The impact of exercise on mental health is a complex and multifaceted topic that has garnered significant attention in recent years. This comprehensive review aims to provide an in-depth examination of the relationship between physical activity and mental well-being, synthesizing the latest research findings and practical implications. Exercise has been consistently shown to have a profound impact on mental health, with benefits extending to mood regulation, stress management, anxiety reduction, and depression alleviation. The release of endorphins, also known as "feel-good" hormones, during physical activity is a key mechanism underlying these effects. Additionally, exercise has been found to enhance cognitive function, promote neurogenesis, and improve self-esteem, all of which contribute to overall mental well-being. The review also explores the role of exercise in motivation, highlighting the importance of finding enjoyable activities and developing a sustainable routine. Furthermore, the integration of exercise with traditional therapies and medications is discussed, as well as the significance of mindfulness and support in facilitating positive mental health outcomes. This abstract provides a comprehensive overview of the impact of exercise on mental health, emphasizing the importance of physical activity in maintaining and improving mental well-being.
