Laughter

Laughter is a complex physiological and psychological response to humor or social stimuli, involving rhythmic contractions of facial muscles, respiratory patterns, and release of endorphins— the body's feel-good chemicals. It serves as a social bonding tool, signaling friendliness and reducing tension. Neurologically, laughter activates areas in the brain associated with reward and emotional regulation. While often triggered by humor, it can also result from social cues, surprise, or even nervousness. Overall, laughter enhances social connection, relieves stress, and contributes to emotional well-being.
