Free Play, Youth Mental Health, and the Role of Cities An Opinion on Uncertainty and Opportunity

Abstract

Children and adolescents are experiencing rising rates of mental health issues, coinciding with a long-term decline in outdoor free play. Free play is a self-directed, voluntary, and inherently social activity that supports autonomy, emotional regulation, and social competence. We evolved using these innate, internal resources in relation to the environment and each other. Yet, urban environments today often provide fewer opportunities than in previous generations. This article argues that designing streets and open spaces to enhance safety, visibility, and spontaneity is a key part of restoring outdoor play, with significant potential benefits for youth mental health. Although anecdotally evident, demonstrating this in the scientific field requires proactive, mixed-method research across diverse urban contexts, alongside co-creative interventions that recognize free play without directing it. This research can advocate on the part of young people, in the face of competing uses of public space for road traffic or other use, and support development of thoughtful urban design. This, paired with iterative experimentation and collaboration, will aid cities to foster healthier developmental trajectories for current and future generations of young people.
