The Effects of Bedroom Mechanical Ventilation on Health and Sleep Quality

Sleep is essential for overall health and well-being. The quality and efficiency of sleep are strongly influenced by the sleep environment, including indoor air quality. This study investigates the influence of mechanical ventilation on bedroom air quality during sleep and its impact on sleep efficiency and quality. Objective and subjective measurements were conducted to assess the effects of operating a mechanical ventilation system. The results showed that both objective and subjective evaluations of sleep quality demonstrated the improvement of sleep quality when the ventilation system was in operation. Conversely, when the ventilation system was not used, the objective indicator of sleep efficiency was lower, indicating an increase in sleep disturbances. These findings suggested that maintaining low CO2 concentrations could enhance the sleep efficiency and quality. These findings provide foundational insights for further studies on appropriate sleep environment.
