Here’s a fun fact: your gut has its own nervous system. It’s called the enteric nervous system, and it’s like a second brain. Dehydration makes this second brain throw a tantrum.
It releases stress hormones like cortisol and adrenaline. These can trigger nausea as a side effect. Your own stress response is sabotaging you from the inside. Thanks, body. Real team player.
It’s a vicious loop, too. You feel sick because you’re dehydrated. Then you vomit, making you more dehydrated. It’s the worst game of ping-pong ever invented.
What About Exercise? Or Hangovers?
Ever finish a hard workout, feel amazing, then suddenly get queasy? That’s exertion dehydration. Your blood shunts away from your stomach to your muscles. Your stomach gets angry and empty.
And hangovers? Oh boy. Alcohol is a diuretic—it drains you. Plus, it irritates your stomach lining directly. Double trouble. You’re dehydrated and inflamed. Vomiting is practically guaranteed.
So next time you’re hungover and hugging the toilet, remember: it’s not the tequila’s fault. It’s your body’s desperate, misguided attempt to save you. “I’ll protect you by making you miserable!” Classic.
