Frequently Asked Questions

What is the sleep target?
WHO and AASM (American Academy of Sleep Medicine) 2024: 7-9 hours/night for adults. Most adults need 7.5-8 hours for cognitive optimum and disease-risk minimum. Genetic short sleepers (need 6h) are <3% of population — most who think they're short sleepers are accumulating debt.
Can sleep debt be repaid?
Acute (week-old) debt: yes, with 2-3 nights of 9-hour sleep. Chronic (months/years) debt: cognitive deficits show partial recovery in 1-2 weeks of consistent good sleep, but some markers (e.g. amyloid clearance, glymphatic function) recover slowly. The lifetime risk effects on dementia, cardiovascular disease, metabolic health are partially permanent for chronically deprived sleepers.
Why does this matter long-term?
Chronic sleep deprivation (<6h/night for years) is associated with: 30% higher Alzheimer's risk, 45% higher heart attack risk, 40% higher cancer risk, depressed immune function, weight gain, mood disorders. Walker (2017) "Why We Sleep" summarizes the science. The cost compounds.
How do I close the gap?
Five concrete moves: (1) Hard bedtime alarm 9 hours before wake. (2) Cool bedroom (18°C). (3) Nee screens 30 min before. (4) Caffeine cutoff at 2pm. (5) Same wake time every day, including weekends. Do all 5 for 21 days — most chronic short-sleepers reclaim 1+ hour with no effort.
