Asthma could be worsened by energy-efficient homes, warns study
Lack of ventilation caused by better insulation could create spike in indoor pollutants, research warns
The number of Britons with asthma could almost double by 2050 because the air inside homes is becoming more polluted as they become more energy-efficient, a new report warns.
The trend towards airtight houses could also worsen allergies as well as breathing problems, and even exacerbate lung cancer and heart problems, according to a leading expert in indoor air quality.
Airborne pollutants created by cooking, cleaning and using aerosols such as hairsprays will increasingly stay indoors and affect people’s health as homes are made ever more leak-proof to help meet carbon reduction targets, a report by Professor Hazim Awbi claims. Small amounts of chemicals found in detergents can stay on the fibres of washed clothes, be emitted into the air and combine with particulate matter from logs burned in a real fire, for example.
