Based on National Sleep Foundation guidelinesThe Science of Sleep Debt
Cognitive Impact

Cardiovascular Risk
Chronic sleep debt increases heart disease risk by 48% and stroke risk by 15%, according to European Heart Journal.
Weight Gain
Sleep debt disrupts leptin and ghrelin hormones, increasing appetite by 25% and craving for high-calorie foods by 33%.
Science-Backed Recovery Strategies
Week 1: Sleep Extension
Add 30-60 minutes to your nightly sleep. Don't try to "sleep in" on weekends - consistency is key for circadian rhythm regulation.
Week 2: Sleep Schedule
Go to bed and wake up at the same time every day, even weekends. This stabilizes your internal clock and improves sleep efficiency.
Week 3: Maintenance
Recalculate your debt. If cleared, maintain your new schedule. If not, continue extension for another week before reassessing.
