Sleep debt and daytime performance nuance?

• A. Sleep debt accumulates over days and may impair cognitive and motor performance; short-term sleep may help but not fully recover
• B. Sleep debt always improves performance
• C. Sleep debt has no effect on mood
• D. Sleep debt is recovered instantly

Answer: (A)

Sleep debt builds up when you don’t get enough sleep, and this deficit tends to accumulate over days. That accumulated lack can blunt daytime performance, especially on tasks that require sustained attention, quick reaction times, and precise motor control. When you finally catch up with extra sleep, the improvement is typically partial—a short period of sleep can boost alertness and accuracy, but it doesn’t erase all the lost performance from the earlier nights. Mood is also often affected, with more fatigue, irritability, and reduced motivation. Recovery usually needs more than one night of sleep; several nights of adequate sleep are often required to bring performance back toward baseline. The other statements don’t fit this pattern: sleep debt does not automatically improve performance, it can alter mood, and it isn’t recovered instantly.
