Exercise is not only beneficial for physical health but also for cognitive and mental well-being. Research has shown that physical activity can lead to a plethora of cellular changes in the brain, ultimately improving mood and cognition. Studies have indicated that immediately after engaging in physical activity, individuals perform better on tests of working memory and executive functions, due to the increase in neurotransmitter release in the brain.
Dr. Henriette van Praag, an associate professor of biomedical science at Florida Atlantic University, discovered the potential of exercise to stimulate the growth of new brain cells in mature mice while working at the Salk Institute for Biological Studies in San Diego. This groundbreaking finding has influenced her personal approach to fitness, leading her to take exercise more seriously, incorporating activities such as CrossFit and running into her routine.
While the debate continues regarding whether exercise can induce the growth of new neurons in adult humans, the benefits of physical activity for the brain are undeniable. The release of neurotransmitters, including epinephrine, norepinephrine, dopamine, and serotonin during exercise, plays a crucial role in attention, working memory, and executive functioning.
Furthermore, the positive impact of exercise on cognitive and mental health extends beyond the immediate short-term effects. Long-term engagement in physical activity has been associated with improved overall brain health, offering potential benefits for individuals at risk of neurodegenerative diseases.
