Consistent Sleep Patterns Reduce Mortality Risk More Than Total Sleep Hours
While adults typically need 7-9 hours of sleep per night, consistency in your sleep schedule matters more for reducing mortality risk than the total hours slept.
- Measures consistency of sleep timing; higher scores indicate regular patterns linked to lower mortality.
- Irregular sleep raises death risk by 19-48%, surpassing the impact of sleep duration.
