Reducing blue light exposure from screens at night helps protect circadian rhythms and signals to the body that it is time to sleep.

“another thing is of course relax. I mean, don't work right up until the time you're going to bed. Take some time to do something relaxing.”

“no blue light after sunset tonight”

“Avoid blue light before bed - an hour or two before bed, try to avoid blue light. That means off screens (or eliminate blue light from your screens, there are apps and settings to do this on computer and mobile devices). Instead, turn on red and amber lights. Light can significantly affect your readiness to fall asleep.”

“Limiting blue light at night is so important for optimal circadian rhythm and sleep…”

“I take the blue light and the brightness off my phone to protect my circadian rhythm”

“I think this is helpful at night as the Sun is setting as blue light is leaving your environment I put a bunch of red lights around my house because I want to protect my circadian rhythms I want my body to know that it's time to go to sleep and I don't want to be looking at a phone that is projecting a bunch of blue light into my eyes”

“try to help the Circadian rhythm get kind of sorted I try not to have blue light after dark I avoid looking at my computer and my phone or I put them on the red light settings as much as I can in the evening and before I go to sleep I try to calm down and not look at devices and not not stimulate my brain and stuff”

“I think this is helpful at night as the sun is setting as blue light is leaving your environment. I put a bunch of red lights around my house cuz I want to protect my circadian rhythms. I want my body to know that it's time to go to sleep. I don't want to be looking at a phone that is projecting a bunch of blue light into my eyes.”

“Yeah, I would say three to four hours is the time to start thinking about your light saturation exposure, certainly in the last hour before bed.”
