Technology Highlights

• The invention provides a method to know one's individual rates of cutaneous water loss for given circumstances and tailor drinking behaviors to avoid over-drinking and under-drinking thus optimizing health and performance.
• The invention accurately predicts individual exercise fluid needs (i.e., sweat losses).
• The invention provides athletes, coaches, researchers, and industry with a simple and accurate means of estimating exercise sweat losses to better manage athlete hydration.
• The invention predicts sweat losses before, during, and after exercise.
• The invention can be used to forecast sweat losses in different venues, thus adding product value and end-user appeal to sports wearables, fitness apps, sweat patches, and smart bottles.
• The invention is easily integrated directly into existing sports wearables and fitness app platforms or using a variety of DevOps (e.g., API, SDK).
• The invention allows accurate (> 90% accuracy) estimates of whole body sweat electrolyte losses from the product of local patch sweat [electrolyte] measurements and accurate whole body sweat loss predictions.
• The invention sweat loss predictions are the perfect complement to sports beverage and fluid delivery businesses aiming to optimize and personalize athlete hydration.
• The invention provides the missing link for on-demand, bespoke hydration when combined with novel fluid intake tracking and personal sweat electrolyte profiles.
• The invention is easily incorporated into existing sports wearables or fitness app platforms.
• The invention is a natural complement to sweat patch and smart fluid delivery technologies.
• The invention improves performance (reduce dehydration) and sustain health (reduce hyponatremia risk).
