Giggles

Giggles are brief, spontaneous bursts of laughter that often occur in response to humor, joy, or social interactions. They are usually light and contagious, reflecting genuine amusement or nervousness. Physiologically, giggles involve rhythmic contractions of certain facial and respiratory muscles, producing a distinctive, high-pitched sound. Common in children but also present in adults, giggles serve social functions by reinforcing bonds and signaling positive emotions. They are a natural part of human expression, contributing to social cohesion and emotional well-being.
