What is the physiological basis for the "runner's high" phenomenon ?
The runner's high is a state of euphoria experienced by long-distance runners, believed to have a physiological basis. Endorphins, natural opioid peptides that reduce pain perception and create feelings of pleasure, are key players in this phenomenon. Other factors like adrenaline, norepinephrine, serotonin, dopamine, and cortisol also contribute. The benefits include pain relief, mood enhancement, stress reduction, and improved self-esteem.
