What is the relationship between physical activity and mental health?

Regular exercise can significantly reduce symptoms of anxiety and depression, highlighting the positive relationship between physical activity and mental health. Engaging in physical activity triggers the release of endorphins and other chemicals in the brain, which can improve mood and create a sense of well-being. This biochemical response can alleviate feelings of anxiety and melancholy, making exercise an effective tool in managing these mental health challenges. Additionally, physical activity can provide a sense of accomplishment and routine, further enhancing mental resilience.

In contrast, the other options do not align with the well-established understanding of physical activity's benefits for mental health. The idea that physical activity has no effect on mental health contradicts numerous studies that show its positive outcomes. Similarly, the notion that exercise increases stress levels overlooks the stress-relief benefits associated with regular physical activity. Finally, limiting the benefits of physical activity to only physical health fails to recognize the integrated nature of mental and physical well-being, as both aspects are closely linked.
