Sleep Debt: Sleep debt is the cumulative gap between the sleep you need and the sleep you actually get. If you need 8 hours but average 6.5, you accrue 1.5 hours of debt each night — about 10.5 hours per week. Clinarix totals your weekly debt and prescribes how to repay it without disrupting your circadian rhythm.

ƒWeekly sleep debt = (ideal hours − actual hours) × 7 nights · repay ≈ +1 h/night over several nights

How the Sleep Debt works

How is sleep debt calculated?

We subtract your average nightly sleep from your individual sleep need (default 8 hours) and multiply by seven to express the weekly deficit. Recovery is then spread across several nights rather than one long catch-up sleep.
