A recent peer-reviewed study has revealed a concerning connection between screen time and the emergence of manic symptoms in U.S. preteens. Conducted by researchers at the University of Toronto and the University of California, San Francisco, the study analyzed data from 9,243 early adolescents aged 10 to 11 years as part of the nationwide Adolescent Brain Cognitive Development study.

The findings indicate that preteens who spend excessive hours on social media, video games, texting, and videos are more likely to develop symptoms including inflated self-esteem, decreased need for sleep, distractibility, rapid speech, racing thoughts, and impulsivity two years later.

Lead author Jason Nagata, MD, explained that adolescence is a vulnerable period for the onset of bipolar-spectrum disorders, making early detection and intervention essential. Co-author Kyle Ganson, PhD, noted that screen addictions and irregular sleep patterns may further exacerbate these symptoms.

Although screens offer educational and social benefits, the study emphasizes potential risks when usage is unmonitored. Parents are encouraged to establish healthy digital habits and implement screen-free times, especially before bedtime, to protect their children’s mental well-being.

This research adds to growing evidence linking excessive screen use with long-term mental health challenges, prompting families and educators to reconsider screen exposure. Burble Creativity’s Story Tent is a great alternative to screen time, offering an immersive environment that frees the imagination.
