College leaders are treating unhealthy phone habits as a campus‑level health issue and layering new responses on top of traditional counseling services. Administrators report students spend five or more hours daily on nonacademic phone use, and institutions are testing interventions—time‑blocking, device policies, and attention management coaching—to protect mental health and academic performance. At the same time, young people increasingly use generative AI for emotional support and study help. New research identifies distinct youth personas—ranging from skeptical users to emotionally entangled 'superusers'—and finds that those turning to AI for mental‑health support often face barriers to professional care. Why it matters: colleges must integrate digital‑wellness strategies and supervised AI literacy into student‑support services to address emerging risks and unmet needs.
