a thirst,afterall its the throat area that feels dry and tickly
why isnt a cup enough "to whet your whistlel"as they used to say ? but when i drink water i keep on guzzling it down till my stomach has had enough,and not a minute before otherwise im still dry/thirsty!But once i have had my full quota of water then my thirst is quenched at the throat and stomach ,and im refreshed once again.
Answer:
I think it's like food, it takes a while for you brain to receive the signals that you've had enough
we are supposed to drink 8 glasses a day so go figure from that standpoint.
Water is absolutely essential to live. Humans are about 2/3s water. You can go without food for much longer than you can go without water so thirst is a very strong biological need. Just a few important functions of water are it delivers oxygen and nutrients to different parts of the body, removes toxins and waste from the body, and regulates body temperature through perspiration. You're body cannot store extra water for later use like it can food. Extra calories (energy) are converted to fat and stored until the energy is needed. But extra water passes through our body.In short, I would guess that it's the strong biological need and the body's inability to store water for later use that cause you to drink so much water, not a little cut. After all, it's not your throat that tells you you're satisfied - it's your brain. And you're brain knows the importance of H2O!
