Engaging in sustained moderate to vigorous physical activity is an effective stress management technique because during physical activity, the body's:

cardiorespiratory system requires minimum levels of oxygen, thus contributing to muscle relaxation.

nervous system signals the pituitary gland to release neurotransmitters that help elevate mood.

Engaging in sustained activity boosts mood through brain chemistry. When you exercise, the nervous system signals the pituitary gland to release mood-related neurotransmitters, including endorphins, serotonin, and dopamine. These chemicals interact with brain circuits to elevate mood, reduce perceived stress, and improve overall well-being during and after the activity. This is why physical activity is an effective stress management technique. The other ideas don’t fit how the body responds to exercise: the body increases oxygen use to meet higher metabolic demands, stroke volume isn’t reduced to feel rested during activity, and melatonin from the pineal gland is tied to sleep, not immediate mood elevation from exercise.

cardiorespiratory system's need for a lowered stroke volume causes the body to feel rested.

nervous system signals the pineal gland to release melatonin, thereby initiating the need for sleep.
