What is the purpose of a cooldown after exercise?

The purpose of a cooldown after exercise is to gradually lower the heart rate and prevent dizziness. During vigorous physical activity, the heart rate increases significantly to supply muscles with more oxygen and energy. A cooldown helps to bring the heart rate down in a controlled manner, which can help prevent sudden drops in blood pressure. This gradual transition can also aid in the prevention of dizziness or lightheadedness that might occur if one were to stop exercising abruptly. Additionally, cooling down can promote overall recovery by allowing for a more effective removal of metabolic waste products from the muscles and reducing the risk of muscle soreness by keeping blood flowing to the tissues.
