Non-verbal communication refers to the ways people convey messages without using words. This includes body language, facial expressions, gestures, posture, and eye contact. For example, a smile can indicate happiness, while crossed arms may suggest defensiveness. Non-verbal cues often enhance or contradict verbal messages, providing additional context to communication. In many situations, non-verbal signals can be more powerful than spoken words. For instance, in public speaking, a speaker's confidence can be conveyed through their stance and eye contact. Understanding non-verbal communication is essential in various fields, including psychology, business, and interpersonal relationships, as it helps interpret emotions and intentions.
