Which type of stress is characterized as short term?

Acute stress is characterized as short-term stress that arises in response to specific and immediate challenges or threats. This type of stress can be caused by events such as a job interview, an exam, or a sudden change in circumstances. Acute stress is often seen as a normal reaction to these perceived challenges and typically resolves once the stressor is removed or the situation is managed.

In contrast, chronic stress is ongoing and persists over a longer period, often due to prolonged exposure to stressors such as difficult work conditions or ongoing personal challenges. Situational stress can relate to specific contexts but is not strictly defined by time. Transitional stress refers to the stress experienced during life changes, which can also vary in duration but is often associated with significant life transitions. Thus, acute stress is distinctly defined by its brevity and immediacy, making it the correct choice for this question.
