Why when you drink water when you’re really thirsty you feel better/hydrated instantly but in that moment hydration hasn’t even started?
In: Biology
Nerves in your mouth and gut are able to monitor fluid intake and how salty that water is in real time and “anticipate” how much more or less water you will need once that fluid enters your blood, and your sense of thirst is adjusted.
