What Every London Parent Should Know

When we think about keeping our children healthy, we often focus on nutrition, sleep, immunisations and physical activity. However, there is another important factor that can affect children's health every day: the air they breathe.

Children are particularly vulnerable to air pollution because their lungs are still developing and they breathe more rapidly than adults. Research continues to show links between air pollution and respiratory conditions, including asthma and chest infections.

For families living in London, understanding air quality and taking simple steps to reduce exposure can make a meaningful difference.

What Is Air Pollution?

Air pollution is made up of tiny particles and gases that enter the air from sources such as:

• Road traffic
• Construction works
• Industrial activities
• Wood-burning stoves
• Domestic heating
• Diesel vehicles

Many pollutants are completely invisible.

This means air can look clean whilst still containing harmful particles.

Why Are Children More Vulnerable?

A child's lungs continue developing throughout childhood.

Because children:

• Breathe faster
• Spend more time outdoors
• Have developing immune systems
• Have smaller airways

they can be more affected by poor air quality than adults.

Signs Pollution May Be Affecting Your Child

Some children may experience:

• Persistent coughing
• Wheezing
• Breathlessness
• Runny noses
• Eye irritation
• Increased asthma symptoms
• More frequent chest infections

If you have concerns about your child's breathing, speak with your GP or health visitor.

Practical Ways to Reduce Exposure

🚶 Choose Quieter Routes

Walking one road back from a busy main road can significantly reduce exposure to vehicle emissions.

🌳 Use Green Spaces

Parks and green spaces often have better air quality than congested roads.

🪟 Ventilate Your Home Properly

Open windows when outdoor pollution levels are lower.

Balance fresh air with weather conditions and local traffic.

🚭 Maintain a Smoke-Free Environment

Never smoke inside your home or vehicle.

🚗 Avoid Idling Vehicles

If collecting children from nursery or school, switch off your engine while waiting.

Air Quality and Asthma

If your child has asthma:

• Ensure inhalers are up to date.
• Follow your asthma action plan.
• Check pollution levels during high-risk periods.
• Speak to your GP if symptoms worsen.

Housing Conditions Matter Too

Poor housing conditions such as damp, mould and overcrowding can worsen respiratory illnesses and make pollution-related problems more severe. Children living in poorer quality housing are often affected disproportionately.

What Can Communities Do?

Real change often starts locally.

Parents can:

• Support clean air initiatives
• Encourage active travel where possible
• Report housing concerns
• Participate in community consultations
• Advocate for safer streets around schools and nurseries

Every child deserves the opportunity to grow up in a healthy environment.
