Sleep Debt FAQ
What is sleep debt?
Sleep debt is the cumulative effect of not getting enough sleep. It's the difference between the amount of sleep you need and the amount you actually get. Just like financial debt, it keeps adding up over time.
How much sleep do adults need?
Most adults need 7-9 hours of sleep per night. The National Sleep Foundation recommends 7-9 hours for adults aged 18-64, and 7-8 hours for those 65 and older.
Can you recover from sleep debt?
Yes, but it takes time! Short-term sleep debt (a few days) can be recovered within a few days of extra sleep. However, chronic sleep debt may take weeks of consistent, quality sleep to fully recover from.
What are the effects of sleep debt?
Sleep debt can affect cognitive function, mood, immune system, and overall health. It's linked to increased risk of obesity, diabetes, cardiovascular disease, and decreased productivity and creativity.
