According to a recent research paper, commonly used household items should be labelled with a warning that they raise the risk of asthma.
A new study carried out by Smartline and funded by the European Regional Development Fund, found evidence that there are a group of chemicals mixed in a wide range of products in people’s homes increases the risk of asthma.
The authors suggest that product labels should reflect this danger and advise consumers to ventilate their houses while using them.

The work analyzed 12 studies into Volatile Organic Compounds (VOCs), which are emitted as gases from certain solids or liquids.
VOCs are emitted by a wide array of products, including some that are widely used as ingredients in household products.
Paints, varnishes and wax, many cleaning, disinfecting, cosmetic, degreasing and hobby products may all contain ingredients that emit VOCs. Concentrations of many VOCs are consistently up to ten times higher indoors than outdoors.
The research, led by the University of Exeter, provides collective evidence that, for adults the composition of many VOCs found in household products increase the risk of asthma.
These particles and compounds vary from by household, caused by factors like leaks in building fabric, heating and ventilation systems, damp, smoking, cleaning products and aerosols.
The findings uncover that high exposure to VOCs also causes wheezing and shortness of breath for people without a respiratory illness.
Asthma is a complex disease, impacting around 10 per cent of the UK’s adult population – one of the highest rates in the world. The new systematic review published in Environmental Research, is the first of its kind to investigate the relationship between air pollutants and the risk of asthma for people in higher-income countries.
One highly regarded study found a 15 per cent increased risk of asthma with exposure to Limonene, a naturally occurring aliphatic compound found in products like shampoos, detergents and air fresheners. Wood and kitchen paint also seem to increase symptoms.
Our findings are concerning because we often use multiple products at home and people are unaware of the dangers. For example, the findings show the risk of asthma to increase by 40 per cent for people exposed to five VOCs, while another study found that people without asthma are also at risk of wheezing attacks, especially when exposed to products containing benzene, a common chemical used to make other industrial chemicals and as a solvent in many everyday products
said Cheryl Paterson, Lead Researcher, University of Exeter.
This research highlights the risks that indoor pollutants can have on people’s respiratory health, especially for vulnerable people who already experience health problems.

As people are spending more time indoors, our research is particularly important to inform new public health strategies to reduce ashthma. To raise awareness of the potential health risks, industry and policymakers need to use more explicit health warnings on product labels. This should include better health messaging and advice about using and storing thee chemicals in the home, including proper ventilation while in use.
