Step 1

Endorphins are a type of neurotransmitter, or chemical messenger. They help relieve pain and stress. The term "endorphins" comes from the words "endogenous," which means from within the body, and "morphine," which is an opiate pain reliever. Show more…

Key Concepts

Endogenous Opioids

As a subgroup of endogenous opioids, endorphins act similarly to opiate drugs such as morphine by reducing pain sensations in the body. They are part of the body’s natural defense against stress and pain.

Vigorous Exercise

Vigorous exercise is known to stimulate the production and release of endorphins. The increase in these chemicals during physical activity contributes to the phenomenon often referred to as a 'runner's high', enhancing mood and reducing discomfort.

Endorphins

Endorphins are naturally occurring peptides in the brain that function as neurotransmitters. They help modulate pain and stress by binding to opioid receptors, leading to pain relief and feelings of euphoria.

Pain Response

The pain response is a physiological reaction to injury or harmful stimuli, which can trigger the release of endorphins. This release serves as a natural mechanism to alleviate pain and encourage recovery.
