This is purely an enorsdment of an app I use, it is unsolicited and unpaid.
I have no idea how long I have been using f.lux and I wish I could remember where I read about it so I could thank that person. In fact f.lux works so well you almost forget that it is there.
What is f.lux? From their website-
Ever notice how people texting at night have that eerie blue glow?
Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen?
During the day, computer screens look good—they're designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn't be looking at the sun.
f.lux fixes this: it makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.
It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better.
How do I use f.lux? Download it and then-
f.lux makes your computer screen look like the room you're in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.
Tell f.lux what kind of lighting you have, and where you live. Then forget about it. f.lux will do the rest, automatically.
Why use f.lux? First off almost every list of sleep tips I see talks about readucing screen time at least an hour prior to bed. Why?
According to the New York Times–
Increasingly, researchers are finding that artificial light from some devices at night may tinker with brain chemicals that promote sleep. Researchers at Rensselaer Polytechnic Institute showed that exposure to light from computer tablets significantly lowered levels of the hormone melatonin, which regulates our internal clocks and plays a role in the sleep cycle.
f.lux adjusts the colors of your screen in a way that greatly reduces the stimulating effects of blue light at night.
There is a ton more research the creators of the app have posted here–
