Should We Really Be Drinking Eight Glasses of Water Every Day?

Water is crucial for the human body. It helps regulate temperature, transports nutrients, flushes waste, and lubricates joints. In fact, up to 60 percent of the human body is made of water. But while humans certainly need to stay hydrated, the idea that everyone should drink eight 8-ounce glasses of water each day is not necessarily true, nor is there concrete scientific evidence to support this guidance. Besides, everything that you eat contains some water. According to a 2004 report from the National Academy of Sciences, the average North American gets about 20 percent of his or her daily water intake through food sources.

Thirsty? It's simple -- drink some water:

  • The National Academy of Sciences suggests that women should consume 91 fluid ounces (2.7 liters) of water from food and beverages daily, while men should intake approximately 125 ounces (3.7 liters).

  • But these are just guidelines. Your needs depend on age, weight, level of physical activity, general health, and the climate in which you live. Ultimately, let thirst be your guide.

  • You can also get a clue from the color of your urine. Dark yellow or orange urine usually indicates dehydration. Well-hydrated urine should look pale yellow or colorless.

Thirst is the worst guide. Most people don't drink water because they are not thirsty. Yet they are dehydrated. The volume and color of urine are better indicators. But the gold standard is to periodically check your blood urea/nitrogen (serum urea and creatinine).
