What is the purpose of a cooldown after exercise?

The purpose of a cooldown after exercise is to gradually lower heart rate and prevent dizziness. During physical activity, the heart rate increases to supply more oxygen to the muscles due to heightened demand. Abruptly stopping exercise can cause the heart rate to drop too quickly, which may lead to dizziness or fainting. A cooldown involves engaging in low-intensity activities, allowing the heart rate to decrease gradually and facilitating a smooth transition back to a resting state.

This process also helps in improving circulation and promotes the clearing of metabolic waste products from the muscles, thus aiding recovery. Including gentle stretching during the cooldown can have additional benefits, but the primary focus remains on safely managing the heart rate and preventing any adverse effects following exertion.
