Study: Light-Emitting Screens Before Bedtime Disrupt Sleep

Posted by Soulskill on from the why-you're-tired-all-the-time dept.

jfruh writes: Tablets and e-readers are more convenient in many ways than paper books, but many people have complained that the physical experience of using them isn't as good. And now we have some specific quantification of this fact: a study has shown that people who read text on a tablet before bed don't sleep as well as those who read a traditional book (abstract).

    How can I believe you when you tell me what I don't want to hear?

    I understand what you are getting at. I'll use an iPad Retina or laptop during the day to check technical books, reference manuals and other documentation.

    However when reading at night its generally a more traditional book (history, sci fi, etc) on a Kindle PaperWhite, in my opinion, its equivalent to a paper book but more convenient. I feel it is a better experience even when compared to the lightest color tablets. Certainly it will vary from one technical field to another but I've had surprisingly good results when reading programming and software development books on the PaperWhite, not as good as a higher resolution color tablet but better than I expected and acceptable with respect to the illustrations and diagrams and such. Then again I haven't tried something like the latest edition of Foley and van Dam (a computer graphics text).

    I see the refresh you speak of but its less than turning a paper page of a real book. As for the time you believe you are saving, maybe the faster refresh of a color tablet is not a win once you consider the sleep disruption and also the lowered productivity that results?
