A PERSON WHO IS VERY THIRSTY NEED TO DRING SOMETHING TO FULLFIL HIS/HER THIRSTY, BUT AMONG ALL THE DRINGS WATER IS THE ONLY LIQUID THAT CAN REALLY QUENCH YOUR THIRST;NOTHING CAN BEAT IT

About 70% of the non-fat mass of the human body is made of water. To function properly, the body requires between one and seven liters of water per day to avoid dehydration; the precise amount depends on the level of activity, temperature, humidity, and other factors.

With physical exertion and heat exposure, water loss will increase and daily fluid needs may increase as well.It is not clear how much water intake is needed by healthy people, although some experts assert that 8–10 glasses of water (approximately 2 liters) daily is the minimum to maintain proper hydration.

The notion that a person should consume eight glasses of water per day cannot be traced back to a scientific source. The effect of water intake on weight loss and on constipation is also still unclear. Original recommendation for water intake in 1945 by the Food and Nutrition Board of the National Research Council read: -

"An ordinary standard for diverse persons is 1 milliliter for each calorie of food. Most of this quantity is contained in prepared foods."

The latest dietary reference intake report by the United States National Research Council in general recommended (including food sources): 2.7 liters of water total for women and 3.7 liters for men. Specifically, pregnant and breastfeeding women need additional fluids to stay hydrated. According to the Institute of Medicine—who recommend that, on average, women consume 2.2 litres and men 3.0 litres—this is recommended to be 2.4 litres (approx. 9 cups) for pregnant women and 3 litres (approx. 12.5 cups) for breastfeeding women since an especially large amount of fluid is lost during nursing.

For those who have healthy kidneys, it is rather difficult to drink too much water, but (especially in warm humid weather and while exercising) it is dangerous to drink too little. People can drink far more water than necessary while exercising, however, putting them at risk of water intoxication, which can be fatal. In particular large amounts of de-ionized water are dangerous.Normally, about 20 percent of water intake comes in food, while the rest comes from drinking water and assorted beverages (caffeinated included). Water is excreted from the body in multiple forms; including urine and feces, sweating, and by water vapor in the exhaled breath.
