Cool Down
The two scientific reasons to cool down are to allow your heart rate to return to a normal, resting rate gradually instead of suddenly, and to provide lactic acid relief. The first is probably the most important. A sudden cessation of activity can create a lot of rapid changes in the body that place undo strain on the heart.
A cool down means you are still moving your body but just at a slower rate. For example, if you are running or biking, a cool down would include biking or running at a much slower rate than you were exercising. Stretching is usually done as the last step of a cool down.
