Did you ever write until 1 am, and then have trouble getting to sleep?
|Not the "Flux" I'm writing about.|
There have been assorted studies that show that the relatively blue screen of a computer tricks your brain into thinking it's daytime. In fact, at 6400K, your computer screen is even bluer than sunlight, which is about 5600K. So when you finally close the computer, you're still in daytime mode. It takes a while for your brain to get into night time mode.
The nice people at Flux
have written a free app that will change the relative color temperature of your screen so it's warmer -- anywhere from 5600K down to the 2700K of firelight.
(It has absolutely no relationship with Aeon Flux, whose picture is to the right.)
I tried it last night. I only put the color temperature to 4500K because otherwise it seemed just a bit too orange. (The FAQ
says it takes some getting used to.) But I did feel a whole lot less wired when I finally stopped working around 11 pm.
The only odd feature of the program is that it depends on your location to determine when to turn the lighting of your computer down to night mode. So the transition happens automatically at sundown. In the depths of winter, I don't particularly want to feel sleepy at 5 pm. But it shouldn't take long before they allow you to set the timer manually.
Check it out.
