Thermal stress in north Western Australian iron ore mining staff.

INTRODUCTION: Demand for Australian mined iron ore has increased employment within this sector, thus exposing increased numbers of workers to the harsh Australian climate. This study examined the influence of hot (>30°C wet bulb globe temperature) environmental temperatures, consistent with working in North Western Australia, on iron ore mining staff. METHODS: Core temperature, hydration status, [...]

Whole-Body Heat Loss during Exercise in the Heat Is Not Impaired in Type 1 Diabetes.

Purpose: To determine if individuals with type 1 diabetes exhibit impairments in local and whole-body heat loss responses that could impact core temperature regulation during exercise in the heat compared to matched, non-diabetic individuals. Methods: Twelve otherwise healthy individuals with type 1 diabetes (HbA1c = 7.7±0.3%) and 12 controls matched for age, sex, body surface [...]

Is whole-body thermoregulatory function impaired in type 1 diabetes mellitus?

During periods of extreme heat individuals with diabetes have greater rates of heat-related morbidity and mortality compared to their non-diabetic counterparts. The reason for this discrepancy is currently unknown. Furthermore, there is a lack of information about whether or not individuals with type 1 diabetes are at a thermoregulatory disadvantage during strenuous physical activity especially [...]

Do Heat Events Pose a Greater Health Risk for Individuals with Type 2 Diabetes?

Abstract Chronic medical conditions such as type 2 diabetes may alter the body's normal response to heat. Evidence suggests that the local heat loss response of skin blood flow (SkBF) is affected by diabetes-related impairments in both endothelium-dependent and non-endothelium-dependent mechanisms, resulting in lower elevations in SkBF in response to a heat or pharmacological stimulus. [...]

Hypohydration and acute thermal stress affect mood state but not cognition or dynamic postural balance.

Equivocal findings have been reported in the few studies that examined the impact of ambient temperature (T a) and hypohydration on cognition and dynamic balance. The purpose of this study was to determine the impact of acute exposure to a range of ambient temperatures (T a 10-40 °C) in euhydration (EUH) and hypohydration (HYP) states on [...]

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 [...]

Hydration effects on temperature regulation

During exercise in the heat, sweat output often exceeds water intake which results in a body water deficit (hypohydration) and electrolyte losses. Daily water losses can be substantial and persons need to emphasize drinking during exercise as well as at mealtime. Aerobic exercise tasks are likely to be adversely affected by heat stress and hypohydration; [...]
