The number of deaths from indoor air pollution is even higher than that from all other kinds of pollutants combined. <br />A recent report from the UN Environment Programme says that four-point-three million people die from indoor air pollution every year, out of the seven million deaths annually caused by all kinds of atmospheric pollution. <br />The main cause cited was prolonged exposure to solid fuels such as coal for cooking, which can lead to respiratory conditions or heart disease. <br />The vast majority of deaths from household air pollution are in Southeast Asia and Africa, where people are more reliant on coal for fuel. <br />Experts say that airing out rooms is important,... as poor ventilation could cause pollutants to accumulate.
