Smart Rings, Smartwatches, Continuous Glucose Monitors, AI Health Scores, and What Your Body Data Really Means
Published by POPR Books
Your smartwatch collects thousands of data points every day. But what do they actually mean? Modern health wearables can measure heart rhythms, estimate sleep quality, detect irregular patterns, and calculate recovery scores — yet many people confuse wellness features with medical devices, AI scores with diagnoses, and marketing claims with scientific evidence. The 2026 Health Wearables Guide explains what today's wearable technology actually measures, how artificial intelligence interprets that information, where FDA authorization begins and ends, and why those distinctions matter more than ever. Covers smart rings versus smartwatches, how continuous glucose monitors are expanding beyond diabetes care, why no smartwatch currently has FDA authorization to independently measure blood glucose without piercing the skin, how wearable health scores are calculated, and how to build a useful long-term personal health baseline. Written in plain language and grounded in verified research. Verified through July 2026.
