Physical activity enhances cognitive performance from "summary" of Brain Rules (Updated and Expanded) by John Medina
When you move, you stimulate the production of a special substance called brain-derived neurotrophic factor (BDNF). This protein is like fertilizer for your brain, aiding in the growth of new neurons and synapses. Without it, your brain struggles to learn and remember things. In fact, research has shown that exercise can boost your cognitive performance by as much as 50 percent. Physical activity not only helps with the growth of new neurons, but it also increases blood flow to the brain. This means that more oxygen and nutrients can reach your brain cells, allowing them to function at their best. As a result, you will be able to think more clearly, focus better, and make decisions more efficiently. Moreover, exercising regularly can help protect your brain from the effects of aging. It has been found that older adults who engage in physical activity have a lower risk of developing cognitive decline and dementia. This is because exercise promotes the release of chemicals that protect your brain cells from damage and inflammation. In addition to its long-term benefits, physical activity can also have immediate effects on your cognitive performance. For example, going for a brisk walk or doing some jumping jacks can help you feel more alert and energized. This is because exercise triggers the release of neurotransmitters like dopamine and serotonin, which are known to improve mood and concentration.- Incorporating physical activity into your daily routine is one of the best things you can do for your brain. Not only does it enhance your cognitive performance, but it also boosts your mood, reduces stress, and promotes overall brain health. So, the next time you find yourself feeling sluggish or unfocused, try moving your body – your brain will thank you for it.
