Many fruits, vegetables and soups are at least 80 percent water, so they can count toward your daily intake. Milk, diet sodas, unsweetened carbonated waters, most herbal teas, decaffeinated teas and decaf coffee can substitute, cup-for-cup, for pure water. The same is not true of fruit juices and sugar-sweetened drinks. Although theses other beverages still count as fluid sources, there sugar content can slow down your body's water absorption. Finally, don't count coffee or alcohol as a water substitute: Caffeine is a mild diuretic (a substance that helps remove water from the body via urine). This makes coffee and other caffeinated beverages poor sources of water.” Clinical GuidelinesInternet SitesFeatured SitesNIH - Fluid and Electrolyte Balance NIH - Medical Encyclopedia Dehydration NHS - Heat exhaustion and heatstroke NIH - Medical Encyclopedia Dehydration NIH - Medical Encyclopedia Dehydration Heat emergencies NIH - Medical Encyclopedia Skin turgor NIH - Medical Encyclopedia Traveler’s diarrhea diet NIH - Medical Encyclopedia Water in diet NIH - Medical Encyclopedia Nutrition and athletic performance US EPA - Local Drinking Water Information Organizations - Private: Related InfoMedSearch TopicsRelated Topics - Highlighted Articles
Sports and Injury PreventionResearchers Examine Water During Workouts "Three decades ago, the top warning sounded by race officials was dehydration. Athletes were told to constantly hydrate after several studies found a link between dehydration and a rise in body temperature, which can lead to heat stroke. But now researchers are taking a second look at the risks of drinking too much fluid during exercise. Hyponatremia, or water intoxication, was thrust into the spotlight after the back-to-back deaths of two female runners in 2002, including one who ran in the Boston Marathon. In both cases, the women drank excessive amounts of fluids." Aging - Anti-AgingStrategies for ensuring good hydration in the elderly. (Nutr Rev. 2005) "Dehydration is a frequent etiology of morbidity and mortality in elderly people. It causes the hospitalization of many patients and its outcome may be fatal. Indeed, dehydration is often linked to infection, and if it is overlooked, mortality may be over 50%. Older individuals have been shown to have a higher risk of developing dehydration than younger adults. Modifications in water metabolism with aging and fluid imbalance in the frail elderly are the main factors to consider in the prevention of dehydration. Particularly, a decrease in the fat free mass, which is hydrated and contains 73% water, is observed in the elderly due to losses in muscular mass, total body water, and bone mass. Since water intake is mainly stimulated by thirst, and since the thirst sensation decreases with aging, risk factors for dehydration are those that lead to a loss of autonomy or a loss of cognitive function that limit the access to beverages." A typology of oral hydration problems exhibited by frail nursing home residents. (J Gerontol Nurs. 2006) "Dehydration remains a substantial problem for nursing home residents, often with poor health outcomes. … Dehydration events occurred in 31% (11 of 35) of residents during the 6-month period."
