An outline allows a writer to categorize the main points, to organize the paragraphs into an order that makes sense, and to make sure that each paragraph/idea can be fully developed. Essentially, an outline helps prevent a writer from getting stuck when performing the actual writing of the essay.
sleep deprivation a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as prolonged periods of time without sleep (sustained, natural, periodic suspension of relative consciousness).
Sleep deprivation is the condition of not having enough sleep; it can be either chronic or acute. A chronic sleep-restricted state can cause fatigue, daytime sleepiness, clumsiness and weight loss or weight gain. It adversely affects the brain and cognitive function. However, in a subset of cases sleep deprivation can, paradoxically, lead to increased energy and alertness and enhanced mood; it has even been used as a treatment for depression (see below). Few studies have compared the effects of acute total sleep deprivation and chronic partial sleep restriction.
