Nonverbal 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 friendliness, while crossed arms may suggest defensiveness. These signals often complement or contradict verbal messages, providing additional context to interactions. Understanding nonverbal cues is essential in various settings, such as business meetings, social gatherings, and therapy sessions. Different cultures may interpret these signals differently, making it important to be aware of cultural norms. Overall, nonverbal communication plays a crucial role in how we connect and understand one another.
