ABSTRACT

Objective: To study the effect of 30-min nap at three low points of the rhythm during 40-hours sleep deprivation on continuous adding. Methods: Eight young subjects with normal sleep-wake habits were subjected to nap and total sleep deprivation conditions at an interval of 2 weeks. The whole experiment was from 600 of the first day to 2200 of the second day, totally 40 hours. There were three times of nap which lasted 30 min every time, 1300(the first day), 100 and 1300(the second day). Continuous adding was given separately at the time before experiment,1300 and 1800 of the first day, 100,600,1300,1800 and 2200 of the second day.and 2 days after the experiment;reaction times and wrong numbers were recorded. Results: Whether sleep deprivation with or without naps, the reaction time was prolonged.Compared with total sleep deprivation, the reaction time was shortened significantly at SD24, SD31 and SD40 when naps were introduced. Whether sleep deprivation with or without naps, the number of wrong answers did not change. Conclusion:Nap has positive effects during sleep deprivation.
