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 bind to the same receptors in the brain as morphine, which is why they can help alleviate pain. The release of endorphins can also improve mood and promote a sense of relaxation, making them an important part of the body's response to stress and discomfort.
