How Wearables Are Measuring Your Hydration Strategy

We look at why step counts and heart rate are no longer enough to gauge physical stress, turning our attention to the emerging frontier of continuous hydration monitoring. With major players like Garmin and Apple integrating sweat loss algorithms into their fitness trackers, we explore how devices use skin temperature, galvanic skin response, and activity intensity to estimate fluid loss in real time. We break down the science behind these estimates, the limitations of current optical sensors, and what this means for endurance athletes and office workers alike. The episode examines a recent study on sweat electrolyte variation and discusses whether your smartwatch can truly tell you when to drink water before you feel thirsty. #WearableTech #HydrationTracking #HealthTech #FitnessData #Smartwatches #Garmin #AppleWatch #SweatLoss #Electrolytes #EnduranceTraining #BiometricSensors #SkinTemperature #GalvanicResponse #FitnessAnalytics #WellnessTrends #FexingoBusiness #BusinessPodcast #TechInnovation Keep every episode free: buymeacoffee.com/fexingo
