Regular exercise can improve cognitive function from "summary" of Mente afiada by Sanjay Gupta
Regular physical activity has been shown to have a positive impact on brain health. When we exercise, our heart rate increases, leading to improved blood flow to the brain. This increased blood flow delivers more oxygen and nutrients to brain cells, which can promote the growth of new blood vessels and even new brain cells. As a result, regular exercise can help to improve cognitive function, including memory, attention, and decision-making skills. In addition to increasing blood flow to the brain, exercise has also been found to stimulate the release of chemicals called neurotransmitters, which play a key role in brain function. For example, exercise can lead to the release of endorphins, which are known to improve mood and reduce stress. Similarly, exercise can trigger the release of dopamine, a neurotransmitter that is involved in motivation and reward. By influencing these neurotransmitter systems, exercise can help to enhance cognitive function and overall brain health. Furthermore, regular physical activity has been linked to the production of brain-derived neurotrophic factor (BDNF), a protein that promotes the growth of new neurons and strengthens existing connections between brain cells. BDNF is essential for learning and memory, and research has shown that exercise can increase its levels in the brain. By promoting the production of BDNF, exercise can support the brain's ability to adapt and learn new information, leading to improved cognitive function.- The evidence is clear: regular exercise is not only beneficial for our physical health but also for our brain health. By increasing blood flow to the brain, stimulating neurotransmitter release, and promoting the production of BDNF, exercise can help to improve cognitive function and protect against age-related cognitive decline. So, lace up those sneakers and hit the gym – your brain will thank you for it.
