On the other hand I remember a journalist trying to track down the
basis for the various recommendations of how much water you're supposed
to drink, like 8 eight ounce glasses a day. After a lot of searching,
he could find nothing, no studies, etc to back it up. And he observed
that he also could not find any cases where people who had access to
water had died from a lack of water. He did find cases where people had
died from drinking way too much water, typically as a bet or challenge.


The key is "access to water" Every summer you hear of some athlete
passing out either from self imposed regimen or an over zealous coach.
Not just water, you need electrolytes too.

From Google:
How many football players have died from heat stroke?
Since 1995, three football players a year on average have died of heat
stroke, most of them high schoolers, according to the National Center
for Catastrophic Sport Injury Research, which tracks football injuries
and deaths.

I'd also say heatstroke and not having enough water are not the same thing.
You could have lots of water and still have heatstroke, especially from
strenuous exertion in high temps.
