It seems the problem is not that _everyone_ needs a full 8, but that many people _assume_ they don’t need that much, even though they do.

I don’t sleep 8 every night: sometimes it’s longer, usually it’s more like 6, but either way I don’t use an alarm to wake up.

The key for me was to prioritize my sleep health by minimizing screen time before bed, going to bed consistently at the same time, and always leaving enough time to get 8 full hours if my body ends up wanting it.

I don’t _always_ need 8 hours, but it makes a huge difference when I do. And empirically, my well being—physical and mental—improves substantially if I am going out of my way to tend my sleep health.

Anyone who isn't using flux[0] after 8pm is seriously hurting themselves. Once you use it, you can't go back.

People said that, and flux and other apps came out. Then Apple added it too (and perhaps other OS makers).

But there's this too - and increasingly more stories like it:

Interesting, thanks for sharing those articles. redshift lets you adjust brightness in addition or instead of color temperature (there is a Windows version but it is command line only, doesn't look like it supports macs and does not work with Wayland). Someone mentioned brightness a while back and I've been adjusting both since then but I'll try just adjusting brightness and see how it works. If nothing else, it is possible that warm color temperatures might end up being similar to the issue with flashlights where full spectrum lets you use a lower brightness than red light (of course, with flashlights there is also the issue that many "red" flashlights, even some that advertise as being night vision preserving, aren't in the right range to actually preserve night vision). It does seem like I could lower the brightness a bit more without the warmer color temperature.
