What is a primary sign of dehydration?

• A. Dark urine, fatigue
• B. Frequent urination
• C. Hunger
• D. Sneezing

Answer: (A)

A primary sign of dehydration is dark urine along with fatigue. When you don’t have enough fluids, your kidneys conserve water, concentrating urine and making it look dark. Fatigue follows as reduced blood volume and electrolyte imbalance limit your body’s ability to deliver oxygen and energy where it’s needed. In paddling situations, this combination warns you to stop to hydrate and rest if needed. Other options don’t fit dehydration: frequent urination isn’t typical when you’re dehydrated (it usually decreases), hunger relates to energy intake, and sneezing isn’t connected to hydration status.
