Field Survey Analysis of CO₂ Concentration and Its Impact on Sleep Efficiency in University Dormitory

Abstract

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.
