stupid question,how easy is it to die from water?

It's not easy to do. You would just have to keep going and going and you would definitely feel "full" before you got to that point.

I'd pick another thing to worry and become anxious about. Really.

You'd have to drink like 2 gallons of water, maybe more, within an hour to even begin to worry about that. And before then you'd most likely vomit and stop. If you're just drinking a little too much your urine will be clear. If you're drinking 8 or 12 cups of water a day there is nothing you need to worry about.

Or in short: Don't enter any water-drinking-contests and don't drink only water if you're running a marathon, and you'll be fine.

A healthy adult can process up to 15 litres of water a day if drank over the day.

8 - 12 glasses is recommended and more if a warm day. You are going to spread it out over the day as I think anyone would find it hard to drink it all in one go.

Water intoxication is really very rare so I don`t think you should worry about it. It is most likely to happen to babies or athletes if at all.

Just enjoy your water :-)

You'd have to basically drowned your body. I mean, unless you're a total freak, you're not going to do that. I cold see hat happening to someone with severe OCD or something. But, no one normal would ever do that to themselves. You'd feel it start to suffocate you before you did yourself in.

While its possible, it's more likely that you'll win the lottery first.

It isn't how much water, it's how fast. If you drink water over the course of a day, the kidneys can process 15 L of water. I doubt you drink anything near that amount. You would probably stop when you felt full or bloated.

As for soda, there is nothing of nutritional value in soda, so why even drink it?

Yes, you can drink too much of any liquid.

I think water poisoning mainly happens to children? Wouldn't an adult have to drink an insane amount of water to die from it?

It's not a stupid question and drinking too much water can cause significant problems:

I've personally seen a half dozen people in 20+years get into trouble. One died. So it's not common, but here's briefly what happens.

The first case was a runner in the Houston Marathon. He replaced his fluid loss (sweat/salt/water) with pure water instead of water and electrolytes. He drank a lot of water during the run. At some point he convulsed (had a seizure). He later died from Central Pontine Demyelinolysis (stripping of the coating off part of the brainstem) from rapid electrolyte shifts.

The second case I recall was a gentleman at M.D. Anderson Hospital who had a prostate biopsy because he was told by an outside hospital that he had cancer - it turned out he didn't. At any rate the sugeon told him to drink plenty of fluid to flush himself out..so he went right to the cafeteria and drank glass after glass after glass of water. Till he had a convulsion.

In both cases it was the rapid intake of plain water - and in the first case loss of salt too - that led to the rapid changes and drop in Sodium (normally 140 mg/dl) but in both these individuals their sodiums dropped markedly - first case to 108 and in the second case to 118 mg/dl.

So it does happen, but it's rare.

To borrow from Wikipedia:
At the onset of this condition, fluid outside the cells has an excessively low amount of solutes (such as sodium (hyponatremia) and other electrolytes) in comparison to that inside the cells causing the fluid to shift through (via osmosis) into the cells to balance its concentration. This causes the cells to swell. In the brain, this swelling increases intracranial pressure (ICP). It is this increase in pressure which leads to the first observable symptoms of water intoxication: headache, personality changes, changes in behavior, confusion, irritability, and drowsiness. These are sometimes followed by difficulty breathing during exertion, muscle weakness, twitching, or cramping, nausea, vomiting, thirst, and a dulled ability to perceive and interpret sensory information. As the condition persists papillary and vital signs may result including bradycardia and widened pulse pressure. The cells in the brain may swell to the point where blood flow is interrupted resulting in cerebral edema. Swollen brain cells may also apply pressure to the brain stem causing central nervous system dysfunction. Both cerebral edema and interference with the central nervous system are dangerous and could result in seizures, brain damage, coma or death.[4]
