 Not only is exercise vital for our physical well being, it is essential for mental well-being! Exercise increases the heart rate, which in turn increases oxygen to every part of the body, and oxygen is especially important for the brain. Aerobic exercise is the best way to supply oxygen to the brain. In addition, aerobic exercise also neutralizes stress, which can be especially harmful to the brain. Stress reduces our mental abilities considerably while at the same time causing the body to divert resources away from the brain and into the rest of the body in preparation for either “fight or flight.” The cortisol released when we experience stress can remain in the body for up to 2-1/2 days, continuing to impair brain function. Exercise rids the body of cortisol. Aerobic exercise also causes the release of neurotrophins, which help the brain to create new connections and keep everything functioning more smoothly. Research also shows that regular exercise specifically increases blood flow to the areas of the brain involved with memory. |
