Any distance runner will have the ability to attest to this sense of leisure and calm after happening a protracted & tiring run. They gain an unnatural amount of energy and “happy feeling”. This is even though they were just part of this dreaded & physically taxing exercise which essentially works out all the muscles in your body. Until now, a strong release of endorphins was given all the credit.

The study, published this week in Proceedings of the National Academy of the Sciences, looked at mice and found that what we understand to be a runner’s high doesn’t actually come from endorphins, but instead endocannabinoids that the body naturally produces.
Running is known to boost blood levels of β-endorphins, previously associated with subjective feelings of well-being often characterized as runner’s high. These molecules are small enough to cross into the brain and attach to receptors to create that runner’s high sensation. Endorphins are big molecules, and are too large to fit through the brain’s gatekeeper – the blood-brain barrier. That is what compelled researchers to imagine that they could not be what was making runners excessive since they could not slip by means of & connect themselves to the receptors of the mind.
Researchers have spent the last decade looking for other explanations, which led them to cannabinoids.
To be sure that endocannabinoids are at play and not endorphins, researchers with the Central Institute of Mental Health at the University of Heidelberg medical school in Mannheim, Germany, gathered a group of lab mice, tested their anxiety levels and then let them run. And it’s not the endorphins.
In the research scientists found higher levels of endocannabinoids (natural type) in people’s and animals’ blood. That is what made them take the examine ahead.
The mice were then let to run freely on wheels, which they particularly enjoy to do since the researchers didn’t have to go to any effort to convince the rodents.
They recommended that the rodents have been feeling one thing like runner’s excessive that’s the reason they discovered it good to run. It is unlikely that they cared about their health or were trying to lose weight.
To determine how eager lab rats were for physical exercises, scientists have removed the tread mill from the mice’s cage and observed their behavior over a given period of time.
The researchers compared endorphins’ and endocannabinoids’ effects. When they blocked the effects of endocannabinoids, the runner’s high symptoms vanished, according to Business Insider.
The researchers found that, in addition to appearing more calm less sensitive to pain after running, the mice had higher levels of both endorphins and endocannabinoids.

The mice were running three miles a day though so this may not be something amateurs can attempt though.
