A research in the Archives of Disease in Childhood indicates that cooking gas may increase the chances of respiratory illness amongst children.
The researchers surveyed parents of 426 children in Hong Kong and found that children aged below 6 years of age, who were not yet going to school and spent most of the time indoors, were more likely to develop respiratory problems.
A greater frequency of gas cooking was associated with a higher risk of respiratory illness as frequent use of gas cooking produces higher levels of nitrous oxide.
