How much water should you drink during extended operations?

• A. 8-12 ounces
• B. 4-6 ounces
• C. 16-20 ounces
• D. 24 ounces

Answer: (A)

Keeping hydrated during extended operations is about regular, modest fluid intake that matches sweating without overloading the stomach. The best practice is to sip water in manageable amounts—about eight to twelve ounces—every 15 to 20 minutes. This pace helps replace fluid losses from sweat, supports steady performance, and minimizes stomach discomfort that can come from larger boluses. Drinking larger amounts at once, like 16–20 or 24 ounces, can cause fullness, slower absorption, and GI issues that slow you down. Conversely, taking only 4–6 ounces may not keep up with ongoing losses, increasing the risk of dehydration over long tasks. In hot or high-intensity conditions, pairing water with electrolytes can help maintain balance, and adjust the plan based on individual needs and PPE strain.
