Which neurotransmitter is often referred to as "the feel-good" hormone due to its mood-enhancing effects?

Endorphins are often referred to as "the feel-good" hormones because they play a significant role in pain relief and pleasure. They are released during activities such as exercise, laughter, and even eating certain foods, leading to a sense of well-being and euphoria. These neuropeptides interact with the brain's opiate receptors to reduce the perception of pain and induce feelings of happiness or bliss.

While other neurotransmitters such as dopamine and serotonin also contribute to mood regulation and feelings of pleasure, endorphins are specifically associated with the body's natural mechanism for coping with pain and stress, which enhances their reputation as "feel-good" hormones. This is particularly evident in scenarios like "runner's high," where intense physical activity promotes endorphin release, leading to a euphoric feeling.
