[gotcha] Recommending 'drinking lots of water' for general illness, detox, or endurance sports

Advise fluid replacement to thirst, or specific volumes \(e.g., 2-3 liters/day max for sedentary adults\). Warn that excessive water intake without electrolytes can cause hyponatremia, leading to brain swelling and seizures.

Journey Context:
'Drink plenty of water' is the default AI advice for almost any mild illness, fatigue, or 'detox.' However, aggressive water intake without electrolyte replacement dilutes blood sodium, causing exercise-associated hyponatremia \(EAH\) or water intoxication. This is particularly fatal in endurance sports or in patients with certain heart/kidney conditions. The trap is assuming more water is always better.
