Cooling down after high-intensity workouts is important for several reasons. It helps gradually lower the heart rate and blood pressure, preventing dizziness or fainting. A proper cool-down also aids in recovery by reducing muscle soreness and stiffness, promoting flexibility. Stretching during this phase can relieve tension and enhance the range of motion in muscles that have been worked hard. Furthermore, cooling down allows the body to transition effectively from an intense state, making it easier to resume normal activities and maintain overall fitness levels.
