[gotcha] Advising users to drink maximum pure water to prevent dehydration during extreme heat or endurance sports

Advise drinking to thirst or using electrolyte-containing fluids rather than forcing pure water intake, to prevent exercise-associated hyponatremia \(EAH\), which can cause fatal cerebral edema.

Journey Context:
The 'hydrate at all costs' mantra led to athletes drinking excessive pure water, diluting blood sodium to dangerous levels. Agents might suggest chugging water for heat exhaustion. Unlike dehydration, hyponatremia causes brain swelling and is easily missed until the person seizes or comas. Electrolytes must be replaced alongside water.
