This missed the fact that there’s a massive body of evidence showing people have different genetic predispositions to being morning people versus night owls

- colordrops 8y agoI don't think that's what this article is about. Everyone has predispositions. There are some techniques that work for many people. This person is just sharing theirs in case it helps someone else.
- Bahamut 8y agoEven so, this can be changed via environment. I had a big predisposition to being a night owl in the past, often sleeping between 1 - 3 am, but after I enlisted in the military, being an early bird has stuck with me ever since. I often wake up 5-6 am and go to sleep ~10-11 pm, sometimes closer to 9, sometimes later. For me, not using alarms to wake up in general, and sleeping earlier works wonders. I also adjusted to having less sleep as a result of the forced sleeplessness of military life.
- mykowebhn 8y agoExtremely small sample size (of two), but I used to be a night owl, and in my old(er) age I've definitely become a morning person. Same with my wife. It's not unusual for us to be in bed by 8pm. My point is that being a morning/night person might be changeable.
- rsuelzer 8y agoIt is a fact that as we age we prefer to go to bed earlier. There is a good evolutionary explanation for this. It makes sense that teenagers with better eye sight would stay up late to watch over the tribe / livestock at night, this predisposition for younger people to be night owls benefited the survival of the species.

- listenallyall 8y agoThis 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.
