What are endorphins known to do?

Endorphins are neuropeptides produced by the body that play a key role in pain relief and pleasure. They bind to opiate receptors in the brain, which helps to block pain signals and create feelings of euphoria. This natural mechanism is similar to how opioids work, but endorphins are produced naturally by the body in response to stress, pain, or vigorous exercise. The release of endorphins is often associated with phenomena like the "runner's high," where individuals experience a sense of well-being after physical activity.

This capacity to reduce pain makes endorphins particularly significant in various therapeutic and sports contexts, where managing pain or promoting recovery is essential. While other options relate to different physiological processes, they do not accurately capture the primary function of endorphins in the body. Thus, binding to opiate receptors and reducing pain correctly identifies the key action of endorphins.
