Fatigue Vs. Sleepiness
Fatigue is generally considered a more long-term condition than sleepiness (see Somnolence). Although sleepiness can be a symptom of medical issues, it usually results from lack of restful sleep, or a lack of stimulation . Chronic fatigue, on the other hand, is a symptom of a greater medical problem in most cases. It manifests in mental or physical weariness and inability to complete tasks at normal performance. Both are often used interchangeably and even categorized under the description of 'being tired.'

Famous quotes containing the word fatigue:
“Croft had an instinctive knowledge of land, sensed the stresses and torsions that had first erupted it, the abrasions of wind and water. The platoon had long ceased to question any direction he took; they knew he would be right as infallibly as sun after darkness or fatigue after a long march.”
—Norman Mailer (b. 1923)
