“…In this study, by combing the indoor environment elements contained in the buildings of senior housing and nursing homes with the supplement of semi-structured interviews, we established an index system of elderly people's bedroom living environment preference by dividing the bedroom elements into five parts: basic bedroom conditions, bedroom materials, bedroom colors, bedroom physical environment and other soft furnishings [28][29][30][31][32][33][34][35][36][37] (see Table 1). According to this index system, a questionnaire was designed.…”

This study aims to analyze the indoor environment preferences of Chinese urban elderly, to create a living environment that is beneficial to the physical and mental health of Chinese elderly, and to enhance their sense of well-being. Based on an in-depth study of 306 urban elderly’s bedroom indoor environment preference in 21 Chinese provinces, using questionnaire method, this study concludes that: (1) Group characteristics: for urban elderly, the key words for bedroom color and lighting preference are low saturation, bright, warm tones and warm white light; personal characteristics such as the gender, physical condition, and education have a strong correlation with factors in the indoor living environment; (2) Physical environment preferences: gender presents the most significant potential effect on elderly physical environment preferences; (3) Established indicator system: the indicator system includes five main indicators of basic bedroom conditions, bedroom materials, bedroom colors, bedroom physical environment and other soft furnishings, and 22 sub-indicators. This study has some implications for guiding the design of elderly’s apartments and the bedroom environment, as well as effectively using the indoor environment to meet the physiological and psychological needs of the urban elderly.

“…Thermal comfort throughout the night also positively correlates with perceived sleep quality [17][18][19]. Previous studies have manipulated ambient temperature based on sleep stages to enhance thermal comfort and perceived sleep quality [17][18][19][20]. However, maintaining an optimal skin temperature range during sleep can be difficult if hot or cold ambient bedroom temperatures cannot be offset by clothing, bedding, and/or HVAC systems [11,13,21].…”

Body temperature should be tightly regulated for optimal sleep. However, various extrinsic and intrinsic factors can alter body temperature during sleep. In a free-living study, we examined how sleep and cardiovascular health metrics were affected by sleeping for one week with (Pod ON) vs. without (Pod OFF), an active temperature-controlled mattress cover (the Eight Sleep Pod). A total of 54 subjects wore a home sleep test device (HST) for eight nights: four nights each with Pod ON and OFF (>300 total HST nights). Nightly sleeping heart rate (HR) and heart rate variability (HRV) were collected. Compared to Pod OFF, men and women sleeping at cooler temperatures in the first half of the night significantly improved deep (+14 min; +22% mean change; p = 0.003) and REM (+9 min; +25% mean change; p = 0.033) sleep, respectively. Men sleeping at warm temperatures in the second half of the night significantly improved light sleep (+23 min; +19% mean change; p = 0.023). Overall, sleeping HR (−2% mean change) and HRV (+7% mean change) significantly improved with Pod ON (p < 0.01). To our knowledge, this is the first study to show a continuously temperature-regulated bed surface can (1) significantly modify time spent in specific sleep stages in certain parts of the night, and (2) enhance cardiovascular recovery during sleep.

With the Pod on, men’s deep and light sleep increased by 14 and 23 min, respectively, while women’s REM sleep increased by 9 min. Sleeping HR (-2%) and HRV (+ 7%) significantly improved with Pod on. To our knowledge, this is the first study to show that a continuously temperature-regulated bed surface can significantly 1) modify time spent in sleep stages at specific points in the night, 2) improve thermal comfort and perceived sleep quality, and 3) enhance cardiovascular recovery (HR and HRV) during sleep.
