Abstract:

Sleep loss leads to profound performance decrements. But many individuals believe they adapt to chronic sleep loss or that recovery requires only a single extended sleep episode. Several protocols with non 24-hour sleep/wake T-cycles were designed so that these sleep and wake episodes were distributed across all circadian phases, enabling measurement of the effects of acute and chronic sleep loss at different times of the circadian day and night. Modern statistical methods were used to study the structure of sleep and the effect of sleep loss. The results suggest that chronic sleep loss markedly increased the rate of deterioration in performance across wakefulness, particularly during the circadian “night.” Thus, extended wake during the circadian night reveals the cumulative detrimental effects of chronic sleep loss on performance, with potential adverse health and safety consequences.
