Your Smartwatch May Predict Disease Risk by Tracking Your Body Clock

Key Insight

This study suggests keeping a steady daily rhythm of activity may track with better long-term health.


Your body has a daily rhythm for movement and temperature, and how well these two line up seems to matter. In about 90,000 middle-aged and older adults, those with better-synced daily rhythms had lower odds of diabetes, heart disease, depression, and early death. This data came from a week of wrist-worn trackers, the same kind many people already use.
