    That always struck me as ridiculous. There's no way I can consume 20 oz liquid and end up more dehydrated than I was, unless it's salt water or I sweat it all out through my pores. Fuckin' pop sci.

Salt water makes you more hydrated. There's a reason Gatorade is packed full of it.

See, exactly. Even I'm wrong.

(I was thinking about how drinking ocean water will kill you when I made that remark.)

Well you're correct in that regard. The salinity of seawater is higher than the salinity in your body. Therefore, to excrete it, you need extra water (since the salinity of urine can't exceed the salinity of your body), which does dehydrate you. Like many chemicals, salt is essential for life, but too much is toxic.
