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 [...]

The effect of prescribed fluid consumption on physiology and work behavior of wildfire fighters.

The purpose of this study was to examine 1) wildfire fighters' ability to consume the prescribed fluid volume (1200 mL h(-1)), 2) the effect of fluid intake on plasma sodium and hydration, and 3) the effect of fluid intake on firefighters' heart rate, core temperature and activity during emergency suppression shifts. METHODS: Thirty-four firefighters were [...]

The effects of dehydration, moderate alcohol consumption, and rehydration on cognitive functions.

This study investigated the impact of mild-moderate dehydration on alcohol-induced deteriorations in cognitive functions. Sixteen healthy males participated in a single-blind, placebo-controlled cross-over design study involving 4 experimental trials (separated by ≥7 d). In each trial, participants were dehydrated by 2.5% body mass through exercise. After 1 h recovery in a thermo-neutral environment (22 ± 2 °C, 60-70% relative humidity) [...]

Methods for assessing the effects of dehydration on cognitive function.

Studying the effects of dehydration on cognitive function presents a variety of unique and difficult challenges to investigators. These challenges, which are addressed in this article, can be divided into three general categories: 1) choosing an appropriate method of generating a consistent level of dehydration; 2) determining and effectively employing appropriate and sensitive measures of [...]

Hydration for recreational sport and physical activity.

This review presents recommendations for fluid needs and hydration assessment for recreational activity. Fluid needs are based on sweat losses, dependent on intensity and duration of the activity, and will vary among individuals. Prolonged aerobic activity is adversely influenced by dehydration, and heat exposure will magnify this effect. Fluid needs predicted for running 5-42 km at [...]

Thirst and hydration status in everyday life.

Water is an essential nutrient for all persons; thus, maintaining a chronic state of optimal hydration is recognized to provide health benefits. Fluid balance is maintained via thirst, a feedback-controlled variable, regulated acutely by central and peripheral mechanisms. However, voluntary drinking is also a behavior influenced by numerous social and psychological cues. Therefore, whether "thirst-guided" [...]

Nutrition and Fluid Optimization for Patients With Short Bowel Syndrome.

  Short bowel syndrome (SBS) is characterized by nutrient malabsorption and occurs following surgical resection, congenital defect, or disease of the bowel. The severity of SBS depends on the length and anatomy of the bowel resected and the health of the remaining tissue. During the 2 years following resection, the remnant bowel undergoes an adaptation [...]

A rapid beverage intake questionnaire can detect changes in beverage intake.

Attention on beverage intake, specifically sugar-sweetened beverages (SSB), has increased in recent years. A brief valid, reliable and sensitive assessment tool for quantifying beverage consumption and determining its influence on weight status could help to advance research on this topic. The valid and reliable 15-item beverage questionnaire (BEVQ-15) estimates mean daily intake of water, SSB [...]

Promoting healthy drinking habits in children.

Good fluid intake in children is vitally important as they have immature thirst mechanisms, relatively high rates of fluid loss and are physically active. Poor fluid intake may affect children's cognitive functioning as well as bladder control. Research shows that children drink seven times as much soft drink as water. Schools have a vital role [...]
