The relaxed and feel-good sensation after long running is said to be giving almost the same effects that comes after using marijuana in any form.
The sensation is termed as runner’s high and it is common to hear someone saying “Ah, my endorphins are kicking in!” after the end of a good run.
It is said the Endorphins produces “runner’s high” and it gives the sense of calm and euphoria. Many people experience this after a satisfying workout.
However, researchers say the endorphins are wrongly credited for making the workouts enjoyable. It has little to do with it. In fact the euphoric feel comes from a different substance. It is because of the body’s own endocannabinoids.
Endocannabinoids are chemicals that results with lightening mood similar to what cannabinoids in marijuana does.
The term endorphins became a commonly known term in the 1980s when it was found the blood levels increases after longer exercise. It is rational exercise may cause discomfort or even pain, but the body’s self-produced opiates help in pain relief.
However, the endorphins are large molecules and cannot pass through the blood-brain barrier and hence it cannot effect inside the brain directly.
The new research now explains how the runner’s high is caused. It is said the endocannabinoids are responsible as the cannabis contain cannabinoid molecules and these are small enough to cross the blood-brain barrier.
The study was conducted by researchers at the Central Institute of Mental Health at the University of Heidelberg.
