What is characterized by a temporary pattern of stressor-activated arousal with a distinct onset and limited duration?

The concept of acute stress is defined by a temporary pattern of stressor-activated arousal that has a distinct onset and a limited duration. This type of stress typically arises in response to specific situations or events, leading to immediate physiological and psychological responses.

Acute stress is often experienced in situations that are perceived as threatening or challenging, and it usually resolves as the individual adapts to the circumstances or the stressor dissipates. For example, someone might experience acute stress during a significant life change, such as public speaking, an important exam, or after a near-miss traffic accident. Once the stressor is gone, the symptoms of acute stress generally diminish relatively quickly, often within a few days.

In contrast, chronic stress develops from prolonged exposure to stressors and persists over an extended period, which can have lasting implications for an individual's health and well-being. Critical incident stress refers to the immediate reactions following a traumatic event, but it may evolve into different stress responses over time. Post-traumatic stress disorder is a longer-lasting condition that arises after exposure to a traumatic event, characterized by symptoms such as persistent re-experiencing of the trauma, avoidance behaviors, and heightened arousal, which lasts for more than a month.
