What role do endorphins play in the body?

Endorphins are neurotransmitters produced by the pituitary gland and the central nervous system, primarily functioning as natural painkillers. They bind to specific receptors in the brain and have a significant role in controlling pain perception and inducing feelings of pleasure and well-being. This is why they are often referred to as "feel-good" hormones. Physical activities such as exercise, laughter, and even certain foods can stimulate endorphin release, contributing to a sense of euphoria or a "runner's high."

While factors like sleep and relaxation, metabolic processes, and immune response involve various neurochemicals and hormones, they do not specifically describe the primary function of endorphins. Instead, the unique relationship endorphins have with pain modulation and the enhancement of pleasure distinctly highlights their crucial role within the body's biochemical landscape.
