Mosquito coils may trigger breathing disorders in children

Paediatricians have warned that burning mosquito coils indoors can trigger breathing disorders in children. The smoke and pollutants released can irritate airways, particularly in poorly ventilated spaces. Children are considered more vulnerable due to their smaller, developing airways and the longer periods they spend asleep.

A study published in the journal CHEST found that burning mosquito coils in a closed bedroom for six hours resulted in high levels of fine particulate matter, with average PM2.5 concentrations reaching 1,031 micrograms per cubic metre and peaks of 1,613 micrograms per cubic metre. Carbon monoxide levels also averaged 6.50 parts per million during the study. Researchers noted that improved ventilation helped reduce pollutant concentrations.

The World Health Organization (WHO) has highlighted the broader risks of household air pollution, noting it was responsible for 2.9 million deaths globally in 2021, including over 309,000 deaths among children under five. While WHO figures include various sources like cooking and heating fuels, the health risks of indoor smoke remain a significant concern, especially in regions like Nigeria where malaria burdens are high.
