Frequently Asked Questions — Sleep Debt Calculator
How does weekly sleep debt affect performance?+
Every 1 hour of nightly sleep debt impairs performance by approximately 25% after a week. Teams operating with chronic weekly deficits are effectively working at 50-60% cognitive capacity — affecting problem-solving, creativity, and risk management.
Is it possible to catch up on sleep over the weekend?+
Yes, but imperfectly. Cognitive recovery is partial after 2 nights of extended sleep. You can clear most short-term debt but not chronic debt. Also, sleeping in on weekends by 2+ hours causes social jet lag — your Monday cognitive function suffers despite the extra sleep.
How much extra sleep do I need to recover from weekly sleep debt?+
For every hour of nightly debt over a week, add approximately 45-60 minutes of extra sleep per night for 4-5 nights. Total debt of 7 hours (losing 1h/night): ~5 nights of +90min. Consistency matters more than length on any single night.
