Neurotransmitters are chemical messengers that transmit signals in the brain and play a significant role in regulating various bodily functions, including the response to physical activity. Exercise stimulates the release of neurotransmitters like endorphins, dopamine, and serotonin. These not only improve mood but also enhance mental clarity and focus. Engaging in regular physical activity can contribute to the balance of these chemicals, ultimately leading to better mental health and emotional well-being, which underscores the strong link between movement and cognitive function.
