Avoid air pollution when you can

Here are five tips for how to avoid polluted air:

• Use quieter streets when you’re on a bike or on foot to lower your exposure to air pollution by 20%.
• Car drivers can be exposed to twice as much air pollution as pedestrians and nine times more than a cyclist: so avoid sitting in your car in heavy traffic where possible.
• Walk on the inside of the pavement or on the opposite side to queuing traffic to stay as far away as possible from exhaust fumes.
• There are about ten to 20 high pollution days a year when it’s better to avoid working out too hard if you have a heart or lung condition. Check day-to-day pollution levels in your area.
• Blocking out air pollution helps, so close windows during rush hour if you live or work on a busy street.
