Pre-modern views on this is that you are supposed to align with the natural order of the world. If we are waking up at the same clock time and it is darker, we are not living in a way that is aligned. It is darker because it is closer to winter, a time when emotions, metabolisms, and such all shift towards less activity and more reflection. Kids went to bed because the whole family, the whole community ran on sunup and sundown.

I'm not suggesting we go backwards towards a pre-modern time. We do have some great flaws in what we are doing now (modernity). Our civilization runs on clock time and is very productive, yet we live in very dysfunctional and unhealthy ways.
