More than 65% of communication is non-verbal, including gestures, signals, signs, posture, tone of voice, and facial expressions. The non-verbal cues can be ambiguous as the same gesture may have multiple meanings and feelings can be expressed differently. Facial expressions, especially smiling, are important in communication as 70% is understood through the face. Gesticulation with the hands also conveys significant meaning about mood and should align with verbal messages. It is best to communicate non-verbally in a natural way rather than consciously manipulating body language.
