QD: News Every Day--Jogging leads to longevity, but it's more like addiction

Joggers may live longer and be happier, but the euphoria might just be more like the response some addicts experience.

Research presented at a conference suggested that jogging does work for longevity. Modest jogging from 1 to 2.5 hours per week divided into two or three sessions at a self-described slow to average pace was associated with a 44% reduction in the relative risk of death over 35 years compared with deaths among non-joggers, MedPage Today reported.

The "runner's high" is anecdotally well-documented, so researchers tried to put a little data behind it. They compared dogs, notable long-distance runners, to ferrets, which are not, reported NPR. Dogs naturally produced cannabinoids, and the ferrets didn't.

Physicians in the story reported addiction-like responses among their patients, including those who mentally fall apart when injuries force them to rest instead of run.
