<h3><u>Explanation:</u></h3>
Indoor air pollution is a very serious topic both in cities as well as rural areas. In the rural areas, the persons usually have their kitchen inside house, with minimal ventilation system and the smoke from burning coal or wood all accumulate inside house which contributes to most of indoor air pollution.
In cities, the outside air is itself polluted. Else, the smoke from burning chimneys, or smoking cigarettes also contribute to this pollution. Nevertheless, the particulate matters like dust and dirt are important sources in both these places.
Indoor air pollution is the main cause for COPD or bronchitis in non smokers. But most importantly, COPD indirectly precipitates to cardiac arrest or cardiac failure. Ingestion of kerosene vapour or soots and smokes actually increases the muscle fatigue, which can lead to muscle weakening. This leads to muscular discomfort and finally a stroke or IHD can precipitate.
