Dr. Karan Rajan, a surgeon from the UK, emphasizes that clear urine is not a sign of good health but rather a potential indicator of overhydration. He explains that urine should have a slight yellow color due to urochrome, a compound from hemoglobin breakdown. When overhydrated, the kidneys excrete excess water, diluting necessary electrolytes. Dr. Rajan advises that urine color alone is insufficient for assessing hydration, as it reflects past hydration status. He recommends monitoring additional markers such as urination frequency (four to six times daily), energy levels, mucous membrane condition, and resting heart rate to gauge hydration more accurately. This information serves as a guideline for maintaining optimal hydration and overall health.
