The purpose of a cool-down period after exercise is to gradually lower the heart rate and help the body transition back to a resting state. This phase typically includes light physical activity and stretching to promote flexibility, aid in muscle recovery, and prevent soreness. Cooling down helps reduce the risk of dizziness or fainting by preventing sudden blood pooling in the extremities. Additionally, it facilitates the removal of metabolic waste products from muscles, reducing the likelihood of stiffness and soreness later. A proper cool-down can enhance overall recovery and prepare the body for future workouts.
