Using Nix Biosensors in our advanced sweat test, we measure how much sodium you lose through sweat. Between seemingly similar individuals, sodium loss can vary up to 15 times, and will remain constant. As part of the test, a Biosensor is placed on your arm, analyzing the sweat glands on your arm. To determine how much sodium is lost through sweat, we capture it and run it through our analyser. With the data collected during the test, we create a detailed hydration strategy you can follow to stay well-hydrated in training and competition, minimise cramp risk, and boost performance. It's a active sweat test, you will need to run or cycle. Please bring your workout gear and towel. Nix Hydration Biosensor No more trial and error to identify your optimal hydration strategy.
