The obvious solution is to change the contest to gatorade drinking, rather than water.
I can say the same thing about running long distances People do a lot of unnatural things. Working night-shifts is one. Typing on keyboards getting RSI, but continuing to type despite the pain, is another.Any way you cut it, drinking down 2 Liters of water in a short amount of time just isnt natural, and doesnt feel good, infact it feels terrible.
Much of what is sense is learnt behaviour, and I think people learn to ignore a lot of natural responses. The common sense, the common knowledge about what's bad for you, doesn't extend very far to working with one's own body balance. DemoCoder presents a good explanation of why people should know better, but that's all from scientific education. There isn't much people take out of their schooling into every day lives. Typical common sense doesn't rely on schooling, but more experience. eg. If you pour petrol over yourself and then start smoking, you'll get burnt. Common sense tells you not to do that because you know it's bad, without needing a scientific understanding of hydrocarbon combustion. Upsetting the electrolyte balance by consuming too much water isn't any common knowledge you get from everyday experience. Knowing when to listen to body's warning signs, and when to ignore them, also isn't common knowledge, perhaps because in most cases those warnings are ignored, no real harm comes of it (at least, not acute harm).Thats common sense.
She was allowed to piss. Granted it meant she'd be out of the contest. No one forced her to do anything she didn't want to do.
Doctors always tell you to drink lots and lots of water, they never limit it, how should a common man/woman know about the dangers of this?

That is by no means always the case.I'm under the impression the symptoms of water intoxication are evident early on, instead of death hitting you like a freight train. The process seems like it would be drawn out long enough for you to know you were in any real danger.

Well, that's going in the right direction but it isn't really a dilution per se that is the problem, but an actual removal of vital electrolytes from circulation [edit - well, the problem is the dilution, but the mechanism isn't simply adding more water to a fixed ion amount, but ion removal, which might not be as intuitive... see explanation below]. Specifically, our kidneys function to maintain salt and water balance in our bodies (among other functions), and they accomplish that through selective permeability of certain ions, particularly sodium. But balance is dependent on reasonable amounts of both salt and water intake to begin with... when our water intake and bodily content is too high (which in itself might result in systemic edema, hypertension, hypervolemia, etc.) our kidneys are called in to action to remove water from circulation.So let me get this straight, the over-intake of water produces a dillution of sodium in the blood, right? So essentially your blood poisons you? Or is it more along the lines of water is replacing vital nutrients and electrolytes therefore acting as a spaceholder that's taking up space of valuable substances?
That's an effect of the hyponatremia, but I'm not sure if that is the causative mechanism of death in all cases, or in what percentage of cases.My guess would be that chloride homeostasis is lost (via NKCC1 and KCC2). As a result, Gabaergic inhibition would become excitatory across all inhibitory interneurons, leading to wide scale eleptiform activity causing death.
But in audio recordings which have been posted on the Internet, the DJs are heard joking about contestants dying of water intoxication, even referencing the death of Matthew Carrington, a student who died after drinking too much water during a fraternity hazing. A caller, who identified herself as Eva, also phoned in to the show to warn that the stunt could kill, but she was dismissed by being told that contestants had "signed releases, so we're not responsible."
