Okay, this is my favorite fun fact. Ever notice how your mouth tastes funky in the morning? That’s bacteria! This bacteria produces sulfur compounds (hello, morning breath). When you drink water, you wash those compounds down into your stomach.
Your stomach looks at this bacterial cocktail and goes, “Uh, I didn’t order this.” It can trigger a mild rejection, which is that nausea. You’re literally swallowing your own “overnight party” leftovers. Gross but fascinating, right?
This is why brushing your tongue before drinking might help. It’s like sweeping the floor before the guests arrive. You’re not sending a weird bacteria buffet to your stomach, so it has less reason to rebel.
