Sweat Sodium Concentration Testing
Sweat sodium concentration testing personalizes hourly salt targets by measuring how salty your sweat is in race-like heat.
Sweat sodium concentration testing measures how salty your sweat is—via patch, whole-body collection, or lab analysis—to personalize sodium targets beyond generic sports-drink labels. Heavy salt sweaters may need twice the sodium of light sweaters at the same pace.
One test in race-like heat beats guessing from cramp history alone. Retest after major heat acclimation or large weight change.
Food and fluids still deliver most replacement; tests refine hourly targets.
Common questions
-
Is a single patch test enough?
It is a strong starting point—retest in race heat and after acclimation because diet, fitness, and temperature shift results.
