- light availability matters, like how much lite you are exposed to in the morning, during the day and in the evening.
- how it affects other parts of your live (e.g. how reliable you can keep the rhythm)
- the body has a natural tendency to associate low, warmer light with "time to slowly go to bed", how likely are you to mess that up?
- how does it fit in with fitness and food?
I personally have a supper messed up sleep cycle.
Through one think I know reliable is that it's hard for me to stand up at any time before 1-2h after daylight (not twilight), which living in the northern hemisphere means in winter I have a hard time standing up before 9-11am. Which messes with food intake and daily activities.
At the same time it means that there is quite a long time in the evening with a constant not to bright light (room light), which messes with my body knowing when it's time to sleep.
But having bight (indirect) "neutral" or "daylight" light around my work desk, "warm" light in my living room area and reducing it over time before going to sleep does help a bit. Through it also creates a light cycle detached from daylight ... which can be a problem, too.
EDIT: Anyway: You are _much_ more likely to have subtle negative effects in your live implicitly caused by a less day aligned sleep cycle then you are with a day aligned sleep cycle. The more "off" your cycle is the more likely it will implicitly cause negative health effects, and the harder it gets to offset them.
