When a lower threshold associated with stimuli due to trauma what does lowering the threshold indicate?

Lowering the threshold associated with stimuli due to trauma indicates that an individual becomes more sensitive to certain triggers or stressors. This heightened sensitivity can lead to an exaggerated response to stimuli that may not have previously elicited a strong reaction. Essentially, individuals may experience anxiety or distress more easily, as their nervous system is more reactive due to past traumatic experiences. This phenomenon is often linked to conditions like PTSD, where even benign cues can provoke significant emotional responses.
