A new study that involved more than a million American high school students, found that adolescents who spent more time on screens (e.g., social media, the Internet, texting, gaming) and less time on non-screen activities, experienced lower psychological well-being. Adolescents who spend little time on electronic communication were the happiest. In short, technology makes teens unhappy, but why? What is it about technology that makes people unhappy? Psychologist, Dr. Ellen Hendriksen, puts forward five ways technology exacerbates anxiety in people.
