Answer to Question 1
Water keeps the body hydrated, regulates body temperature, transports
nutrients, makes up part of all cells, hydrates the skin, lubricates joints, and
facilitates digestion, absorption, and excretion. It also participates in the body's
chemical reactions.
Dehydration causes a deficiency of water in the body's cells and fluids. Overhydration
causes water intoxication, a condition in which there is too much
water and not enough electrolytes in the body and which causes a shift in the
amount of water in the cells. Both dehydration and water intoxication can be
life threatening.
The AI for water each day is 3.7 liters for men and 2.7 liters for women. These
figures include water from all sources: food, beverages, and drinking water.
Individual fluid needs vary according to physical activity and exposure to high
temperatures.
