Physical activity is also known to increase the release of endorphins. These chemicals reduce feelings of pain. They also help people feel more happy and peaceful. There is some debate about exactly what causes the brain to release endorphins. Some experts believe it is the act of exercising itself. Others say it is the feeling one gets from having met an exercise goal. Either way, the two things work together when it comes to improving one’s emotional health.

FAITH LAPIDUS: Surprisingly, exercise improves your energy levels by increasing the flow of blood to the heart and blood vessels. One of the main reasons people exercise is to control or reduce their weight. Physical activity burns calories – the energy stored in food. The more calories you burn, the easier it is to control or reduce your weight.
So exactly how much exercise do you need to do to gain all of these great health effects? Experts say it is easier than you think. Two years ago, the Centers for Disease Control released its first ever Physical Activity Guidelines for Americans. The report included suggestions for young people, adults, disabled persons and those with long-term health problems. One of the major ideas noted in the report is that some activity is better than none. So if you are not doing anything, now is the time to get started.
BOB DOUGHTY: The C.D.C. defines physical activity as anything that gets your body moving. And, it says there are two separate, but equally important kinds of physical activity. Aerobic or cardio exercise gets your heart rate going faster and increases your breathing. Some examples are activities like walking at an increased speed, dancing, swimming or riding a bicycle.
