There is a good research base showing that there are gene variants for human response to light in resetting the circadian rhythm. The evolutionary history of this is so deep that the same gene variant appears in fruit flies, where it was first discovered.[1] But even at that, light influences everyone's circadian rhythm, and a smart, timed use of light can help you reset your biological clock. This article is an interesting account of one person's effort to do a habitual reset that seems to have worked. Benjamin Franklin wrote, "Early to bed, early to rise, makes a man healthy, wealthy, and wise," and there seems to be a social and economic advantage in being a morning person in many life circumstances.
