Which of the following is NOT a non-verbal cue indicating a potential threat?

A relaxed posture is generally a sign of comfort and ease, indicating that a person is not feeling threatened or aggressive. In contrast, non-verbal cues indicating a potential threat typically involve signs of tension, stress, or agitation.

Increased breathing, clenched fists, and a reddened face are all physical manifestations that can suggest heightened emotion, such as anger, fear, or anxiety, which are often associated with a potential threat. These cues generally alert an observer to be cautious as they could precede aggressive behavior or conflict. Therefore, a relaxed posture distinctly contrasts with the other cues, marking it as an indicator of safety rather than a warning sign.
