How Your Smartwatch Tracks UV Exposure for Skin Health

This summer, UV indexes have hit extreme levels. Lucas explores how modern smartwatches are now measuring UV exposure in real time, helping you avoid sun damage and even detect risk of skin cancer. He breaks down the sensor technology — photodiodes on the wrist — and cites a new study from UCSF showing that wearables can accurately track cumulative UV dose. Luna asks about differences between brands and whether this replaces a dermatologist's advice. The episode ends with a look at how UV data might integrate with health insurance wellness programs. #WearableTech #UVExposure #SkinHealth #Smartwatch #SunProtection #HealthTech #Technology #Podcast #FexingoBusiness #BusinessPodcast #Wearables #UCSF #AppleWatch #Garmin #Photodiode #PreventiveHealth #Summer2026 #ClinicalStudy Keep every episode free: buymeacoffee.com/fexingo
