You lose some sodium in sweat, so if your sweating heavily, then you could possibly lose some sodium, but that simply means you need to mix an electrolyte into your water, or eat something that contains some sodium. A hand full of GORP made with salted peanuts every 20 minutes or so is probably better for you, then not getting enough water.
