12 January 2023, Webinar – Sleeping Environment IAQ and Sleep Quality

Our bodies need good rest and sleep as part of regular recuperation to enable us to perform our normal activities in life.  Sleep is an integral part of human life and the importance and significance of good bedroom IAQ, indoor air pollution, ventilation as well as bedroom thermal environment during sleep cannot be emphasized more. Yet, there is a paucity of information in the scientific literature in this regard, especially pertaining to IAQ in sleeping environments and sleep quality.  Are our bedrooms adequately ventilated at all times to maintain good IAQ?
