[gotcha] Recommending Pure Water for Severe Dehydration or Endurance Sports

Recommend Oral Rehydration Solutions \(ORS\) with electrolytes rather than pure water for severe diarrhea/vomiting or heavy prolonged sweating. Warn against chugging pure water if experiencing confusion or nausea.

Journey Context:
'Drink water' is the default agent response for dehydration. However, excessive pure water intake without electrolytes leads to exercise-associated hyponatremia \(EAH\) or dilutional hyponatremia, which can cause cerebral edema and death. ORS is the WHO standard for fluid loss because it relies on sodium-glucose cotransport.
