Light does not happen by magic and tends to not occur alone. I would be very leery of asserting cause and effect here.

There's a very long bibliography stretching back more than a decade and including at least one mouse model of depression. It's not just one study.

So does my body itself need to be protected from seeing light or just my face/eyes? I'll just get a sleep mask.

Weirdly, we now know that even the brain has light receptors. (The skull is very transparent when wet with CSF.) Night nurses know that a flashlight hitting a sleeping patients leg in darkness causes a contraction.

Sleep masks help a lot - but they aren't a full solution.

Quick plug I started curating a list of things that may help depression yesterday over on Github https://github.com/Jimnotgym/Hacking_Depression I just added this

Please consider including links to local crisis helplines e.g. [1] and [2].

On the other hand you may turn away depressed people who are not in a crisis because they don't want to be associated with the idea of suicide when their main problem is they have no will or energy to do anything ever. You might end up hurting these people by constantly mentioning suicide whenever they finally get the guts to learn about their depression. "Oh, you depressed? Here, read about suicide! Let me scare you back into your hole!"

Skimming the original study, it talks about subjects opening and closing their eyes, so I would very much assume that it's entirely related to seeing light (and not about absorbing light through the face or body). If you get a sleep mask, be sure to look for one designed to not put pressure on your eyes, which are not hard to find if you seek it out. The cheap ones you get at pharmacies and dollar stores put direct p…

Any brands you'd suggest?

The best I've found isn't sold as a sleep mask, but a "heat massage" mask with beads in it. I never heat it, I only use it as a sleep mask, the beads provide a wonderful, and comfortable, light seal.

It seems like giving half the people blackout curtains and then monitoring depression levels would be perfectly ethical, since it's expected to improve their life, if anything.

The problem with that is the placebo effect..

But the proposal was for a single-blind study in which half would have some other placebo, I take it.

Actually, they didn't touch the lights at all, they only measured the lights that people already were exposed to. They write that "an interventional method, such as a randomized controlled trial using a LAN exposure, is not possible because of ethical concerns".

I can’t imagine minor adjustments to light levels could ever be considered unethical. Is it unethical when a city installs a new street light?

Yes - it is harmful, we now know, and keeping people in solitary confinement with high light levels around the clock even more so, although common.

I think a lot of studies like this are just wrong. When I was a kid, I couldn't sleep without a light on because I'd get depressed. So later on in life if I didn't remember that, I'd think that I just had a light on and now I'm depressed. I think depressed people like a little light. Much like they say red meat causes cancer, I don't think it's the red meat. I think it's how it's cooked. Red meat is usually barbecued…

If the light is red, that's fine. Doesn't trigger ipRGCs.

Temporary rush of steroids. Different phenomenon, may actually be causing the long term harm.

You both make good points. I opened an issue to discuss. Please have your say.

They are fairly common throughout most of Central Europe. I stayed in apartment a few years ago that had electric shutters; it felt like I was living on a space ship.

The Dutch are known for not owning curtains [1]. I don't know if they have shutters though. [1] https://stuffdutchpeoplelike.com/2010/11/24/no-8-not-owning-...

The same in Denmark, but in my experience people still have curtains in the bedroom. It would be difficult to sleep (especially for children) in the summer without them.
