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.
We protect the tribe at night

Even this might be too simple.
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. en.m.wikipedia.org/wiki/Bunker_experiment
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. en.m.wikipedia.org/wiki/Stefania_Follini
Of course these are extremes and not very useful knowledge for anyone who sees the sub 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.

Being highly productive and focused for 8-9 hours in a row isn’t natural in the first place, no matter the time of day

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 did this recently with FF7 Rebirth. It might have looped twice, honestly.

Super interesting, and thanks for the sources :)
