Ready for Bed

Swiss researchers say that screen time before bed makes it hard to sleep. It's not just that reading and thinking gets your mind wound up (though I am sure that's part of it.) Exposing yourself to light messes with the body's melatonin production. Having a low level of melatonin keeps your body in daytime mode and keeps you from being ready to sleep.

The new research shows that light from laptop screens, cellphones or tablets causes more disruption of melatonin than other lights. I don't see any mention of what the control lighting is: incandescent? CFL? LED? television?

Teenagers, already susceptible to confused sleep cycles, are especially affected.

My first thought: profitable app opportunity. Second thought: the app world is way ahead of me. From the comments:

"As for apps that filter blue light, I would recommend f.lux for OSX, iOS (iPhone/iPad) , Windows, and Linux, and Twilight or Lux for Android. I have tried others, but those are the best." -Andy
