INFLUENCE OF HYDRATION STATUS AND FLUID REPLACEMENT ON HEAT TOLERANCE WHILE WEARING NBC PROTECTIVE CLOTHING.
The purpose of the present study was to investigate the influence of hypohydration and fluid replacement on tolerance to an uncompensable heat stress. Eight healthy young males completed a matrix of six trials in an environmental chamber, set at 40 degrees C and 30% relative humidity, while wearing nuclear, biological, and chemical protective clothing. Subjects [...]
HYDRATION AT THE WORK SITE.
When performing physical work, sweat output often exceeds water intake, producing a body water deficit or dehydration. Specific to the work place, dehydration can adversely affect worker productivity, safety, and morale. Legislative bodies in North America such as the Occupational Safety and Health Administration (OSHA) and the American Conference of Governmental Industrial Hygienists (ACGIH) recommend [...]

WATER INTAKE AND URINARY VOLUME DURING 20 DAYS BED-REST IN YOUNG WOMEN.
During the bed-rest in the young subjects, the water intake should be depressed, because the diuretic is probably accelerated, and then the total body water and body weight is decreased by the water loss. In our previous study in 1991, we have reported that urinary volume was gradually increased, while water intake was decreased. Therefore, [...]
URINARY AND HEMATOLOGIC INDEXES OF HYPOHYDRATION.
As part of a large-scale field feeding system test we were able to collect and study hundreds of aliquots of overnight urine samples obtained immediately prior to a fasting blood sample on days 1, 20, and 44 of the field test. The large number of experimental samples (greater than 650) and concomitant collection of blood [...]
THIRST AND FLUID INTAKE FOLLOWING GRADED HYPOHYDRATION LEVELS IN HUMANS.
The relationship among changes in thirst sensations, blood variables, and differential fluid intake in hypohydrated humans was examined. Seven subjects were hypohydrated by 0%, 3%, 5%, and 7% of their body weight on four separate trials which were systematically randomized between subjects. Hypohydration levels were achieved with a regimen of restricted food and fluid intake [...]

REDUCED THIRST AFTER WATER DEPRIVATION IN HEALTHY ELDERLY MEN.
To determine whether responses to dehydration are altered with age, we investigated the thirst, fluid and electrolyte responses, and hormonal responses to 24 hours of water deprivation in seven healthy active elderly men (67 to 75 years old) and seven healthy young men (20 to 31 years old) who were matched for weight loss during [...]
EFFECTS OF HYDRATION ON FEBRILE TEMPERATURE PATTERNS IN RABBITS
Patients with fever have a predisposition to experience dehydration, which may alter their thermoregulatory responses to elevated body temperature. In view of the recent discovery of the antipyretic activity of arginine vasopressin (AVP), it is possible that dehydration has a beneficial role during fever. Dehydration may enhance endogenous antipyresis by stimulating AVP release, making aggressive [...]
