Are we drinking too much water a day?

are you drinking too much water? how much do you drink each day? i don't drink water as often as i should (according to the article that follows, it may be a good thing), however, i do eat cruched ice and consume my water this way and i drink tea sometimes too.

here is an article from the birmingham news "drinking 8 glasses of water daily seen as dubious advice" ("study finds myths on daily fluid levels")

by lauran neergaard (the associated press) washington (aug. 19) - ``drink at least eight glasses of water a day'' is an adage some obsessively follow, judging by the people sucking on water bottles at every street corner - but the need for so much water may be a myth.

fear that once you're thirsty you're already dehydrated? for many of us, another myth. caffeinated drinks don't count because they dehydrate? probably wrong, too.

so says a scientist who under-took an exhaustive hunt for evidence backing all this water advice and came up mostly, well, dry.

now the group that sets the nation's nutrition standards is studying the issue, too, to see if it's time to declare a daily fluid level needed for good health-and how much leaves you waterlogged.

until then, "obey your thirst" is good advice, says dr. heinz valtin, professor emeritus at dartmouth medical school, whose review of the eight-glass theory appears in this month's american journal of physiology.

it's about time for all the attention, says pennsylvania state university nutritionist barbara rolls, a well-known expert on thirst. "there's so much confusion out there." much of it centers on where you should get your daily water.

"there's this conception it can only come out of a bottle," and that's wrong, notes paula trumbo of the institute of medicine's food and nurtition board, which hopes to decide by march whether to issue the first official water -intake recommendation.

in fact, people absorb much water from the food they eat. fruits and vegetables are 80 to 95 percent water; meats contain a fair amount; even dry bread and cheese are about 35 percent water, says rolls.

that's in addition to juices, milk and other beverages. and many of us drink when we don't really need to, spurred by marketing, salty food and dry environments, rolls says. but the question remains: how much water does the typical, mostly sedentary american truly need? and what's the origin of the theory, heavily promoted by water sellers and various nutrition groups, that the magic number is at least 64 ounces?

valtin, who has spent 40 years researching how the body maintains a healthy fluid balance, determined the advice probably stems from muddled interpretation of a 1945 food and nutrition board report.

that report said the body need about 1 milliliter of water for each calorie consumed-almost 8 cups for a typical 2,000-calorie diet-but that "most of this quantity is contained in prepared foods."

that language somehow has morphed into "at least" 64 oounces daily, baltin says.

this is a nursing board. in a stereotypical manner i will state that nurses inflict the worst nutritional travesties on their own bodies as much as any other evil-doer does to his body. nothing has impressed me about how nurses nourish their own bodies when no one else should know better. unlike doctors, nurses get education on nutrition that should alert them to the do's of good nutrition and the don'ts of bad nutrition. doesn't seem to make an impact. nutrition, water......whatever.......it all falls on deaf ears of the health care provider. i could never figure out why anyone who goes through the rigors to become a nurse doesn't have the will power to control what they eat and consumes the junk that nurses do, and once over 30 becomes more fat than any other profession (not to mention the stress).

i read the same article this morning about water. it is interesting how these health care gurus avoid a single word about physiology when addressing the subject. i thought that was what the entire issue of water consumption is all about....phsiology! not a single mention about the need to flush the body of impurities......nothing about making the kidney's job easier with oral water intake nor the bowel's job easier to absorb water and the advantages therein. yes, the body needs water, and the less you have to make it work to get that water the better it is for the body. in the same manner, proponents of juicing correctly state it is better for the body to benefit from the mecanically fresh juiced product than to consume 8 times that amount in volume of raw product to get the equivalent amount. it is all a matter of efficiency to allow the body to not have to work as hard. i will continue to suck water, thank you. long live clear urine. down with amber.

deucy, welcome to the board!

Well, no, I personally don't drink too much water. I don't drink ENOUGH water. If I drink a single glass of water in the day, I'm impressed with myself. I don't drink much of anything, really. What's up with that? I have 2 cups of coffee in the morning, maybe a diet soda at lunch and milk with dinner. That's about it. If I remember to take a vitamin, I'll have a glass of water with it. But to actually just drink a glass of water....I need to be feeling quite dehydrated. I don't know why this is so; it just is. Water for the sake of water makes me gag. I don't wish it to be so, it just is. :confused:

Zee_RN, I'm just like you. If I drink a glass of water a day, I go WOW, not bad. I really hate water. The only way I can drink it a little better is if I add lemon, and a pack of splenda, and then again that's called LEMONADE, Oh well, I think that by making a goal of drinking at least 8 oz a day that is a good start for me.

I once saw a segment on "The Today Show" about health tips for women and I surprised to learn that the #1 cause of fatigue in American Women is dehydration.

From that day on I decided that I would make an effort to drink more water. It was hard the first couple of days because plain water, ech!! And I was going to the bathroom constantly and found it irritating to my hootie hoo, but my body very quickly became accustomed to having all this water and now I can't go without it. I feel as though I should always have a water bottle in hand. If I don't have an opportunity to drink water through out the day I really feel the need for it when I get home at night and I can guzzle down two full glasses one right after the other.

I feel better when I drink a lot of water and now if I don't get enough I will wake up the next morning nauseated or with a mild headache and crave the water.

The article I read and actually printed out on 8/14 has a bit more information.

