Blue light.
how is that harmful? ambient light is blue most of the day
It's one of the markers that your brain uses to control its circadian rhythms. During half of your 24 hour cycle its fine. Our devices push that balance too far though, contributing to stress and insomnia by disrupting that regulatory mechanism.
Wouldn't be too different from living in the artic circle during the summertime, except without blackout shades and we're doing it to ourselves with tvs, computers and mobile devices.
RIP everyone who doesn't live exactly on the ecliptic.
The amount of time which the sun shines has very little to do with half of 24 hours most of the year where I live.
Half was a rhetorical estimate to attempt to communicate a basic idea, not an attempt to use an accurate academic term. Look it up if you want to know more, quit arguing with me. What I am describing is not new or cutting edge. We have oodles of data you can look at.
Mmh i can see that yeah that can be a bit of a stressor, but idk.. it's already known to be "less than ideal", blue light filters are super common and the body is pretty good at regulating and adjusting sleep.
Buuut i guess that's what we thought about other issues too.
Is coffee dangerous because drinking it at 11pm each night keeps you awake too? I think that's overstating your case, although I think there is a minor benefit to limiting blue light.
personally, I have all the lights set to turn red an hour after sunset and it has had a much larger effect than limiting screen time at bedtime, which is what most people seem to focus on.
Depends how sensitive you are to caffeine. I strongly suspect sensitivity to blue light is similarly varied between individuals. I am not a doctor, however, and I honestly don't give enough fucks to try to convince you.
Only when you're trying to get to sleep
Not exclusively, the body's systems are far more complex and interconnected than that. It's really just the need to have some kind of nighttime for your overall well-being. It's what we evolved around.
