The standard answer has always been to drink 8, 8-ounce glasses per day, or 64 ounces. Some recommendations say that for the very active that number should be higher, and is determined by dividing your weight in half and drinking that many ounces. (i.e. a 150 pound person would drink 75 ounces of water.) A recent report from the British Medical Journal says that we need less water than originally thought.
