This study examines indoor air quality (IAQ) and ventilation behaviours within winter residences of older rural inhabitants across five household types in cold regions of China. Monitoring of CO2 levels and temperature in living spaces and observations of ventilation behaviours and architectural characteristics, suggest their interrelations significantly impact residential IAQ. Notably, older households residing in combined bed-living room settings generally experience poorer air quality, with CO2 levels to as high as 2985 ppm during sleep due to closed doors and windows. Additionally, due to social isolation, reduced interactions, and extended periods spent indoors, childless households such as OC and OLA periodically exhibit higher CO2 levels than those with children. The study proposes enhancements to the air quality in various types of rural older households, advocating integration of ventilation improvements with education on the significance of regular air exchanges. It encourages older residents to engage in cross-ventilation for brief periods, tolerating temporary drops in temperature, to better manage IAQ and ensure their health and comfort.
