Frequently Asked Questions
What is sleep debt?
Sleep debt is the cumulative difference between the amount of sleep you need and the amount you actually get. If you need 8 hours but sleep 6, you accumulate 2 hours of sleep debt per night.
How long does it take to recover from sleep debt?
Research suggests it takes about 4 days to recover from each hour of sleep debt. Recovery should be gradual - adding 15-30 extra minutes per night rather than sleeping excessively on weekends.
