We all breathe air. It’s an essential exchange that sustains our existence. Yet, while Brits often discuss the weather, we rarely address the air quality that profoundly affects our health. It’s time to change that conversation.

As someone with asthma, I am acutely aware of the air I breathe. My body responds to pollution, sensing the relief of clean, woodland air and the oppressive heaviness of urban environments. Asthma affects about 8 million people in the UK – 12% of the population –who struggle daily with this respiratory condition. Alarmingly, more than 90% of children in the UK inhale toxic air every day.

The World Health Organisation (WHO) has set limits on pollutants like nitrogen dioxide (NO2), sulphur dioxide (SO2), and carbon monoxide (CO) to prevent health crises. However, in dense urban areas, NO2 levels can exceed safe limits, sometimes reaching over 500 µg/m3. This is far higher than the recommended government guidelines of a maximum of 40 µg/m3, and the WHO’s guide of 10 µg/m3.

This pollution originates from traffic, gas appliances, and industrial emissions. In rural areas, chemical fertilisers release these pollutants, exacerbating respiratory issues. By opting for organic products, we can help reduce nitrogen levels, benefiting the soil, water and air.

So, what can we do to help improve the quality of the air we all breathe?

Transport

Consider cycling or walking to work, or using public transport. Avoid idling your car, and engage with others to raise awareness about its dangers.

Home environment

Common household items significantly impact air quality. Switching to chemical-free cleaning products can make a big difference. Visit a local refill shop to start your journey to a cleaner home environment.

Products

Everything from carpets to furniture releases chemicals into the air. When purchasing new items, opt for those made with natural ingredients, or buy second hand. For example, choose natural roll-on deodorants instead of aerosols.

Ventilation

Air needs space to circulate. Regularly open windows to reduce indoor air pollution and spend more time outdoors to breathe fresher air.

Plant life

Trees and plants naturally filter air. If you have access to green space, consider planting more greenery to enhance air quality. You could also bring nature indoors with houseplants to help improve the air quality inside your home.

To monitor pollution in your area, check out resources like PurpleAir. Consider getting a sensor and becoming a citizen scientist to help track local air quality.

By making these small changes, we can collectively improve the air we breathe and ensure healthier lives for ourselves and future generations.
