Sleep Architecture

  • Total and partial deprivation are different manipulations with different effect sizes.

    Sleep loss is not a single exposure. Total deprivation significantly impaired accuracy across sensory, working and permanent memory tasks, whereas partial deprivation produced subtler effects — roughly a 5.3% accuracy drop on the auditory task and 5.4% more response failures.

  • Which measure you take determines which countermeasure appears to work.

    Countermeasures act on different outcomes rather than substituting for one another. Caffeine improved simple reaction time while a nap improved two-choice reaction time; after a normal night only the nap improved mood. Separately, 30 minutes of moderate cycling reversed sleep-deprivation impairments on a Go/NoGo task, raising accuracy by up to 9.51%.

  • Scope / different questions

    Whether sleep loss impairs cognition depends on the population and the outcome, and these studies do not share either. Total deprivation degraded accuracy in young adults across three memory tasks, while in older adults a night of total deprivation left working-memory accuracy, speed and the positivity bias unchanged on a brief task.

Memory Consolidation

  • Scope / different questions

    How much sleep loss is needed before consolidation suffers is not settled by these studies, because they used different doses and different measures. Total deprivation impaired accuracy across sensory, working and permanent memory tasks, whereas partial deprivation produced subtler effects — about a 5.3% accuracy drop on the auditory task and 5.4% more response failures.

State Anxiety

  • Sleep deprivation for 24 hours significantly increases immediate state anxiety, which is accompanied by physiological changes in brain wave patterns.

Cox Proportional Hazards Model

  • In observational cancer and sleep cohorts, Cox models turn deprivation, education and disease severity into excess-hazard or event-rate contrasts. ONS Longitudinal Study analyses found less-deprived areas had lower excess hazard for prostate cancer (EHR 0.80) and that absolute net-survival gaps between extreme individual SES profiles were 29.6% in the most deprived areas versus 9.1% in the least; an OSA sleep-lab cohort of 10,149 patients had 11.5% composite events over a median 68 months, with higher AHI linked to higher hazard (e.g. univariate HR 1.49 for high versus low AHI).
