Definition and meaning
Body language is the non-verbal information communicated through physical gestures, posture, facial expressions, eye contact, and movement. In presentations and public speaking, body language plays a critical role in how the speaker's confidence, credibility, and emotional state are perceived. Open posture, deliberate gestures, and sustained eye contact signal confidence and engagement, while crossed arms, fidgeting, and avoiding eye contact can suggest nervousness or disinterest. Presenters who master their body language are generally more persuasive and trustworthy.
