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.
