Sleeping In Rooms With Even a Little Light Can Increase Risk of Depression, Study Finds (iflscience.com)
Japanese researchers have found that even the slightest slither of light when trying to sleep could be linked to a heightened risk of depression, according to a new study published in The American Journal of Epidemiology. IFLScience reports: The reason behind this link is unclear, but the researchers believe it might be to do with the human circadian rhythm, the 24-hour cycle that tells us when to sleep and wake up, among other things, that is "programmed" by environmental factors. In the case of humans and many other creatures, light influences how much of the sleep-inducing hormone melatonin is pumped into our bodies, meaning we feel awake when the Sun rises and get sleepy when the Sun sets. This system works like a charm when there's only sunlight, moonlight, and a campfire to think about. However, the modern world is beaming with almost constant exposure to artificial light. Light at night (LAN) in a bedroom -- even a flash of a digital clock or streetlight creeping in from a crack in the curtains -- could screw with our natural sleep/wake cycle. The team behind the recent study assessed the sleep of almost 900 elderly people with no signs of depression. They found that people who slept in a room with 5 lux of light or more at night showed a "significantly higher depression risk" than those who slept in a completely dark room. For perspective, a household room with its lights on is around 80 lux and 10 lux is a single candle from 0.3 meters (1 foot) away.
For comparison in the other direction.
If she is in bed and I leave the downstairs stairwell light on, on the other side of the house, she will get up and turn it off.
;)
When I am downstairs in my office, I come up everything is dark. I have a routine, of feeling the walls and getting to bed like a blind individual. Not that my bad eyes are very good anymore.
Me, If I go to bed early, I turn her bedside lamp on and drop off to sleep.
Just my 2 cents
Some US jails are as bad or worse than prisons.
Not just never dark, but never silent, and they also make it impossible to get 8 hours of uninterrupted sleep--recent (and multiple) studies have shown that sleep deprivation can cause actual, irreparable brain damage. Not to mention in some cases develop into neurosis.
When I travel on an airliner I make sure I bring an eyeshade which blocks ALL light from my eyes when the eyeshade is in use.
I recommend using an eyeshade to anyone who needs to sleep despite ambient light.
It works !
I keep my room pitch black after having years of problems with sleep. Absolutely no electronics in the room helps as well; no tv, no cell, no charging watch, no digital clock. Only thing I have plugged in is a lamp.
I hate fat people.
can't take pics black hotel rooms and have to play with doors / windows to get some light but not full blast
When sleeping in a room with light pollution, I must cover my eyes (dark silk velvet works best) AND my forehead. Several friends polled do not notice any light leaking through their forehead. Do I have a hole in my head? Opinions regarding this phenomenon welcome. -arwen
Listen you guys, I'm telling you this because I love you all:
If you have a computer or router or modem in your bedroom, cover the LEDs. It makes a huge difference. Get it nice and dark in there and you'll get the best sleep of your life. Turn the computer off, and if you've got one of those goofy gaming mice where the LED lights don't turn off when the computer goes down, cover it with a dark cloth.
Also, get yourself the dimmest possible night light and put it in your bathroom (and in the hallway to the bathroom if necessary). When you get up to whiz, don't turn on the bright bathroom light. You want to stay as close to sleeping as you can without peeing in your pajamas.
Those circadian rhythms don't play. If you mess with them, you will start to feel like shit. If you become in harmony with the cycles of light and dark, you will find happiness, or at least you'll feel good.
Seriously. I'm not fucking around. I even want the haters and losers to take this advice. Cultivate your sleep. Sleep is your friend.
You are welcome on my lawn.
risk of depression vs risk of eaten by a grue
I've slept in the same room as my computer with a white LED monitor back light for the last seven years. It's indirect and faint so it shouldn't affect sleep cycles right?
I never considered something so minor being a sleep deterrent.
That's why I always pack black electrical tape on any trip. Those especially annoying little LEDs get a little bit, and it's easy to clean up afterwards. Same with new computers - they get a heavy dose of electical tape where the LEDs can't be disabled - for some reason, raw power of case LEDs seems to be major priority in case design.

Okay. Let's have the pedantic reason why they aren't the same. You know you want to.
I installed blackout roller shades in my bedroom. Took apart the smoke detector and put tape on the LED inside it.
In the summer, light still comes trough the edges of the blackout roller shades so I have been thinking about a solution to avoid that, perhaps a some sort of rail they run in to get the last part.
In the summer it doesn't get dark until 22:00 and gets light again at 05:00. And then there's the street lights out side.
I don't understand how people can sleep in those bedrooms with large windows without curtains at least not in summer time.

