Why can't seawater quench your thirst?

Imagine that you are stranded on an Island with nothing to drink there is saltwater, but will you drink it or will you not. Well you shouldn’t because it will just make you dehydrated. You are better off just not drinking at all, you will also have a chance of living longer if you do this. But still why does this make you dehydrated, the main reason is because it has salt in it. Salt water also has way to much salt in it for the kidneys to produce urine. If the kidneys tried to do this you would die of dehydration.

Why can’t the kidneys produce urine from salt water? The urine that the kidneys produce is much less salty than salt water to begin with. The more you drink the thirstier you get and the harder it is on your kidneys. If you drink a small amount it’s not going to kill you though. Sodium is needed in our body for us to live, but salt is sodium and other unhealthy things like chloride. Another thing bad about sea water is it could have chemicals in it like oil.

Besides the kidneys another thing in our body needs fresh water to live. In our body cells need fresh water because it is a major part in our bodies. The salt water will pass through the cells and do nothing causing you to dehydrate. All of this is a process called osmosis. Salt water is also heavier than the water inside the cells. Salt water is also very unhealthy for you in large quantities it increases the salt in your body, it could even cause your blood pressure to raise also unhealthy. But the bottom line is a person who drinks salt water is just making themselves thirstier!

Salt water has many unhealthy effects on our body mainly dehydration. Many parts of our body cannot handle it in large quantities as well. If you are stranded on an Island like Vicki and Andy you are better off just not drinking anything. If necessary you should wait for help to come. It may be hard to resist, but salt water kills by not getting water to any parts of your body. Your body will go haywire and attempt to find any water molecules in your body. Salt water just makes everything a whole lot worse.
