Water is the largest single constituent of the human body and is essential for cellular homeostasis and life. Total water intake includes drinking water, water in beverages, and water that is part of food. Although a low intake of total water has been associated with some chronic diseases, this evidence is insufficient to establish water intake recommendations as a means to reduce the risk of chronic diseases.

Instead, an Adequate Intake AI for total water is set to prevent deleterious, primarily acute, effects of dehydration, which include metabolic and functional abnormalities. The primary indicator of hydration status is plasma or serum osmolality. Because normal hydration can be maintained over a wide range of water intakes, the AI for total water from a combination of drinking water, beverages, and food is set based on the median total water intake from U.

The AI for total water intake for young men and women ages 19 to 30 years is 3. Water contained in food provided ap-. Canadian survey data indicated somewhat lower levels of total water intake.

As with AIs for other nutrients, for a healthy person, daily consumption below the AI may not confer additional risk because a wide range of intakes is compatible with normal hydration.

In this setting, the AI should not be interpreted as a specific requirement. Higher intakes of total water will be required for those who are physically active or who are exposed to hot environments.

Over the course of a few hours, body water deficits can occur due to reduced intake or increased water losses from physical activity and environmental e. However, on a day-to-day basis, fluid intake, driven by the combination of thirst and the consumption of beverages at meals, allows maintenance of hydration status and total body water at normal levels. Because healthy individuals have considerable ability to excrete excess water and thereby maintain water balance, a Tolerable Upper Intake Level UL was not set for water.

Water, which is the solvent for biochemical reactions, has unique physical properties e. Water is also essential for maintaining vascular volume and serves as the medium for transport within the body by supplying nutrients and removing waste. In addition, cell hydration has been has been suggested to be an important signal to regulate cell metabolism and gene expression Haussinger et al. Daily water intake must be balanced with losses in order to maintain total body water.

Body water deficits challenge the ability to maintain homeostasis during perturbations e. In very unusual circumstances, excess consumption of hypotonic fluids and low sodium intake may lead to excess body water, resulting in hyponatremia and cellular edema. Despite the importance of adequate water intake, there is confusion among the general public and health care providers on the amount of water that should be consumed Valtin, , in part because of misinterpretation of previous recommendations NRC, High body water volume is particularly evident in newborns, whose body water content of fat-free mass may exceed 75 percent Fomon, Infants also have a relatively higher water content in the extracellular compartment and a lower water content in the intracellular compartment compared with older children Van Loan and Boileau, For adults, fat-free mass is approximately 70 to 75 percent water, and adipose tissue is approximately 10 to 40 percent water.

With increasing fatness, the water fraction of adipose tissue decreases Martin et al. Reprinted with permission, from Van Loan and Boileau Copyright by CRC Press. Reprinted with permission, from Visser and Gallagher Copyright by John Libbey Eurotext. Note that individual variation exists for the hydration of fat-free tissue and values remain relatively stable with increasing age.

Neither ethnicity nor gender altered the hydration of fat-free mass. Other investigators have supported the observation that age and gender do not markedly alter the hydration of fat-free mass in adults Baumgartner et al.

Total body water TBW , comprising extracellular fluid ECF and intracellular fluid ICF , averages approximately 60 percent of body weight, with a range from approximately 45 to 75 percent Altman, Variability in TBW is primarily due to differences in body composition. TBW is usually measured by volume distribution of an appropriate indicator e.

Table provides TBW values for different age and gender groups based upon indicator dilution methods Altman, Women and older persons have reduced TBW primarily because of having lower fat-free mass and increased body fat. Athletes have relatively high TBW values by virtue of having a high fat-free mass, low body fat, and high skeletal muscle glycogen levels. High skeletal muscle glycogen levels increase the water content of fat-free tissue due to osmotic pressure exerted by glycogen granules within the muscle sarcoplasm Neufer et al.

The ECF is further divided into the interstitial and plasma spaces. These are not static volumes, but represent the net effects of dynamic fluid exchange with varying turnover rates between compartments Guyton and Hall, Perturbations such as exercise, heat exposure, fever, diarrhea, trauma, and skin burns will greatly modify the net volumes and water turnover rates between these fluid compartments.

Water passes through membranes from regions of lower to higher solute concentration by osmosis, which attempts to equalize the concentration differences across the membrane. Cell membranes are freely permeable to water, but they are only selectively permeable to solutes. Water thus distributes across cell membranes to equalize the osmotic concentrations of extracellular and intracellular fluids. Although the two compartments contain different individual solute concentrations, the total equilibrium concentration of cations and anions is the same in each compartment as described by the Gibbs-Donnan equilibrium.

