Water Intoxication and the Duluth Seizure Cluster

At 1:22:25 · chapter starts 1:14:10

For years Monica has warned about the dangers of drinking too much water, a position that earns gentle mockery. Then she brings a real case: a friend of a friend who drank excessive water during an exercise routine, developed critically low sodium levels, and had a seizure. The medical term, confirmed by an AI search, is hyponatremia — cells literally swell with water, threatening brain function. This prompts an unexpected revelation: their mutual friend Robbie, it turns out, has four people in his immediate social circle who have experienced seizures — Monica, his wife, his sister, and another Indian friend — all from a suspiciously small geographic area near Duluth. A live phone call with Robbie confirms the fourth case. Dax and Monica propose a true-crime-style podcast called 'Poison Paradise' to investigate the shared water source, with Robbie as the velvet-voiced lead correspondent.
