You would have to drink an extreme amount for it to be too much water-use the search function in the forums and you'll see this come up a million times.

I know wikipedia is not the best source, but I've spoken about this with a doctor and what the wikipedia say in this case is mostly right.

Diabetes insipidus (DI) is a condition characterized by excessive thirst and excretion of large amounts of severely diluted urine, with reduction of fluid intake having no effect on the concentration of the urine. There are several different types of DI, each with a different cause. The most common type in humans is central DI, caused by a deficiency of arginine vasopressin (AVP), also known as antidiuretic hormone (ADH). The second common type of DI is nephrogenic diabetes insipidus, which is caused by an insensitivity of the kidneys to ADH. It can also be an iatrogenic artifact of drug use.
Although they have a common name, diabetes mellitus and diabetes insipidus are two entirely separate conditions with unrelated mechanisms. Both cause large amounts of urine to be produced (polyuria), and the term "diabetes" is derived from the Greek name for this symptom. However, diabetes insipidus is either a problem with the production of antidiuretic hormone (cranial diabetes insipidus) or kidney's response to antidiuretic hormone (nephrogenic diabetes insipidus), whereas diabetes mellitus causes polyuria via a process called osmotic diuresis, due to the high blood sugar leaking into the urine and taking excess water along with it.
The incidence of diabetes insipidus in the general population is three in 100,000.

Excessive urination and extreme thirst (especially for cold water and sometimes ice or ice water) are typical for DI.[2] Its symptoms are quite similar to those of untreated diabetes mellitus, with the distinction that the urine does not contain glucose and there is no hyperglycemia (elevated blood glucose). Blurred vision is a rarity. Signs of dehydration may also appear in some individuals, since the body cannot conserve much (if any) of the water it takes in.
The extreme urination continues throughout the day and the night. In children, DI can interfere with appetite, eating, weight gain, and growth, as well. They may present with fever, vomiting, or diarrhea. Adults with untreated DI may remain healthy for decades as long as enough water is consumed to offset the urinary losses. However, there is a continuous risk of dehydration and loss of potassium.

I just find it difficult to read a study on a site called "fit sugar" about how you should drink less water and more sports drinks... not saying they are wrong, but it seems a little fishy...

You're unlikely to drink so much water that it's dangerous.

But, you don't need to drink 64 ounces of water a day, either. The only time people with ordinary health have to worry about their fluid intake is when they're in extreme heat or running a marathon or something. If you just drink beverages when you're thirsty, you will be fine. All that stuff about extra water "flushing" out your system is nonsense.

Furthermore, coffee, tea, and other beverages that contain caffeine will not dehydrate you. Your body will still net a gain in fluid in spite of the mild diuretic effect of caffeine.

From the article:

"To prevent water intoxication, don't consume more than 34 ounces of water per hour. When working out for extended periods of time, you may want to drink a sports drink that contains electrolytes."

This is excellent advice, if a tad conservative, but it does point out how minor a problem this really is. 34 ounces of water an hour is A LOT of water to drink in an hour, and if you're eating anything with electrolytes in it during that period you could probably safely double that water amount without worries.

Water intoxication is a real problem - if you're sweating profusely and making no effort to replenish your electrolytes, and drinking copious amounts of water. There are actually deaths that can be directly attributed to water intoxication (one of them is a young military recruit who ran in battle dress all day in Florida in the middle of the summer, then drank gallons of straight water to rehydrate - he actually died of hyponatremia).

For most of us, this is not a problem in our daily lives. The human body can process several GALLONS of water a day without ill effects, and most of us have no problems with too low sodium. In fact, I don't know about you but I struggle with the opposite problem!

Look, if you're concerned about the amount of water you drink, drop the silly 8 8oz nonsense and just check your pee. If it's light yellow or clear and dissolves readily in water, you're drinking plenty. If it's darker, cloudy in any way, or doesn't seem to dissipate readily into the tiolet (unless you have a medical condition or medications that can explain it) you need to drink more.

And if you are honestly concerned about water intoxication, get a bottle of Gatorade and have a 2 ounce glass of it twice a day. You probably don't NEED those electrolytes, but they aren't going to hurt you.

And those few occasions when you are pushing yourself really hard (I'm talking something really outside your normal realm of exercise), you won't hurt yourself by rehydrating with diluted Gatorade. When I rode the Trek Across Maine (60 miles a day cycling in hills for three days) I mixed a little Gatorade in one of my two water bottles. It was an overreaction since I had a snack every 25 miles, but it didn't hurt me none.

This is an awesome post, thank you!! I don't think I drink too much- actually sometimes I don't drink enough...but I saw that article and then did the calculator and it says that for my weight and such I should drink 110 oz a day....I think that's insane.

migdalp

Good to know, thanks!! I intake 96 oz of water everyday and if I exercise I increase. But never intake so much in 1 hour.

Yes can overhydrate seen it plenty of times in the Army. Lol we would get in trouble when we didn't drink enough water and passed out from dehydration and also get in trouble when we drank to much and got all loopy and delerious.

110 oz of water a day is a lot. I'm 6' 3" and weigh over 200 pounds and I drink a little over half that.

But, to put any fears to rest, 110 oz of water a day is also well below the water-processing capacity of almost every human being on the planet, so 110 ounces is a bit of a waste of potable water, but it's very unlikely to hurt you in any way.
