- Abnormal sleep duration and poor sleep quality are linked to increased risks of cardiovascular disease (CVD) incidence and mortality.
- The study included 483,384 adults from the China Kadoorie Biobank (CKB) who were free of major diseases at baseline.
- Sleep duration was categorized into <6 h/d, 6-9 h/d, and >9 h/d, with sleep disturbance symptoms including difficulties initiating/maintaining sleep, early morning awakening, and daytime dysfunction.
- Longer sleep duration (>9 h/d) had the greatest impact on reducing total life expectancy (LE) and LE free of CVD, with men experiencing a greater reduction than women.
- Sleep disturbance had a stronger impact on reducing disease-free LE than total LE, leading to a lower proportion of life spent in a healthy state.
- The study highlights the importance of good sleep habits for overall health and longevity, especially in the context of CVD prevention.
