We wondered this too - we surveyed people who were installing f.lux for the first time about what they cared about - "eyestrain vs. sleep". 90% of people said better sleep, 60% said eyestrain. So both are important.
But imagine you get a job that requires you to be up at 8AM (and you want to take it). Do you have control of that part of your biology or does it have control of you?
The theory is that your environment is one of the major things controlling your biological timing, and the indoor spaces at least are ones we built so we should understand what it takes to change them.
- derefr 9y ago> Do you have control of that part of your biology or does it have control of you? I've personally found that I have a pretty heavy degree of control over it via the orexin† pathway: if I force myself to wake up and eat immediately for a few days at 8AM, then my body will associate 8AM with eating and shift everything else around (when I get hungry; when I get tired at night; etc.) to ensure I'll be wide awake at 8AM to "catch that meal" (that in the environment of evolutionary adaptedness was probably a rabbit or something.) † https://en.wikipedia.org/wiki/Orexin https://en.wikipedia.org/wiki/Orexin
