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 [...]

The purpose of this study was to assess the influence of rehydration with a caffeinated beverage during nonexercise periods on hydration status throughout consecutive practices in the heat. Ten (7 women, 3 men) partially heat- acclimated athletes (age 24 +/-1y, body fat 19.2 +/- 2 %, weight 68.4 +/- 4.0 kg, height 170 +/- 3 [...]
The purpose of this experiment was to explore the complex relationship between fluid consumption and consumption factors (thirst, voluntary dehydration, water alliesthesia, palatability, work-rest cycle) during a simulated 14.5-km desert walk (treadmill, 1.34 m X s-1, 5% grade, 40 degrees C dry bulb/26 degrees C wet bulb, and wind speed of approximately 1.2 m X [...]
OBJECTIVE: To compare early oral hydration versus the conventional intravenous fluid replacement after elective cesarean section. METHODS: Two hundred women performed elective cesarean section were selected and randomized to: Regimen I (n = 100): early oral hydration (sips of fruit juices sweetened with honey once the women felt thirst immediately after the operation, then solid [...]
OBJECTIVE: To measure the effect on hydration of two regimens, one that included drinking water as part of the dietary beverages and one that did not. METHODS: In healthy, sedentary subjects, two different diets were evaluated for their effect on hydration. Trial A provided plain water to drink as part of the beverages served. Trial [...]

OBJECTIVE: Our purpose was to determine whether acute maternal hydration in pregnancies with third-trimester oligohydramnios (1) increases amniotic fluid index and hourly fetal urine production rate and (2) alters uteroplacental perfusion and fetal blood flow. STUDY DESIGN: Ten women with third-trimester oligohydramnios (amniotic fluid index < or = 5 cm) and 10 controls with normal [...]
