You’ve heard of a runner’s high, but did you know that the euphoric state fitness buffs claim to experience after intense exercise is bona fide?
According to a study reported in the journal Cerebral Cortex, running actually draws out a flood of endorphins in the brain. The endorphins then attach themselves to areas of the brain associated with emotions.
Dr. Henning Boecker and his team at the University of Bonn examined PET scans of athletes at rest and two hours post-run and found the level of euphoria and endorphins were significantly higher after they had finished their run.
The study not only demonstrates it is possible to define and measure a runner’s high–but what brings it on. That means one day, exercisers may be able to pin down exactly what it takes to elicit the endorphin rush that makes working out so addictive (in a good way).
