Nonverbal communication refers to communicating without words through body language, gestures, facial expressions, eye contact, posture, touch, personal space and other signals. It accounts for 65% of daily communication. Different cultures have distinct nonverbal communication styles - for example, the Chinese avoid body contact, Argentinians greet with handshakes and nods, Indians greet with namaste, while Americans communicate informally with handshakes, smiles and hellos. Nonverbal communication plays an important role in how people interact and perceive one another across cultures.
