> Our bodies don't really time to the sun anymore since the invention of artificial light and blackout shades
Is there any research that shows this? I’m not aware of any. In fact there are social reasons people might stay up late. It is a mistake to ignore that.
They had this discussion in Iceland recently (which is on permanent DST; and with heavy population centers way north of Alaskan population centers) and health officials were pretty keen on moving to standard time precisely because teenagers have a hard time waking up so often before sunrise. Yes a big part of the year will always be before sunrise, however on standard that part is shorter.
This is not exactly what we are talking about. Yes artificial blue light disrupt our natural sleep rhythm. Yes there is research that shows this fact. But, that does not mean that we are not effected by the sun.
This research would need to show that blinds and artificial blue light would be sufficient to replace natural sunlight for setting the sleep rhythm to a healthy level. The existence of flux actually suggests the opposite is true, and people need software to prevent artificial blue light from disrupting the sleep rhythm.
