You do fitness and supposedly it's endorphins that make you all happy and yummy about it. Really? Or is it something that was considered illegal not long ago?Is It The Endorphin Or Not?Most people know the endorphin effect in fitness as the "runner's high," but it also happens when weightlifting: a feeling of bliss and happiness.Claims go as far as saying that it's strong enough to make you dependent. The body's endorphins, after all, are the more friendly aunties of morphine, nature's strongest analgesic drug, most commonly found in opium.But wait a minute! How does an analgesic that reduces pain induce a high? Does that even work?Endocannabinoids, Serotonin, Dopamine, AdrenalineDespite 40 years of declarations that endorphins are responsible for the runner’s high, the evidence is slim. So far only one study claims to have found a difference in endorphin level after a run.Your brain on fitness produces stuff much more likely responsible, an entire rowdy band of it:
- Endocannabinoids, the body's answer to marijuana, as the name hints. Like endorphin they make you feel less pain, but also raise subjective well-being
- Serotonin, a hormone and neurotransmitter that influences mood
- Dopamine, another hormone, that plays the strings of the brain's reward and pleasure centers
- Adrenaline and noradrenaline, responsible for making your body ready for "fight or flight"
