Air pollution, from traffic exhaust to your gas cook-top, can be damaging our lungs and your general health. When we breathe in certain air pollutants, the risk of developing conditions like asthma, heart or lung disease and cancer can increase.

World Health Day is celebrated annually and each year draws attention to a specific health topic of concern to people all over the world. The date of 7 April marks the anniversary of the founding of WHO in 1948.
