Our displays are made for daylight working. This causes a problem: When it is at night, they will keep us awake more then they should.
Researches have proven that cold colors will keep us awake, while warm colors are making us sleepy. Just think about the color of your light. Isn’t it a bit yellow?
If you let f.lux automatically adapt the color of your monitor when the sun is set, it will let you sleep better :)
Just give it a try! You can get it for free for Windows, Mac, Linux, iPhone and iPad, at https://justgetflux.com/
Not convinced yet? Here is a video which shows f.lux in action:
