PY - 2021 T2 - CURRENT Diagnosis & Treatment: Occupational & Environmental Medicine, 6e AB - Fatigue is defined as a biological drive for recuperative rest. It affects a large majority of workers. The major cause of fatigue is insufficient or disrupted sleep. Fatigue occurs as a function of the length of time awake, the time of day, workload, general health, and lifestyle outside of work. It is a function of the homeostatic drive for sleep and the circadian rhythm of sleep/wakefulness. Fatigue and excessive daytime sleepiness (EDS) are also consequences of disorders of the central or peripheral nervous systems and/or other disease states, including common illnesses such as infections, asthma, gastrointestinal disorders, and metabolic abnormalities. Attention to fatigue in workers is important, not only because it affects work and safety but because of the negative impacts of fatigue on overall health.
