Body language plays a large role in communication, with some studies showing it accounts for up to 93% of communicated messages. Key components of body language include facial expressions, gestures, stance (open or closed), use of space, and eye contact. Maintaining an open, engaged stance through good posture, occasional nodding, eye contact and smiling can help communicate interest, while crossed arms, poor eye contact and slouching may signal disinterest or defensiveness. Understanding body language can provide important nonverbal context to conversations and interactions.
