Endorphins are hormones released from the brain to help alleviate stress and pain. They also help elevate mood – as such, they qualify as one of the 4 “feel good” hormones along with dopamine, serotonin, and oxytocin. They are the body’s natural opioid. In fact, their name comes from the terms, “endogenous” (coming from within) and “morphine.”
The production of endorphins evolved in order to help us survive. When activated, pain (nerve) fibers transmit signals to the brain. Some branches go to the cerebral cortex, the “thinking and feeling” part of the brain, and we experience the unpleasant sensation called “pain.” Other pain fibers go to parts of the brain that are signaled to secrete endorphins, which then act to help relieve the pain. This is a very elegant system!
Other than by experiencing pain, how can we boost endorphine secretion?
We can do this with exercise, hence the so-called “runner’s high.” Some pleasurable acts also cause endorphin production, heightening the enjoyment. These include having a delicious meal, making love, having a massage, dancing, and having acupuncture.
There are other effects of endorphins on the brain. By inducing a “feel good” state, they improve our self-image and self-esteem. They ease symptoms of depression. They also help reduce anxiety and stress.
Once again, we emphasize the benefits of exercise: production of endorphins with the associated improvement in mood and self-worth; increase in bone density, cardiovascular and brain health; and sleep. When we are well rested and feel better about ourselves we tend to focus more on healthy eating.
Let’s go for a run, brisk walk, or bike ride, lift some weights, exercise our core, and generate some endorphins!
