What is a type of fatigue characterized by short-term disruption?

Acute fatigue is characterized by a temporary state of tiredness that usually arises from a specific event or activity, such as physical exertion or lack of sleep. This form of fatigue is often short-lived, typically resolving after rest or suitable recovery measures are taken. In the context of fitness for duty and behavioral observation, recognizing acute fatigue is crucial because it can significantly influence an individual's performance and decision-making abilities in a short time frame. Identifying this kind of fatigue allows for appropriate interventions to be implemented, ensuring safety and effective functioning in the workplace.

Other types of fatigue, such as chronic fatigue or cumulative fatigue, involve longer durations and more persistent issues, which are not the focus of this question.
