The intertwined relationship between physical activity and brain health

John J Ratey in his book Spark highlight the crucial link between physical activity and brain health. They contend that regular exercise is not merely advantageous for physical fitness, but vital for maintaining a healthy and high-functioning brain. This is attributed to exercise's ability to enhance the brain's "infrastructure" by strengthening existing neural connections and promoting the creation of new ones. When a person engages in physical activity, neurotransmitters like dopamine and serotonin, which are crucial for learning and mood regulation, are released in greater quantities.
