Study Details
Nature and Science of Sleep
View Summary
This in-home intervention study examined the effects of sleeping at a 12° incline using an adjustable bed base compared to flat sleeping in adults who snore.
Key findings:
- 7% reduction in snoring
- 4% decrease in nighttime awakenings
- 5% increase in deep sleep
- Improved subjective restfulness ratings
The study suggests inclined sleeping has potential as a non-obtrusive means of reducing snoring and improving sleep quality.
Sleep and Breathing
View Summary
This study examined how head-of-bed elevation affects obstructive sleep apnea severity in patients with mild to moderate OSA.
Key findings:
- 7.5° incline reduced OSA severity by 31.8% average
- Improved oxygen saturation during sleep
- Reduced apnea-hypopnea index
- May be useful adjunct to other OSA treatments
The researchers note positional therapy (including bed elevation) is an underutilized approach for mild-moderate OSA.
Journal of Gastroenterology and Hepatology
View Summary
This study examined the effect of bed head elevation on nocturnal gastroesophageal reflux and sleep quality.
Patients sleeping with elevated bed heads showed significant reductions in acid reflux episodes, faster acid clearance, and improved subjective sleep quality.
Evidence Assessment
This intervention has preliminary evidence from early-stage research, mechanistic studies, or observational data. More rigorous trials are needed.
