Wasn’t it confirmed recently to be total nonsense and nothing to do with circadian rhythms? Compared to the sun a phone puts out very little light and the circadian rhythm only respond to slow changes in light, not on and off in a short time.
It’s more about your phone keeping your mind active instead of relaxing and going to sleep. But if you already can’t sleep because your mind is churning on something, a bit of distraction might actually help. It’s very personal and not a clear cut rule on who has trouble sleeping from phone use or when to put down the phone.
So it isn’t like using your phone before sleeping will never have an effect on how well you get to sleep. But it has nothing to do with blue light or circadian rhythms.
I think there are multiple, I read an article recently where it was stated by an expert. But checking back now they don’t link any sources except the name of the expert, which seems to be a respected expert in the field, but that means nothing in the end.
This is one of the papers I could find within 2 mins, but I think there have been multiple papers on this.
There has also been a lot of criticism on the original study that said blue light from phones was the issue, so there are probably a lot of response papers to be found about that.
tbh almost every time I see a system settings panel or a program that lets you reduce blue light on a schedule, it’s always accompanied with a description that sounds like “reducing blue light may help you sleep better”. I don’t think there are many people touting it as some sort of scientific neurological thing, it’s just that many users have a personal preference for reduced blue light at nighttime, and the developers want to accommodate that preference. Not everything has to be backed up by scientific research, sometimes people just like things.
Some years ago I started reading in bed before going to sleep. Pretty much always, I’m reading a book on my tablet. Now I find that the habit/routine of it helps me go to sleep.
The exception is when the book is so engrossing that I have a hard time putting it down and end up staying awake longer than I should.
Probably also varies depending on the type of content people are checking while on their phone. I can stay awake forever playing Balatro while reading usually knocks me out real quick.
The best thing I found to help me sleep well was getting my adhd diagnosis and meds. It’s so much easier to sleep when the voices in your head shut the fuck up

Couldn’t find the study confirming this. Can you link to it, please?

The whole “blue light” thing is the new “wifi is going to give you cancer”.

I think what was proven wrong was the significance of the color of light. The original study had people using iPads at like maximum brightness.
The migraine afterwards would probably keep me awake, too.

Just one more run…
