Change in Social Media Use and Well-being Among College Students Receiving a Two-week Exercise or Mindfulness Intervention

The investigators will be randomizing 300 college student participants with high levels of social media use into either a 1) control condition (no intervention), a 2) mindfulness meditation cognitive intervention, or 3) a social media reduction + exercise replacement intervention. Participants complete intervention activities daily for two weeks. The investigators will collect self-report and behavioral measures of social media use and related psychological constructs at three time points: baseline, immediately after the intervention period, and one-week after the intervention period (three weeks from baseline).
