Claims supported
- Objective sleep regularity is associated with all-cause and cause-specific mortality risk, and may capture a health-relevant sleep dimension that average duration alone misses.
- Sleep duration, sleep quality, and sleep regularity are distinct dimensions of sleep health, and consumer claims should avoid treating hours slept as the whole sleep signal.
- Improving sleep duration, quality, or regularity is a plausible health intervention, but direct evidence that consumer sleep improvement lowers all-cause mortality remains under-proven.
