A new study published in The Journal of Physiology has shed light on the long-debated question of how physical exercise enhances cognitive performance. The study reveals that dopamine, a neurotransmitter and hormone often associated with pleasure and motivation, is a key player in this process. Notably, the research demonstrates that dopamine levels increase during exercise, correlating with faster reaction times, thus providing a clearer understanding of the brain’s response to physical activity. For years, scientists have understood that regular physical activity positively impacts various c…
