Sleep debt is the cumulative effect of consistently getting less sleep than your body needs.
Miss an hour a night for five nights and you’ve built up five hours of sleep debt by the weekend. Research suggests that while you can partially recover from short-term sleep debt, the cognitive effects — slower reaction time, reduced focus, impaired decision-making — don’t fully resolve with a single night of catch-up sleep.
What most people don’t know: sleep debt can accumulate even when you’re technically sleeping enough hours.
If your sleep is being interrupted repeatedly — as happens with sleep apnea — you can be in a state of chronic sleep debt without realizing it. You’re clocking eight hours.
You’re just not getting eight hours of restorative sleep.
This is why so many people with undiagnosed sleep apnea describe feeling perpetually behind, no matter how early they go to bed.
