How is hydration measured?
This question has been investigated through many research projects and clinical trials. At Stayhealthy we reviewed a number of published works on the subject and even conducted our own clinical trial. The broad range of answers we found were inconsistent and confusing. What was clear, however, was the need for a better way to report hydration results. So we have developed the Stayhealthy Hydration Index (SHI), which calculates on an individual basis, your specific hydration status based on broad population averages and studies.
