"Laugh" is a joyful sound we make when something is funny or brings us happiness. It often involves a series of quick breaths and can be accompanied by smiles or even tears of joy. Laughing helps us connect with others and can lighten the mood in any situation. It's a natural response that everyone, from babies to adults, experiences. When we laugh, our brains release chemicals called endorphins, which make us feel good. This is why sharing a joke with a friend or watching a funny movie can brighten our day. Laughter is not just a reaction; it's a powerful tool for bonding and improving our overall well-being.
