What is sleep debt?

Sleep debt is a cumulative shortfall in the amount of rest your body needs to function at its best. Whether you’re staying up late, waking frequently, or just not sleeping long enough, the lost hours don’t simply disappear - they build up, leading to fatigue, reduced focus, lower immunity, and even long-term health risks.

Most adults need around 7 to 9 hours of sleep per night. If you regularly fall short, this calculator can help you estimate how much sleep debt you've accumulated over the past seven days - and what you can do to recover. While you can’t always repay every lost hour, improving your sleep habits and prioritising rest can make a big difference to how you feel day to day.
