HYDRATION, HYDRATION, HYDRATION
Throughout the world, large numbers of manual workers perform physically demanding labour in conditions of high environmental heat stress. Although the importance of adequate hydration in combating heat stress is universally recognized, studies in a range of worker groups have demonstrated a disturbingly poor hydration level in a high proportion of at-risk workers. Management of [...]
Fluid replacement and glucose infusion during exercise prevent cardiovascular drift.
This study examined the influence of both hydration and blood glucose concentration on cardiovascular drift during exercise. We first determined if the prevention of dehydration during exercise by full fluid replacement prevents the decline in stroke volume (SV) and cardiac output (CO) during prolonged exercise. On two occasions, 10 endurance-trained subjects cycled an ergometer in [...]
EFFECTS OF ROOIBOS TEA, BOTTLED WATER, AND A CARBOHYDRATE BEVERAGE ON BLOOD AND URINARY MEASURES OF HYDRATION AFTER ACUTE DEHYDRATION
Rooibos tea contains polyphenol antioxidants, including flavonoids and phenolic acids that are potent free radical scavengers and has purported benefits for accelerated rehydration. The objective was to evaluate the effects of three different drinks (rooibos tea, bottled water, and a carbohydrate beverage) on blood and urinary markers of hydration after acute dehydration in collegiate wrestlers. [...]

HYDRATION STATUS AND THE DIURETIC ACTION OF A SMALL DOSE OF ALCOHOL
Aim: This study was conducted to examine the effect of consuming a dilute alcohol solution (weak beer) on urine production in euhydrated and hypohydrated individuals. Methods: Twelve males completed an intermittent cycle protocol in hot (35.1 +/- 0.3 degrees C), humid (68 +/- 2%) conditions to dehydrate by 1.9 +/- 0.3% body mass in the [...]
Dietary reference intakes for water, sodium, potassium, chloride and sulphate.
This report is one in a series that presents a comprehensive set of reference values for nutrient intakes for healthy U.S. and Canadian individuals and populations. It is a product of the Food and Nutrition Board (FNB) of the Institute of Medicine, working in cooperation with Canadian scientists. The report establishes a set of reference [...]
PERCEPTUAL RESPONSES WHILE WEARING AN AMERICAN FOOTBALL UNIFORM IN THE HEAT
CONTEXT: The protective equipment worn during American football has been shown to increase thermal strain; however, the perception of this increased heat has not been examined. OBJECTIVE: To evaluate perceptual responses of American football players while wearing different uniforms during exercise in the heat and to evaluate how these responses may be used to monitor [...]
WATER AS AN ESSENTIAL NUTRIENT: THE PHYSIOLOGICAL BASIS OF HYDRATION
Water intake was described and quantified in samples of urban Guatemalan schoolchildren stratified by gender and socio-economic status. The frequency of consumption and quantity of plain water drinking was estimated from oneday pictorial registries of all beverages, foods and snacks consumed over a 24-h period collected from 449 3rd and 4th graders from two social [...]
THE EFFECT OF ORAL REHYDRATION SOLUTION AND RECOMMENDED HOME FLUIDS ON DIARRHOEA MORTALITY
BACKGROUND: Most diarrhoeal deaths can be prevented through the prevention and treatment of dehydration. Oral rehydration solution (ORS) and recommended home fluids (RHFs) have been recommended since 1970s and 1980s to prevent and treat diarrhoeal dehydration. We sought to estimate the effects of these interventions on diarrhoea mortality in children aged <5 years. METHODS: We [...]
