Body language plays a significant role in non-verbal communication, conveying emotions and attitudes without words. For instance, rubbing the face, palms, or neck often indicates feelings of anxiety or stress. Similarly, crossing arms with clenched fists tends to express hostility or impatience, while crossing arms in a way that grips the other arm can suggest insecurity or self-doubt. In contrast, crossed arms with a thumbs-up can reflect interest and engagement, although sometimes crossing arms simply means a person feels cold.

Fidgeting or squirming can signal discomfort, insecurity, or even dishonesty, revealing inner turmoil. Moreover, standing with hands positioned behind the back is often associated with a sense of power or superiority. Understanding these gestures allows for better interpretation of non-verbal cues in social interactions, as outlined in Susan C. Young's book "The Art of Body Language." Recognizing these signs can lead to more effective communication and an understanding of the underlying emotions being expressed.
