People using drugs such as MDMA (often referred to colloquially as "Ecstasy") may overexert themselves, perspire heavily, feel increased thirst, and then drink large amounts of water to rehydrate, leading to electrolyte imbalance and water intoxication – this is compounded by MDMA use increasing the levels of antidiuretic hormone (ADH), decreasing the amount of water lost through urination. Even people who are resting quietly in extreme heat or humidity may run the risk of water intoxication if they drink large amounts of water over short periods for rehydration. Psychiatric conditions
Psychogenic polydipsia is the psychiatric condition in which patients feel compelled to drink large quantities of water, thus putting them at risk of water intoxication. This condition can be especially dangerous if the patient also exhibits other psychiatric indications (as is often the case), as the care-takers might misinterpret the hyponatremic symptoms. Iatrogenic
When an unconscious person is being fed intravenously (for example, total parenteral nutrition) or via a nasogastric tube, the fluids given must be carefully balanced in composition to match fluids and electrolytes lost. These fluids are typically hypertonic, and so water is often co-administered. If the electrolytes are not monitored (even in an ambulatory patient), either hypernatremia or hyponatremia may result.Some neurological/psychiatric medications (oxcarbazepine, among others) have been found to cause hyponatremia in some patients. Patients with diabetes insipidus are particularly vulnerable due to rapid fluid processing.
January 12, 2007: Jennifer Strange died after drinking nearly 2 gallons (7.6 liters) of water in an attempt to win a Nintendo Wii. The KDND radio stations morning show, the Morning Rave, held an on-air contest entitled "Hold Your Wee for a Wii," in which contestants were asked to drink as much water as they could without urinating. The DJs were made aware of the dangers but did not inform the contestants. KDNDs parent company, Entercom Sacramento LLC, was subsequently ordered to pay $16,577,118 in damages to Stranges family. March 11, 2020: Zachary Sabin, an 11-year-old child, died after being forced to drink almost three liters of water in just four hours by his parents. They thought his urine was too dark, so they made him drink water until he threw up. See also
