Higher percentages of REM and deep sleep are associated with a reduced incidence of atrial fibrillation, while higher light sleep percentages are associated with increased odds of atrial fibrillation.
Prioritize sleep quality that promotes REM and deep sleep. While total duration is important, the composition of your sleep matters for heart health. Consistent sleep schedules and avoiding alcohol before bed may help increase deep and REM sleep, thereby reducing atrial fibrillation risk.
When examining Fitbit-derived sleep stages, each percent increase in REM sleep was associated with a reduced incidence of heart rhythm and rate abnormalities, including atrial fibrillation (OR 0.86; 95% CI 0.82–0.91)... Higher deep sleep percentage (per percent) was also associated with lower odds of atrial fibrillation (0.87; 0.81–0.93)... Higher light sleep percentage (per percent) was associated with increased odds of atrial fibrillation (1.13; 1.09–1.17)...

- Increased sleep irregularity (defined as higher standard deviation of daily sleep duration) is associated with increased odds of incident obesity, essential hypertension, hyperlipidemia, major depressive disorder, and generalized anxiety disorder.Good
- Average daily sleep duration exhibits a J-shaped association with hypertension, major depressive disorder, and generalized anxiety disorder, where both short (5h) and long (10h) durations increase risk compared to the median (6.8h).Good
