"We know that night-time exposure to blue light keeps people up late. We believe that f.lux adjusts colors in a way that greatly reduces the stimulating effects of blue light at night."
I plan on blacking out my bedroom, so I can sleep in the daytime, if I have to, and not mess up my hormones...not so easy to get it 100% and still have it look nice.
Also want to install an automatic roller blind that simulates sunrise :)
