What is the primary purpose of a cool-down after exercise?

The primary purpose of a cool-down after exercise is to gradually lower heart rate. Following a workout, the body is in a state of heightened activity, and suddenly stopping can lead to blood pooling in the extremities, potential dizziness, or even fainting. A proper cool-down allows the heart rate to return to its resting state in a controlled manner, which is important for cardiovascular health.

Additionally, cooling down can help facilitate the clearance of metabolic waste products from the muscles, reduce the risk of muscle stiffness, and promote recovery while preventing injury. Gradual decreases in intensity during the cool-down phase also support normal physiological adjustments in vascular and respiratory function after exercise, further highlighting the importance of this practice in any fitness routine.
