Why do sleep experts recommend to stop using screens one hour before bed, why just one hour before bed?
In: Biology
At least one hour. Screens give off blue light which fools your system I to thinking it’s still daytime.
By turning off the bluelight from screens, your body takes queues from the environment that’s it’s evening and will start to release melatonin which makes you sleepy.
You can use an app called flux, which reduces the bluelight of your screen, so you still release melatonin and get sleepy.
