Do you go to bed with a tablet or e-reader? Researchers think that the artificial light that both of these produce might be the reason that some of us can't sleep.
If you'll remember, a clinical psychologist already called for everyone to keep tablets out of your bedtime routine over the summer. The latest study making similar claims had only 12 participants.
While the voice of one clinical psychologist definitely isn't enough to make me ban tablets and e-readers from my bedroom, I'm not sure that this study is either.
The study was published in the National Academy of Sciences, and I'm holding off on the verdict until more facts come to light.
The study was lead by Anne-Marie Chang of the Brigham and Women's Hospital. The study tested the effects of reading paper books before bed against e-books. Chang explained the procedure behind the results of her study:
'Participants reading an LE-eBook took longer to fall asleep and had reduced evening sleepiness, reduced melatonin secretion, later timing of their circadian clock and reduced next-morning alertness than when reading a printed book.'
With such a small sample size, it's almost impossible to rule out any extraneous variables that might have changed the results.
Contrary to some of this study's claims, these gadgets might actually improve your sleep.
