Abstract

The present study investigated the effects of bedroom ventilation on sleep quality. Objective and subjective sleep quality was measured by sleep trackers and the Groningen Sleep Quality Scale (GSQS), respectively. CO₂, NO₂, VOCs, PM₁₀ and PM_2.5 levels were measured in 38 bedrooms. Air pollutants were not significantly correlated with any of the sleep parameters in the present study. The subjects rated better sleep quality while sleeping with either window or door open, compared to those sleeping with both window and door closed. However, CO₂ levels seemed to be associated with REM sleep in a different way. Further analyses and studies are needed to confirm these results.
