When the relative humidity is that high your sweat doesn’t evaporate properly because the air is already too laden with moisture. Carrying the water to drink would prevent you from dehydrating but not do anything to cool you down. If you bring it to douse yourself with it, that’s actually probably more of a waste as it still won’t cool you down but also you’re wasting water you could have hydrated with.
