I have been feeling sad in the evenings a lot this winter, and it’s been especially bad the last few nights – a bad mood will come on suddenly, sometime in the evening, and I’ll spend the rest of the evening trying unsuccessfully to think of ways to fix or salve it. My best guess is that this is something like SAD, since it’s close to the winter solstice, and the bad moods have a 24-hour periodicity.
Usually I’ve noticed the bad mood coming on at maybe 6 or 7 PM, but today I started to feel kinda bad around 4. I noticed that the sun happened to be setting outside, and that f.lux had just started to make the colors on my computer more orange.
So I turned f.lux off and closed the blinds, and now I don’t feel sad.
Could be placebo or coincidence, but it’s an interesting angle on the problem. I completely forget i have f.lux most of the time, but given how much I use my computer, it’s having a big impact on the kind of light I am exposed to.
And it’s deliberately synching up that light with the light outside, so if the light outside is making me depressed, well … that seems obviously bad.
I know a lot of people have f.lux installed, and people generally talk about it like it’s an unalloyed good, so I thought I would post about to encourage others to think about whether f.lux might be screwing with them.
(I’d expect there to be multiple patterns here – people who get depressed in winter because their circadian rhythms get delayed may benefit from f.lux since it stops the computer from advancing their phase when used at night, but if some people who get depressed in the winter due to an overall decrease in blue light exposure, f.lux will only make that worse.)
