What does a proper cool-down help prevent?

A proper cool-down is crucial because it helps prevent blood pooling in the extremities. After intense physical activity, the heart rate decreases rapidly, and if the body is not gradually brought back to a resting state, blood can pool in the veins of the legs and arms. This pooling can lead to lightheadedness or fainting because the body requires a gradual transition to a lower level of activity in order to maintain proper blood flow and circulation.

The cool-down process usually involves low-intensity movements and stretching, allowing the heart rate to decrease gradually and promoting venous return. This helps ensure that blood is effectively circulated back to the heart and organs, preventing potential complications associated with abrupt cessation of exercise.
