What is described as the only thing that can overcome fatigue?

• A. Sleep
• B. Caffeine
• C. Exercise
• D. A hot meal

Answer: (A)

Fatigue is best overcome by sleep because only sleep fully restores the body's energy systems and resets brain function. While caffeine can wake you up briefly by stimulating the nervous system, it doesn’t remove the underlying need for rest, and its effects wear off, leaving you just as fatigued. Exercise can help you feel more alert for a short period, but it doesn’t erase sleep debt. A hot meal can even slow you down afterward as digestion diverts blood flow and can cause tiredness. So, sleep is the only lasting solution to fatigue.
