Abstract

Abstract: Introduction: We explored how bed comfort was related to self-report sleep patterns and perception of sleep. Methods: 3, 007 adults (2, 793 females) between the ages of 18 to 86, recruited through social media, completed a comprehensive online sleep assessment modified for mobile experience, including the Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), Sleep Hygiene Index, and questions about attempted sleep solutions. Results: 20.4% of subjects reported sleeping on an uncomfortable bed either "always" or "frequently." The perception of bed comfort was positively correlated with both age and income. 28% of subjects with household income less than $30, 000 reported an uncomfortable bed compared with only 8.0% of subjects with incomes over $130, 000. Participants who reported sleeping on an uncomfortable bed had significantly higher ISI scores (15.1 vs 16.9), p<0.001. Self-reported sleep onset latency (SOL) was associated with bed discomfort, with an average 20 minutes longer SOL for those that "always" sleep on an uncomfortable bed compared to "never." Bed comfort was not associated with number or duration of night wakings. Nightmare frequency was also significantly higher for those that slept on an uncomfortable bed (1.62 nightmares/wk vs 0.91/wk, p<0.001). Bed discomfort was associated with daytime sleepiness with higher ESS scores (8.3 vs 9.5), p<0.001. Furthermore, reported bed comfort was significantly correlated with alertness at work (p<0.001). Conclusion: While bed discomfort is clearly associated with increased likelihood of insomnia, nightmares, and daytime sleepiness, we cannot know explicitly the direction of the causality. This is an important question that needs more exploration. Should individuals who report poor sleep and an uncomfortable bed begin by changing behaviors or changing their bed⋯ or both?