These ions represent 90 to 95 percent of the osmotically active components of the ECF, and changes in their content alter the ECF volume. The marked differences in sodium and potassium concentrations be-. Water exchange between the intravascular and interstitial spaces occurs in the capillaries.

Capillaries of different tissues have varied anatomic structures and therefore different permeability to water and solutes. The transcapillary forces that determine if net filtration i. Oncotic pressure is the osmotic pressure attributed to serum protein concentration e.

Generally, filtration occurs at the arterial end of the capillary, while absorption occurs at the venous end. Incomplete fluid replacement resulting in decreased total body water affects each fluid space as a consequence of free fluid exchange Costill and Fink, ; Durkot et al. The distribution of body water loss among the fluid spaces, as well as among different body organs during water deficit dehydration or hypohydration , was determined in an animal model Nose et al.

The fluid deficit in rats thermally dehydrated by 10 percent of body weight was apportioned between the intracellular 41 percent and extracellular 59 percent spaces. Organ fluid loss was 40 percent coming from muscle, 30 percent from skin, 14 percent from viscera, and 14 percent from bone. Neither the brain nor liver lost significant water content. Various dehydration methods influence the partitioning of water loss from the fluid spaces Mack and Nadel, Body water balance depends on the net difference between water gain and water loss.

Water gain occurs from consumption liquids and food and production metabolic water , while water losses occur from respiratory, skin, renal, and gastrointestinal tract losses. Water is normally consumed by mouth via liquid and food, and this mixture is digested and absorbed within the gastrointestinal tract.

Therefore, water intake can be estimated from measured liquid volumes and tables of food composition. Water losses can be estimated from a variety of physiological and biophysical measurements and calculations Adolph, ; Consolazio et al. The following sections describe each source of water loss or production listed in this table.

The amount of respiratory water loss, via evaporation within the lungs, is dependent on both the ventilatory volume and water vapor pressure gradient Mitchell et al. Ventilatory volume is increased by physical activity, hypoxia, and hypercapnia, whereas the water vapor pressure is modified by the ambient temperature, humidity, and barometric pressure.

Physical activity generally has a greater effect on respiratory water loss than do environmental factors. Ambient air temperature and humidity modify respiratory water losses. The kidneys are responsible for regulating the volume and composition of the ECF via a series of intricate neuroendocrine pathways Andreoli et al.

Renal fluid output can vary depending upon the specific macronutrient, salt, and water load. However, for persons consuming an average North American diet, some of these effects may not be discernable Luft et al. Since there is a limit to how much the kidneys can concentrate urine, the minimal amount of water needed is determined by the quantity of end products that need to be excreted e.

On typical Western diets, an average of mOsmol of electrolytes and other. Healthy older individuals, however, cannot concentrate urine as well as young individuals and thus have a higher minimum urine output. Urine output varies inversely with body hydration status.

Figure depicts the hyperbolic relationship between urine output and. Reprinted with permission, from Lee The extremes depicted in Figure can be exceeded. Urine output can vary widely to maintain total body water; however, there are clearly limits to the amount of conservation and excretion. Physical activity and climate also affect urine output. Exercise and heat strain will reduce urine output by 20 to 60 percent Convertino, ; Mittleman, ; Zambraski, , while cold and hypoxia will increase urine output Freund and Young, ; Hoyt and Honig, Water loss through the skin occurs via insensible diffusion and secreted sweat.

During heat stress, eccrine sweat glands secrete sweat onto the skin surface, which cools the body when water evaporates from the sweat. For a given hot weather condition, the required sweating rate for evaporative cooling is dependent upon the physical activity level metabolic rate.

If the activity is 20 percent efficient, the remaining 80 percent of metabolic energy produced is converted to heat in the body so that W 0. If these persons performed exercise in a hot environment that enabled only evaporative heat loss and they did not sweat, their body temperatures would increase by approximately 1. Since the latent heat of evaporation is 2. Because secreted sweat drips from the body and is not evaporated, higher sweat secretions are often needed to achieve these cooling demands.

If a person is physically active and exposed to environmental heat stress, sweat losses to avoid heat storage can be substantial over a hour period. For persons living in hot climates, daily sweat losses often exceed several liters. As described above, daily sweat losses are determined by the evaporative heat loss requirements, which are influenced by the metabolic rate above example and environment. The environmental factors that modify sweat losses include clothing worn, ambient temperature, humidity, air motion, and solar load.

Therefore, considerable variability will exist for daily sweat losses among different people. Figure provides the distribution of daily sweat-. The average daily sweat loss for 97 men in the desert was 4.
