Scientists at the University of Oxford shed previous research on the effects of screen usage on sleep behavior. For example, a previous study has shown that 90 percent of children sleep badly due to long screens. But from this broader study, the relationship between sleep time and screen seems to be "extremely modest."
According to the study, every hour of screen time results from three to eight minutes less sleep at night. Scientists believe that this correlation is too small to arrive at grounded claims.
According to lead researcher Andrew Przybylski, parents should look at other habits around sleeping time to improve sleep behavior. "Focusing on regular bedtime routines and sleeping patterns, such as consistent walking moments, are the most successful strategies to help young people sleep, think that the screens play a significant role," said Przybylski to British media.
According to Przybylski, the problem of previous studies was that there were small groups of tests. He received his data from the National Children's Health Survey in the United States in 2016. This survey was conducted between more than 50,000 children up to 18 years old.
A follow-up study of the times in which children turn off their devices at bedtime will soon be published.
More information on screen time
Several high tech companies, including Apple, Google and Facebook, recently introduced new applications and control panel that give users a better understanding of their screen time and application usage. This should prevent the excessive use of phones and tablets.
