Which of the following is NOT a symptom of dehydration?

Clear urine is indeed not a symptom of dehydration. In fact, clear urine typically indicates adequate hydration levels in the body. When the body is well-hydrated, urine tends to be light in color, often ranging from pale yellow to clear. This is a sign that the kidneys are effectively flushing out excess water and waste.

On the other hand, symptoms like headache and dizziness are commonly associated with dehydration. As the body loses more fluids than it takes in, it can lead to a decrease in blood volume, which may cause feelings of dizziness and headaches due to reduced oxygen and nutrient delivery to the brain, as well as increased pressure on the nervous system.

Dark urine, conversely, is another symptom of dehydration. When the body is dehydrated, urine becomes concentrated and darker in color, signaling that the body is retaining water and that there may be insufficient fluid intake. Therefore, recognizing clear urine as a sign of adequate hydration is crucial in understanding fluid balance and the prevention of dehydration.
