Teen screen time and mental health: red flags, risks, and what parents can do

Experts warn that changes in teen behavior—such as erratic sleep, poor focus, and irritability—may signal “digital distress” tied to excessive phone and social media use. Psychiatrist Dr. Jennifer Zumarraga highlights that constant screen time can lead to anxiety, depression, self-harm, and strained relationships, while also interfering with academics and family life. She stresses the importance of parents setting limits and modeling healthy screen habits, noting that a “digital diet” is difficult but requires family-wide commitment.
