Hey /his/, I have some broad questions regarding the sleeping patterns of people in the past.
1. Did people wake up at sunrise and sleep at sunset or did they sleep a solid 8 hours a day? Did this continue even when days were especially short around Winter?
2. How did people in the past wake up, alarm clocks were not invented. Dogs? Other animals? (Roosters I can imagine would be plausible).
3. Did the invention of artificial light for mass use such as the light-bulb drastically change human sleeping patterns since its creation?
Thanks for reading, I hope for some interesting answers.
>i know the french aristocracy slept from about 2am to 11am
This goes as well for anyone else reading, any knowledge you have of sleeping patterns within other cultures throughout history please share!
>The circadian clock, or circadian oscillator, in most living things makes it possible for organisms to coordinate their biology and behavior with daily environmental changes in the day-night cycle. The term circadian derives from the Latin circa (about) diem (a day), since when taken away from external cues (such as the day-night cycle), they do not run to exactly 24 hours. Clocks in humans in a lab in constant low light, for example, will average about 24.2 hours per day, rather than 24 hours exactly. Hence the term circadian.
>The normal body clock oscillates with a period of exactly 24 hours when it receives daily corrective signals from the environment, primarily daylight and darkness. Circadian clocks are the central mechanisms that drive circadian rhythms. They consist of three major components:
>A central biochemical oscillator with a period of about 24 hours that keeps time
>A series of input pathways to this central oscillator to allow entrainment of the clock
>A series of output pathways tied to distinct phases of the oscillator that regulate overt rhythms in biochemistry, physiology, and behavior throughout an organism.
>The clock is reset as an organism senses environmental time cues of which the primary one is light. Circadian oscillators are ubiquitous in tissues of the body where they are synchronized by both endogenous and external signals to regulate transcriptional activity throughout the day in a tissue-specific manner. The circadian clock is intertwined with most cellular metabolic processes and it is affected by organism aging. The basic molecular mechanisms of the biological clock have been defined in vertebrate species, Drosophila melanogaster, plants, fungi, bacteria, and presumably also in Archaea.
I think if you are in agriculture you have to sleep the same rhythm as your livestock, even in the modern era. You gotta milk the cow when it needs milking, you can't turn over and snooze for an hour.
Back in Pre-Colonial, Semi-Agrarian Philippines cunts slept at around 7:00 PM. Had to wake up at around 3:00 AM to work the fields when the Tropical Sun wasn't mind numbingly hot yet
Also its still dark for fishing. You could bring up a torch and attract fishies.
I can't recall the source, but i read somewhere that it was relatively common before electricity for people to have a "first sleep" ..wake up and tend the fireplace. Ten have a " second sleep" . At least this was the case in England
3) (if they were in one) Kingdom
4) Ethno-linguistic Group.
In that order.
A lot of tribes from North to South were Muslim. Animists became bitches of them.
Its just that Spain united the Animists, converted the to Catholicism, and used these people to beat up the Northern Muslims.
Meanwhile Southern Muslims had all sorts of allies to call from Borneo to Indonesia to help it out. Brunei defeated Spain in a naval battle in 1590's IIRC.
Not to mention Japanese and Chinese entities kept threatening late 1500's and 1600's Spanish Philippines, leading them to pulling back almost regularly their forces from the South.
I'm just sayin' that it's awfully odd that we would have evolved with a sleep cycle inconsistent with our supposed home world, but consistent with that of another planet at the same time as the first evidence of modern homo sapiens appears here. A planet that is believed to have been Earth-like at some point in the past, but has since ceased to be capable of supporting life.
Or, you know, WE WUZ MARTIANS.
1st and second sleep. People would have a meal at sunset, then sleep. That is the 1st sleep. Wake up in the middle of the night, this is why so much shit happens at midnight in the literature. Then go back to sleep for the second sleep.
The industrial work day killed 1st and second sleep.
There are many sources for this, so you can google it.
Try actually going to sleep at sunset. You will most likely wake up and be awake for a while before you can get back to sleep. I did it last night. It was weird waking up in the morning and not feeling tired. I imagine this is how our ancestors must have felt.
They did a study recently where the temperature plays a large role in the times you wake up and go to sleep, it was a study on an amazon tribe I think, apparently at the coldest point of the morning your body naturally responds to get up.
Actually it's the sign of change. If temperature is decreasing, it's a sign night is upon us. If the temperature stabilizes and begins to increase, its a sign day has come. But if you use climate control, your body can't figure out shit.
I know Benjamin Franklin was a napping man, with some sources clqining he slept for 4 hours at night and then an hour after every meal. And anecdotal evidence, when I was in military training where I only had 6 hours of sleep a night and a 2 hour nap after lunch, I felt like a king after my body adjusted.
Interesting. I'd love to say I have this problem, but I end up staying up for 5 hours if I randomly wake up in the middle of the night even if I've only had 2 hours of sleep at most. Maybe if I adjusted my sleep pattern to sunset it would normalize.
>1. Did people wake up at sunrise and sleep at sunset or did they sleep a solid 8 hours a day? Did this continue even when days were especially short around Winter?
I heard certain cultures would sleep in two four hour blocks. Wake up in the dead of night to do more chores or stoke the fire, then go back to sleep.
>3. Did the invention of artificial light for mass use such as the light-bulb drastically change human sleeping patterns since its creation?
I would think so, from the first question a consequence of artificial light was the end of the previous sleep cycle.
It literally depends on your own sleep cycle(based on the ~24hour clock) what do you mean. I woke up at 6am everyday to get work done and be back at my shitty off campus apartment by 7pm. Eat and chilled until 9 or 10 before i got drowsy then fell asleep. I was able to get up around 6am even on weekends for 6 weeks until I fucked it up by forcing myself to sleep-in until 12pm( by just not getting up) later.
