The Role of Hydration on Peripheral Response to Cold

Abstract

Ten men were dehydrated by restriction of fluid intake and by exercise over 2-1/2 days (weight loss: 4.6%), Body weight returned to -1.6% within 10 hours after rehydration, suggesting the weight loss was fluid loss. Measures of blood and urine constituents also were indicative of dehydration. These subjects experienced a cold test prior to and after dehydration and after rehydration. The fingers, but not the back of the hand, of the dehydration group were significantly colder (P<0.5) following dehydration. A group of 10 control subjects tested under identical conditions, but hydrated at all times, showed no changes.
