Which of the following might indicate a delayed stress reaction?

A delayed stress reaction often manifests through symptoms that occur well after the initial traumatic event, rather than immediately. Changes in sleep patterns months after a trauma are a classic indicator of such a reaction. This can include insomnia, nightmares, or other disruptions in sleep, all of which are common responses to unresolved stress and trauma.

In contrast, quick responses during emergencies reflect a healthy acute stress response to immediate danger, not a delayed reaction. Physical injuries sustained at the time of the event are direct consequences of the trauma but do not indicate a delayed reaction; they are experienced right at the moment of the incident. Instant emotional responses to stressful scenarios also denote an immediate reaction to the stressful event, which does not align with the characteristics of a delayed stress response. Thus, changes in sleep patterns occurring well after the trauma are indicative of the complexities of processing and dealing with stress over time.
