Editor’s Note:  On a recent visit to the pediatrician  (shout out to Andy Shulstad at Charlotte Peds) my son & I learned that we should be drinking 1/2 to 2/3 oz of water for every pound of weight.  That amount exceeds the “8×8″ rule I’d been going by, and it’s significantly more for him, since he runs several miles in XC every day, is 6’1” and weighs 160 lbs.  In researching online the benefits of proper hydration, I came across the following info to help figure out how much is enough:
Calculating Your Daily Water Needs
Know Your weight: The first step to knowing how much water to drink everyday is to know your weight. Â The amount of water a person should drink varies on their weight = a 200 pound man and 120 pound woman require different amounts of water every day.
Multiply by a minimum of 1/2:Â Â Multiple your weight by 1/2 (or 50%) to determine how much water to drink daily AT MINIMUM. Â This is for sedentary persons. Â For example, at 160 pounds our son multiplies that by 1/2 and learns he should be drinking at least 80Â ounces of water every day. Â And that’s if he only sits on the sofa playing video games all day. Â Which does happen, but not once school is back. Â Many guidelines suggest the minimum is higher, especially if you are trying to LOSE weight. Â In that case, use a factor of 2/3 your weight to determine your daily ounces.
Adjust for activity Level: Finally you will want to adjust that number based on how often you work out, since you are expelling water when you sweat. You should add 12 ounces of water to your daily total for every 30 minutes that you work out. So if you work out for 45 minutes daily, you would add 18 ounces of water to your daily intake.
What are the benefits of being well-hydrated?
There are plenty of studies to support the negative effect of dehydration, which include impairment of mood, concentration, energy levels and endurance. Â Dehydration can also increase the frequency of headaches.
There is evidence to suggest that drinking a big 16 oz  glass of water prior to your meals will help you maintain or lose weight, by reducing the amount of calories you consume. There are even some studies that show that drinking more cold water can speed up your metabolism.  And there is anecdotal evidence that staying well hydrated improves the condition of your skin, reducing acne and dryness, particularly chronically dry lips.
