Abstract:Previous research indicates that there is a relationship between sleep and well-being. Yet, it remains unclear what constitutes this relationship. It was hypothesised that good sleep quality and good composite sleep are each associated with increased subjective well-being including increased satisfaction with life and increased positive and decreased negative affect, whereas sleep duration is not. Subjective well-being was measured using the Satisfaction with Life Scale (SWLS) and the Scale of Positive and Negative Experience (SPANE). Sleep was measured using the National Sleep Foundation’s Sleep Health Index (SHI). A correlational design with multivariate multiple linear regression analysis was applied. A statistically significant association between good sleep quality and increased subjective well-being was found. No evidence was found for a relationship between sleep duration and subjective well-being. Good composite sleep was significantly associated with increased subjective well-being, although the explanatory power was much smaller (15% explained variance) than that of sleep quality alone (26% or 27% explained variance). There is indeed a relationship between sleep and well-being and sleep quality alone is the single best predictor in subjective well-being. Practically, the sleep industry should focus on promoting sleep quality instead of sleep duration when aiming at improving their customers’ well-being.
