Scientists at the University of Oxford have discovered previous research on the effects of screen use on sleep behavior. For example, a previous study showed that 90% of children are sleeping abnormally because they have watched too much time on screens. But from this larger study, the relationship between sleep and time spent on the screen appears to be "extremely modest."
According to the study, every hour of screening results in three to eight minutes less sleep at night. Scientists find this correlation too small to reach substantiated claims.
Adjust your habits
According to principal investigator Andrew Przybylski, parents should look at other habits around bedtime to improve sleep behavior. "Focusing on bed routines and regular sleep patterns such as consistent periods of time are more successful strategies to help young people sleep than to think that screens themselves play a significant role," Przybylski told the British press .
According to Przybylski, the problem with previous studies was that there are too small test groups. He obtained his data from the National Children's Health Survey in the United States in 2016. This research was made among more than 50,000 children under the age of 18.
A subsequent study on the periods when children close their devices before bedtime will be published shortly.
More understanding during the screen
Several major technology companies, including Apple, Google and Facebook, have recently introduced new applications and new dashboards that give users a better understanding of on-screen time and application usage. This should prevent excessive use of phones and tablets.
