Endorfinelele

Endorfinelele are a group of peptide hormones produced by the pituitary gland and the hypothalamus in vertebrates. They function as neurotransmitters, acting on the nervous system to reduce pain perception and induce feelings of pleasure or euphoria. The term "endorphin" itself is a portmanteau of "endogenous" and "morphine," highlighting their natural production within the body and their similar effects to exogenous opiates.

These neuropeptides are released in response to various stimuli, including stress, pain, exercise, and even certain types of food or social interaction. Once released, endorfinelele bind to opioid receptors in the brain and spinal cord, blocking the transmission of pain signals and stimulating the release of dopamine, which contributes to the sensation of pleasure. While often associated with the "runner's high," the exact mechanisms and extent of endorphin release during different activities are still areas of ongoing research. Their role is not limited to pain relief and pleasure; they are also believed to play a part in mood regulation, appetite control, and the body's response to stress.
