Yes, drinking ocean water creates a hypertonic environment for your blood cells, causing them to shrivel as the concentration of water is equalized. On the other hand, too much water creates a hypotonic environment, and as the water enters the cells, they basically burst (cytolysis?).

Feel free to correct anything.

Yes, you can drink too much. If the water has some chemicals in it, you can get sick from those, or if you drink about 2 liters in 10 minutes, you'll die.

Soda bottles are 2 litres and I don't find drinking that quantity to be harmful if I was very thirsty.
 
It's almost impossible to kill yourself by drinking water. You have to drink a ton of it without your body, uh, relieving itself. It's the exact opposite of dehydration--too little sodium in your cells.
 
You'd have to drink about a bathtub-sized amount of water in about two minutes to possibly die from overdrinking. ;)
 
I am just out on measurements today. I actually said I was about 1 1/2 Liters tall.
 
Here in Maine, I think, there was a radio station that had a contest called "Hold Your Wee For a Wii". People had to constantly drink water and weren't allowed to go to the bathroom. I believe one woman died from drinking too much water, no idea how much though.
 
Wikipedia
Water intoxication (also known as hyperhydration or water poisoning) is a potentially fatal disturbance in brain function that results when the normal balance of electrolytes in the body is pushed outside of safe limits by water.

Normal, healthy (both physically and nutritionally) individuals have little to worry about accidentally consuming too much water. Nearly all deaths related to water intoxication in normal individuals have resulted either from water drinking contests, in which individuals attempt to consume more than ten liters over the course of just a few minutes, or long bouts of intensive exercise during which electrolytes are not properly replenished, yet massive amounts of fluid are still consumed.

I think it means that if you drink enough water to drastically change the sodium levels in your body you will lose ability to transport oxygen. that's why sports drinks contain a fair amount of salt.

Here's mine:

- People always say that it's healthy to drink lots of water. However, the other day, I drank 3 litres of water between 8.20am-15.00pm. Suddenly, a friend of mine start talking about the "dangers of drinking too much water". So, can one drink too much? What'll happen if you indeed drink too much?

It requires you to drink waaaaayyyy more than just 3 liters in 7 hours. More like 6 liters in 1 hour. A.K.A. enough to make you throw up if you drank it fast enough. so your friend should get a medical degree then proscribe treatments.

I regularly will drink nothing for a day then the next day i drink about 80 fl. oz. over the course of a day.

And why marathon runners, racecar drivers, and decathletes will eat bananas. Being incredibly high in potassium, it will counteract the gallons of water they drink during their tasks, and also prevent cramps.

Exactly. Like I said, it's almost impossible to drink yourself to death on water. You have to chug like crazy, and not allow your body to relieve it. Marathon runners can be at risk, but there are many other factors related to running 26 miles that aggravate the situation, not just drinking too much.
 
I used to work as a bouncer and I could drink 3 litres of water in less than an hour, and I'm still here.

The amount fo water you'd have to drink to kill yourself is about 18 litres in less than 6 hours... do the math as to how much it should be in an hour.

I just did it and I'm not dead.

I did that about four years ago, on a class-trip. Each group had to drink a whole 3-liter bottle as quickly as possible - so, being quite thirsty, I drank a solid 2/3rds of the bottle. :p

But how high was the alcohol-percentage? ;)
 
Ultra-filtered, pure water - laboratory grade - will kill you very quickly if you drink it.
 
It does exactly what the people in this thread are talking about - strips salts out of your body by osmosis, resulting in nerve dysfunction - since your nerves require potassium to function. Enough of it will stop the nerve impulses to your heart.
 
To what degree is distilled water bad for you, then?

or if you drink about 2 liters in 10 minutes, you'll die.

I have drank 2 litres of water in under 10mins on a few occasions, had no effects. I did do some reading up on it awhile ago and it really depends on how healthy your kidneys are (from memory, which maybe off from drinking too fast :p)
 
Not to interrupt this nice water > poison discussion but I've 2 questions.


* Is there a centerpoint on a sphere?

* If someone travels to another planet, will he/she ages as fast/slow like on earth? Or does aging depends on which planet you're ao?

Not sure if I got the proper words, but wouldn't a centrepoint of a sphere be exactly like the one on a plain circle? Spheres have a radius, so their centre is the connector between the radii?

Depends. If you count the "years" different, then obviously yes - a year on the moon is just 30 days, and a year on earth is 365...

However, if you still count them the same, then still yes - to a smaller degree. Time, if I recall correctly from a Scientific American article, gets slightly stretched with gravity - so theoretically, time actually passes faster on a heavy planet.

Right, there's a center point of a sphere, but not really on a sphere
 
What I mean is, if someone is on another planet, will this person die on the exact same moment as he/she had stayed on earth. Don't take in account all the things that could happen to this person. Just look at it in perspective of genetically predetermination (bad English, I know but I hope you know what I mean).

Let's say this person lives on "Alpha Centauri", and his/her twin lives on planet earth. Lets say that it is genetically predeterminate that these twins die at the exact same age. Lets say that, if they had both stayed on earth, they both would die at the age of 70 years, 2 months, 3 days, etc... . If one of them lives (he/she gets there in his/her lifetime because it is technically possible) on Alpha Centauri, would he/she also die at the age of 70 years, 2 months, 3 days, etc... (earth time). So exactly at the same moment as his/her twin on earth? Pure a theoretically model!


That's what I thought, there is no center point on a sphere.

Someone's been hitting the ganja and thinking deeep....

But seriously that is a pretty interesting question, I'll be keeping an eye out on this thread.
