What does a cool-down routine help to do after exercise?

A cool-down routine is designed to ease the body into recovery after exercise. During intense physical activity, the heart rate increases, blood vessels dilate, and various physiological changes happen to support performance. Engaging in a cool-down helps gradually bring the heart rate and blood pressure back to their pre-exercise levels.

This transition phase is crucial as it aids in the removal of metabolic waste products like lactic acid from the muscles, reduces the risk of dizziness or faintness that can come from a sudden halt in activity, and prevents muscle stiffness and soreness by enhancing blood circulation. Therefore, completing a cool-down routine is essential for effective recovery, helping the body to relax and heal after exertion.

The other options do not resonate with the primary function of a cool-down; they address different aspects of exercise rather than the recovery process post-activity.
