> I bet 95+% of night owls would be "cured" in a week flat if they were allowed no glowing screens past sundown and their typical stupid-bright room lighting were replaced with warm-temp handheld lights at ~2-4 candle equivalent (actual, not "candle power")

It's an interesting theory. Problem is, without a biochemical pathway it means nothing.

Melatonin secretion & basal temperatures are both interesting avenues for research. Blue light seems to be a favorite as well.
