Your stomach lining is a super-sensitive sponge. It needs hydration to produce mucus, which protects it from its own powerful acid. Without enough water, that protective layer gets thinner and thinner.
Now imagine that acid, which is strong enough to dissolve a nail, touching raw stomach tissue. Ouch. Your body responds to that irritation by sending nausea signals straight to your brain. It’s like a burn alert from the inside.
This is why a hangover feels so rough—you’re dehydrated and your stomach is literally getting pickled. The combo is brutal, but fascinating from a survival standpoint.
