Surveys reveal that two out of three of us know we should drink eight 8-ounce servings of water daily, but only one in two of us are following the recommendation. In fact, the average American drinks less than five glasses of water every day.

Insufficient water even can lead to kidney disease and chronic dehydration. Put simply, your body struggles when deprived of water.
