Should AI Health Assistants Tell You When a Wearable Wasn’t Worn?

A missing night is not a bad night. Samsung’s Health Assistant can combine sleep, activity, nutrition, mindfulness and vital-sign data. Its Energy Score needs the previous day’s activity, sleep and sleeping heart-rate data from a compatible watch or ring. But bodies and sensors part ways: a loose band, a ring left charging, a watch on the nightstand. If the assistant smooths over that gap, physical absence becomes a fake health story. Every recommendation should say which device was worn, for how long and where the record is thin. When there isn’t enough data, “I don’t know” is better than scoring someone’s morning. Would that honesty make an AI health assistant more useful, or just add clutter?
