What is a key strategy to prevent acute fatigue?

• A. Engaging in regular exercise
• B. Eating well and maintaining energy throughout the day
• C. Drinking caffeinated beverages
• D. Taking frequent short breaks

Answer: (B)

Maintaining energy throughout the day through proper nutrition is essential in preventing acute fatigue. Eating well provides the body with the necessary nutrients and energy it needs to function optimally. A balanced diet contributes to stable blood sugar levels, which helps in sustaining energy levels throughout the day, reducing the risk of fatigue that often leads to decreased performance and increased errors in a high-stakes environment such as aviation.

Regular exercise can also play a role in managing fatigue, as it improves overall physical health and endurance, but its primary benefits are seen over a longer term rather than as an immediate solution. Drinking caffeinated beverages may offer a temporary boost in alertness, but reliance on caffeine can lead to a crash later, contributing to fatigue rather than preventing it. While taking frequent short breaks can help relieve mental and physical strain, it is the consistent maintenance of energy through nutrition that forms the foundation for sustained performance and fatigue management.
