How Wearable Sensors Detect Dehydration Before You Feel Thirsty

In this episode, Lucas and Luna explore how wearable sweat sensors and skin conductance patches can detect dehydration before you even feel thirsty. They dive into the science behind perspiration analysis, the role of biomarkers like sodium and chloride, and how companies like Gatorade's Gx Sweat Patch and newer FDA-cleared devices are changing sports hydration. Lucas explains the key metric — sweat sodium concentration — and how it correlates with fluid loss. Luna raises the question of accuracy and individual variability, and they discuss whether this tech is moving beyond elite athletes to everyday consumers. They also cover the challenges of calibration, sweat rate vs. sweat composition, and the future of continuous hydration monitoring. A concrete look at one of the fastest-growing niches in wearable health sensors. #WearableTech #HydrationSensors #SweatSensors #Dehydration #Biomarkers #Sodium #Chloride #Gatorade #GxSweatPatch #FDA #AthleticPerformance #ContinuousMonitoring #SkinConductance #HealthTech #FitnessTrackers #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
