You may know that living close to green spaces can benefit our lifestyle by reducing stress and encouraging us to be more active, but did you know that they might also benefit your asthma
How green spaces can boost air quality
New research from the US has found that inner-city children with asthma experience fewer days with asthma symptoms – a cough, breathlessness, wheeze or tight chest – the closer they live to parks and green spaces.
We know that pollution is an asthma trigger. Two thirds of people with asthma telling us poor air quality makes their asthma worse. If you live in a city, pollution is a trigger that is hard to avoid.
But green spaces could help.
Previous research has shown that leafy greenery improves air quality, absorbing some of the pollutants that can trigger asthma symptoms. Trees, shrubs and turf remove smoke, dust and other pollutants from the air. One tree can remove 26 pounds of carbon dioxide from the atmosphere annually, which is equal to the amount produced by driving a car 11,000 miles.
Get fit in the park
There’s another reason why parks might also good for asthma: from walking trails to tennis courts, bike tracks to outdoor gyms – they have lots of features that can inspire us to get fit. And exercise can help you take control of your asthma symptoms. It can help improve how your lungs work, keep your weight healthy – there’s a link between link between carrying extra weight and asthma – and lift your mood, so you feel more confident about managing your asthma.
What does this study mean for you?
This is only a small study looking at children with asthma, aged between three and 12, who live in the inner-city of Baltimore in the US. So, what’s needed now is research with more participants to see if the findings hold true in different populations, in different parts of the world and in different age groups.
In the meantime, there are proven ways to take care of your asthma if you live or work in a high-pollution area: like making sure you or your child take preventer medicine every day and avoiding traffic-clogged main roads when you’re out and about.
