A new Slate feature warns that overdrinking can cause life-threatening low sodium levels.
The piece links heavy hydration habits to exercise-associated hyponatremia and urgent medical risks (Slate).

This report explains the new findings and the risks for people in Thailand.
It shows what athletes, outdoor workers, families, and public-health planners should do now.

Hyponatremia means low sodium in the blood.
Doctors define normal sodium as 135 to 145 mmol per liter (Slate).

A recent personal report links a healthy lifestyle to a near-loss of consciousness and seizure risk from low blood sodium. The account appears in Slate and warns that excess water can harm the brain (Slate).

Hyponatremia means low sodium in the bloodstream. Low sodium can cause brain swelling. Severe cases can cause confusion, seizures, coma, and death (Mayo Clinic).

Doctors note two common hydration errors. One error is not drinking enough fluid. The other error is drinking too much plain water. The Slate report describes a case of the latter (Slate).
