The research is out and the news for late-night computer time is not good: We know you probably already know that the blue light emitted by screens mimics the brightness of the sun and causes the brain to stop producing melatonin (and hence makes it much harder to fall and stay asleep).
But simply knowing that checking Facebook before you go to bed at night may not be enough to actually get you to stop looking. And for already sleep-deprived teens who have to stay up late for homework, the blue-light issue is a critical one.
So here’s a resource that may be worth using: f.lux is a program that makes the color of your computer’s display adapt to the time of day, warm at night and like sunlight during the day. This program can be installed on computers, iPads, and iPhones, and has been shown to dramatically reduce blue light’s impact on melatonin production. When the sun sets, f.lux makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again. Check out the free download here.
