A recent Finnish study suggests that limiting screen time and promoting physical activity from childhood may help safeguard mental health in adolescence. The findings are particularly significant given that mental health problems affect up to 30% of young people and pose a growing societal challenge.
The study, conducted by the Faculty of Sport and Health Sciences at the University of Jyväskylä and the Institute of Biomedicine at the University of Eastern Finland, followed 187 adolescents over an eight-year period. Researchers found that children who spent more time on screens -especially mobile devices – were more likely to experience higher levels of stress and depressive symptoms in adolescence.
Conversely, higher levels of physical activity and participation in organized sports were associated with lower stress and fewer depressive symptoms. However, the link between physical activity and depressive symptoms was weaker than that of screen time and depressive symptoms. Adolescents with both high screen time and low physical activity had the highest levels of stress and depressive symptoms.
A recent study highlights the importance of limiting screen time and promoting physical activity to protect children’s mental health. Researchers found that excessive screen exposure, particularly on social media and video games, is linked to increased anxiety, depression, and sleep disturbances in children. Conversely, engaging in regular physical activity helps improve mood, reduce stress, and support cognitive development.
The findings emphasize that children who balance screen time with outdoor play and exercise experience better emotional well-being and social interactions. Parents and caregivers play a critical role in setting boundaries around digital device usage and encouraging active lifestyles. By creating structured routines that prioritize movement and real-world connections, families can help build resilience and positive mental health habits in children.