Prison: for storage of felony-convicted incarcerations, usually at least 1+ years
- states and the feds have prisons
Jail: for = 1 year low-risk felony sentences, misdemeanor-convicted incarcerations, and innocent people awaiting (sometimes multiple *years*) for due process in court.
- cities and counties have jails
Ask any former inmate which they were in--it's about like asking whether someone is from New Zealand or Australia.
Okay, I'll bite. Google "us jail vs prison". One of the first hits comes up with:
[Emphasis mine] The original point was likely that local law enforcement, especially in the more remote locales, are often more brutal (and other consequences of being strapped for cash) than enforcement in federal facilities.
For me, I moved all networking equipment out of my bedroom into a dedicated wiring closet. This reduced noise and eliminated light entirely. My desktop however is still in the bedroom. Others are suggestions electrical tape. That shit is nasty to peel off later. Also, it isn't the best at blocking light. I work in photography a lot, and we use gaffe tape on set. This stuff is more expensive but well worth the price to block out light. It is a rough matte texture rather than glossy. It doesn't stretch at all like electrical tape. It is earlier to tear strips off. And the adhesive is much easier to pull off objects, with the advantage of not leaving any sticky residue. This stuff is often times nicknamed "Photographer Tape" because of all of these properties. I had to use this to block out the power LED on my computer case, which for whatever reason is still fully illuminated even when the computer is in sleep mode. (no, this isn't a wiring issue with the pins in the wrong mobo header, this is a pre-built HP workstation with proprietary header)

The disconnects in academic research are due to the overwhelming volume of information.
"Artificial Intelligence" can help but is not reliable in terms of accuracy.
And finally Europeans are too egotistical to recognize the contributions of people like me who don't follow their doctrines.
... a justification for my wanting to shoot out my neighbor's back porch light with a pellet gun. And all the other outdoor lights that people feel they need to leave on all night long. We don't need the city to keep the street lights on---the residents are supplying their own. Reminds me of the time we lived out in a remote rural area outside of town and everyone who moved out there felt they needed to install a huge dusk-to-dawn light as soon as the moving van drove away. They couldn't be bothered to put it on a motion sensor---just leave the damned thing on all night long.
But when you cover your eye, most probably you don't cover the bridge nose arch properly, up and down. This is the same trick people use to "magically" see stuff when having a blindfold, either stage magician, or scammer (which is why when james randy tested those pretend people seeing with blindfold, he made sure to properly cover above the bridge nose arch and below so they could not peak either above or below). In your case the bit of light filtering is enough. But your forehead is utterly opaque, trust me on that one ;).

This makes perfect sense. Even if you are in a good mood and suddenly the light goes dim in a silent room you will start grtting dark feelings.
Ok now do the same for sleep deprivation and forced isolation beyond any real world security risk to the point of mental health and actual health issues, plus beatings and the rest. Be a real pedant about it all for me.
Some years ago I heard that shrinks were playing with the idea that there might be TWO circardian clocks, and that the manic/depressive cycles of bipolar disorder might be the beat between them if one of them didn't sync properly to the day/night cycle, but free-ran. (This could explain things like the wildly different length of different people's cycles and how depression can be alleviated TEMPORARILY {like for a few days} by shifting wakeup time forward a couple hours - though doing it repeatedly doesn't work.)
No idea if anything came of this or if it turned out to be bogus.

Maybe you should not believe everything you read on Wikipedia?
A simple Google search would have clearly explained the big difference.
Did the methodology eliminate the possibility that the sort of person who needs light to sleep is also the sort of person who is likely to get depression by randomly assigning folks to the groups, or were the groups simply divided by what their sleeping situations already were?
I can't read the whole paper, but some things seemed to imply they did not.
The distinction is not pedantic at all.
Jail is where you go when you're arrested. Prison is where you go when you're convicted. One is short term, one is long term.
There is some overlap, with jails holding prisoners with short sentences, but this rule of thumb is a good one.
You are welcome on my lawn.
OK, here goes.
Because prison is for longer sentences, inmates make more of an effort to survive, and to survive you need sleep. It can be quieter at night in prisons because people housed there know they're going to be there for a while.
In a jail, there are more health issues. There's a lot more acting-out. Inmates only have a limited time to establish their place in the pecking order, so there's more competition. Prisons have more established social structures.
Plus as someone else here has pointed out, local law enforcement tends to be less professional and more corrupt, so they promote a violent, zoo-like environment. For examples, see "Sheriff Clarke" and "Sheriff Joe Arpaio". The vast majority of people who work in law enforcement will tell you those guy are both a disgrace.
You are welcome on my lawn.
Although anecdotal, I used to be pretty obsessed with optimizing sleep (pillows, mattresses, light conditions, minimizing noise, sleep gadgets, etc) and I followed the "no light at all" thing. My sleep was fine but it made little difference on my happiness. In fact, I was usually depressed.
After that, through circumstances out of my control (in another country) I had to sleep in a room with a very bright ceiling light on (about 20 feet up). It was harder to fall asleep, but my happiness was significantly higher.
Again, there are innumerable variables so I can't make much judgements from that but I know first hand that light or lack of it during sleep doesn't *always* cause happiness/depression because there is much more to it than that. Just wanted to post a differing idea. YMMV.
This is the American definition where jail and prison have different meanings. In other places (such as the U.K) they are the same. The word is used interchangeably.

