Facial expressions, eye contact, gestures, and appearance are key aspects of non-verbal communication. Facial expressions convey feelings through smiles, frowns, and eyebrow movements. Eye contact expresses interest and respect between individuals and reveals what is on someone's mind. Gestures vary across cultures and religions but are commonly used to emphasize points when speaking. Non-verbal communication accounts for 65% of communication, playing an important role in daily interactions by sending messages without words through dress, gestures, and body language.
