Endorphins are natural chemicals produced by the body that help relieve pain and reduce stress. They are often referred to as "feel-good" hormones because they can create feelings of happiness and euphoria. Endorphins are released during activities like exercise, laughter, and even eating certain foods, contributing to an overall sense of well-being. These neurotransmitters work by binding to the same receptors in the brain as morphine, which is a powerful pain reliever. This interaction helps to diminish the perception of pain and can lead to a temporary boost in mood. Regular physical activity is one of the most effective ways to increase endorphin levels.