As a typical /. subscriber I have a particular difficulty in this respect. Because the sun shines out of my arse.
Darkness, darkness, be my pillow. I was a shift worker for years and had to try to sleep during the day. I warned my family I would be in a bad mood and to please forgive me. I put heavy dark curtains and pull down shades on the two windows. That helped but I could hear my sons playing and cars driving by so I wore earplugs. That helped. During the summer the room would get warm and I installed a window air conditioner. More noise. I slept for four hours then woke up. I still wear a sleep mask and sometime use earplugs at night. It;s one-thirty AM now .
So, in Finland:
Winter: No sunlight -> No vitamin D -> Depression.
Summer: Constant sunlight -> Depression.

That would be sliver of light , not slither. Huge difference.

"Programming is life, the rest is mere details"
We get it, you obviously served time in a Turkish prison. Maybe the constant anal ass poundings you received from swarthy prison mates were the cause of your brightened mood?
I put electrical tape over every status LED on my chargers, some of them were extremely bright. I don't need to know that an entire row of wall warts have power from one surge protector.
We have a TV in our bedroom, and I can sleep just fine with it on if my wife is watching, but when it's off, it has a white LED status indicator that is on at the bottom, and that light drives me crazy -- thinking I might have to either remove it or tape it. My alarm clock drives me nuts, too, so I have to turn it away from me, and if my wife tries to read her kindle it often will wake me up even if it's not facing me.
Anyway, I don't think it's all this that makes me depressed, I think it's my job in IT that does that...
The curtains in my bedroom are rubbish AND I have LEDs from a my smartphone and Bluetooth speaker (needed for white noise) bleeding light. I bought a bunch of surprisingly good eye masks from a 100 JPY shop (Seria) which keep out the light until the horribly early time I have to get up for my long daily commute.
really a "slither" of light
do not mean sliver or is this light sinuous
Someone needs to clue hospitals in on this. I recently spent nine days inpatient because of complications after laparoscopic surgery for cancer. I was supposed to only be in for one night, but due to serious internal bleeding, ended up in for the nine days. This in turn made my normally high blood pressure very low, which caused me to pretty much be bed bound for most of the time. While I was allowed to sit up in a recliner chair, it required a nurse to help me do that. They alarmed both the bed and the chair to keep me from getting up on my own... and preventing me from getting up to shut the door.
The thing that was huge a problem for me was all the light (plus the noise) when the night staff would come in (and turn the lights on so they could see to take vitals and draw blood), and then leave the door open when they left, even though I kept asking for it to be closed. The entire time I was in, I got no more than about four hours sleep every night. I also had one of the floor's WiFi access point directly above my bed, with a bright blue indicator light that was bright enough to read by.
I've seen other hospitals, and they are all like this.

Drunk/disorderly type crazies get sent to jail, not prison.
I know for myself I sleep just fine with a little "warm" 4200K light. Light does seem to affect me more in the mornings thou when it comes to waking up. It's really hard to wake up in a pitch black room even with the alarm clock going off. A bit of lighting then seems to help. I'm guessing for me a bit of light isn't a problem.

If a light sleeper sleeps with a light on..
.. what does a hard sleeper sleep with
Spent a large portion of my summer vacation in a cabin in Nova Scotia that had no electricity and no one around for miles. It was the absolute best, most restful sleep that I've ever, ever had. Pitch dark every night.
Now that I think about it again, it's time to look for some good blackout curtains. Any recommendations?

Secession is the right of all sentient beings.
Perhaps people who live in the city have a higher average of >5LUX sleeping conditions, while people who live in the country have a higher average of 5LUX sleeping conditions. Perhaps people who live in the city have a higher rate of depression than people who live in the country.... I wonder what other data they have on the study group to correlate and rule out other possibilities. I also would think, that on average, a more lighted sleeping area may be nearer to more noisy conditions like roads, traffic, airports? I wonder...
i live in complete darkness so i can be a happy motherfucker and be happy as fuck
It always makes me laugh, when people worry about tiny LEDs in their bedrooms preventing it from getting dark, when they have fucking huge and ugly streetlights right by their windows.
I've spent my entire life living out in the country, with no streetlight around for miles, and my bedroom, even with a bunch of tiny status indicators coming off my various electronics, gets a lot darker at night than any house I've ever been in that had a streetlight nearby.
So for tens of thousands of years, humans who slept by fires were depressed? Unlikely.
If I had an account I'd mod this. It takes years to get used to and if TFS is valid, that's a long time to be depressed.
Well, there’s depression and there’s depression. To overly simplify, there’s deep sadness and there’s an inability to function well independent of any deep sadness. So what are they talking about in the study? Apparently not explaining, and the study group is limited to older people. So the significance of the finding is kind of mushy.
