Brief Summary   This observational study is designed to investigate the relationships between screen time, physical activity levels, and cognitive parameters such as attention span and reaction time among college students. By examining these variables, the study aims to identify patterns and correlations that can inform interventions to mitigate the adverse effects of excessive screen time. Additionally, it seeks to explore whether physical activity serves as a protective or compensatory factor against the cognitive risks posed by digital overexposure. This dual focus is critical for developing holistic strategies that address the multifaceted challenges faced by today’s students. The significance of this study lies in its potential to contribute to a deeper understanding of the behavioural and lifestyle factors influencing cognitive functions. In an increasingly digitalized world, educational institutions, parents, and health professionals are grappling with the task of balancing technology use with the promotion of healthy habits. The findings from this research can serve as a valuable resource for designing evidence-based guidelines and interventions that prioritize students’ cognitive and physical well-being. For instance, educators can incorporate screen-time management strategies into their curricula, while parents can encourage active play and outdoor activities to counterbalance sedentary behaviours. Health professionals, on the other hand, can leverage these insights to advocate for policy changes that support healthier lifestyle choices among young people.
