Huh, that's kind of wild. I'd assumed that blocking all light out at your eyes would do the same trick, I'll have to try the blackout curtains. Thanks!

I use a mask too, but it moves around when I sleep. Even properly positioned I haven’t found a mask that doesn’t leak around the edges.

I have this problem, too. I've tried probably a dozen masks, the best was one that I got overseas in Southeast Asia and it has no branding, etc.

My mom always told me I was certainty

If only I had more time, I'd love to gather up these images with these fake words and create a dictionary. I know that there are thesewordsdonotexist type of sites, but this seems different. Luckily, I have no free time to find myself down that particular rabbit hole.

One night? You could probably repeat this experiment with fart stench or any other obnoxious irregularity and find impairment of glucose tolerance at a decent p value. I see the headlines now: "Fart stink during sleep impairs cardiometabolic function." So yeah, guess the wife is getting diabetes if I don't move to the dog house.

This article refers to "moderate" (100 lx) light exposure - this amounts to an overhead light on in the room for the entire duration of sleep. I would say an overhead light is a significant amount of light, but wonder how low the threshold is for sleep disruptions. Living in an urban environment, there's a non-negligible amount of ambient light that makes its way in. I don't use a set of blackout curtains, but I know…

> I don't use a set of blackout curtains, but I know several friends that say it makes a real difference. Maybe a year ago, I was planning on having a sleep study done. At some point in my 30s I stopped feeling like I was recovering when I slept. I decided, however, that there were some things that I could work on improving before having a sleep study. Most of what I addressed falls under sleep hygiene: Blackout curt…

My wife was complaining about waking up in the middle of the night. I grabbed some black out curtains. She woke up the next day feeling better than she has for a long time.

Turns out there was a streetlight that would hit her in the face and was causing her to wake up. We didn't realize it until we got the blackout curtains.

Joking (?) aside, cheapish air purifier are reasonably efficient to help for stinks and other air issues during sleep if they have a carbon filter (IKEA ones have the option for instance). Bonus point if they can auto-adjust power depending on the air status, but I don't think that's mandatory.

I agree -- our bedroom is small and benefits from even a simple filter! However, my point was to humurously criticize the study title for sounding too conclusive. The study is useful as a starting point but it is pretty well known in such literature that one-night of introducing variable X can yield results showing negative short-term perturbations. X can even be something generally regarded as positive such as first night on low-stress vacation, or even the first few times people share a room with a partner. Changing a routine increases vigilance (not sure of proper technical vernacular for that, but you get the idea).

Ugh. When I was in jail I had to have a bright light shining on my face every night for five years. Cover the light and you went to the Hole.

At one of the jails I was in the deps would put the dayroom TV on at full volume all night long when they were pissed at us. between that, no pillows, and 3:45 AM breakfast, sleep hygiene isn't terribly valued in county

Were we in the same jails?!

I think this shit is universal across county jails. Prisons get more litigation, but jails are hard to litigate in.

I fucking hate no pillows, 3AM breakfasts.

I sued and got the breakfasts legally changed to 6:30am. That got me another 10 days in the Hole.

Hope this discovery will influence hospital lighting policies.

I always bring a sleep mask and ear plugs with me to the hospital. It confuses me that they don't hand them out! Sleep is essential for healing. I have often had nurses in hospitals tell me to sleep, but I've never had a nurse offer me ear plugs.

Blackout curtains are great for sleeping, but I have trouble waking up and getting out of bed when the room is still completely dark (when it’s light outside in the AM). Recently bought some Hue smart lights to simulate sunrise with blackout curtains which is helping. Next up, motorized blinds that open at a scheduled time. (#firstworldproblems)

Here in Germany they have metal shutters that vertically descend and black out all light and sound. It’s common on most windows. They are permeated with little holes that allows light and sound in if they have not fully descended. If they have then the little holes are folded shut. I’ve found the same issue where if they’re completely down waking up is hard, so I leave the top two rows of holes open to let in natural…

Rolladen? Yes, I remember those! My wife and I lived in Belgium at the time, but we visited her sister and brother-in-law in Germany on a few occasions.

Yes, I want! Have wanted for years, in fact. Hard to get here in the US, however.
