Abstract:

The primary purpose of this paper is to determine whether a short sleep nap can maintain human cognitive functions during a long continuous work period. In continuous work environments, the normal 7-8 hour period of nocturnal sleep is not allowed. Instead, work continues in time periods longer than 24 hours. A long work period causes cognitive decrements due to fatigue and sleepiness. Can naps prevent such decrements More specifically, can a sleep wake schedule of a 20-min sleep every 6 hours prevent cognitive degradation during a continuous work period of 64 hours The present chapter reports on the effects of the 20-min340-min sleepwake schedule on cognitive functions during a 64-hr work period. The 20340 sleepwake schedule was chosen for the study on the basis of previously published experimental studies. They suggest that short naps prevent cognitive decrements during a long continuous work period.
