Which statement describes a primary sign of dehydration during a paddle trip?

• A. Bright yellow urine
• B. Headache only
• C. Nausea only
• D. Dark urine, fatigue

Answer: (D)

Staying hydrated during a paddle trip is essential because sweating and sun exposure quickly remove fluids. The most reliable sign of dehydration is dark urine paired with fatigue. Dark urine means the body is conserving water and producing concentrated waste, while fatigue shows the body's cells are not getting enough water and electrolytes, which can sap energy and focus during activity. The other options don’t fit as well: bright yellow urine can occur with certain vitamins or recent fluid intake and isn’t a definitive dehydration signal; a headache can happen for many reasons and isn’t as specific to hydration status; nausea alone can arise from motion, heat, or other factors. If you notice dark urine and feel tired, take a break, drink fluids with electrolytes, and rest in the shade.
