It is widely believed that a full night s sleep is an unnecessary, inefficient luxury. However, this belief is even stronger in military and political settings in which a reduced need for sleep is seen often as a badge of honor. Throughout history, it has been reported that many noted individuals eg, Alexander the Great, Napoleon Bonaparte, and Winston Churchill only slept a maximum of 4 to 6 hoursday. Whether they slept for a short time every day and did not get longer sleeps andor naps regularly is open for debate. More importantly, whether these individuals performed at an optimal level is another issue for discussion, which leads to the following questions How is sleep assessed quantitatively What measurable performance effects exist By addressing these questions, a clearer picture of minimum and optimal sleep needs emerges. Throughout this chapter, there are specific terms used to describe this process and the performance measures affiliated with it, including sleep, sleepiness, circadian, fatigue and impairment.
