In all honesty, I’ve found it healthier to have fixed color temperature in different rooms, and change what room I’m in throughout the day. I’m only in my bedroom when warm lighting makes sense, I’m only in my office when cool lighting makes sense. That helps establish other healthy habits than just sleep, and keeping the bedroom dedicated to sex and sleep is a good practice anyway to combat insomnia.

That sounds great, but many people (especially those living in cities) don't have that many rooms in their home, so other solutions are needed.

In the past I have put up a curtain around my bed (although originally for other reasons.) Like a homemade canopy bed!

> although originally for other reasons

I dont want to get into too much speculation, but the answer obiviously is building a fort?

> keeping the bedroom dedicated to sex and sleep

Yes. No computer of any sort, the alarm clock's only advanced technology is radio-synchronization and I don't even let a book enter the bedroom - that is for the living-room couch. Does wonder for sanctuarizing the late evening !

So you don't charge your phone in your bedroom?

If they won't even let a book in, the phone is definitely in exile - between eye strain, work emails, and the entire internet, phones are pretty terrible sleep hygiene offenders.

I've heard this often enough that I'd repeat it as general advice, but personally I find that reading on my phone until it's falling out of my hand expedites falling asleep better than anything else, as long as it's not something that compels me to reply / take notes / data flow into the phone (a "two steps back" event). A long-ish article, not doomscrolling.

And definitely use f.lux or equivalent, which is built in these days (at least the phones I've had recently).

Me too. And my phone automatically goes on do-not-disturb prior to bedtime, so no concern of seeing a notification that gets my brain going.

The other nice thing about reading on my phone rather than reading a physical book before bed as I used to do is that I don't need a light. I have the phone brightness turned way down, and obviously use light text on black background. Helps with falling asleep and doesn't disturb my wife if she's going to sleep before me.

I guess some people worry about being unreachable by family in an emergency

That might be a valid corner case, but most folks in this category are simply mildly addicted to screens the kick the usage gives them.

Drug addicts have been vilified for many decades yet most western population falls into some addict category, be it screens, various fetishes, sugary products/chocolate, tobacco products, alcohol, prescription drugs and so on just from legal state-approved sphere.

Just look at average teens these days. Try taking them their gadgets if you want to see some proper hate in their eyes.

I'm shocked that you didn't mention caffeine -- caffeine addiction, in my opinion, is rampant, especially among office workers.

No judgment, either; I struggle without coffee.

I think most modern phones let you select a list of people that will be able to reach you in an emergency.

Mine also has a setting to allow the phone if people call twice within 3 minutes or something.

I used to oversleep but it's completely fixed by leaving my phone in the living room so I must get out of the bed and shut the alarm off.

I do this, but also have different lighting options in certain rooms, like the office.

In my office, the ceiling light is a daylight bulb, but i also have a couple lamps with warmer lights. During the day, I run the ceiling light, and after sunset, turn the ceiling light off and turn the lamps on.

Perhaps a bit Luddite, but less fuss and cost.

Did you try punching in your folk wisdom into clinicaltrials.gov?

Here's "blue light sleep":

https://clinicaltrials.gov/ct2/results?term=blue+light+sleep...

Do you see any affect of blue light on sleep? Or do you see conclusive evidence that blue light does not affect sleep?

This reply comes off as needlessly condescending. If you have a point to make, make it, don't assign homework and ask leading questions.

I was curious where you were coming from, since I thought I had read research on this and my own experience is that changing light temperature is incredibly helpful.

The first one I clicked on showed blue-blocking lenses measurably improve sleep. I don't find the need to confirm more research at this point, given that it clearly helps me.

Blue blocking never helped me but dimming and warming the lights close to bedtime makes me sleep so much better
