Resumo(s)

Introduction: Poor air quality is a recognized risk factor for respiratory and cardiovascular diseases. Nocturnal exposure to air pollutants may further impair sleep quality, compounding health risks and increasing emergency healthcare utilization. The interplay between nighttime environmental stressors and sleep disruption remains underexplored in the Portuguese context. With this work, the authors aimed to examine the association between nocturnal air pollution, sleep quality indicators, and emergency department visits for respiratory and cardiovascular complaints across multiple regions in Portugal.

Descrição

Data were obtained from open-access sources, including air quality metrics from the Portuguese Environmental Agency’s QualAr platform, population-level sleep indicators from EUROSTAT and the National Institute of Health Doutor Ricardo Jorge (INSA), and health service utilization records from the Portuguese Ministry of Health databases. HypnosAir project (PTDC/CTA-AMB/3263/2021/BI/12M).
