The significance of a cool-down period after workouts lies in its ability to aid in recovery and prevent injury. Gradually decreasing the intensity of activity allows the heart rate to return to normal and helps to flush out lactic acid from muscles, reducing soreness. A proper cool-down also includes stretching, which promotes flexibility and reduces muscle tension. Skipping this essential phase can lead to lightheadedness or increased risk of strains. Incorporating a cool-down into fitness routines ensures a safer transition from high-intensity sessions back to a resting state, fostering long-term fitness success.
