What is the term for fatigue resulting from a lack of rest over a single night?

The term for fatigue resulting from a lack of rest over a single night is known as acute fatigue. This type of fatigue arises quickly and is typically a result of insufficient sleep or a single night of rest deprivation. It is characterized by a sudden onset of tiredness and a decrease in performance, which can affect cognitive function, mood, and physical capabilities.

Chronic fatigue, on the other hand, refers to prolonged fatigue that may last for an extended period and is often attributed to various underlying health conditions or continuous stress. Momentary fatigue implies a very brief or transient period of tiredness, which doesn't accurately encompass the effects of missing sleep for just one night. Intermittent fatigue describes fatigue that occurs in cycles, which is not specific to the immediate effects of a single night without sufficient rest. Thus, acute fatigue is the most accurate term in this context, as it directly correlates to the experience of fatigue following a lack of sleep over a short time frame.
