It's called "social jet lag". Yes I know about sleep hygiene.
It's absolutely true that a lot of modern-day problems with being tired come from bad sleep habits. What I'm talking about is a real phenomenon that isn't being in front of a screen too close to bedtime. If anyone wants to know more, here's a 3-minute video from AsapSCIENCE about what research shows.
The cicadean rhythm is synchronizing to the light of the sun, temperatures, when you eat, when you exercise and other kinds of routines, but what happens when we remove those?
Scientists in the 1960s set out to find out. From the late 1960 to early 1980s they put test subjects in a bunker. They found out that the human cycle is longer than 24 hours. The average might be around 25 hours, but not all. The longest was 50 hours.

Another well known experiment happened in 1989 where Stefania Follini was isolated in a cave for 4 months. Her internal clock went into a 48 hour cycle.

Of course these are extremes and not very useful knowledge for anyone who sees the sun daily or have actual stuff to do on a regular basis.
However it shows that out sleep cycles are very much dependent on being synchronized to what we need to do.
Looking at people in hot places, who sleep (siesta) when it's too hot outside, or people from non-industrial societies who might be active both during day and night and sleep in between, it's pretty obvious that the 9-5 productive cycle is not at all "natural" for anyone.
This tracks with my experience when I decide to take a long vacation where I don't do anything. I naturally stay up later and later until it loops around.
This was true for me in my younger years especially, I ran on about a 32 hour cycle. As I've gotten used to my weekday work routine I'm much closer to a 28ish hour routine now.
I actually used to do this regularly when I was in a small community. I walked my dog every night at 1-2 AM, and let my neighbors know I'd keep an eye out for anything funny.
So here we are still doing our thing... But we only ever get disadvantaged as a result.
Then it's openers vs closers. Having both and some in the past, opening/day was easier physically. Cash register, rando merch projects etc. when my shift was over all I needed to worry about was finishing up what I was working on and communicating what's left to the next shift.
I think it's more flexible than you think. In my single 20s I was a night owl because I stayed up late playing video games and got satisfaction out of that. Now in my 40s I'm up at 5am because that's when my family is still asleep and no one needs me for anything, and that's a nice if not rare feeling.
It's super helpful to people like me who have been suffering their entire lives. It's great to feel heard and validated, but the real value is being able to learn about myself. I've never been a morning person and have trouble sleeping at night. It's really nice to hear something other than "you're just not trying" or "try counting sheep". It's a lot better than just thinking I'm flawed. I wish someone would have told my parents this when they used to scream at me for sleeping in too late or not being asleep when they wanted me to be.
It was the same way with my adhd. My parents and teachers kept telling me I was just lazy, or didn't care when I felt like I was working my butt off. Being 'worse' then everyone else ate me alive and I'm still suffering for it. It was the same with my brothers autism. It was the same with my chronic depression. I wish I was born in this age of self reflection and mental health awareness, and for the sake of all the kids like me I really hope we keep pushing forward.
I'm sure your comment was sarcastic, but I'm hijacking it to dump 20 years of built up trama,, and to let the world know how thankful I am that we're starting to accept these labels as more than just flaws. They're really, really helpful.
Edit to say, I just read the other comments and realize you weren't being sarcastic. I hope my post helped point out some of the reasons things like this are becoming so important to people.
I get why people are downvoting but I agree with your point.
You don't need to be part of a community or fall in a specific identity term to be valid. Just be you. You are valid as you are, no matter if your identity has been given a name or not.
All identity terms are made up anyways, it's just our dumb brain's way of simplifying and denaturating complex stuff in a way it can understand
Mate, I do not care what people think about me being tired every day I need to wake up early. However, can you imagine the satisfaction when I could finally look my father in the eyes and say to him to can it because it's actually goddamn proven that this shit is real and unchangeable, no matter how many bullshit methods he thinks of? I had tobput up with his yapping on the matter for most of my life. Goddamn GLAD to be done with it.
My natural cycle appears to be wake up in the afternoon, fall asleep just as or after the sun comes up. Varies with seasonality.
I also sunburn extremely easily, prefer to be a recluse 99% of the time, and lately im dressing in black pants, a black jacket and whatever undershirt.
Having been injured multiple times and having tasted my own blood... I don't seek it out through self harm or anything like that, but I do find the taste... interesting, and unique.
Doctor Scientist Person, is Vampirism a genetic disposition, or a phenotypical expression based on environmental factors and epigenetics?
No, I like garlic in reasonable amounts, and I love running water.
See it actually gets worse. I am originally from the PNW, love exploring waterfalls and streams...
But also I have at various times in my life had friends tell me that I appear to be sparkling, I go check in a mirror and yep, somehow, some little reflective ... piece of sand sized object or objects are on my face.
Never once have I had glitter in my home I somehow could have gotten stuck to my face, never been able to figure out where the stuff comes from or what it is.
It often happens when I am in a very good mood. And it isn't sweat. Its always tiny specks I can flick off.
Also, it took me forever to figure this out until I was determined to be Autistic so at least thats a reasonable explanation: I legitimately do have a heightened hearing sense compared to basically everyone I have ever met.
Even worse, I at one point met a person who said that they had escaped from an apparent actual Vampire kind of abusive harem sex cult type thing...
Yeah. I have never even read Twilight but uh ...
Yeah awkward autistic pnw flavored minor vampire twink guy here, apparently.
society does not work on a 9-5 schedule. Ever since we stopped living in tribes every society has had to have people who are up when others are asleep. Most people like to sleep in the night and be awake in the day. Thats ok
