Why does your body get thirsty for water?
You've just run around the block, or eaten something salty, or maybe just woken up on a hot morning. Suddenly your mouth feels dry, your throat a little scratchy. Your body is telling you something important: "Hey! We need water in here!" But why does that feeling happen at all?
Here's the thing: you are mostly water. About 60% of you, actually — more than half! Your blood is water carrying supplies to your cells. Your cells themselves are little water balloons doing chemistry. Even your brain floats in water. Water is the liquid that makes everything in your body work.
