How can sleep debt be paid off?

• A. By drinking coffee
• B. It can only be paid off by sleeping
• C. By taking short naps during the day
• D. By exercising vigorously

Answer: (B)

Sleep debt is paid off by getting more sleep. When you miss sleep, a deficit builds up that can’t be fully erased by a single long nap or by caffeine; your body needs actual, extended sleep to restore cognitive performance, mood, and physical functioning. Short naps can help with immediate alertness but don’t completely repay the debt if you’re chronically underslept. Vigorous exercise doesn’t replace sleep and late workouts can even make it harder to sleep well. So the most effective way to repay sleep debt is to get extra, regular sleep until you’re back to an adequate sleep level.
