How Wearable Tech Is Measuring Biological Age

Smartwatches and fitness trackers now claim to estimate your biological age — the age of your body at the cellular level, which can differ from your chronological age. In this episode, Lucas and Luna explore how these devices use heart rate variability, sleep patterns, and activity data to compute a number that might be younger — or older — than your years. They dig into the science behind the algorithms, look at a 2025 Stanford study that compared wearable-based biological age estimates to clinical biomarkers, and talk about the growing trend of people using these metrics to guide lifestyle changes. They also discuss the limitations and ethical questions, like whether insurance companies might start using this data. If you've ever wondered what your watch means when it tells you your 'fitness age' or 'body age,' this episode breaks it down. #BiologicalAge #WearableTech #Smartwatch #FitnessTracker #HealthTech #HeartRateVariability #SleepTracking #Longevity #Technology #Health #Science #Stanford #Biomarkers #FexingoBusiness #BusinessPodcast #Podcast #Aging #PreventiveHealth Keep every episode free: buymeacoffee.com/fexingo
