Abstract

People spend approximately one-third of their lifetime sleeping, yet nearly no standards define indoor environmental quality conditions for optimal sleep. We summarized studies examining the effects of bedroom ventilation on sleep quality. The results suggest that current ventilation standards for dwellings are inadequate concerning requirements of outdoor air supply rates in bedrooms and need to be revised. We propose that the bedroom ventilation rate should be around 10 L/s per person to avoid disturbance to sleep. This ventilation rate corresponds to a carbon dioxide concentration of about 400 ppm above the outdoor level in the bedroom and an air change rate of around 1 h-1 for a typical bedroom. These rates can frequently be achieved by intelligent air distribution within the dwelling.
