The Mayo Clinic and the Berkeley Wellness Letter are generally considered to be reputable sources. I don't think there's a myth or a conspiracy, it's just a bit of mistaken information that unfortunately became a catch phrase.

As for the lady from the radio station, it wasn't the excess water that killed her, it was the shortage of brain.
She can't be held up as proof of this "water conspiracy" |
I think the point is that there is no proof. |

Drinking too much water too quickly causes the sodium levels to drop in the system, and can thereby cause heart failure. The electrical currents need the sodium to conduct.
So, too much can harm you. |

| Or maybe you drink 8 glasses of water/day for many years. When you get old, you can't bring yourself to drink so much. Your body is so used to the water that when you lessen the consumption, you just wither away and die. |

| anthony robbins the guru said in his book 'unlimited power' that we don't need to 'flood' our body with water i.e. the 8 glasses or more a day myth, but emphasizes the importance of 'when' we should drink water i.e. before meals and not straight after. |

Well the cells aren't the first to determine what happens with excess water. The kidneys are responsible for excreting excess water. I'm not suggesting an extra glass of water or two will kill you. It's just that in any given population, some people make the assumption that if x amount is good then x^2 is better. The radio station woman may well have lived if she exercised some critical reason, indeed, but the fact remains what killed her was drinking too much water in too short of a time.
And as the other poster pointed out, I'm not offering proof. I'm asking for proof. If a doctor says I need to take 1000 mg of vitamin C a day, I'd want to know based on what evidence. I was aware that the 8 glasses of water a day story was without scientific support (much like the claim we only use 10% of our brain). I would be very skeptical of a doctor who was simply quoting known medical myths. |

I've never been told by a Doctor to drink 8 glasses of water a day. Perhaps Drs. know this "claim" is without warrant, but refuting it is at best pointless.
Ultimately, the woman died of too much water. but by that token, if I sewed my arsehole shut and ate a bunch of carrots I would eventually die.
Should we then warn people of the hazards of eating too many carrots?
Is drowning in a lake also proof that too much water is bad for you? |

You must be eating a terrible diet. I doubt all that water will save you, if you don't start getting some fresh produce into your body right away.  |

Everything is cells. Your kidneys are just a bunch of cells who rallied together to do what kidneys do. before water reaches these cells it encounters a bunch of other cells that rallied together to be your tongue, mouth, etc.......
each cell takes what it needs and lets the rest pass.
I understand your argument that there is no proof for this myth,
And that people don't know what they're doing and just sheepishly follow what they heard.
But there is also no proof to prove this myth wrong.
What would be valid proof in your mind? |

The proof to prove the myth is wrong is a scientific study that determines how much water a body needs every day to replace the water lost. I'm rather happy to report that in the 100 years modern medicine has been around, the research has finally been done.

| These results demonstrate that water turnover is highly variable among individuals and that little of the variance is explained by anthropometric parameters. |
In short, 8 glasses may be be right for some, may be too much for some, and may not be enough for some.
| Quote: |
| There was no evidence of dehydration in the 70- to 79-year-old group, despite the majority of the individuals having intakes less than the commonly used suggestion of eight 8-oz glasses of water each day. Furthermore, recommendations to increase fluid intake to eight 8-oz glasses of water in the elderly may not be prudent because the elderly have an elevated risk of overhydration due to the weakened physiological movement of water through the system. Instead, the researchers suggest that fluid intake for the elderly be increased during periods of acute thermal stress. |

Each body, i.e. compilation of cells , is different, and therefore has different needs. (noted) On average, or in general, or to be on the safe side, drink 8 glasses of water a day.
What's the problem? |

"The proof to prove the myth is wrong is a scientific study that determines how much water a body needs every day to replace the water lost."
The oppositre is true.
Water lost, really means water not needed. so your body gets rid of it. If your body, i.e cells, needs it, you won't get rid of it. We're not in a fight to replace lost water, we get rid of water we don't need.
We all, i.e. cells, have excretory sytems for just such purposes.
Again, what is it that you are arguing?
Another random post (scientific study link) supposedly proving your point.
It's nonsense. Have you really studied this issue before reading this post? |

We don't lose the water the body decides it doesn't need. When we breathe we lose water because the air absorbs water. This is why our clothes dry when we hang them out to dry. Our body needs to use water as a medium to pee 'n' poop. We can't simply excrete the chemicals we don't need without using water as the medium to excrete them. Our body expends water to regulate temperature. Water lost is water needed. But need for a purpose.
What I'm arguing is her statement about how many glasses of water we need to drink a day is not based on actual research. It's an urban legend (or medical legend) people pass along but has no basis in science. It's like someone saying you need 100 mg of vitamin c every day. Based on what evidence. There can be no doubt we need vitamin C. But a doctor, like the woman writing the article, would seek to provide a scientific underpinning. I would find it disturbing if any doctor was quoting medical myths ("We only use 10% of our brain!") and I would be less inclined to accept that doctor's advice.
As it turns out, current research indicates you can't make such a blanket statement. The study "proves" the 8 glasses advice false. As the study indicates, for older people, over hydration could have negative effects. |
