Eighty-six children in Florida died of complications associated with diarrhea between 1985 and 1990, deaths which constituted an important preventable fraction of infant mortality. The state will support health professionals in reducing the number of hospitalizations and deaths due to diarrheal complications, Governor Lawton Chiles announced in September 1991, and the Florida Department of Health [...]
This paper compares the hydration ability of three commercially-available sports drinks with water under conditions of rest and exercise, using a deuterium dilution technique. For the rest group, 0.05g/kg of body weight of deuterium, contained in gelatine capsules, was ingested with one of the test solutions and saliva samples were collected every five minutes for [...]

Caffeine is regarded as a diuretic despite evidence that hydration is not impaired with habitual ingestion. The purpose of this study was to determine whether a caffeinated sports drink impairs fluid delivery and hydration during exercise in warm, humid conditions (28.5 degrees C, 60% relative humidity). Sixteen cyclists completed 3 trials: placebo (P), carbohydrate-electrolyte (CE), [...]
Healthy humans regulate daily water balance remarkably well across their lifespan despite changes in biological development and exposure to stressors on hydration status. Acute or chronic body water deficits result when intakes are reduced or losses increase, but day-to-day hydration is generally well maintained so long as food and fluid are readily available. Total water [...]
BACKGROUND: It has been reported that the oropharyngeal afferent pathway behaves as a first-order factor regulating body fluid. However, the neural mechanism has not yet been clear. This study was designed to elucidate the characteristics of the neural mechanism in man. METHODS: Healthy human subjects kept either an isotonic or hypertonic solution in the oral [...]

It is understood that water is the most essential nutrient for life, yet research elucidating the fine points of hydration and fluid needs is still in its youth. Public recommendations based on scientific evidence are not always translated by the media into useful and practical guidelines. CONCLUSION: Further research investigating the benefits of all fluids, [...]
Thirst and drinking function to maintain body water balance and are basic to survival. Thirst is often associated with a dry unpleasant-tasting mouth and the feeling of a need to obtain water; it can result from dehydration, decreased vascular volume, dry mouth, pharmacologic agents, or inappropriate activation of the thirst mechanism. Drinking involves the motor [...]
