TL;DR.<\/strong> Sleep debt is real, measurable and only partly repayable. In the 2024 National Health Interview Survey, 30.5% of US adults slept less than 7 hours a day (NCHS, 2026). In the best-known lab experiment on chronic restriction, 14 nights of 6 hours or less in bed produced cognitive deficits equal to up to 2 nights of total sleep deprivation, and participants’ own sleepiness ratings barely registered the decline (Van Dongen et al., 2003). Repayment is uneven. One night of up to 10 hours in bed after 5 nights of 4 hours left attention, sleepiness and fatigue incomplete (Banks et al., 2010). Three nights of 8 hours did not restore vigilance in people who had spent a week at 5 or 7 hours in bed (Belenky et al., 2003). A free weekend did not protect insulin sensitivity once short nights resumed (Depner et al., 2019). The picture is not all bad: in a Swedish cohort of 43,880 people, adults under 65 who slept short on weekdays but long on weekends had mortality no different from consistent 6-7 hour sleepers (\u00c5kerstedt et al., 2019). Below is a four-step self-audit to estimate your own debt and a table of what recovers and what does not.<\/p>\n
