According to the National Sleep Foundation, almost all of us (95 percent, to be exact) use some form of technology in the hour before bedtime. You know that’s not good for you, but it turns out: Not all forms of pre-sleep technology are equally bad. A recent study from the University of Texas-Pan American shows that people who text, email or browse the Internet experience greater insomnia than those who refrain from the practice. But people who watch TV—everyone’s favorite pre-snooze activity—don’t experience any more sleeplessness than those who head to bed without a little taste of The Daily Show or Jay Leno. Scientists posit that the light that screens emit may not be the problem; it’s the interactivity they foster that keeps us awake.
