What is the primary role of endorphins in the body?

Endorphins play a crucial role in the body's pain management system. They are neuropeptides produced by the central nervous system and the pituitary gland. One of the primary functions of endorphins is to reduce the perception of pain, acting similarly to opioids by binding to specific receptors in the brain that help alleviate discomfort. This pain-relief mechanism is particularly important during moments of physical stress, injury, or emotional distress, contributing to what is often referred to as the body's natural pain relief system.

In various situations, such as intense physical exercise, the release of endorphins leads to what is commonly known as the “runner's high,” a state that can elevate mood and reduce feelings of pain. Thus, the primary role of endorphins as agents of pain relief is substantiated by their effects on both physical and emotional well-being. As a result, they are part of the body's response to stress and injury, fundamentally linked to feelings of euphoria and getting through challenging situations.
