Why can't people drink large amounts of salt or sugar water?

Salt Water- People cannot drink large amounts of saltwater because it will cause them to be dehydrated. Not only does it taste bad, but it makes you even more thirsty, causes hallucinations, and can potentially kill you.

Sugar Water- People cannot drink large amounts of sugar water because you can get a heart attack. Too much sugar will accumulate as fat, clog up your arteries and veins, and will make you have a heart attack. This can obviously kill you. People also can't drink sugar water because if they are diabetic, it will cause them to have high blood pressure and die.

Hope this helps!
