In July 2024, a webinar explored how the UK government could address indoor air quality (IAQ) concerns, revealing the significant consequences of neglecting this critical issue. Reports indicate that people in developed nations spend around 90% of their time indoors. Given this, how much do our indoor environments influence health, and what steps can be taken to improve air quality? Paul Beech, Commercial Director at thermal break specialist Armatherm, highlights the importance of maintaining healthy indoor conditions and tackling factors that may harm occupants’ wellbeing.
The quality of housing in the UK has been an increasing concern since the 1990s as stricter building regulations emerge. Rapid housing developments following the Second World War and during the 1980s, particularly under the ‘Right to Buy’ initiative, led to the construction of homes with insufficient insulation.
These older homes often demonstrate poor IAQ due to the accumulation of harmful pollutants. Common issues, such as damp and mould, significantly affect indoor environments. Poor air quality can lead to long-term health problems, including asthma, respiratory infections, and even heart disease and cancer. Especially in multifamily buildings, thermal bridges can cause condensation that provides the moisture mold needs to grow.
A growing concern is the prevalence of ‘forever chemicals’—persistent pollutants linked to severe health risks. Despite these dangers, the UK lacks adequate chemical regulations, leaving many people unaware of how to manage exposure to such substances effectively.
The Royal Society of Chemistry recently called for improved regulation of these harmful pollutants. Many households inadvertently worsen IAQ through everyday activities, such as cooking or cleaning, without implementing measures to reduce pollutant levels. Simple steps, like using extractor fans or ventilating rooms by opening windows, can make a noticeable difference, though access to ventilation systems remains inconsistent across homes.
Understanding the effects of indoor pollutants on health is crucial. Providing consistent access to clean air through proper ventilation, extractor fans, and filtration systems where necessary can mitigate the risks associated with poor IAQ. These measures not only promote healthier living conditions but also help prevent the spread of infectious diseases.
