FAQ
What is sleep debt and how does it affect me?
Sleep debt is cumulative hours of sleep you're behind. Missing 30 min/night = 3.5 hours/week debt. Effects: impaired memory, slower reaction times, weakened immune system, irritability, weight gain. Chronic debt linked to heart disease, diabetes, depression. Unlike financial debt, you can't fully "repay" in one weekend.
How long does it take to recover from sleep debt?
Depends on severity. Minor debt (< 10 hours): recover in 2-3 days with extra sleep. Moderate (10-20 hours): 1-2 weeks. Severe (20+ hours): multiple weeks of consistent good sleep. Add 1-2 hours per night above your need. Your body will naturally catch up, then return to normal schedule.
Can I really catch up on sleep during weekends?
Partially, but not completely. Sleeping 2-3 extra hours on weekends helps reduce debt and improves alertness, but doesn't fully restore cognitive function or metabolic health. Better strategy: consistent 7-9 hours every night. "Social jet lag" (inconsistent sleep schedule) is unhealthy long-term.
