Smartwatch AI now predicts your real 'health age' and shows how changing habits alters your future

Researchers have developed a new AI framework that uses data from wearable devices like smartwatches to estimate a person's 'cardiovascular-kidney-metabolic (CKM) health age'—a measure of physiological aging that goes beyond simple chronological age. Unlike traditional 'biological clocks,' this system is designed to be 'coachable,' showing users how specific daily habit changes (like adding more sleep or exercise) could potentially improve their long-term health trajectory.

The approach aims to move health tracking from passive monitoring to actionable guidance, providing personalized simulations of how lifestyle modifications might impact future CKM risk. This represents a meaningful technical step toward translating everyday wearable data into personalized, preventive health coaching that could help users reverse early signs of interconnected metabolic, heart, and kidney conditions before symptoms appear.
