Session Abstract


Sleep is an integral part of human life, the deprivation of which can have adverse impact on our normal activities and health. Adequate, consistent and quality sleep can improve longevity and lead to an increase in global life expectancy. The ongoing global pandemic, in which our homes have become our predominant indoor environment, has indeed given a new perspective to adequate and quality sleep. In a highly digitalised world where the line between work, family and social life is getting increasingly blurred, it has become rather challenging to find the few hours of quality sleep, especially in a conducive sleeping environment. It is important to acknowledge that sleep quality can be significantly affected by the thermal comfort, ventilation and IAQ in the bedroom. There is very little information in the scientific literature concerning these aspects. 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 IAQ affecting our sleep quality? Are we even aware of these associations? What do international standards say about bedroom ventilation and IAQ?


This workshop will provide a framework to address the above questions and encourage an open discussion on the need and call to action towards enhancing the IAQ in sleeping environments across different climates. Short presentations will be made by domain experts to introduce some of the specific aspects of this workshop and provide an appropriate context and framework for a wider discussion by all the participants.
