TAP reading note: The cumulative cost of additional wakefulness: dose-response effects on neurobehavioral functions and sleep physiology from chronic sleep restriction and total sleep deprivation

What the study found

Repeated sleep restriction produced cumulative cognitive performance deficits that subjective sleepiness did not fully track.

Scope & limitations

48 healthy adults aged 21–38; experiments included 14 nights of restricted time in bed

Laboratory sleep restriction does not define everyone’s recovery timeline or a universal recovery debt.

Population & sample

48 healthy adults aged 21–38; experiments included 14 nights of restricted time in bed

Exposure or intervention

Outcomes

Cognitive performance, subjective sleepiness and sleep physiology

Time frame

14 nights of restriction or 3 nights without sleep; 3 baseline and 3 recovery days in each experiment
