Water: How much is too much?

I have always drank more than the recomended 8 glasses of water a day, usually before lunch. I like water, and often crave it, which I never thought of as a bad thing. Since starting back to daily work outs, I've been drinking close to 2.5 gallons of water each day. I even wake up because I need to drink. I have been tested for diabetes, and thankfully my sugars are normal.

My question is, how much water can you safely drink before it becomes bad for you?

    The kidneys of a healthy adult can process fifteen liters of water a day! You are unlikely to suffer from water intoxication, even if you drink a lot of water, as long as you drink over time as opposed to intaking an enormous volume at one time. As a general guideline, most adults need about three quarts of fluid each day. Much of that water comes from food, so 8-12 eight ounce glasses a day is a common recommended intake. You may need more water if the weather is very warm or very dry, if you are exercising, or if you are taking certain medications. The bottom line is this: it's possible to drink too much water, but unless you are running a marathon or an infant, water intoxication is a very uncommon condition.

    I don't think there's a set amount. "The recommendation from the medical field is to drink at least 1.2 liters per day[2] depending upon body mass. Water intoxication would only occur at levels far higher than that."

    But if you start feeling ill at all, I would cut back.

    I don't think there is a set number. If that is how much water your body needs you should listen to your body.

    I was wondering this myself not to long ago and I found this information which I thought was really helpful.

    Does drinking more water really help dieting? A small study says it may help you burn a few more calories each day. How many? About 50 calories per liter or quart of water. About 25 calories per water bottle-full of water. Mind you, that's only 5 M&Ms - plain, not peanut.

    Why Drink More When Dieting?

    Drinking a big glass of water whenever you feel hungry and before a meal or snack fills the stomach briefly and makes you feel fuller and stop eating sooner. Breaking down body fat and body muscle during weight loss produces wastes that must be eliminated through the kidneys. Drinking enough water is important to keep the kidneys functioning to remove these wastes. Popular high-protein diets produce more waste products from digestion, let alone from breaking down stored fat. Kidney function is even more important when on a high-protein diet. Drinking more water does not "flush fat." If the dieter is drinking plain water, he/she is less likely to be drinking something with calories in it.

    Drinking Water Briefly Increases Metabolism

    Drinking 500 mL of water (a half-liter or about a pint) increased the study participants' metabolism briefly - for about a half hour. In that time they burned an extra 25 calories. That's about a quarter of a piece of sliced bread, or 5 M&Ms. The researchers theorized that most of the effect comes from warming the water in the stomach. In the male participants the calories came mostly from stored fat, in the women it came from stored carbohydrates. The paper was published in the Journal of Clinical Endocrinology and Metabolism, December, 2003. It was conducted by researchers in Berlin.

    Eight Glasses of Water a Day?

    The study provides some support for the general recommendation to drink eight glasses of water a day while dieting. For most people that would add a liter or two to their regular water intake. The extra calorie-burn would be about 100 calories a day if drinking 2 liters (2 quarts or 4 water-bottles full) more than usual.

    Dangers of Too Much Water

    Don't start drinking an extra gallon of water a day - that can kill you, especially if you are fasting or eating very little. Water taken in must be in balance with body salt - electrolytes. The body needs to maintain salt balance or risk hyponatremia with heart attack and even death. Drinking too much water dilutes the salt in your blood and tissues - and can kill you. Healthy athletes have died from drinking too much plain water and not replacing salt. Dieters should not plunge into drinking gallons of water a day in hopes of burning a few more calories. Drink an extra few glasses, yes. But a gallon is too much.

    Drinking and Walking

    Exercise such as walking causes the metabolism to rise and body water to be lost through increased respiration and sweat. Walkers should drink a large glass of water an hour before walking, then drink about a cup of water every mile. When you finish walking, drink a glass of water. Guidelines for the marathon and half-marathon now say to "drink when thirsty" rather than pushing water, in order to prevent hyponatremia - drinking too much with replacing electrolytes.

    :huh: water i belive is all right if you drink it all threw the day:glasses: , but if you drink it all at once its bad
  • sounds like you're doing just fine (especially being tested negative, because i feel you there, i'm always thirsty but i dont have diabetes either). if you dont feel drunk (which you do when water intoxicated, it happened to me once <_< whoooops) then you're fine, the body processes water and it goes through you, gets what it needs and pees out what it doesnt :laugh: gross but true!!!

    you're doing fine! keep drinking that water! ^__^

    Ok, so I was thinking the same thing, and guess what? You can over dose on water. It happened to me, and the results are not fun.

    A few weeks ago I went into the Dr. because I've been having serious dizzy spells. They took blood and urine tests, did some other tests and asked about my eating/drinking habits, etc.

    She concluded that the dizziness was caused by the water I was drinking. I was consuming too much water which was washing down the nutrients I was eating. Since I'm only on a 1200 cal/day regimen, she told me I should be only drinking 4-6 cups a day instead of the 20 I had been....

    I've cut back on water, and still get dizzy 1-2 times per day (It was up to 10x day).

    Just be careful, and if you ever feel light headed or not normal, talk to your dr!!
