Hyponatremia

Consuming sodium temporarily resolves hyponatremia, relieving headaches and producing a noticeable sense of calm or relaxation. Hyponatremia is distinct from classic dehydration: it is not caused by too little water but by too much water without enough sodium. The body requires a minimum of 3.5 to 5 grams of sodium per day, equivalent to 1.5 to 2 teaspoons of sea salt. Drinking water to thirst rather than arbitrary volume targets is the recommended approach. Kidney stone formers need at least 2.5 liters of fluid per day to prevent stone formation. Research on over-hydrated long-distance runners documents low sodium levels and deaths in high-profile racing events. Rapid improvement in weakness after consuming sea salt is a strong indicator that sodium deficiency was the cause. Diuretic medications deplete sodium and chloride levels. The combination of diuretics, high water intake, exercise, and sweating creates compounding risk for hyponatremia. Diuretics and certain antidepressants promote sodium excretion through the kidneys. Sodium dilution causes brain cells to swell due to osmotic imbalance. When blood sodium drops too low, the brain and nervous system lose the ionic environme…
