How does exercise impact mental health in the long term?

Exercise has a profound impact on mental health in the long term, primarily by decreasing overall stress levels. Engaging in regular physical activity stimulates the production of endorphins, which are known as "feel-good" hormones. These endorphins help to enhance mood and promote a sense of well-being, effectively countering feelings of stress and anxiety.

Furthermore, exercise can improve sleep quality, boost self-esteem, and provide opportunities for social interaction, all of which are beneficial for mental health. Over time, these cumulative effects contribute to a reduction in anxiety and depressive symptoms, making exercise a powerful tool for maintaining mental wellness.

In contrast, the other options presented do not align with the established benefits of physical activity on mental health. Increased anxiety, reduced motivation, and feelings of fatigue are generally associated with a sedentary lifestyle or insufficient coping strategies rather than the regular practice of exercise.
