What disease is most commonly associated with household air pollution?

Household air pollution is primarily linked to respiratory problems, and pneumonia is one of the most common diseases associated with exposure to such poor air quality. In many situations, particularly in low-income countries, indoor air pollution arises from the use of solid fuels for cooking and heating, which releases harmful pollutants. These pollutants can exacerbate existing respiratory issues and significantly increase the risk of pneumonia, especially in vulnerable populations such as children and the elderly.

Furthermore, pneumonia can be caused by infections that thrive in environments with poor air quality, where contaminants can damage the lungs and the immune system's ability to respond effectively to pathogens. While asthma, cancer, and cardiovascular diseases are also influenced by air pollution, pneumonia stands out as a direct result of the acute and chronic exposure to harmful indoor pollutants linked to household conditions. This context helps establish the strong association between household air pollution and pneumonia as the most commonly recognized disease.
