Bedroom Environmental Quality Impacts our Sleep, Health and Well-being

Chair(s): Chandra Sekhar (National University of Singapore, Singapore), Pawel Wargocki (Technical University of Denmark)

Sleep is an integral part of human life and the importance and significance of good Bedroom Environmental Quality (BEQ) and Sleep Quality cannot be emphasized more. When compared with research findings on IEQ and its impact on human comfort, health and well-being during our awake state in different types of buildings and transportation environments, there is a paucity of such information in the scientific literature pertaining to similar impacts in sleeping environments. We spend more than 90% of our time indoors and sleep for about a third of our lives in sleeping environments. Are our bedrooms adequately ventilated at all times to maintain good IAQ? Is the thermal comfort of our bedroom acceptable across all seasons? Is our bedroom environmental quality affecting our sleep quality, and thereby our health and well-being? Are we even aware of these associations? What do the various international standards say about thermal comfort, IAQ, visual and acoustic aspects of our sleeping environments?

A workshop on this topic included some of the above questions and was presented as a webinar on 12 January 2023, which was organised by ASHRAE and AIVC. There has been a growing international interest on this subject within the last 5 years that has resulted in many new top peer-reviewed journal publications. This Workshop at IEQ 2025 in Montreal aims to continue the ongoing discussions about BEQ and Sleep Quality by incorporating the current state-of-the-art research, new knowledge gained and call-to-action for enhanced ventilation and IEQ standards in sleeping environments.
