    Sea water contains a lot of salt and other minerals: minerals that the body can't use (at least in those amounts) and must get rid of. It expels these through urine. The amount of water your body eliminates in getting rid of these minerals is more than you retain from drinking it. So, you can dehydrate and die.

    Humans can't drink salt water because the 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 salt water, you have to urinate more water than you drank, so you die of dehydration.

    It is full of things struggling for survival that are more comfortable in the water then we are?

    Or do you mean drinking it? Osmosis, the passage of water across a membrane from areas of higher to lower concentration causes our water to move into sea water, because with the salt in it there is less water in the seawater then their is in our bodies. So drinking sea water dehydrates us.

    conversing in terms of survival, salt interior the sea water dries the water on your physique and positively, as a substitute of providing you with extra water, it makes you prefer extra water, however the extra you're taking, the thirstier you get.
