Household air pollution (HAP) has been recognized as one of the lethal causes of millions of premature deaths every year, victimizing mainly children and women. Literature suggests that transition to modern cooking fuels such as electricity, biogas from the conventional ones, for instance, fuelwood, coal, can reduce HAP, thus minimize the likelihood of respiratory health problems among household members. This study explores whether cooking fuels has an impact on children's respiratory health in the context of Nigeria, and in particular, whether modern cooking fuels can be a solution to this problem. By using the children recode of the survey data collected by the Demographic and Health Survey (DHS) for the year 2018, this study finds support to the claim that modern cooking fuels can reduce the probability of Acute Respiratory Infections (ARI) symptoms among children aged below 5 years in Nigeria. This probability is also found contingent on the age, gender, and education of the household heads. However, with regards to individual fuel types, the result seems inconclusive in some instances, mostly due to a lack of observations. The policy implication is that to reduce ARI among children, households should be encouraged to adopt modern cooking fuels, and this should follow with increasing education and empowerment opportunities for women in the household.
