Why Your Wearable Ignores Your Stress Hormones

We examine the gap between optical heart rate sensors and actual cortisol levels in wearable health tech. Lucas and Luna discuss why companies like Whoop and Oura avoid measuring stress hormones directly, focusing instead on heart rate variability as a proxy. We explore the science behind cortisol spikes, the limitations of indirect measurement, and what this means for your daily recovery strategy. The episode anchors on recent clinical studies comparing wearable data against saliva tests, revealing where these devices succeed and where they fundamentally fail to capture the body's chemical reality. #WearableTech #HealthMonitoring #CortisolLevels #HeartRateVariability #StressManagement #Biofeedback #WhoopBand #OuraRing #AppleWatch #Fitbit #HRVData #AutonomicNervousSystem #SleepRecovery #MentalHealthTech #FitnessTracking #PhysiologicalStress #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
