Micronutrients & recovery
Regional sweat rate and sodium concentration measured via wearable microfluidic patches can be used to predict whole-body fluid and electrolyte loss during exercise with high accuracy for individuals.
To optimize hydration, you cannot rely on a 'one size fits all' sweat rate. Use a wearable sweat sensor to measure your specific sweat sodium and rate at key locations (like the forehead or forearm). Use this personal data to predict your total fluid and electrolyte loss during exercise, allowing you to replace exactly what you lose rather than guessing.
These experimental results indicate that local sweat parameters can be continuously monitored in situ to notify individuals of their hydration status and electrolyte balance.
Why this rating
Small sample size (n=3 subjects) limits generalizability, though the correlation within subjects was strong.
