Endorphins are among the brain chemicals known as neurotransmitters, which function to transmit electrical signals within the nervous system. Stress and pain are the two most common factors leading to the release of endorphins. I wanted to know if they are addictive, and found some contradicting answers:
If people can get addicted to risky sports just for the thrills they provide, they can also get addicted to painful activities where endorphins provide relief, "despite the harm to self and/or others," says Dr. Anna Lembke, chief of addiction medicine at Stanford University School of Medicine in an email interview. "For example, someone who compulsively cuts herself for the endorphin release is causing self-harm. Someone who compulsively runs, even to the point of causing musculoskeletal injury, is causing self-harm."
In contrast to the opiate drugs, however, activation of the opiate receptors by the body's endorphins does not lead to addiction or dependence.
If they are not, how can we explain the 'love' for pain in (this content might be sensitive for some of you) some people?
