Overhydration

Body water is tightly regulated to ensure we have just enough, and varies by no more than 1% daily in normal, healthy people (around 250-500ml). When body water decreases (e.g. due to sweating) or blood sodium levels rise, thirst is stimulated and the kidneys conserve fluid. Most people respond by drinking slightly more but, in a small […]

Measuring hydration status

Evaluation of hydration status is not easy, as during daily activities or exercise, fluid compartments are constantly fluctuating, so measuring a single body fluid is insufficient to provide valid information about total body water. In this new issue we present some of the methods used to measure hydration status and focus on those that are simple easy to perform […]
