Without enough sodium, water starts sneaking into your cells, including your brain cells. And brain cells don’t like to stretch—they’re not yoga enthusiasts. As they swell, your skull (which is a fixed box, by the way) starts squeezing them, causing symptoms you’d probably dismiss as “just a bad day.”
First comes the headache, then nausea, confusion, and that “I’m about to pass out” feeling—exactly what Dave experienced. If left unchecked, you can hit seizures, coma, or even death. Yes, death by water. It’s like nature’s cruel joke: the thing that sustains you can also drown you from the inside.
So how much is too much?
There’s no magic number that fits everyone, which is annoying, I know. But a good rule of thumb? If your pee is clear as tap water and you’re peeing every 15 minutes, you’re overdoing it. Healthy urine should look like pale lemonade—not a swimming pool. And if you start feeling sloshy or nauseous during a water challenge, stop and eat something salty (potato chips are actually a medical intervention here, and I’m not joking).
Water Intoxication Symptoms
Most people who get into trouble are endurance athletes, party-goers on ecstasy (which makes you thirsty), or well-meaning health nuts like Dave. They think, “More water = more health,” but your body isn’t an unlimited sponge. It’s a precision instrument, and it hates extremes.