Dr. Heinz Valtin of Darmouth Medical School in New Hampshire was the Dr. who did the 10 month study which "found no scientific evidence that supports the 8 glasses of water a day". He has written textbooks on the subject of human water balance and this particular study was published in the American Journal of Physiology. Dr. Valtin is a kidney specialist, and has also done 43 years of research on the osmoregulatory system.

He was asked bye the journal to review all the scientific studies he could find on the subject, and "he concluded that someone misinformed has been telling people to drink large amounts of water when most do not need to".

He basically says that "by drinking 8 glasses of water a day may do little more than make a person run to the bathroom" and "he hopes people will be relieved of the guilt of not getting enough water and of the expense of buying bottled water to drink throughout the day".

He also said that this study is "referring to healthy adults in a temperate climate leading a largely sedentary existence" and that "persons with certain diseases must have large volumes of water - kidney stones are probably the most common example".

Well, since I had surgery, they tell us not to use caffine,(appetite stimulant) or carbonated stuff (blows up the puoch), every thing else tastes funny, so all I drink is H2o. I usually drink about a gallon/day or more. I stop around 1900 so I'm not up all noc. Skin is great, no H/A, and I'm a cheap date for my husband.

First 24 oz. down, at least 24 more to go.

Give me water anytime. No calories...no caffeine...no problem!

But give me my 2 cups of coffee in the morning so I can kick my day into high gear! ;)

I've often felt revived and less fatigued after drinking more-- like a wilted plant being watered! I had heard the same thing from a dietician about fatigue caused by dehydration and also, headaches. I perspire a lot when I work out and always tried to hydrate well before hitting the gym. However, I often ended up with a headache a few hours after finishing and always thought it was related to lifting weights and muscle tension in my neck, shoulders, etc. Once I started really forcing fluids (more before and especially after the workout), my headaches became more rare. Also, our house doesn't have air conditioning so I'm constantly sipping water to stay cooler.

I also began drinking more water when I started on Weight Watchers two years ago. Once I got into the habit, I became more aware of thirst and I drink a ton in the a.m. after 8-plus hours at night without fluids. Also, I over-hydrate on the days before I work 3-11 because I NEVER drink enough on the job. I can drink 20 oz. before I hit the hay and never need to get up to "go" after a shift's worth of dehydration.

I mix water with a splash of fruit juice, and especially like adding a little bit of "Rose's Lime Juice", but I frequently take it plain, too. (We have a PUR water filter because of possible lead in the pipes of our 70 year old house.)

This subject is very near and dear to me, and I feel proud to share with you my essential life support. water has to get to three distinct compartments in my body. And it's not like drinking is filling up a gas tank. It takes time and other factors in order for water to reach where it has to go. Water occupies my: blood, cells and intastital spaces (sp) eyes, joints, brain.

When i do work, I crave water. If I do really hard work, I get the cravings really bad. That is when water makes me high. Nothing gives your body the rush of guzzling lots of water when your thirsty.

So I incorporate my water consumption into the workout. It comes at the end, after I come out of the steam room. I workout at least 4 times a week, not pushing myself either. I drink 1.5 liters in the big mouth Aqua-fina bottle. Of course I refill it.

It's a neat feeling to have worked out (sweat) and then go into the steamroom and KNOW that water is waiting for you. I carry it with me in the steamroom so it gets a little warmer since it's cold out of the fountain. After 5-10 minutes in the steam room, I can down the whole thing, mmmmmm. 1.5 liters of water weighs 3.5 pounds. So I gain 3.4 pounds right there on the spot. Sometimes I weigh myself before steam and water, then after, and I usually sweat about a pound of water. So cool because I can monitor/learn about a human body.

On days i don't work out, I still drink the 1.5 liters of water, all at once. Before you thinks thats abnormal, the human stomach has 4 liter capacity. Downing 1.5 liters is less than 50% capacity, and if i've been NPO for at least 2 hours, its okay. I like to drink my water at room temperature. The action of swalling succesive gulps of water takes some practice, at first. Sometimes I consider it to be flushing a toilet, because the body does make wastes, and we also sometimes put wastes into it. If you only sip water, and don't drink it, you'll never have a good flush, yuk!

And, sometimes I'll go a day or two without drinking any water. The first day is fine, I still void normally, and the same amounts. after 24 hours my body is still the same, maybe voiding a little less, day three is when its dangerous, I won't describe it except that i can feel myself getting smaller in size when laying in bed :-(

I don't believe i drink enough water. The body requires 1 cc of water for every 1kcal burnt. I'd need to consume about 2.75 or 3 liters. I get water from most of my food/fruit. It's so fun, but when I am properly hydrated, I don't get the cravings to drink anything else, and I feel good. My nephrons are loving it, and so is my plasma, as well as my CSF. And I like my voids to always be pale golden :-)

I can't believe I told all this.

I only drink bottled water........that's my basic beverage.....drink very little of any other kind.....have been this way now for 32 years. I carry water around with me everywhere I go.....even in the house...so I can drink it on demand. :chuckle

I got in the habit of drinking bottled water from all that traveling I did as a military family member, then as a traveling nurse. So.....now I'm totally addicted to bottled water......hate tap water. I drink water because I want to.....not because some article or news event says I should. I don't get into all those statistical thingys since by the time they are all printed out for people to read, some other scientist has come out with an entirely new theory. So.....why even read that stuff! :rolleyes: :)

Usually drink 3L QD, really makes a differance to my skin. Colleen, your hootie-hoo!!! Too funny!:roll

this is drinking too much water
