I’m sure you’ve all heard the saying drink eight eight-ounce glasses of water a day to maintain hydration. That’s about two liters or half a gallon of water. For some people, fewer glasses a day might be enough. Therefore, you need to modify your water based on your personal needs. A recent medical literature review showed that there is no benefit to drinking 8 glasses of water a day for people without a history of kidney stones. As a matter of fact, drinking too much water can be detrimental to some people who have certain health conditions. Nutritionist Frederick J Stare lowered the targeted number of glasses to six from eight and included other beverages such as coffee, tea, milk, soft drinks, and water rich fruits and vegetables as a source of water consumption. He believes you don’t need to rely only on water to meet your fluid needs. Other sources can also contribute to your daily water intake.
