Matt introduces "doomscrolling," linking compulsive online consumption to worsened sleep and mental health. He tracks social media's rise (1997-2016), noting increased addiction. By 2016, 82% of 12th graders spent six hours daily online, often at sleep's expense. Matt also highlights heightened psychological distress in adolescent girls due to comparison-focused platforms.

Noting that "doomscrolling" is tied to FOMO, addiction, and distress, he describes a bidirectional loop: poor sleep drives doomscrolling, intensifying depression, further degrading sleep. Challenging the blue light myth, Matt shows minimal sleep onset delay. And identifies cognitive/emotional arousal and the FOMO-rumination-procrastination cycle as true disruptors. He concludes with practical interventions: usage caps, phone-free bedrooms, and consistent cutoff times.
