Lost in translation

There are all kinds of options in terms of fluid replacement drinks and one of the most curious brand names in that arena is a Japanese beverage called Pocari Sweat. The slogan is along the lines of "when you sweat, you need Pocari Sweat." But would you want a drink that is called Sweat? And along those lines the brand name options for diarrhea prevention beverages are endless. But maybe something here is just lost in translation.
