You use your electric lights to help counteract all that electric light exposure you get all day?

I mean, it's not the electricity that is the problem, it's just the total light level.

The human brain and eyeball take all kinds of sleep readiness cues from the amount of light in the environment.

I use some dimmer switches, and some lamps with low-lumen bulbs installed.

Sometimes I set up I timers to make the brighter lights turn off and the softwer ones turn on, as my bedtime approahes.

Most phones will also automatically adjust their screen to match the light level in a room, so addressing the room lighting also helps address the light being output by the phone screen. PCs need more help.

Linux Mint has a nice option to adjust monitor brightness and hue based on local time of day.

We also now know that the amount of blue light specifically influences sleep patterns more than other spectrums of light, so I have filters on my laptops and phones that change the screen hue toward orange after certain hours in the evening.

Back when my phone was too stupid to adjust it's own light level, a blue light blocker made a huge difference. Now I don't notice it as much - probably because the phone puts out far less total light, in the evening. But I figure a blue light filter doesn't hurt, even if it isn't doing as much as it used to.
