How Wearables Are Tracking Your Blood Oxygen

Smartwatches have been measuring blood oxygen saturation for years, but what does that number actually mean? In this episode, Lucas and Luna unpack the science behind pulse oximetry, the limitations of consumer sensors, and the emerging medical research that is turning SpO2 into a serious health metric. They look at how overnight tracking is catching undiagnosed breathing issues, how altitude training enthusiasts use the data, and why the number on your wrist can be misleading for people with darker skin tones. The hosts also discuss the regulatory landscape and what the next generation of sensors might bring. If you have ever wondered whether your watch's oxygen reading is trustworthy, this episode gives you the context you need. #BloodOxygen #SpO2 #PulseOximetry #WearableTech #SmartwatchFeatures #HealthTracking #FitnessTracking #MedicalResearch #SleepApnea #AltitudeTraining #SkinToneBias #SensorAccuracy #ConsumerHealth #TechRegulation #WearableSensors #HealthMetrics #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
