endorfiine

Endorphins are a class of opioid peptides produced by the pituitary gland and the central nervous system. The word "endorphin" is derived from "endogenous" and "morphine," meaning a morphine-like substance originating within the body. They are neurotransmitters that play a significant role in pain management and inducing feelings of pleasure.

Endorphins are released in response to various stimuli, including pain, stress, exercise, eating certain foods, and sexual activity. When endorphins bind to opioid receptors in the brain, they can reduce pain perception and create a sense of well-being or euphoria, often referred to as a "runner's high." This natural pain-relief mechanism is crucial for survival, allowing individuals to function even when injured.

The effects of endorphins are widespread. Beyond pain relief and mood enhancement, they are also implicated in regulating appetite, immune function, and stress responses. While often associated with positive feelings, their absence or dysregulation can be linked to conditions such as chronic pain and depression. Research into endorphins continues to explore their complex roles in both physical and psychological health.
