What nonverbal communication may indicate nervousness?

Biting one's lip is a common nonverbal cue that can signify nervousness or anxiety. This behavior may arise as a subconscious effort to manage the stress or discomfort one feels in a particular situation. It can signal to others that the individual is uncertain, apprehensive, or feeling pressure. Nonverbal communication often conveys emotions and states of mind, sometimes even more effectively than words.

In contrast, smiling frequently may typically be associated with friendliness or approachability, maintaining an open posture usually conveys confidence and openness, and nodding while listening often indicates understanding or agreement. These other choices do not communicate nervousness but rather express positive engagement or comfort in social interactions.
