The Cost of Unstructured Indoor Hours
Adolescents aged 13–18 spend an average of seven hours and 22 minutes on screens for entertainment each day, according to the American Psychological Association Stress in America 2021 report. Yet studies from PLOS ONE show that every extra sedentary hour above four hours correlates with lower mood scores. A household stocked with quick indoor activities can break that cycle without another costly outing.
