Sisäil

Sisäil refers to the air quality within indoor spaces. It encompasses the physical, chemical, and biological characteristics of the air in buildings, homes, and other enclosed environments. Poor indoor air quality, often referred to as "sisäilmaongelma" or "sisäilmaongelmat" in Finnish, can arise from a variety of sources, including building materials, furnishings, human activities, and outdoor pollutants that enter the building. Common indoor pollutants can include volatile organic compounds (VOCs) from paints and adhesives, particulate matter from dust and combustion, biological contaminants like mold and bacteria, and gases such as carbon monoxide and radon.

The impact of sisäil on human health can range from mild discomforts like headaches and eye irritation to more severe respiratory problems and allergic reactions. These symptoms are often collectively referred to as Sick Building Syndrome (SBS) when a direct cause cannot be identified but symptoms are relieved upon leaving the building. Identifying and mitigating the sources of poor sisäil is crucial for creating healthy and comfortable indoor environments. This involves proper ventilation, controlling moisture to prevent mold growth, choosing low-emission building materials, and regular cleaning. Monitoring and assessing sisäil is an important aspect of building management and public health.
