What is a common symptom of dehydration?

A common symptom of dehydration is dry, cool skin. When the body loses more fluids than it takes in, it can lead to a decreased ability to maintain moisture in the skin, resulting in a dry appearance. This occurs because the body prioritizes hydration for vital organs, diverting water away from the skin. Affected individuals may also experience decreased sweating, which further contributes to the dryness. Identifying this symptom is essential as it can help in recognizing dehydration early, allowing for timely intervention and rehydration.

The other symptoms presented typically do not align with the condition of dehydration, making dry, cool skin a clear indicator. Increased urination, for instance, is often associated with adequate hydration or excessive fluid intake, while enhanced appetite might suggest a state of nutritional adequacy rather than dehydration. Swollen limbs could be indicative of fluid retention or other medical conditions but are not characteristic of dehydration.
