Sleep readiness directs Soldiers on the proper dosing and techniques for maintaining the health of which part of the body?

• A. Heart
• B. Lungs
• C. Liver
• D. Brain

Answer: (D)

Sleep readiness focuses on preserving brain health because sleep directly governs cognitive function, memory, mood, reaction time, and decision-making. During sleep, the brain processes daily information, consolidates learning, and clears metabolic waste through systems like the glymphatic pathway, helping maintain neural integrity. Getting enough sleep at consistent times, along with practical techniques—such as a regular sleep schedule, a cool dark environment, limited late-day caffeine, and strategic napping when needed—supports these brain processes. While sleep affects the whole body, the target of sleep readiness practices is the brain, which underpins performance and resilience for Soldiers.
