Gas cooking leads to higher asthma risk
COOKING with gas stoves is responsible for an estimated 12 per cent of childhood asthma in Australia, according to new research.
Environmental health scientist Luke Knibbs led research which investigated the connection between childhood asthma and two common indoor exposures — gas stoves and damp houses.
Researchers calculated about 12 per cent of childhood asthma in Australia could be attributed to gas stove exposure and 8 per cent to household dampness.
“I don’t think that there is the same level of awareness for the link between gas appliances and asthma as there is for damp housing,” Dr Knibbs, of the University of Queensland, said.
Dr Knibbs said cooking with gas released chemicals, such as nitrogen dioxide and formaldehyde, which could cause inflammation in the airways and exacerbate asthma.
But the researchers found the amount of childhood asthma linked to gas cooking could be cut from 12 per cent to 3 per cent if all homes with gas stoves were fitted with rangehoods to vent emissions outdoors.
