Nonverbal communication conveys at least 65% of social meanings in a conversation through body language rather than words. It includes facial expressions, gestures, eye contact, posture, touch, use of space, time, smell, tone of voice, and other physical aspects. Different nonverbal behaviors can signal various emotional states and interpersonal meanings, such as confidence from an erect walk versus dejection from hunched shoulders and hands in pockets. Being aware of nonverbal communication is important for fully understanding social interactions and expressing oneself clearly.
