Is There Such a Thing as Drinking Too Much Water?

I keep seeing articles stating that you can die if you drink too much water. I wondered about that, since it can be difficult to drink enough water, so how can you drink too much? When I researched this question I found the following information:

It can be possible to drink too much water; however the scientists are quick to say that it’s not too probable. One way could be if you drank too much while exercising (such as running a 26 mile marathon), but running that marathon slowly while drinking a great deal of water. Because your body was diverting it’s processing to other organs, the kidneys may not be able to deal with a great deal of water in a short period of time.

According to Web MD, you would have to drink gallons and gallons of water to drink enough water to kill you. http://www.webmd.com/fitness-exercise/water-intoxication
The actual problem with drinking too much water is that the sodium level in your body could drop; so you can’t die from drinking water, but from dropping your sodium level. What they’re saying is that if you were drinking a lot of water while sweating a great deal, the sodium level could be lowered. That being said, the ability to die from this is still considered extremely rare and if you’re a regular person, exercising at a normal level, you really shouldn’t worry. Here are some more links regarding this issue: http://www.mayoclinic.org/diseases-conditions/hyponatremia/basics/definition/con-20031445

So, go ahead and drink at least eight glasses of water a day or more if it’s hot out, or you’ve been working out. This is not anything to lose any sleep over. Stay hydrated!
