Capturing this fact, in their research, two scientists Amy Orben and Andrew Przybylski have asked participants to fully and clearly record their screen time, instead of reporting data. in a "reminiscent" way, influencing the final outcome of the study.

Research by Amy Orben and Andrew Przybylski titled: 'Screens, Teens, and Psychological Well-Being: Evidence From Three Time-Use-Diary Studies' (temporarily translated: Screen, Youth and Psychological Health: Degree According to three names, the researchers from Oxford used the data collected by three other research projects.

"We have found very little evidence of a significant negative relationship between the time of using electronic devices with screens (measured throughout the day), or especially during the period before going. sleep and health status of adolescents. '

"Thirdly, this is also one of the first studies to consider whether the use of digital electronic devices just before bedtime has caused negative effects as well as disadvantages. For a long time, it seems that it is safe to say that using a digital screen right before bed can be more harmful to young people than they do. Spread out throughout the day To clarify this concept, we conducted surveys and collected specific recorded data from volunteers and analyzed and synthesized the results quite confusing. : Some argue that there are negative images, while others see this as positive or not causing any Therefore, our study has shown that using a computer monitor, a phone when sleeping may not be harmful to psychological health, although this is a common concept.
