The best thing to do is to take commonly held knowledge and make a study out of it.
Maybe the next study could be “live king cobra in the bed results in sleep reduction”.
Probably a book and a TED talk to go with it.

What can we do about the tendency of research articles to get their big flash of publicity before undergoing peer review?

Sorry for exposing my personal medical data, but... I literally cannot fall asleep without at least some light. So I sleep with lights on. Trying to be like normal people would only make my overall health worse.
Is this a medical condition that has a name?

Maybe they're exposed to light at night because they're awake at night more often, possibly shift workers, which we already know is unhealthy. I doubt just having light on is causing the effect.
giraffe_lady · 14m ago
Yes they tracked hours of light exposure (above some threshold? I don't see that they say.) and found this result in the 90-100th percentile. So almost certainly night shift workers.

does it make a difference if it's warm or blue light?

> including physical activity, smoking, alcohol, diet, sleep duration, socioeconomic status, and polygenic risk
Wondering how much of this is due to geography and air quality. City centers have relatively bad air quality and a high amount of ambient lighting at night, compared to non urbanized areas.
The cardiovascular effects of poor air quality is arguably well understood.

My bet is that cardiovascular problems cause light exposure at night.

Most studies pull from urban populations and usually contrasting with a rural population is done for a demographic comparison. (Most people also live in cities.) The study was careful to use personal light monitoring, so urban residents who nonetheless find ways to live/sleep in the dark would be included in the study.

Is this detecting people who work overnights?
loeg · 14m ago
Almost certainly some kind of 3rd variable, yeah.
giraffe_lady · 12m ago
I believe so yes. They tracked hours of light exposure at night over a week, and found this result in the 90-100th percentile. The 90th percentile here is pretty much going to be people working at night yeah.

Each participant wore a wrist light tracker for 1 week.

If the article had said regularly having to go to work before 9:00 a.m. predicts incidence of cardiovascular disease, would we be having the same conversation?
trollbridge · 35m ago
Good catch, although there are plenty of studies and even metastudies on that topic (eg https://pmc.ncbi.nlm.nih.gov/articles/PMC11129786/ ); generally speaking, the healthiest people are those who work "normal" day shifts with "normal" hours (full time; not part time; no overtime).

So use the toilet in the dark?
trollbridge · 36m ago
I've always wondered about people who say that... there's enough light (particularly when it's not a new moon) to see to go the bathroom, but maybe my eyes adjust to the light better?
_heimdall · 1h ago
Do you have to turn the light on to use the toilet?

Do you have to leave the bed?
Krasnol · 1h ago
I do have to, this is why I bought one of those IKEA smart bulbs and made it dark and blue. If I get up at night, I use my watch for light.
brador · 43m ago
Why blue and not red/orange?
joe_the_user · 1h ago
No but I think many people in fact turn the light on when using the toilet.
