Water Intake of an individual varries depending on the climate you live in and the type of lifestyle you lead. Some kids/women may need more or less, depending on their overall health, including if they have certain illnesses, take specific medications and more. It also depends on how much they exercise and the level of intensity, and the cimatic conditions. Water comprises from 75% body weight in infants to 55% in elderly and is essential for cellular homeostasis and life.
Some ailments that require more fluid intake, are bladder disorders or kidney stones. Other conditions of the heart, kidney, liver and adrenal system may upset excretion of water and require that you control your fluid consumption. Those who train daily or take part in any strenuous activity, it is necessary to drink more water to replenish for the fluid loss. An added 400 to 600 milliliters (more than 2 glasses) of water should be sufficient for short periods of exercise, but intensive exercise that lasts over an hour requires additional fluid intake.
Women should drink 2.2 liters (about 10 glasses) a day. Pregnant or breastfeeding Women who are pregnant or breast-feeding need more water to stay well hydrated. Large amounts of fluid are required to make breastmilk. The Institute of Medicine suggests that expecting mothers drink 2.5 liters (about 10 cups) of fluids every day and women who breastfeed drink 3.2 liters (about 13 cups) of fluids daily. Babies and infants need 0.7 to 0.8 liters of water daily from breast milk or formula.
Talkings of children or teen, they should drink at least six to eight cups of water a day and eat the recommended number of servings of fruits and vegetables every day.

Effect of Aging on Fluid Intake
The thirst and fluid ingestion responses of older persons to a number of stimuli have been compared to those seen in younger persons. Following water deprivation older persons are less thirsty and drink less fluid compared to younger persons. The decrease in fluid consumption is predominantly due to a decrease in thirst as the relationship between thirst and fluid intake is the same in young and old persons. Older persons drink insufficient water following fluid deprivation to replenish their body water deficit. When dehydrated older persons are offered a highly palatable selection of drinks, this also failed to result in an increased fluid intake.
Studies support small changes in the regulation of thirst and fluid intake with aging. Defects in both osmoreceptors and baroreceptors appear to exist as well as changes in the central regulatory mechanisms mediated by opioid receptors. Because of their low water reserves, it may be prudent for the elderly to learn to drink regularly when not thirsty and to moderately increase their salt intake when they sweat. Better education on these principles may help prevent sudden hypotension and stroke or abnormal fatigue can lead to a vicious circle and eventually hospitalization.
