Falsifying the 2 hour, 1 hour and 30 minutes theory before bedtime Professor Andrew Przybylski, at the University of Oxford said, "We found little clear-cut evidence that screen time decreases adolescent well-being, even if the use of digital technology occurs directly before bedtime."
For the study of Psychological Science journal the team examined information from Ireland, the US, and the UK and used a precise methodology to collect how much time a juvenile spends on screens per day, including both self-reported measures and time-use diaries.
