Abstract:The objective of this research was to explore the impacts of heightened CO2 concentrations on human health and wellness in an underground confined space. A total of 180 participants were subjected to CO2 concentrations ranging from 1000 to 10000 ppm within a confined underground environment. The study assessed not only subjective perceptions and physiological responses but also cognitive performance, integrating novel measures such as emotion, skin conductance (SC), and heart rate variability (HRV).
