Go Green: Living Near Green Spaces can Boost Your Child’s Lung Health

Let’s Go Green: Living near green spaces is good for your child’s lung health. So, hurry up, start moving closer to green areas to boost your child’s lung function.

Moving near green spaces can boost your child’s lung health, suggests a new study.

Getting children closer to green spaces as they grow up could improve their lung health, according to a study published in the European Respiratory Journal.

Exposure to Greenspaces Promotes Early Childhood Development
Children living in a residential location with more vegetation and richer natural environments showed better overall development than their peers with less greenspace.

The research found that children tended to have better lung function if their exposure to vegetation close to their homes increased in the first ten years of life.

Researchers say their findings support the idea of families moving to greener areas, but also highlight the need to create more green spaces in urban areas.

The research was led by Dr Diogo Queiroz Almeida from the University of Porto, Portugal. It included 3278 children living in and around Porto.

Green Spaces Linked to Lower Rates of Obesity, Hypertension
In kids, the more green space there was around schools was consistently associated with lower systolic blood pressure and with lower odds of hypertension (high blood pressure).

The team used satellite data and maps to assess the amount of vegetation in the home surroundings, and geographical information systems (technology for comparing the geographical locations of different things) to determine the distance between children’s home addresses and their nearest park, public garden or other public green spaces when they were born and when they were four, seven and ten years old.

They gauged children’s lung function according to their forced vital capacity (FVC). This is the maximum amount of air a person can blow out after taking in the deepest possible breath. FVC can indicate how well the lungs are working and help diagnose lung conditions like asthma.

Green Spaces Found to Increase Birth Weights: Study
Mothers who live near green areas deliver babies with significantly higher birth weights.

The researchers found that children whose home surroundings became greener between birth and their tenth birthday, either due to house moves or due to environmental changes, tended to have better lung function.

Is Green Space Good for Health?

Dr Queiroz Almeida said: “Our research suggests the greener, the better. These improvements are modest at around two per cent. However, if we look at the whole population, making our neighborhoods greener could have a considerable impact.

Green Spaces Down Racial Disparity in COVID Infection Rates
Study examined the relationship between the supply of green spaces and reduced disparity in the COVID-19 infectious disease rates.

“We looked at factors like physical activity and air pollution, but the link between lung function and moving closer to green space remained, even after we took these into account. It could also be that getting closer to nature reduces stress, which can improve physical health, or it might have a positive effect on children’s microbiome – the community of different bacteria that live in our bodies.

“We found that living in greener neighborhoods as children grow up is more important for their breathing than living in a green area when they were born. This may be because babies spend much less time outdoors than children.”

The researchers also looked at how close children lived to rivers or the sea – so-called ‘blue space’ – but they found no link with children’s lung health. However, in this study less than one per cent of children lived within 800m of blue space, so a link cannot be ruled out for shorter distances.

Dr Queiroz Almeida added: “This research strengthens the evidence supporting the benefits of green spaces on respiratory health. Moving to greener areas may be a possible strategy to improve children’s lung function. However, house prices often dictate where families live; and many cannot afford to live in greener neighborhoods.

“To reduce health inequalities, we need to make our cities greener, especially in areas where there is little or no green space. In particular, we need to involve children and their carers to make sure our parks and gardens suit their needs.”

The researchers will continue to study the role of green and blue spaces in other areas of children’s health. They are also using focus groups to understand how and why green spaces are used by younger people.

Professor Marielle Pijnenburg is head of the pediatric assembly of the European Respiratory Society and was not involved in the research. She says: “We know that early childhood is a crucial time for lungs to grow and develop, and that a child’s environment and the air they breathe can have an impact on their lung health for the rest of their life. This study suggests that making sure our children grow up close to parks, gardens and green spaces could help improve their lung health, although as the authors said the mechanisms for this are unknown and may be complex. This finding contributes to a growing number of studies that show health benefits of making our neighborhoods greener and healthier.”
