Is the air we breathe while sleeping conditioning our sleep quality? In: 14th International Conference on Urban Health – Health Equity: the new urban agenda and sustainable development goals, Coimbra (Portugal), 2829 September 2017.http://hdl.handle.net/10400.21/7454Human exposure to air pollution: high variability of air pollutants concentration within a city; people spend more than 90% of their time in indoor environments; high variability of patterns of spaces’ occupation within the population. What do we know now? Sleep has a vital role in human welfare; low ventilation rates; breathing area closer to potential sources of pollutants; lack of studies about exposure during sleep. Why sleep matters – the economic costs of insufficient sleep: sleep has an overall impact on the countries’ richness; lower productivity levels and higher mortality risks related to insufficient sleep can result in substantial economic losses to modern economies; insufficient sleep among its populations cost the 5 OECD countries under consideration (USA, UK, Japan, Germany and Canada) up to $680 billion of economic output lost every year. The aim of this study: Do indoor air quality influences sleep quality?engEnvironmental healthSleepSleep qualityconference object
