Body language is a form of non-verbal communication that conveys messages through physical behaviors such as facial expressions, gestures, eye contact, posture, and tone of voice. Positive body language includes open palms, direct eye contact, smiling, and firm handshakes which indicate an open personality and honesty. Other cues like eye contact, smiles, hand gestures, and leg positions provide insights into a person's emotions, thoughts, and social behaviors. Body language plays an important role in how we perceive and interact with others.
