Body language is a form of non-verbal communication that conveys information through gestures, posture, expressions, and eye movements. Around 55% of communication is non-verbal. Body language includes kinesics (body movements), proxemics (use of space), and haptics (touch). Maintaining eye contact, nodding, keeping an open posture, and smiling can communicate confidence and interest, while avoiding crossed arms, excessive fidgeting, and poor posture can undermine non-verbal messages. Understanding one's own body language and reading that of others is an important communication skill.
