How to reduce the health risks of air pollution

A summary of research published in the European Respiratory Journal

The evidence about the dangers of poor air quality is increasing each year. As we learn more about how harmful it can be, it has become clear that we need practical advice on how we can reduce our personal risk. This article collects together the research published on this topic and provides recommendations on what can be done to protect our lung health from polluted air.

What do the authors recommend?

Recommendations to lower the risk of outdoor air pollution include:

  • Use active options for travelling, such as walking and cycling, instead of travelling by car or other motorised forms of transport. High exposures to traffic-related pollution can occur within vehicles.
  • Choose routes that avoid busy roads.
  • Adjust driving style and car settings. This includes avoiding fast accelerations and heavy breaking and, in areas of heavy pollution, keeping windows closed and keeping the fan set to internal circulation only.
  • Pay attention to the air quality, particularly when exercising. Avoid areas of traffic and plan your activity based on air quality forecasts. Stop exercising if you have concerns about chest tightness or wheezing.

Recommendations to lower the risk of household air pollution include:

  • Use clean fuels to cook with, such as electricity, solar cookers, biogas (methane), or liquid petroleum gas (LPG), where possible. Houses should also be ventilated during cooking and efficient cook stoves used.

Recommendations to lower your own personal risk:

  • Look after your lung health – treat and manage any lung conditions you may have.

Why is this important?

These recommendations provide a list of practical things people can do to lower the risk of harm caused by air pollution. In the full article, the authors grade the recommendations based on the strength of the evidence – some recommendations have more evidence to support them than others. Nonetheless the authors believe that all the recommendations can have a positive impact as even the smallest amounts of air pollution can be harmful.
