Recovery from the fatigue and sleepiness incurred by persons in CW is usually accomplished by short sleep (naps) before embarking on another episode of CW. Data from 38 U.S. Marine Corps volunteers are presented to show that the restorative power of a 0400 to 0700 nap is sufficient to support post-nap performance of Four Choice task for an additional 20 hours. This early morning 3-hour nap has also reduced the rate of degradation of performance of subjects on Four Choice and Simple Reaction Time tasks, in comparison with those who worked without napping. To assure overall high quality performance in recurring episodes of CW, design of work/rest schedule should call for 3 hours or longer of recovery sleep even after CW as short as 20 hours. 收起
