Sleep Debt Calculator

• Your average of 6.8 h/night is 1.2 h below the NSF recommendation of 8 h for adults (18-60).
• Expect roughly 14 days of consistently longer nights to clear it. Sleep debt does not repay hour-for-hour, and oversleeping on a single weekend day helps but does not erase a full week of deficit.
• At this level of debt, cognitive performance can match 48 hours of total sleep deprivation, and microsleep episodes become a real safety risk while driving or operating machinery.

Next stepSee a doctor if you struggle to sleep despite adequate time in bed - chronic debt may signal an underlying disorder such as sleep apnea.
