Hypohydration and Mood State in Free-Living Males and Females
… loss in total body water. However, the effect of hypohydration (i.e., reflected through high urine concentration) on mood in free-living conditions has not been studied. PURPOSE: The present study was designed to determine if hydration status is associated with mood within the general population …

Haemodynamic responses to heat stress and hypohydration in resting and exercising humans: Implications for the regulation of skeletal muscle blood flow
… stress-induced hyperthermia and exercise-induced hypohydration are associated with marked alterations in limb and systemic haemodynamics in humans. However, the mechanisms underlying these alterations their effects on muscle blood flow are not well understood. The present thesis examined whether …

The Association of Fluid Intake With Total Natural-cause Mortality, Coronary Heart Disease and Fatal Stroke
<p>Hypohydration may be more widespread than realized since it does not always arouse a sense of thirst. When thirst is felt, it is often ignored, or satisfied before euhydration is achieved. There is growing evidence indicating that hypohydration contributes to acute and chronic illnesses, and to …

Selected physiological and perceptual responses of males during prolonged exercise
… 50% RH/hydration (HH), and hot (35°, 50% RH/hypohydration (HP). Perceptual responses were determined by Borg's 10-point category ratio scale ( 1980) and by a multi-dimensional symptom scale which contained six symptoms commonly thirst; associated with heat stress: irritability; headache; and …

Firefighter thermoregulation: clothingfit, cognition, and menthol
… humidity of the micro-environment may lead to hypohydration without the benefit of cooling. The present study had three purposes: 1) to evaluate firefighter gear fit (loose and regular); 2) to assess cognitive responses to 30-minute exposures in 21 °C and 33 °C and 60% RH; and 3) to assess the …
