Water intoxication causes hyponatremia, which can lead to coma and death

Drinking too much water, called water intoxication, affects the brain, according to Medical News Today. It is dangerous because the amount of water in the blood increases and electrolytes such as sodium are diluted, causing the cells to swell.

These electrolytes help the body function normally by maintaining fluid and blood volume, says the U.S. Centers for Disease Control and Prevention.
