us with only 9 hours of daylight. During the summer the sun rises at 5:42AM and sets at 8:31PM leaving us with 15 hours of daylight so it would depend a lot on the time of year as well
2:22 There has never been more obscurely perfect footage than a knight scrolling on a smartphone for “…assuming the past couldn’t possibly be different from the present…”
This is both funny and informative, and has finally explained my own sleep pattern ~ i.e., it's given me a lightbulb moment! I will no longer worry about waking at 3 or 4 AM, and feeling too energized to go back to sleep for a while.
I don't remember where I first heard about this but it was a while ago.
Unfortunately jobs don't allow you to live like this (unless you're spending 10x more than necessary for housing to live very close to work) but when I was able to do the double sleep, it definitely feels much better.
5:21 - that was a beautiful non-transition transition.
I remember camping alone for 3-4 nights in the middle of the bush, (not a camp site) and falling into this type sleep pattern nearly immediately as there was only a small torch for light and not much else to do at night other than sleep
Back around 1990 I was on a flight from Toronto to Vancouver. During the flight there was a piece by David Suzuki (used to host the CBC show The Nature of Things, a science TV show) where he brought up the fact this same fact: that we shouldn't be sleeping all at once but it should be split in two. Though sadly I don't remember much more from the flight apart from (a) that bit (b) the in-flight movie was Pretty Woman and (c) I didn't like the take-off or landing but was ok once the plane was level.
I think the biggest problem ends up being when you have jobs where you're on site for 12 hours a day, and then you have to take time to get to your job and get home.. there's not really enough time left to eat and sleep in between properly. So getting sleep all at once kind of gets forced on them.
Thank you, it`s a very great job 😻

They did a study on this years ago. The study put a group of people in an environmental where they had no light cues or time cues, just perpetual twilight. After about two weeks, the group fell into a cycle of two, four hour sleep cycles per 24 hours.
