No such thing as natural morning or night person. Peoples rhythms are thrown out of wack due to artificial light. Get rid of the artificial lights and we all go back to our natural circadian rhythm. We start to get up and go down with the sun. All you need are glasses that block blue light. Try it.

... and possibly enough vitamin D early in the morning (e.g. before 10am), either as a supplement, or, preferrably, by exposure to the sun. And also quite a bit of exercise. Or not. Anecdata are plenty, scientific evidence is scant.

  calling bs on the "blue light glasses work" as well. No direct scientific evidence.

    There is no direct evidence but proxy evidence. Atleast for me, using a red-tint filter on a phone or computer screen helps a lot with eye fatigue and afaik also with sleeping as I tend to be more tired when waking up after not using such a filter. Additionally, I'm fairly certain that there have been numerous studies that found that the color of light heavily affects the circadian rythm, especially the blue component, not only in humans. By proxy any blue-light filter should have similar effects. And by proxy of that a blue-light filtering pair of glasses should too.

    To be clear, I was not calling bullshit - I experimented with UVEX blue-blocking glasses, and so a marked difference in "natural" sleep times. Similarly with early morning Vitamin D, and exercise, and I am not the only one. However, I am not aware of any reasonably objective evaluation of these claims, so I don't consider them "truth" or "science" - they are anecdata, which might be interesting, but not science.

That would be a real bummer living in the far north/south. Kind of boring to go to bed at 3 in the afternoon... :/

That's not what sleep specialists say. Citation?
