Dirty air is a major cause of ill health and early death in our communities.
In towns and cities, road vehicles are the main source of air pollution.
This can contribute to a wide range of illnesses and conditions, including lung and heart diseases, some cancers, strokes and asthma too.
And we are still learning more about how air pollution affects our health.
Recent studies have made links to dementia and reduced cognitive function (mental processes such as reasoning, memory and language).
Air pollution affects everyone’s health, from birth to death.
Health damage caused by air pollution can begin as early as a baby’s first few weeks in the womb.
The impacts can be experienced at every stage of life and even contribute to an early death.
And the most vulnerable in society are hit hardest – children, older people and those already in poor health.
Everyone is at risk. But people who spend more time in areas with a high concentration of air pollution are most affected – which can include drivers.
What happens when we breathe invisible gases, soot and fine particles deep into our lungs?
Just a few hours’ exposure to air pollution can irritate your eyes, nose and throat. But a few years’ can lead to you developing heart and lung disease.
Children’s lungs develop throughout their childhood. So children with asthma who are exposed to air pollution are likely to have more asthma attacks. And those attacks may be more severe.
If you already have a lung or heart condition, breathing in polluted air can make it worse. Even short-term exposure to air pollution can make lung conditions worse.
