This is pure speculation with zero scientific evidence, but I believe that some (many?) people's internal clock is not tuned exactly to a 24-hour day.
People have wide variations (in some cases, defects) in virtually every physical and mental dimension we can measure. The idea that everyone's body clock is precisely tuned to 24 hours just doesn't seem right, it's far more likely to be within a range, perhaps between 18 and 30 hours. With that logic, I speculate that many "night owls" are people whose body clock doesn't reset properly until 26-28 hours from the previous day.
I would love to know if there are any research studies along these lines.

- listenallyall 8y agowow, thank you
- xkcd-sucks 8y agoYeah, Eric Bittman at Umass Amherst is one person that reasearches circadian biology you can pick up some lingo to search for from papers. Generally speaking, no critter's circadian cycle is 24 hours. They are all "entrained" (e.g reset) by stimuli, among which (blue) light is the most well studied. And non-24 hour circadian cycle in people can be diagnosed, and it is possible to be considerd a disability in the legal sense. But it is tricky to get testing, and insurance coverage for testing.
