Sleeping problems is a pretty extreme case. If the tablet or laptop pushes your sleep time back to midnight from 10 PM, that could be a large and significant effect even if one doesn't consider it 'a problem'. (In some groups, this might be a problem, and the paper specifically mentions them: adolescents already have a sleep schedule that has been pushed back by puberty, love their gadgets, and have hard and early wake-up times. The result: highschoolers spend the first few classes half-asleep.) |
