Understanding Sleep Debt
The Science of Sleep Debt
Accumulation
Sleep debt builds over days and weeks. Missing 1 hour nightly adds up to about 7 hours of shortfall per week, and research shows these deficits keep accumulating rather than leveling off.
Performance Impact
In controlled studies, two weeks of 6 hours in bed per night impaired attention as much as a full night without sleep, and the decline kept growing over time (Van Dongen et al., 2003).
