Quizplus · Accepted Answer

Endorphins are neuropeptides that act as natural painkillers and produce a feeling of euphoria, which is commonly known as a "runner's high." Endorphins are released by the anterior pituitary gland during exercise, which can help explain why your friend feels extra happy after a run. Releasing hormones stimulate the release of hormones from other glands, prolactin is involved in lactation and milk production, and adrenaline is typically associated with the body's "fight or flight" response to stress.
