Why is it dangerous to give a baby under 6 months old plain water or watered-down formula?¶

Babies under 6 months of age have immature kidneys that cannot filter out extra plain water quickly, and their tiny bodies hold very little total sodium. Giving an infant even a few ounces of plain water, or adding extra water to stretch powdered baby formula, rapidly dilutes the sodium in the baby's bloodstream. Within hours, water moves into the baby's brain cells, causing a drop in body temperature (below 36.1 degrees Celsius / 97 degrees Fahrenheit), facial puffiness, lethargy, vomiting, and life-threatening hyponatremic seizures. Infants under 6 months should receive only breast milk or properly mixed standard infant formula.

Why does MDMA ("Ecstasy" or "Molly") cause fatal water intoxication after drinking only a few bottles of water?¶

Normally, if you drink an extra liter or two of water, your brain stops releasing Antidiuretic Hormone (ADH) and your kidneys urinate out the extra water within an hour. MDMA chemically stimulates the hypothalamus to release a massive, continuous surge of ADH that locks the kidneys shut for 12 to 24 hours so they cannot urinate out free water. At the same time, MDMA raises body temperature and causes intense thirst. When a user drinks several bottles of water to cool down, 100 percent of that water stays trapped in their bloodstream, causing rapid brain swelling, seizures, and brainstem herniation.

What is the difference between treating acute water intoxication (< 24 hours) and chronic low sodium (> 48 hours)?¶

In acute water intoxication (where blood sodium drops over a few hours during a marathon, rave, or water-drinking contest), brain cells have not had time to adapt, so the immediate threat is fatal brain swelling and herniation. Doctors give rapid intravenous boluses of 100 mL of 3% Hypertonic Saline to quickly raise blood sodium by 4 to 6 mEq/L and shrink the brain back down, with virtually zero risk of demyelination. In contrast, when someone develops chronic low sodium slowly over many days or weeks (from water pills, heart failure, or liver disease), their brain cells have already adapted; while doctors still give an initial 4 to 6 mEq/L hypertonic bolus if the patient is seizing, they must strictly cap the total sodium rise at no more than 6 to 8 mEq/L per 24 hours to prevent Osmotic Demyelination Syndrome (ODS).
