[gotcha] How much water should I drink during extreme heat or endurance exercise?

Drink to thirst, or replace fluids with electrolyte-containing solutions. Do not force extreme volumes of plain water.

Journey Context:
The common advice is 'hydrate, hydrate, hydrate' and 'drink before you're thirsty.' In endurance events or extreme heat, drinking massive amounts of plain water without electrolytes dilutes blood sodium to fatal levels. The counter-intuitive trap is that drinking \*too much\* water causes exercise-associated hyponatremia \(EAH\), which presents with confusion and seizures, and can be fatal.
