The Nutrition Information Center at The New York Hospital - Cornell Medical Center offers the following tips for maintaining proper hydration:
(NEW YORK, May 11, 1998) A significant number of Americans may be drinking themselves to dehydration by consuming too little water and too may beverages that rob the body of water, according to the results of a national consumer survey released today. The survey of 3,003 Americans, conducted by Yankelovich Partners for the Nutrition Information Center at The New York Hospital - Cornell Medical Center and the International Bottled Water Association, reveals that Americas glass is half empty. The good news is that the average American drinks nearly eight daily servings of hydrating beverages, such as water, milk, juice and decaffeinated soft drinks. But that is undermined by the nearly five servings of caffeine- or alcohol-containing beverages that respondents report drinking each day. Scientific research shows that caffeine and alcohol act as diuretics, causing the body to lose water through increased urination. "The net result is that most Americans are probably only getting about a third of the valuable hydration benefits they need," says Barbara Levine, R.D.,Ph.D., Director of the Nutrition Information Center. "The vast majority arent drinking enough water to begin with, and, to make matters worse, many don't realize that beverages containing alcohol an caffeine actually rob the body of water." Awareness of Water Needs is High, but Compliance is Low While two out of three survey respondents say they know that health and nutrition experts recommend drinking eight, eight-ounce servings of water a day, one in two admits do not getting enough. In fact, the survey shows that the average American only consumes 4.6 servings of water a day. Indeed, only one in five meets the "eight a day" recommendation. More than double that amount (44 percent) drink three or fewer servings of water daily. And nearly one in 10 (9 percent) report drinking no water at all. "Its troubling that so few Americans drink the recommended amount of water daily," notes Levine. "The consumption of water and other hydrating beverages is crucial for proper retention and use of the bodys water in complex and intricate biochemical processes." Water comprises more than 70 percent of solid tissue such as muscle in the human body. Besides oxygen, it is the most important nutrient in the body, functioning as a physiological "jack of all trades." It has an important role in nearly every major function in the body, regulating body temperature, carrying nutrients and oxygen to cells, removing waste, cushioning joints, and protecting organs and tissues. It is not surprising, then, that those survey respondents who say they drink eight or more servings of water a day are less likely to report experiencing the symptoms of dehydration than those who drink three or fewer glasses of water daily. Low-volume water drinkers, for example, are more likely to report having dry, itchy skin or feeling tired and groggy when they wake up or at mid-day, two classic signs of dehydration. Levine notes that longer-term, more severe dehydration presents more serious problems, dangerously affecting blood pressure, circulation, digestion, kidney function and nearly all body processes. Survey Reveals Hydration "Knowledge Gaps" While survey respondents are widely aware of minor dehydration symptoms such as dry skin and headaches, they are less knowledgeable about the causes of dehydration. For example, one in five does not know that caffein dehydrates -- a key finding, considering that Americans down 4.1 daily servings of coffee, caffeinated sodas and tea. Additionally, nearly half (47 percent) are unaware that the human body loses as much water when asleep as when awake, while more than a third (37 percent) do not know that the body needs as much water in cold weather as it does in warm weather. One in 10 respondents say they wait until they are thirsty before drinking a beverage. They do not realize that thirst lags far behind the bodys need for water and does not adequately signal the bodys hydration needs. "This look at Americas hydration habits suggests what could be a significant and widespread health concern," say Levine. "The survey clearly demonstrates the need for much more public education about the benefits of proper hydration and the problems even minor dehydration can cause." The Nutrition Information Center is a component of the Clinical Nutrition Research Unit, The New York Hospital - Cornell Medical Center, Memorial Sloan-Kettering Cancer Center. The International Bottled Water Association (IBWA) is the trade association
representing 85 percent of the bottled water sold in the U.S. today. Founded
in 1958, IBWAs membership includes U.S. and International bottlers and
distributors. Additional members include manufacturers of bottled water
equipment and supplies. Consumers can contact IBWA at 1-800-WATER-11 or
log onto IBWAs web site - www.bottledwater.org for more information concerning
bottled water and a list of members brands.
With heat wave conditions predicted for an extended period, its important
to drink plenty of water. Proper hydration is critical during heat waves,
when loss of water due to extreme heat and humidity can be potentially
life-threatening. Following are the facts about how the heat affects the
body and water essential role in maintaining health.
Keeping Properly Hydrated Is Extremely Important In Above-Normal Temperatures The National Weather Service predicts above-normal temperatures across much of the United States this summer. As the nation prepares for a hot summer, Felicia Busch, R.D.,M.P.H. and ambassador to the American Dietetic Association, offers the following "Dos and Donts" for summer hydration. Dos
