Physical education (PE) is a vital component of holistic education, yet its relevance to academic performance and mental health is often underestimated. This study explores the correlation between regular physical education and improvements in academic performance and psychological well-being among school students aged 10–16 years. Using both quantitative and qualitative methods, findings indicate that regular physical activity through PE sessions enhances cognitive function, reduces stress, improves mood, and fosters better academic engagement. The results underline the need for integrating quality PE programs into the school curriculum to foster academic excellence and mental health resilience.
