Research + Evidence

Smartphone and other digital media use are exposing young people to risks and replacing experiences that help youth achieve their full potential. SYNC is a movement designed to shift local norms from continuous scrolling to intentional technology use, creating connections rooted in belonging.

  • Owning a smartphone before age 13 is linked to higher risk of depression, obesity, and poor sleep.[1]
  • Nearly half of teens (48%) say social media platforms have a mostly negative effect on people their age.Teen girls are more likely than boys to say social media harms their mental health (25% vs. 14%), confidence (20% vs. 10%), and sleep (50% vs. 40%).[2]
  • Two or more hours of daily screen use is linked to depression,[3] difficulties with peer interactions,[4] worse academic outcomes,[5],[6] impaired sleep quality,[7] and worse relationships with parents.[8]
  • Parent media use is a strong predictor of child media use.[9]
