Google Research introduces investigational wearable health-age and coaching framework
Overview
Google Research introduces an investigational framework that turns wearable data such as resting heart rate, steps, sleep and Active Zone Minutes into a coachable health age metric.
Its SensorWM world model simulates 12-week what-if habit trajectories, and a language model turns them into coaching plans. In a blinded study, lifestyle coaches preferred the counterfactual-grounded plans in 71.4% of evaluations. A companion study extends the framework to routine blood biomarkers for early cardiovascular-kidney-metabolic health tracking.
Google says the evaluations were offline, using retrospective research cohorts, and that the models are research prototypes rather than clinical diagnostic tools. The work lays groundwork for future prospective trials of interactive what-if coaching.

Google Research@GoogleResearchOfficialGoogle Research introduces an investigational health-age ML frameworkAIGoogle Research introduces an investigational ML framework that translates passive wearable signals into a modifiable, coachable health age. The framework uses an action-conditioned world model to simulate personalized 12-week "what-if" habit trajectories. It also expands to routine blood biomarkers to track early cardiovascular-kidney-metabolic (CKM) health.

AIGoogle Research introduces an investigational framework that builds a coachable health age metric from wearable data such as resting heart rate, steps, sleep, and Active Zone Minutes. Its SensorWM world model simulates 12-week what-if habit trajectories, which a language model turns into coaching plans. In a blinded study, lifestyle coaches preferred the counterfactual-grounded plans in 71.4% of evaluations, and the authors note the models are research prototypes, not clinical diagnostic tools.
