Runners Experience A High Similar to People Who Take Drugs
We all know runners (you may be one), the sort that runs in all conditions, does so in what seems to be some sort of religious dedication that sometimes appears to defy reality. It is like they are high -- which is exactly how many runners describe the feeling that overcomes them.
Science knows why! It has found that rhythmic, continuous aerobic exercise, like running, produces narcotic-like chemicals in the body during and immediately after exercise.
Natural chemicals similar to opium and marijuana are manufactured in your brain.
Endorphins, such wonderful things. A study done in 2008 found that during 2 hour long runs, the part of the brain that gushed endorphins was the same part of the brain that lights up when responding to emotions like love. This might explain the euphoric feelings reported by many runners. But science isn't able to make these claims with complete certainty as this study was done with a really small sample (10, already fit runners). Because endorphins vary between people they can't explain what effect they actually have on a person's psyche. Want to know what science is willing to say? There is a lot of evidence that points to your brains producing a natural chemical similar to marijuana after moderate intensity exercise. Endocannabinoids, is a naturally synthesized version of the same chemical the gets you high but it can have an even greater effect on your body. Unlike endorphins which are only produced by specific neurons in your brain, any cell in your body can produce endocannabinoids.It goes back to your ancestors.
It appears that this ability to get "high" while running is hard wired into us. Many anthropologists believe that our survival depended on our ability to chase down our prey to exhaustion. The ability to produce endocannabinoids is what helped them get it done. David A. Raichlen, a professor of anthropology at the University of Arizona tested this theory. He found an excess of endocannabinoids in distance running animals like dogs (and humans) but found no trace of it in non distance runners like ferrets. Evolution, baby!
