How sleep duration and quality affect cognitive performance, decision-making, and economic productivity — the neuroscience and economics of sleep deprivation. Built on Walker, Dinges, Gibson & Shrader, Hafner et al. Data from ATUS (American Time Use Survey, 200K+ respondents), NHANES sleep modules, Fitbit/wearable population studies, and natural experiments using daylight saving time shifts. The most data-rich domain nobody packages: sleep is measured at population scale but rarely linked to economic outcomes.
Chronic sleep restriction to 6 hours/night for 14 consecutive days produces cognitive impairment equivalent to 2 nights of total sleep deprivation, as measured by PVT lapses. Critically, subjects report feeling only 'slightly sleepy' while their objective performance has degraded catastrophically. Subjective adaptation is an illusion.
Insufficient sleep costs the US economy $411 billion annually (2.28% of GDP) through mortality, absenteeism, and presenteeism. If individuals sleeping less than 6 hours started sleeping 6-7 hours, it would add $226.4 billion to the US economy. The relationship between sleep and productivity is strongly non-linear — going from 5 to 6 hours matters far more than 7 to 8.
One additional hour of sleep per night increases wages by 4.9%. Using sunset-driven variation in sleep timing as an instrument (earlier sunset = more sleep), the causal effect of sleep on productivity is positive and economically significant. Located on the western edge of a time zone (where sun sets later) reduces sleep by 19 minutes and annual earnings by ~$1,300.
Domain: Sleep, Cognition & Economic Productivity
Interdisciplinary study linking sleep duration and quality to cognitive performance, workplace productivity, and macroeconomic outcomes. Bridges neuroscience (memory consolidation, prefrontal function), occupational health (accident risk, absenteeism), and economics (GDP impact of insufficient sleep). Unique because individual-level sleep data exists at massive scale (wearables, time-use surveys) but cross-domain synthesis is rare.

The Monday after spring DST transition (1 hour lost) shows 5.7% more workplace injuries and 67.6% greater severity (lost work days). The autumn gain-an-hour transition shows no compensating decrease. This natural experiment demonstrates that even a single hour of population-level sleep loss has immediate, measurable safety consequences.
Sleep deprivation impairs prefrontal cortex function disproportionately, degrading executive function, emotional regulation, and moral reasoning before basic cognitive processes. A sleep-deprived individual performs like someone with prefrontal damage: intact procedural abilities but impaired judgment, creativity, and social cognition.
A planned 26-minute cockpit nap improved pilot subsequent performance by 34% (PVT) and alertness by 54% (EEG). The nap group made zero micro-sleep events during the critical descent/landing phase; the no-nap group averaged 22 micro-sleeps. This NASA study established that brief naps are a countermeasure, not a sign of laziness.
