What cue might indicate that an individual is experiencing pain?

A facial grimace can be a significant indicator that an individual is experiencing pain. This involuntary facial expression often signals discomfort or distress, and it serves as a non-verbal cue that observers can recognize. People may involuntarily contort their facial muscles when in pain, displaying signs such as furrowed brows, tight lips, or clenched teeth. These expressions arise as a natural response to physical discomfort and are widely understood across different cultures as signals of suffering.

In contrast, excessive talkativeness, increased energy levels, and relaxed posture do not typically correlate with the experience of pain. In fact, these behaviors often suggest a state of comfort or positive emotional engagement rather than distress. Therefore, recognizing a facial grimace as a cue for pain can lead to timely intervention and care for the individual experiencing discomfort.
