You get lost and find yourself in survival mode. Your priorities are shelter, fire, and:

• A. Water
• B. Food
• C. Navigation
• D. Signaling

Answer: (A)

Hydration is the immediate need after shelter and fire. The body relies on water for every system—circulation, temperature regulation, waste removal, and brain function. When you’re short on fluids, you’ll become weak, dizzy, and mentally foggy, which can lead to dangerous mistakes in a survival situation. Because dehydration can set in within a few days, while you can go much longer without food, water has to come first.

Seek and secure safe water sources, and treat it if you’re unsure about contamination. You can obtain water from streams, rain, melted snow, or condensation, and use boiling or filtration to make it safe. Foods can wait longer, and while signaling or navigation are important for rescue and safety, you won’t be able to effectively pursue them if you’re dehydrated.
