Sleep Debt
Sleep debt is the effect of not getting enough sleep; a large debt causes mental, emotional and physical fatigue.
Sleep debt results in diminished abilities to perform high-level cognitive functions. Neurophysiological and functional imaging studies have demonstrated that frontal regions of the brain are particularly responsive to homeostatic sleep pressure.
Scientists do not agree on how much sleep debt it is possible to accumulate; whether it is accumulated against an individual's average sleep or some other benchmark; nor on whether the prevalence of sleep debt among adults has changed appreciably in the industrialized world in recent decades. It is likely that children are sleeping less than previously in Western societies.

Famous quotes containing the words sleep and/or debt:
“England! awake! awake! awake!
Jerusalem thy sister calls!
Why wilt thou sleep the sleep of death,
And close her from thy ancient walls?”
—William Blake (1757–1827)
“I have been told, that in some public discourses of mine my reverence for the intellect has made me unjustly cold to the personal relations. But now I almost shrink at the remembrance of such disparaging words. For persons are love’s world, and the coldest philosopher cannot recount the debt of the young soul wandering here in nature to the power of love, without being tempted to unsay, as treasonable to nature, aught derogatory to the social instincts.”
—Ralph Waldo Emerson (1803–1882)
