Seawater contains salt. When humans drink seawater, their cells are thus taking in water and salt. Therefore, to get rid of all the excess salt taken in by drinking seawater, you have to urinate more water than you drank. Eventually, you die of dehydration even as you become thirstier..
Also, can you filter ocean water to drink?
Desalination is a process that removes dissolved minerals (including but not limited to salt) from seawater, brackish water, or treated wastewater. And, of all the Earth's water, 97 percent is salt water, only 1 percent is fresh water available for humans to drink, and 2 percent is frozen.
One may also ask, why can't we purify sea water? Seawater is forced through a semipermeable membrane that separates salt from water. Because the technology typically requires less energy than thermal distillation, most new plants, like Tampa's, now use reverse osmosis. Pumping this supersalty water back into the ocean can harm local aquatic life.
Secondly, why sea water Cannot be used for drinking?
Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body normally gets rid of excess salt by having the kidneys produce urine, but it needs freshwater to dilute the salt in your body for the kidneys to work properly.
What happens if you drink ocean water?
Seawater contains salt. Human kidneys can only make urine that is less salty than salt water. Therefore, to get rid of all the excess salt taken in by drinking seawater, you have to urinate more water than you drank. Eventually, you die of dehydration even as you become thirstier.

Why can't we drink salt water osmosis?
If you're consuming seawater, the results of osmosis are spectacularly disastrous. However, human kidneys can only produce urine that's slightly less salty than saltwater.
