Open the window when bathing, cooking or cleaning to cut the health risks from “indoor pollution” experts say today.
The National Institute for Health and Care Excellence (Nice) said pre-school children, pregnant women and the elderly could be particularly vulnerable to the combination of fumes and poor ventilation.
New draft guidance urges the public to use extractor fans or open windows while cooking, drying clothes inside, and using household sprays, solvents and paints.
Homes should also be ventilated when using candles, having a bath or shower, and using open solid-fuel fires.
The guidance says windows should be opened where possible, and if not, extractor fans should be used.
The advice is for everyone but particularly affects vulnerable groups including people with lung conditions such as asthma.
The guidance also urges pregnant women to reduce their use of aerosols and household cleaning sprays.
Gill Leng, deputy chief executive and director of health and social care at Nice, said: “Evidence shows that homes with poor air quality are linked to an increase in risk of health problems.
“Poor ventilation leads to a build-up of pollutants which can exacerbate illnesses such as asthma.
“Councils are in a good position to raise awareness among the general public.
