Which statement about energy drinks and fatigue is most accurate?
- A.They reset the need for sleep for 8 hours
- B.They are banned for all drivers
- C.They can briefly raise alertness but do not replace sleep, and the effect fades while sleep pressure keeps building
- D.They improve reaction time more than a nap
Correct answer
C. They can briefly raise alertness but do not replace sleep, and the effect fades while sleep pressure keeps building
Why
Caffeine-based drinks mask one symptom, sleepiness, for a short window, but they do not restore judgment, memory, or reaction time the way sleep does. Planning rest remains the only dependable strategy on a long run.
