A colleague on mine who once ran an ecological survey in the desert mentioned that her fluid of choice for extreme dry heat was V8. Pretty much anything else would cause horrible salt deprivation.

I read somewhere about surviving being stranded at sea, that losing salt is not really an issue. The body doesn't care about how much salt it has, only what the concentration of salt is in the blood. As you lose water due to sweating, even through sweat does have some salt, overall the body is losing more water than salt, and therefore blood salt concentration increases. Of course over long periods you will deplete your salt reserves, but this will take a while. So drink more water than V8 or gatorade to keep you balanced.

  Drinking sea-turtle blood has been key to a few stranded at sea people's survival.

    I was wondering how fish juice is defined, and it sounds gross: > The most critical need, hydration, would be solved by squeezing the fluid from the fish and collecting rainwater, supplemented with small doses of seawater that did not exceed one litre a day—one tablespoon at intervals of 20 minutes, allowing the saliva to dilute the salt in the mouth.

    That's assuming you are drinking water, which parent was not.
