As a runner and a scientist, I’ve always wondered about runner’s highs. Highs, not Thighs! Maybe I get them (the highs, I definitely get the thighs!), maybe I don’t, but I do know that after 7+ miles I feel like I could run forever. Is that what a runner’s high does?
After any distance of running, I feel happy. Maybe my knee hurts a bit, maybe my muscles are tight (especially after hills), but I feel good, both physically and emotionally. I run to thrive. Getting a runner’s high though? For myself, I can’t say one way or another.
However, via Scientific Blogging …
Up until now, it was widely believed and accepted that endorphins released during exercise were responsible for a runner’s high, but it was not PROVEN. These studies involved 10 athletes, 2 hours of jogging, positron emission tomography (PET) and a radioactive material that binds to opiate receptors in the brain. Using the PET they could compare images of the athlete’s brains before and after the 2 hours of jogging and noticed an increase of opiates in some areas of the brain!
Get out there and get your high today!
(I’m also extremely curious to know if you get them, how long it takes, how it makes you feel, etc!)
