 * __What happens to the brain when exercising?__

** Regular physical activity might improve how well your brain functions. You probably know that exercise is important to keep your body healthy, but it might do wonders for your mind, too. Research is showing several positive effects of exercise on the brain, including:
 * Enhanced mood
 * Improved memory
 * Increased brain blood flow
 * Delayed or slowed progression of Alzheimer's disease
 * Reduced brain damage after injury

"Animal studies give us insight into what happens inside the brain during exercise. Mice love running, so they were given running wheels and allowed to voluntarily exercise. When compared with mice that did not exercise, the exercising mice had an increased number of new brain cells in the hippocampus—a part of the brain involved in learning and memory. Therefore, when you exercise you may increase the number of neurons in your brain." - [|http://www.thirdage.com/ebsco/files/13409.html]

- Helps to retrieve memories and create new ones. - Exercise increases the number of brain cells in the hippocampus which, in turn, increases memory and allows more space for memories to be stored.
