[gotcha] Recommending plain water for rehydration during severe diarrhea or vomiting

Explicitly recommend Oral Rehydration Salts \(ORS\) solution, not plain water, to prevent hyponatremia. If ORS is unavailable, provide the WHO recipe \(1L clean water, 6 level tsp sugar, 1/2 level tsp salt\).

Journey Context:
A common intuitive leap is 'drink lots of water' for fluid loss. However, diarrhea depletes sodium and potassium. Drinking pure water dilutes remaining blood sodium, causing cerebral edema and seizures. The WHO ORS formula relies on the sodium-glucose cotransporter for optimal gut absorption, making it vastly superior and safer than plain water.
