Frequently Asked Questions
What is sleep debt?
Sleep debt is the cumulative effect of not getting enough sleep. If you need 8 hours but only sleep 6, you accumulate 2 hours of sleep debt per night. This debt affects cognitive function, mood, and health.
Can you 'catch up' on sleep?
Yes, but it takes time. You can recover about 1-2 hours of sleep debt per night by sleeping longer. However, chronic sleep deprivation may have lasting effects that aren't fully reversible.
How much sleep do I need?
Most adults need 7-9 hours per night. The ideal amount varies by individual—some people function well on 7 hours, others need 9. Pay attention to how you feel when waking naturally.
Why does screen time affect sleep?
Blue light from screens suppresses melatonin production, making it harder to fall asleep. Aim to stop screen use 1-2 hours before bed, or use night mode/blue light filters.
