The Impact of Physical Activity on Mental Health

Physical activity has emerged as a powerful tool for improving mental health, as evidenced by a thorough review published in the British Journal of Sports Medicine. Encompassing 97 reviews, 1039 trials, and over 128,000 participants, the study highlights the profound benefits of exercise in alleviating symptoms of depression, anxiety, and psychological distress.

Key Findings:

• Exercise interventions lasting 12 weeks or shorter were most effective in reducing mental health symptoms, underscoring the rapid impact of physical activity.
• Significant improvements were noted across various groups, including individuals with depression, pregnant and postpartum women, and those with conditions like HIV or kidney disease.
• The World Health Organization reports that approximately 970 million people globally live with a mental disorder, with associated economic costs projected to reach $6 trillion by 2030.

Lead researcher Dr. Ben Singh emphasizes the urgent need to prioritize physical activity as a primary treatment for managing mental health conditions:

• Despite its proven benefits, physical activity is underutilized in mental health treatment protocols.
• Higher intensity exercises showed greater improvements in depression and anxiety, while various forms of exercise such as aerobic activities (e.g., walking), resistance training, Pilates, and yoga were all beneficial.
• Even minimal amounts of exercise can significantly enhance mental well-being, making it accessible for all individuals.

Senior researcher Prof. Carol Maher highlights that this comprehensive review provides clinicians with a clear understanding of how different types and durations of physical activity can effectively support mental health across adult populations.

This study underscores the critical role of physical activity in mental health management and advocates for its widespread adoption as a foundational approach to improving well-being globally.
