Can drinking too much water be bad for you?
Drinking very large amounts of water over a short period of time may be fatal. This was demonstrated in the infamous case of the "wee for a Wii contest" where contestants tried to drink the most water to win a Wii. One contestant died. The excess water dilutes electrolytes and causes water intoxication which can lead to electrical disturbances in the body resulting in erratic neuronal tranmission of signals which can cause death.
