It is now being suggested that it’s not totally correct to give “Endorphins” all the wrap when talking about the reported feeling of euphoria after an exercise session. Studies have shown that Endorphin molecules are quite large and can’t pass through the blood-brain barrier. So therefore, a runner’s ‘high’ could be due to other substances with smaller molecules that can reach the brain.
In 2003, scientists at the Georgia Institute of Technology found that 50 minutes of hard running on a treadmill or riding a stationary bicycle significantly increased blood levels of endocannabinoid molecules in a group of college students. This natural substance released by the body is similar of that to the active chemicals in Cannabis (Marijuana).
So until more research can conclude that Endocannabinoids really are what makes us feel so good after exercise (and may even encourage us to exercise in the first place) – I’m going to conclude that running and exercise is just truly addictive! Experiment with it!
