What is the purpose of a cool-down period after a workout?

The purpose of a cool-down period after a workout is primarily to lower body temperature. After intense exercise, the body tends to generate a significant amount of heat, and the muscles are typically in a heightened state of activity. The cool-down allows the heart rate and body temperature to gradually return to their resting states, which helps to prevent dizziness and fainting that might occur if vigorous exercise is abruptly halted.

Additionally, cooling down helps to facilitate the removal of metabolic waste products from the muscles, which can reduce the risk of muscle soreness. This gradual transition also aids in recovery and prepares the body for future workouts. It is also a time when one can incorporate stretching, which contributes to flexibility, but its main function is to assist in lowering heart rate and body temperature effectively.
