I get that our body needs water. But why does the thirst response almost always overestimates the amount of water our body actually needs, thereby leaving excess water that comes out as urine? How come our body doesn’t tell us to drink just the right amount of water that it needs? Why does yellow pee mean dehydration when the fact that there was enough excess water to produce urine means that you’re probably not dehydrated anymore?

Urine and feces are our body’s way of removing toxins and unused food/drinks. In urine, the yellow is the color caused by what’s being excreted. When we drink more water, our urine gets diluted. Hence the more we drink the lighter it gets. Also, our bodies don’t really “over estimate” the amount of water we need. After a certain point, it should stop signaling thirst (unless meds/other health circumstances are relevant).
