How many people have died from water intoxication?

Water intoxication, also known as hyponatremia, is a rare condition that can lead to death, but specific statistics on fatalities are hard to determine. While it’s estimated that a few dozen cases occur annually in extreme circumstances, such as endurance events or excessive water consumption in a short time, the overall number of deaths is quite low compared to other causes. Most cases are preventable with proper awareness and hydration practices.
