This claim, that a human can drink too much water, is true. Before this claim is addressed though, we have to identify what "too much" water is. My conclusion, and what I am basing this response on, is that drinking "too much" water is drinking enough to kill you. According to University Hospitals, an Ohio based hospital conglomerate, drinking too much water can lead to death. This article stated a specific instance in 2007 when a radio show contestant died of hyponatremia (water intoxication). After reading this I did external research where I confirmed that Jennifer Strange did pass away after drinking almost two gallons of water during the duration of the radio show contest. There are many other examples of people dying of hyponatremia and because of that, I confirm that this claim is true.
