How does urine color relate to hydration status?

Darker urine typically indicates dehydration because as the body becomes dehydrated, it conserves water, leading to more concentrated urine, which appears darker in color. On the other hand, when a person is adequately hydrated, the urine becomes more diluted, resulting in a lighter color. Therefore, observing the color of urine can serve as a quick and practical visual indicator of an individual's hydration status.

Other options do not accurately represent the relationship between urine color and hydration. For instance, stating that color has no correlation to hydration overlooks the established link that urine color provides clear feedback on hydration levels. Similarly, claiming that lighter urine indicates dehydration contradicts the physiological understanding of urine concentration, as lighter urine actually reflects a higher fluid level in the body. Lastly, suggesting that red urine indicates overhydration is misleading, as red urine is more commonly associated with the presence of blood or other substances rather than hydration levels.
