Studies show that children should not be forced to use smartphones or PCs for limited hours

There has been research on the adverse effects of long-term use of smartphones and tablets by children over time , and there are studies that say there are adverse effects over television, and in Taiwan a law has been enacted that parents have to limit their smartphone usage time Or something that is often regarded as a problem. For such a trend, research has also been published that 'the harmful use of digital screens is not related to the psychological well-being of young people', and it forcibly restricts the use of digital media to children. There are also researchers who deny things.

Digital Screen Time Limits and Young Children's Psychological Well-Being: Evidence From a Population-Based Study

The American Academy of Pediatrics recommends that parents should limit their exposure to digital media for children between the ages of two and five to two hours or less. However, these guidelines are based on the findings that 'active play and learning are possible instead of using media' and 'sitting posture may lead to lack of sleep', and to psychological well-being It is not an empirically-evaluated standard for the impact of this, said Andrew Psibirski of Oxford University and Netta Weinstein of Cardiff University .

Children who have been exposed to digital media for less than the time limit set by the American Academy of Pediatrics in a 2017 study had only a slight increase in activity like playing outside, but the other favorable effects were on other children It was said that it was lower than it. These differences are not important when considering factors such as household income and education level. It is also surprising that “very small positive effects” have been found, even when “touching digital media for about 7 hours”, which is much higher than what is generally considered to be healthy.

In addition, research on behavioral science has also reported that 'too much PC and smartphone watching' can not reduce the happiness of young people . Emi Oben and Psivilski, who were involved in this study, said, “The previous studies that examined the impact of social media on teens and twenties lead to false conclusions because they are based on weak correlations and inadequate methods. I claim that.

From these results, researchers say that, given the broader range of data, the impact of digital media on well-being is too small to justify policy changes, forcing digital It denies restricting the use of media.

Following these studies, Nautilus states, 'The most important thing is to make children aware and independent that we use tools rather than tools.' Children learn attention and flexibility from play, and it is unlikely that the same benefits will be impeded by digital media. He also said that it is possible to build a bad relationship with the media, even though the time to touch digital media itself is not bad, and argues that interventions should be done to protect children from that aspect.
