What do health studies show?

Most people think of respiratory illnesses as the effect on our health of air pollution. However, scientific studies have linked air pollution to a range of health outcomes, which vary according to the key stages of development of the human life-cycle.

For example, in the womb air pollution is linked with lower birth weights of babies. In toddlers, development problems are increased due to air pollution with increased rates of wheezing and coughing. Slower development lung function is observed in children, alongside asthma and the onset of Atherosclerosis (a hardening of the artery walls), whilst in adults a wide range of symptoms including heart attacks, the acceleration of lung function decline, Type 2 diabetes, asthma and lung cancers are now all linked to air pollution. For the elderly, exposure to poor air quality increases the probability of poor cognition, strokes and heart failure.
