Blood’s major purpose in the body is to carry nutrients (glucose and oxygen) to the cells and to carry waste out through our lungs in the form of carbon dioxide. When we exercise we increase blood flow throughout the body. The more you exercise the greater the blood flow. This means more nutrients and more waste removal. Exercise also increases blood flow into the Dentrate Gyrus. The Dentrate Gyrus is part of our brain’s Hippocampus, a region involved in memory formation and neurogenisis (birth of new neurons). Exercise also stimulates the production of Brain Derived Neurotrophic Factor (BDFN). BDFN is miracle grow for the neurons inside our brain. Exercise is, in many respects, like candy for the brain.
