How can someone die from drinking too much water?

In January 2007, hours after competing in a radio station contest to win a Nintendo Wii, 28-year-old Jennifer Strange was found dead in her California home. The station’s “Hold Your Wee for a Wii” challenge awarded the game system to the contestant who could drink the most water without having to take a trip to the bathroom. According to preliminary autopsy reports, Ms. Strange apparently died from drinking too much water too quickly, resulting in a condition called water intoxication.

At its most basic, water intoxication occurs when a person drinks so much water that the other nutrients in the body become diluted to the point that they can no longer do their jobs. You’ve probably heard the term electrolyte before, whether in reference to sports drinks (which provide electrolytes in addition to fluids) or to certain conditions, such as bulimia or diarrhea, that cause dangerous “electrolyte imbalances” in the body. Electrolytes are simply salt ions (atoms with an overall positive or negative charge) that cells use to move fluids and nerve messages into and out of cells and throughout the body. Without electrolytes, the body can’t function (see What are electrolytes? for a more detailed description). Water intoxication causes an electrolyte imbalance that affects concentrations of the ion sodium, and it leads to a condition called hyponatremia. Read more
