Going to bed earlier made a big difference in my health, even though I kept the exact same total hours of sleep.
I think there's more to circadian rhythm than just "light hitting your eyes/skin". Even when I sleep in a completely dark room, with 8-9 hours of sleep, I will not feel rested when I go to bed to late. I tried adapting to it for several months when I was working late, it just never worked out. Our bodies seem to know what time of day it is, even without light. Just a thought: If the gravitational pull of the sun and moon is strong enough to cause the ocean tides, maybe it has an effect on our circadian rhythm too?
