Children closer to nature ‘have lower risk of behavioural problems’, study finds

--Advertisment--

Exposure to green space could be more important than ever for children now the Covid-19 lockdown has ended, a new study suggests.  

Researchers compared the mental health of more than 3,000 children in the London area with their proximity to green spaces.

Those who were closer to woodlands had better cognitive development and a lower risk of emotional and behavioural problems, they found. 

Worryingly, data was gathered prior to the pandemic, meaning the health problems were likely exacerbated by a lack of natural space during lockdown.  

The study could influence planning decisions in urban areas around the world, according to the authors at University College London and Imperial College London. 



Building new homes in close proximity to grass, trees and woodland could optimise ‘benefits linked to cognitive development and mental health’, they say.

WALKING AND MENTAL HEALTH 

Walking improves well being and helps fight stress and depression 

– Walking, like other physical activities, releases endorphins which improve mood and reduce stress and anxiety 

– Feeling fitter and controlling weight helps improve your body image and confidence 




– Active people have a reduced risk of suffering clinical depression 

– Walking in a group is a sociable activity that can help improve mental health and overcome feelings of isolation 

– Spending time in the outdoors and in contact with the natural environment – for example by walking in parks, woodland and green spaces – can have a positive effect on mental health

It is already estimated that one in 10 of London’s children and adolescents between the ages of five and 16 suffer from a clinical mental health illness. 



This is leading to excess costs of between £11,030 and £59,130 annually for each child, according to the government, paid for by social services and other agencies – so more green space could be the answer. 

The authors stress the importance of nature for children and adults to boost our health, although they didn’t specifically determine that one factor causes the other. 

‘One possible explanation for our findings may be that audio-visual exposure through vegetation and animal abundance provides psychological benefits, of which both features are expected in higher abundance in woodland,’ said study author Professor Kate Jones at University College London (UCL). 

‘Even though our results show that urban woodland is associated with adolescent’s cognitive development and mental health, the cause of this association remains unknown. 

‘Further research is fundamental to our understanding of the links between nature and health.’ 




Interestingly, not every type of natural environment may contribute equally to physical and mental health benefits, the research also found. 

For the study, the academics used anonymised longitudinal data relating to 3,568 children and teenagers, aged nine to 15 years, from 31 schools across London between 2014 and 2018.

Ages nine to 15 is a key time in the development of children’s thinking, reasoning and understanding of the world, according to the team.

DOCTORS TOLD TO PRESCRIBE WALKS 

Doctors have been told to prescribe green spaces to boost patients’ physical and mental health.



In a speech in July 2020, Environment Secretary George Eustice said instead of simply handing out pills, GPs and other health professionals could start issuing ‘green prescriptions’ telling patients to visit Britain’s beauty spots.

Under the £4 million scheme, doctors are also urging people to do gardening, join cycling and walking groups, take part in outdoor ‘green gym’ sessions and even help plant trees in their local area.

The plan could also be used to send vulnerable people – such as care home residents – on coach trips to Britain’s national parks and areas of outstanding natural beauty.

In an online speech to the Green Alliance, Mr Eustice pledged that nature will be at the heart of the efforts to reboot the economy following the pandemic.

Mental health and overall well-being came from self-reported questionnaires, covering areas including emotional problems, conduct, hyperactivity and peer problems. 

Satellite data was used to help calculate each child’s daily exposure rate to natural environments within 164 feet (50 metres), 330 feet (100 metres), 820 feet (250 metres) and 1,640 feet (500 metres) of the home and school. 

Natural environments were divided into what planners call green space (woods, meadows and parks) and blue space (rivers, lakes and the sea).

Green space was also separated further into grassland and woodland.    

After adjusting for other variables, higher daily exposure to woodland (but not grassland) was linked with higher scores for cognitive development, and a 17 per cent lower risk of emotional and behavioural problems two years later.



A similar but smaller effect was seen for green space, with higher scores for cognitive development. 

This was not seen for blue space, although access to blue space in the cohort studied was generally low, the team pointed out. 

Examples of variables considered included the young person’s age, ethnic background, gender, parental occupation and type of school – like state or independent. 

The level of air pollution influenced adolescents’ cognitive development in some but not all calculations, but these observations were not ‘reliable or conclusive’.   

‘As for adults, there is evidence that natural environments play an important role in children and adolescents’ cognitive development and mental health into adulthood,’ the team say in their research paper – but less is known about why this is. 




In the absence of green space, there may be artificial alternatives, as study author  Mikaël Maes at UCL explains. 

‘Forest bathing, for example – being immersed in the sights, sounds and smells of a forest – is a relaxation therapy that has been associated with physiological benefits, supporting the human immune function, reducing heart rate variability and salivary cortisol, and various psychological benefits,’ he said. 

‘However, the reasons why we experience these psychological benefits from woodland remain unknown.’  

Limitations of the study, published in Nature Sustainability, include the assumption that living or going to school near natural environments means more exposure to them, which may not always be the case.

Also, a considerable proportion of the participants (52.21 per cent) were in the group whose parents had a managerial or professional occupation, so adolescents in less favourable socio-economic groups may be underrepresented.       



WEEKLY ‘AWE WALKS’ CAN BOOST POSITIVE EMOTIONS AND REDUCES STRESS: 2020 STUDY

Going on a 15-minute ‘awe walk’ each week, where we stop to appreciate the world around us, can help boost positive emotions and reduce stress, a study shows.

The study authors, from the University of California, San Francisco, believe walking boosts our frame of mind even more if we make a note to soak up the beauty of all that is around us  

These ‘awe walks’, where we soak up nature, architecture and more, can boost healthy ‘pro-social’ emotions such as compassion and gratitude.

After analysing selfies taken during walks these walks over the course of eight weeks, the US experts found that ‘awe walks’ can make us smile more too. 

The team recruited 52 healthy older adults from the UCSF’s long-running Hilblom Healthy Aging Study programme. 




They asked each of these participants to take at least one 15-minute walk each week for eight weeks. 

Half of the participants in the study were asked to replicate the emotion of awe during their walks, by soaking up details of the world around them. The rest, in the ‘control group’, weren’t.  

After each walk, participants filled out brief surveys, detailing characteristics of the walk and the emotions they had experienced, including questions intended to ‘assess their experience of awe’. 

People in the ‘awe group’ reported increasing experience of awe on their walks as the study went on, the experts found.
