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
Basically there are several ways for your body to tell you to stop drinking. Some are short term and act within minutes, and some are long term and take awhile to work.
Basically, you feel less thirsty quickly after drinking for two reasons: 1. Your mouth is wet. This tells your brain you are drinking water. And 2. Your stomach expands. Sensors in your stomach tell your brain you have had a good amount of water and to stop drinking for now. That way you don’t drink too much and hurt yourself.
Long term, if you drink enough water your blood becomes less salty, which tells your brain you have had enough water.
