How can fatigue affect performance, and what measures support fatigue management?

• A. It impairs judgment and slows reaction time; schedule design, breaks, nap opportunities, and workload balancing help.
• B. It improves endurance; longer shifts reduce errors.
• C. It only affects physical tasks, not cognitive tasks.
• D. Fatigue management is unnecessary if you drink coffee.

Answer: (A)

Fatigue dulls alertness, slows reaction time, and impairs judgment, which can lead to slower decision-making, missed cues, and more errors across both physical and cognitive tasks. To manage fatigue effectively, focus on system-level measures that support recovery and safe performance: thoughtful schedule design that avoids overly long shifts and provides adequate rest between shifts; regular breaks and, where feasible, nap opportunities to reduce accumulating sleep debt; and balancing workload so demanding tasks aren’t clustered when fatigue is likely to be highest. Creating an environment that supports recovery—such as quiet rest areas, appropriate light exposure, and attention to cumulative workload—also helps. Caffeine can help temporarily but is not a substitute for proper rest or comprehensive fatigue management.
