The problem I have with this theory is that during our, er, "formative
years", evolutionarily speaking, we lived in areas where there really
wasn't more than a few minutes difference between winter and summer
day/night length... so according to this, truly "paleo sleeping" would
mean far more sleep on a regular basis, season be damned...
Then there's the generalized concept that it's prey that generally shuts
down after dark--most predators seem to have more nocternal potential...
But personally, I often sleep odd hours so I have, while not completely
room darkening, certainly room-significantly-dimming curtain/blind
combinations in my bedroom! I figure it's certainly paleo to sleep when
you want/need to :)
