Overview
- Fewer than 13% of people consistently met common benchmarks of 7–9 hours of sleep and roughly 8,000 daily steps.
- Sleep quality and duration predicted higher step counts the following day more strongly than daily steps predicted that night’s rest.
- About 17% averaged under seven hours of sleep and fewer than 5,000 steps, a combination linked in prior research to higher risks of chronic disease and mental-health problems.
- The dataset covered over 70,000 participants across roughly 3.5 years, totaling more than 28 million person-days from consumer health devices.
- Study authors recommend prioritizing better rest—such as consistent bedtimes and reduced pre-sleep screen time—to help increase daily physical activity.
