What is a common characteristic of an individual experiencing a panic attack?

The common characteristic of an individual experiencing a panic attack is the sudden onset of sweating and increased heart rate. During a panic attack, the body reacts with a "fight or flight" response, which can trigger physical symptoms such as rapid heartbeat, heavy sweating, trembling, and shortness of breath. These physiological responses can occur unexpectedly and reach their peak intensity within minutes, leaving individuals feeling overwhelmed and frightened.

This characteristic aligns with the body's natural response to perceived threats, which is why the symptoms manifest so dramatically. Panic attacks can be frightening experiences that often involve a sense of impending doom, and the physical symptoms are major contributors to these feelings, heightening the distress one feels during such an episode.
