What describes "acute fatigue" in the workplace?

Acute fatigue is characterized by a buildup of tiredness that occurs within a single waking period, usually as a result of intense physical or mental activity. This form of fatigue tends to arise quickly and can often be resolved with adequate rest or a brief break. It reflects a temporary state that is generally linked to the demands of a particular day or task, distinguishing it from chronic fatigue, which involves a longer-term experience of exhaustion, often linked to ongoing stress or insufficient rest over an extended time.

In a workplace context, recognizing acute fatigue is crucial for maintaining productivity and safety, as it can impair a person's ability to perform tasks effectively if not addressed in a timely manner.
