Serotonin plays an essential role in mental health by regulating mood, anxiety, and feelings of well-being. Often referred to as the "feel-good" neurotransmitter, adequate serotonin levels contribute to a positive emotional state, which is crucial for managing stress. A lack of serotonin can lead to mood disorders such as depression and anxiety. Regular exercise is known to boost serotonin levels, promoting mental clarity and emotional stability, demonstrating a strong link between physical activity and improved mental health outcomes.
