In deployment, how should hydration be treated in the nutrition plan?

• A. Hydration is not important.
• B. Hydration is optional if calories are met.
• C. Hydration should be prioritized alongside calories and macros, with adjustments for activity and environment.
• D. Hydration only matters on rest days.

Answer: (C)

Hydration is essential because it supports blood volume, thermoregulation, digestion, and cognitive function, all of which are critical for performance in deployment. In hot or physically demanding environments, fluid and electrolyte losses from sweat can be substantial, so not addressing hydration can limit endurance and increase the risk of heat illness even if calories and macros are correct. Therefore hydration should be integrated with the nutrition plan, with adjustments for activity level, sweat rate, gear, and environmental conditions. Start well hydrated, sip fluids before and during activity, replenish electrolytes for longer workouts, and rehydrate afterward; monitor urine color and weight changes to guide intake. Hydration matters every day, not only on rest days.
