Sleep debt is the cumulative effect of insufficient sleep. Each hour of sleep deficit impairs cognitive performance, mood, and physical health. The brain does not fully "forget" sleep debt — it accumulates across weeks.
ステップバイステップガイド
- 1Sleep debt per night = Required sleep − Actual sleep
- 2Cumulative debt = Σ daily deficits
- 3Full recovery requires extra sleep (beyond normal hours) on multiple nights
- 4Cognitive impairment from 6 vs 8 hours is similar to 24-hour total sleep deprivation after 10 days
