What color urine is strongly associated with dehydration?

Dark-colored urine is strongly associated with dehydration because it indicates a higher concentration of waste products and less diluted urine. When the body is dehydrated, it retains water, leading to more concentrated urine that has a darker hue. In contrast, well-hydrated individuals typically have urine that is pale yellow or clear, indicating optimal hydration levels and dilution of waste products. Light amber urine may also suggest mild dehydration, but dark-colored urine more distinctly signals a need for increased fluid intake to restore hydration status. Understanding this relationship is essential for recognizing hydration needs and is a fundamental aspect of sports nutrition coaching.
