So use the toilet in the dark?
Buy one of those darkness-sensing nightlight plugs and leave it in the bathroom.
They cost under a $1 a month to run.

I’m not really understanding the monetary interest angle. The monetary interest in this subject is the curtain and window-blind manufacturers.
The researches here have a company who sells body worn light sensors. And if their light sensor is good maybe other researchers interested in verifying this phenomena will purchase a few units from them. But they are far from the only company making light sensors. In fact if i want to verify this study i would buy sensors from anyone but them. For the sake of having independent proof free from biases.
> they disappear into some third world country after taking their sum
What sum, please tell me? Where do you see the riches here?

My cardiologist always asks about sleep, isn't it obvious a darker room makes for better sleep

I'm sorry I can't continue this conversation of pretending the thing right there doesn't exist.
Re: Light exposure at night predicts incidence of cardiovascular diseases
#78How do they know the causal link? Can it be that people who stay up late sleep less and this causes issues, and there being light is only a consequence of staying up late?
Correlation is not the same as causation. The research indicates a correlation. Assuming causation is a classical mistake with any research. In any case, light sensitivity and sleep patterns are well linked. If you live far away from the equator, you are dealing with pretty short nights half of the year. I lived in Helsinki for a while. That can really mess up your sleep though some people manage to adapt. There's a…

That's not OK, I don't know a single person affected so (live in cca same latitude as Berlin). Have you tried some radical solutions like good window blinds or similar sun blocking mechanisms? I don't mean some cheap crap that still lets strips of light through, I mean full block. Of course if then some chopper or ambulance wakes you up regardless it doesn't matter.

You don’t have to pretend anything. Just go on and explain where you see the monetary incentives with this research and researchers. (If you see them.)

Eh, you never know with studies. They did this one to serve as a classic counterexample: https://www.bmj.com/content/363/bmj.k5094 You can almost see the grin as they wrote up the results.
To those who don't follow the link. The Beth Israel Deaconess Medical Center ran a trial on parachute use to prevent death and major trauma when jumping from aircraft, and gave half the people jumping a placebo (empty backpack) instead of a parachute. No joke. https://www.bmj.com/content/363/bmj.k5094
OK, I read the article, wondered a bit, then started to read the responses (first aligning with the one "April Fools' in December?"). I mean, what's the point of asking people to jump from airplanes on the ground, write a study on it, and waste everybody's time
But then, reading other responses, and taking into account the name of the journal, and the fact that it did get published, I realized it's a very good example of a flawed study, where everybody see a flaw because it's evident, whereas in other studies a flaw of the same magnitude might be quite difficult to see (I could give quite a few examples from my field).
