The first and third apply to TV, radio, podcasts, or possibly even reading. The second isn’t a guarantee (not conclusive for everyone) and can be solved with technology.
The real science here is practicing good sleep hygiene. Your phone is one of many things that can fuck with that; it’s only a small part of it.
You're right. Light with lots of blue in it, like the dawn, wakes us up.
Want to hear a dumb story? Been patting myself on the back for a couple of years because I set the e-reader on my tablet to black with dark orange letters.
"That blue light won't get me!"
I just now realized that it still casts a blue light on the ceiling when I lay it down.
Eh, even in "the real world" we still encounter blue wave lengths in the evening. I think it is a matter or reduction (aka not shoving a largely blue light source in your face) than elimination.
Some years ago, I had to get up very early for a job. So, to make it easier on me, I bought/built some programmable LED lights and set them to gradually shift from dark red to bright blue-white.
Fast forward some years, and I can comfortably ignore bright sunlight and 50W of white LEDs in my face. I don't even bother to put down the shutters any more. I wake up, semi-consciously acknowledge that it is morning, turn around and continue sleeping.
Best I can do is enabling Night Light
+Extra dim
I have it always on, I'm so used to it I don't even notice
Yeah, until I go outside and think my phone is dead
Oh, I believe it. I just don't want to stop.
I believe science. But that doesn't stop me from not listening to it
Bruh I sleep with phone like it's a stuffed animal.
Oh God, the truth in this hurts.
Source please, I'm very guilty of this and would love to read up on it.

So before is bad, but after?

Before bed I've heard, but right after waking? I thought light was good then for getting you more alert?

Story time!

Science: Please stop using the word believe, it's making me nervous.
Look, I believe that dancing naked in the rain increases the chances of getting hit by lightning, but I'm still gonna do it
I don’t appreciate the targeted attack, this is literally me right now.
Science isn't really meant for doggish belief; no need for a flock
No worries, I just use my TV instead.
Just blame it on your genetics. Then you can use your phone whenever you want because it's your genetics fault.
ISILDUR!
