During a cooldown period after exercise, several physiological changes occur, including a gradual reduction in heart rate and blood pressure, which helps return the body to its resting state. Muscles also receive enhanced oxygen delivery during this time, facilitating lactate clearance and reducing soreness. Stretching during cooldown can improve flexibility and decrease muscle tension, contributing to recovery. Moreover, this period aids in mental relaxation, allowing individuals to reflect on their workout and physically transition back into daily activities.
