“…The present study shows that increasing the ventilation in the room reduced the CO 2 and PM 2.5 concentrations (Table 3) and improved the sleep quality of the elderly subjects, as indicated by an increased duration of deep sleep and REM sleep (Table 4). Similarly positive effects of bedroom ventilation on sleep quality in both elderly and young adults have been reported in recent studies 24,25,50 . However, Fan et al found no change in sleep stages for young subjects at a higher CO 2 concentration of 1700 ppm 50 .…”

However, Fan et al found no change in sleep stages for young subjects at a higher CO 2 concentration of 1700 ppm 50 . This suggest that the sleep quality of elderly subjects might be more susceptible to the negative effects of indoor pollutants than that of young subjects.…”

Aging populations are a world-wide concern. The Chinese demographic statistics announced in March 2021 showed that the percentage of the population 60 years old or more in China was 18.7% (260 million). People experience many physiological and psychological changes in old age, including a decrease in sleep quality and quantity and altered sleep structure. 1 Sleep disturbance of about 50% has been observed among the elderly in many countries. [2][3][4][5][6][7] Sleep disturbance is detrimental to both the physical and mental

“…Two separate studies conducted in different locations (residential homes and climbing rooms) have yielded similar results, showing that when windows or doors are opened, air quality improves, in terms of CO2 concentration. Optimal IAQ indicators have a positive impact on sleep duration and subjective sleep quality Fan, Shao, et al, 2022). The results of this improved sleep have a beneficial effect on cognitive performance the following day [16].…”

This study aims to investigate the impact of carbon dioxide (CO2) levels on sleep efficiency in university dormitories. The quality of the indoor environment, including CO2 concentrations, can significantly influence the health and comfort of dormitory occupants. Poor sleep efficiency can lead to long-term cognitive disturbances and health problems. Therefore, understanding the relationship between CO2 levels and sleep efficiency in the university dormitory environment is crucial to improving the living conditions of students. The study was carried out through field surveys at Diponegoro University Dormitory. The real-time CO2 data in the rooms was measured using a logger monitoring device. In addition, the sleep efficiency of the students was evaluated using sleep tracking devices and sleep journals filled out by the participants. Other data, such as ventilation rates and room temperature, were also collected as determinants of environmental quality. The results of the analysis revealed a significant association between CO2 levels (665.33 ± 207,20 ppm) and sleep efficiency (86,71 ± 3,11 %). High levels of CO2 were found to be associated with lower sleep efficiency, leading to sleep disturbances and irregular sleep patterns. Other environmental factors, such as ventilation rates, were also relevant to sleep efficiency.

“… 4 , 5 During the COVID‐19 pandemic several lockdowns were implemented worldwide, resulting in most of the global population being confined to their own residences with its indoor air. This fact, combined with the importance of IAQ for sleeping quality and next‐day performance, 6 , 7 , 8 emphasizes the importance of research on IAQ in residential buildings.…”

A review of critical residential buildings parameters and activities when investigating indoor air quality and pollutants

Indoor air in residential dwellings can contain a variety of chemicals, sometimes present at concentrations or in combinations which can have a negative impact on human health. Indoor Air Quality (IAQ) surveys are often required to characterize human exposure or to investigate IAQ concerns and complaints. Such surveys should include sufficient contextual information to elucidate sources, pathways, and the magnitude of exposures. The aim of this review was to investigate and describe the parameters that affect IAQ in residential dwellings: building location, layout, and ventilation, finishing materials, occupant activities, and occupant demography. About 180 peer‐reviewed articles, published from 01/2013 to 09/2021 (plus some important earlier publications), were reviewed. The importance of the building parameters largely depends on the study objectives and whether the focus is on a specific pollutant or to assess health risk. When considering classical pollutants such as particulate matter (PM) or volatile organic compounds (VOCs), the building parameters can have a significant impact on IAQ, and detailed information of these parameters needs to be reported in each study. Research gaps and suggestions for the future studies together with recommendation of where measurements should be done are also provided.
