I'm a Night Owl and have been from a very young age. I also wish Night Owls were more just considered a thing in this society rather than labeled lazy or deviant. But hey, if you don't conform to the Capitalist mold, you're apparently whatever people want to negatively label you as. Unless you're a Night Auditor, Night Security Guard, Fireman, or Soldier, then you're a (somewhat) acceptable part of the machine.

Anyways, here's a BBC article on why humans might have evolved to have different sleep schedules. It's an interesting read IMHO.

Obligatory xkcd.

I've always hated this train of thought (when people call you lazy for staying up late/sleeping in).

I have been working in IT my entire life, from 24/7 data center operations to managing world-wide systems. There were times where I had no sleep, because as soon as the Americans left the office on the west coast, China and Taiwan were waking up and starting their day.

Just sleep when your body tells you to sleep, and wake up when your body wakes you up. Force fucking a time schedule is awful and 9-5 does not work for every physiology.

Amusing thought, but doesn't really make sense biologically. Your body doesn't know your geographical location. It just reads the environmental time using a bunch of different inputs and guesses at what the actual time is. Your body is actually fairly good at guessing the time, but people are just naturally predisposed to sleep later or earlier.

That tendency is influenced by genetics and also changes over time with age, but I also heavily suspect that people are actually just messing up their circadian clocks without knowing it. Try dimming your lights after sunset, you'd be surprised by how early you get tired.

What is sleep schedule?
