Contrary to popular belief, most runners do not actually experience a "runner's high." Instead, that post-run euphoria can actually be chalked up to the body's production of endocannabinoids, a biochemical substance that is similar to cannabis but produced naturally by the body after vigorous physical activity (via John Hopkins Medicine).

Long after the run, the brain benefits from other changes that occur in the body upon implementing a daily running routine (one done in moderation). Runners who hit the pavement on a regular basis will likely also benefit from the growth of new blood vessels and brain cells prompted by exercise that can lead to an improvement in brain performance and prevent cognitive decline. Additionally, regular exercise can work wonders in regulating the brain's response to stress, which, in turn, has the potential to improve your day-to-day mood.

"Exercise has a dramatic anti-depressive effect," said David Linden, Ph.D. and professor of neuroscience at the Johns Hopkins University School of Medicine. In a post for JHM, Dr. Linden explained that exercise "blunts the brain's response to physical and emotional stress." Other brain-related benefits of running include improved memory, ability to focus, and multitasking capabilities.
