Environmental sleep disruptors: the role of thermal comfort and CO2 levels

Introduction: Sleep is a vital physiological process essential for physical recovery, cognitive function, and emotional balance. Its quality is influenced not only by individual and behavioral factors but also by environmental conditions in the sleep setting. Among these, thermal comfort and indoor air quality, particularly ambient temperature and carbon dioxide (CO2) concentration, are increasingly recognized as important modulators of sleep architecture and continuity. Suboptimal thermal conditions and elevated CO2 levels may impair sleep efficiency, reduce total sleep time, and increase the frequency of nocturnal awakenings. This study presents preliminary data from the HypnosAir Project (www.hypnosair.com), which investigates the impact of indoor environmental conditions on sleep quality.
