Mental health and physical health intersect in fitness by contributing to a holistic sense of well-being. Regular exercise releases neurotransmitters, like serotonin and endorphins, which enhance mood and reduce symptoms of anxiety and depression. Conversely, poor physical health can negatively impact mental health, leading to feelings of inadequacy or stress. Therefore, fitness serves as a vital tool for enhancing both mental and physical well-being. Engaging in physical activity creates a positive feedback loop, where improved mental health encourages more consistent exercise routines.
