On the bright side, a morning shot of screen time could be used as light therapy for seasonal affective disorder and other light-based problems. Figueiro hopes manufacturers will get creative with tomorrow's tablets, making them more circadian friendly, perhaps even switching to white text on a black screen at night to minimize the light dose. Until then, do your sleep schedule a favor and turn down the brightness of your glowing screens before bedor switch back to good old-fashioned books.

(49,999 posts)My monitor is regularly calibrated for accurate color and brightness for my work. If I mess with that, I could have some irritated clients!

The monitor is bright during the day, so there's no difference. It has really helped me at night. I'm actually sleeping deeper and dreaming more.

(18,312 posts)just a few weeks ago about sleep, and they made the comment that it wasn't just the light, it was the light frequency that was the culprit in disrupting circadian rhythms, especially for overnight-shift-workers like me. I sleep all day, work at night and am surrounded by bright florescent lights which I think are blue wave -length, and then on the drive home I see the blue morning sky which is another blue wavelength, when our circadian rhythm is programmed that blue wavelength = wake up time, and red wavelength (the setting sun, fire, etc) signals us to go to bed.
