What is the Sleep Debt Calculator?
Sleep debt is the difference between the sleep you need and the sleep you actually get. Missing just one hour a night adds up to a full night lost every week – affecting focus, mood and health. Choose your age group (or your own goal), enter last week’s hours and see your debt plus a gentle plan to recover.
