HYPOHYDRATION AND THERMOREGULATION IN COLD AIR

This study examined the effects of hypohydration on thermoregulation during cold exposure. In addition, the independent influences of hypohydration-associated hypertonicity and hypovolemia were investigated. Nine male volunteers were monitored for 30 min at 25 degrees C, then for 120 min at 7 degrees C, under three counterbalanced conditions: euhydration (Eu), hypertonic hypohydration (HH), and isotonic [...]

DISTRIBUTION OF WATER LOSSES AMONG FLUID COMPARTMENTS OF TISSUES UNDER THERMAL DEHYDRATION IN THE RAT

Dehydration amounting to about 10% of body weight was induced in adult male rats by exposure to a hot, dry environment (D.B.T., 36 degrees C; R.H., 20%) over 6 to 8 hr. The volumes of total water (TW), extracellular fluid (ECF), and plasma (PV) were determined both on individual tissues and on the whole body [...]

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 [...]
