Memes that are too meirl for /c/meirl.

Rules:

  1. Respect the community. If you're not into self-deprecating/dark/suicidal humor then this place isn't for you. Kindly just block and move on. This is just how some of us cope.

  2. Respect one another.

  3. All titles must begin with 2meirl4meirl. This is for multiple reasons. One is just so you can be lazy with titles but another is so people who aren't into this kind of humor can avoid it.

  4. Otherwise just the general no bigotry, no dickishness, no spam, no malice, etc stuff.

Sidebar will be updated when I feel like and considering I'm Sadboi extraordinaire we'll see when that will be.

If it helps, the science of phone screens disrupting sleep patterns is sketchy at best.

To test the theory, BYU psychology professor Chad Jensen and researchers from the Cincinnati Children’s Hospital Medical Center compared the sleep outcomes of individuals in three categories: those who used their phone at night with the Night Shift function turned on, those who used their phone at night without Night Shift and those who did not use a smartphone before bed at all.

“In the whole sample, there were no differences across the three groups,” Jensen said. “Night Shift is not superior to using your phone without Night Shift or even using no phone at all.”

Actually they found higher sleep quality in some groups.

The article also doesn't mention how long the study was and only looked at 18-24 years old.

The main issue with light exposure are long term effects, such as increased rush of hormone-depebdant cancers.

We don't have a lot of long term study, but we know melatonin production is affected.

For the record, I did my PhD on light pollution, and while not a health expert, I have assisted to multiple talks at scientific conferences on the subject.

Can you talk more about melatonin, hormone dependent cancers, and light exposure? Also, what about shift work and rotating schedules?

[–] surewhynotlem@lemmy.world 4 points 2 months ago

I use my phone 16 hours a day, and sleep wonderfully the other 8 (when my kids let me, which is never)

Oblig. "My anecdote is not evidence"

Hah, jokes on you Science, my circadian rhythm has been fucked for my entire life and I'm also old enough to have had a childhood where cell phones didn't even have screens on them.

Just because I know what the science says doesn't mean the science lines up with how I choose to ignore the hellscape we live in.

[–] Aeri@lemmy.world 13 points 2 months ago

Well there's a difference between refusing to believe the science and completely understanding the science and just continuing as you were anyway

[–] zkfcfbzr@lemmy.world 11 points 2 months ago

Bold to assume I care about preserving my circadian rhythm

There isn't a single hour of the day I haven't both fallen asleep during and woken up during at least once in the last three months

Most people who say "I believe science" don't know anything about the scientific process, how it works or why. They use "science" as a cheap substitute for "god" when they are atheists / agnostics but still feel the need to "believe". Science doesn't need believing.

Do you ever think about how if we actually cared enough to make a phone that was just as easy for a blind person to use, it would also be a phone that any person who isn’t blind could use just before bed without any of these other issues?

[–] GluWu@lemm.ee 4 points 2 months ago

My circadian rhythm is abstract jazz. I've slept less than 5 hours in the last 72.

[–] Iheartcheese@lemmy.world 4 points 2 months ago* (last edited 2 months ago)

Normal sleeping patterns are for the weak of heart.

Edit- it's 3:12 a.m. and I have two screens

[–] ramble81@lemm.ee 3 points 2 months ago

I mean I understand the science and believe it’s accurate, I just don’t care. Kind of like alcohol.

I don't keep anything that connects to the internet by my bed

Thank you! Sorry for the half-second removal, I am barely conscious lol

[–] LadyButterfly@lazysoci.al 1 points 2 months ago

Haha you're good

You can just take ur melatonin from a bottle. Store bought is fine too ?!

[–] Zexks@lemmy.world 1 points 2 months ago

I've had a shitty rhythm since long before phones.

Science has always been like this: "Don't do [insert any thing I regularly do] or you are fucked".
