Title Effect of continuous work and sleep loss in the reduction and recovery of work efficiency.
Bibliographic information Jan. 1974, Vol.35, No.1, p.13-20. Illus. 21 ref.
Abstract The average performance of 3 groups of 10 subjects was determined using a test battery of 6 tasks following 36, 44 and 48 hours of continuous work and sleep loss. The reduction in over-all performance efficiency was found to be 15%, 22% and 34%, respectively. 12 hours of sleep are sufficient to ensure complete recovery of performance after 36 hours of continuous work. Subjects are able to perform continuously for 14-18h before significant decrements begin to appear in their performance. The time course of recovery varies according to the duration of the continuous work period, the amount of subsequent sleep and the disturbance of the circadian rhythm.
