Question

Quizplus · Accepted Answer

The feeling of euphoria following vigorous exercise is commonly referred to as a "runner's high" and is believed to be due to the release of endorphins, natural pain-relieving substances produced by the body. Endorphins can induce feelings of pleasure and well-being and are also thought to play a role in reducing anxiety and depression. While dopamine, acetylcholine, and norepinephrine may also be involved in the regulation of mood, the release of endorphins is most closely linked to the feeling of euphoria following exercise.
