Void frequency (VF) is significantly correlated to hydration status, but it is unknown whether VF is reliable when an individual is repeatedly euhydrated (EU) or hypohydrated (HY). The purpose of this ...

Few user-friendly hydration assessment techniques exist for the general population to use on a daily basis. The present study evaluated void number over 24 h as a potential hydration assessment tool.

LISBON, Portugal — Volume overload measured using a novel technique known as bioelectrical impedance vector analysis, which allows researchers to quantify hydration status, was significantly ...

Dehydration can be dangerous for the elderly, since their thirst mechanisms and kidneys may not be as well tuned in to the body's status as compared to those of younger people. But the current urine ...

Background Hydration status is one measure used to determine risk of heat illness, such as heat stroke. The most common assessment used is urine specific gravity. However, this test presents inherent ...
