Sleep quality plays a crucial role in human health, but its determinants remain incompletelyunderstood. This integrated analysis investigates the relationships of demographic characteristics, living habits, as well as psychological factors on sleep quality. It also ranks the importance of sleep discomfort and examines the effect of bedroom air quality on sleep quality. Results showed stress had a significant negative correlation (r = -0.66) with sleep quality. Furthermore, nocturnal bathroom usage was the most influential predictor, contributing approximately 17.5% to sleep quality ratings using random forest classification. Air quality measures, including carbon dioxide (CO2) levels, temperature, relative humidity, and particulate matter (PM2.5), demonstrated no significant impact on sleep quality. This research builds a stepstone for more precise sleep intervention by looking at the interaction of impacting factors and creates methods to generate new features from real-time air quality sensor data.
