HYDRATION EFFECTS ON COGNITIVE PERFORMANCE DURING MILITARY TASKS IN TEMPERATE AND COLD ENVIRONMENTS.

Body water deficits or hypohydration (HYP) may degrade cognitive performance during heat exposure and perhaps temperate conditions. Cold exposure often induces HYP, but the combined effects of cold and HYP on cognitive performance are unknown. This study investigated whether HYP degrades cognitive performance during cold exposure and if physical exercise could mitigate any cold-induced performance [...]

SIMULTANEOUS DETERMINATION OF FLUID SHIFTS DURING THERMAL STRESS IN A SMALL-ANIMAL MODEL.

We have developed methodology to simultaneously measure fluid redistribution among the major compartments during moderate and severe hypohydration. Total body water (TBW) was determined using tritiated water, extracellular fluid volume (ECF) was measured using a single-injection [14C]inulin technique, and plasma volume (PV) was determined by indocyanine green dye dilution. Moderate (10% decrease in body wt) [...]

PREVENTING DEHYDRATION IN CHILDREN WITH CYSTIC FIBROSIS WHO EXERCISE IN THE HEAT.

PURPOSE: In healthy children who exercise in the heat, the addition of flavor, carbohydrate, and 18 mmol x L(-1) NaCl to water induced a major increase in voluntary drink intake compared with the intake of unflavored water. This increase was sufficient to prevent voluntary dehydration. We hypothesized that, to achieve a similar effect in children [...]

IMPROVED THERMOREGULATION CAUSED BY FORCED WATER INTAKE IN HUMAN DESERT DWELLERS.

Residents of the Negev desert in Israel sustain a mild state of dehydration. Low, concentrated urine outputs, high incidence of kidney diseases and high hematocrit ratios characterize this population. Educational programs to increase the awareness of the population to the dangers of dehydration have undoubtedly failed. It was our purpose to see whether forced increased [...]

ENVIRONMENTAL AND NUTRITIONAL FACTORS SIGNIFICANTLY ASSOCIATED WITH CANCER OF THE URINARY TRACT AMONG DIFFERENT ETHNIC GROUPS.

A high incidence rate of urinary tract cancer in the Acre District among the Jewish population compared with the non-Jewish population has been studied. The dietary and environmental factors identified and the possible mechanisms of the protective effect that may be conferred by fluid intake, olives and olive oil, cumin, and pepper (chili pepper and [...]
