    this makes interesting reading, i've always thought that this idea held no water (in a matter of speaking).

    Back in the 40s studies suggested that people drink 8 glasses of fluids a day. Over the decades this information became misinformation, evolving into the 8 glasses of water a day we're so used to. It's like a bad case of the telephone game.

    I found a website some time ago that dispells medical myths. I can't remember what it's called, but I'm sure it wouldn't be too hard to find on google.

    Always thought the 8 glass of water was bogus. Seeing people carrying big bottles of water made me shake my head. Swim alot and often see other swimmers with water bottles ay the end of their lane. Hardly any of them swim a mile!

    Fluids yes, that much water, no.

    Not quite true. The study in the fourties calculated you needed that much liquid, but didn't say you should drink it. They included water from your food as well.

    After, it evolved into "you must drink it." And then, more recently, into "it must be water, nothing else counts, not even tea." I've heard various reports as to the reason behind that, the fear of milk and the bottled water lobby being among them. No idea what's the real reaosn.

    This is one of those myths we've known is a myth for a long time. Every so often someone does yet another study proving it wrong in a different way and a couple years later it's forgotten.

    Shockingly, we, like *every other mammal on the planet* will drink enough liquid if we drink when we're thirsty.

    and let's not forget what kind of damage all those BOTTLES of water are doing to the planet - here's an article from the san francisco chronicle:

    Diver: But don't some fluids actually cause you to lose more than you consume, like those that contain caffeine and alcohol?

    I'm asking. I don't know the answer.

    I think the women at work carry bottles of water more for dieting purposes than hydration. ...occupies their feeding reflex and fills their stomachs or something like that.

    In the Midwest, my people carry giant plastic water bottles with neon-colored plastic straws, strapped to special holders in our fanny packs, which are wrapped around our ample waists, clothed in pastel-colored pajama-like "sportswear", while padding slowly around the mall, talking how important it is to drink 8 glasses a day and exchanging the latest updates on that little girl who fell down the well.

    This is an important part of our mating ritual.

    K

    PS I kid! We never drank water in the Midwest. Only diet pop.

    That is a paraphrased article not backed up by any scientific study just opinion.

    There are plenty of scientific studies not speculative opinion that state otherwise a good one to start with is:

    on that site you will find numeorus related articles regarding hydration that are actually backed by study and not some glossy magazine or cruddy paper trying to fill up a blank page with misinformation

    If you perform excessive excercises during the week, your body DOES need more water as you lose water when excercising. Also if you don't eat foods such as cabbage, lettuce etc, then where are you getting water from?

    I try to drink water regularly but I find myself not thirsty during the course of a day, will realize that I hadn't drank anything in 3 or 4 hours. even though I like water, its hard for me to drink even 4 8oz glasses of water a day. Doesn't your body systems let a person know when they need water, by thirst? I hope my 3 or 4 cups of coffee a day counts for hydration, cause I at least get that down. Just read that coffee helps cut down colesteral build up, and can reduce the likelyhood of alzheimers. Ha !!! there's a study out there for about anything a person wants to have justified isn't there !!!

    Coffee is also a diuretic. It inhibits ADH and makes your kidneys release more water into your urine. This can actually remove water from your system and work against your average water intake. Though I doubt you can calculate if it's putting you in the red, I think you're okay.

    The advice to drink when you're thirsty - because that's the way your body evolved - is very good advice.

    Being able to safely drink water is a pretty new development in human history. But humans have been making alcohol or teas for a very long time to make water safe to drink, and there sure seem to have been a lot of survivors!

    I probably drink close to 8 glasses a day, but that might include juices, soymilk, soups, herbal tea, etc. I don't count caffeinated drinks in that tally because I know they go right through me.

    In winter I tend to drink alot because with the heating drying out the air, i get thirsty. I usually drink about 16oz while i workout, and in the summer, i drink to beat the heat.

    Speaking of how this myth evolved. . . here's one more recent angle: The (absurd) notion that even 8 glasses of water a day STILL wasn't enough. . .

    The most ridiculous example I recall reading (rather recently) was an article in a supposedly reliable national magazine that recommended 12 -- TWELVE -- glasses of water a day. I guess the writer thought that would be a 50 percent improvement.

    Question everything. Don't be cynical -- but it's OK to be a cheerful, open-minded skeptic.

    If I understand the article correctly, drinking a reasonable quantity of water, say 20 oz bottle, the water temperature causes my body/ metabolism to increase to warm the water to body temperature. That in turn I am actually burning more calories than if not drinking water. I assume that this theory applies to most cool liquids and not exclusively to water.

    Based upon your research, how does this theory work with warm liquids like coffee, tea, or soup?
