Exercise significantly influences mood-regulating neurotransmitters such as serotonin, dopamine, and endorphins. Physical activity boosts the production of these chemicals, which play crucial roles in improving mood and relieving symptoms of depression and anxiety. Regular exercise also promotes better sleep patterns, which is essential for maintaining emotional well-being. Moreover, increased blood flow to the brain during exercise can create a sense of euphoria, often referred to as the "runner's high." Overall, exercise acts as a natural mood enhancer.
