Breath is life, and yet the importance of lung health is under-recognized, especially in women. No wonder then that lung diseases account for more than 16 percent of deaths among women worldwide. Exposure to tobacco smoke and indoor air pollution, from using solid fuels for cooking and heating, are the two leading risk factors that have an impact on women's lung health much more than that of men, especially in low/middle income countries. Each of these pollutants kills more than 1.5 million women worldwide every year.
