Physical activity and exercise are critically important for the health of both brain and body. Staying active and obtaining appropriate amounts of exercise reduces the risk of cardiovascular disease, overweight / obesity, abnormal hormonal fluctuations, and immune system dysfunction--all factors that have been connected to cancer. Physical activity promotes release of endorphins, excretion of toxins and waste, and increased distribution of oxygen and other macro- and micronutrients.
Prevention strategies? Stay physically active! Obtain regular exercise—do what you can at least 3-5 x a week.
