UC Davis Study Finds Sleep Beats Screen Time for Teen Academic and Social Success

A new study by UC Davis Health examined how four lifestyle factors—sleep quality, screen time, physical activity and diet—affect the relationship between mental‑health symptoms and academic and social functioning in adolescents aged 10 to 13. Using data from the Adolescent Brain Cognitive Development (ABCD) study, researchers found that sleep quality was the strongest factor linked to better grades and fewer social problems, explaining 36.3 % of the anxiety‑related decline, 18.5 % of the depression‑related decline and 8.3 % of the psychotic‑like symptom‑related decline. Screen time was the second‑strongest factor, accounting for roughly 5‑6 % of these associations. The effect of sleep was especially pronounced for teens already experiencing anxiety or depression. “This finding surprised us,” said first author Jason Smucny, noting that sleep stood out clearly above other lifestyle factors. The study was published in Psychological Medicine.
