Get outside for some fresh air, it’ll work wonders!
I am sure you, just like me, have at one point or another been told to get outdoors to blow the cobwebs away - but why? The idea for this blog post came about after listening to the Radio 4 Forest 404 podcast on the train last weekend (listen to it! its a super cool eco-thriller with the soundtrack by Bonobo and supporting science snippets! whats not to love!). Whilst listening to a supporting science snippet from Alex Smalley from the regarding the outdoors and wellbeing, I realised I’d camped more weekends in the last month than slept in my own bed. Plus I’m imminently off on holiday for another 8 days of camping! I am fairly certain that despite it’s amazingness my thermarest isn’t as luxuriously comfortable as my double bed. So, there must be another draw to being out in nature.
Reason 1: Our hard-wired love for nature
We humans have something deep within our psyche pushing us towards tree-hugging… “biophilia”; we love (philia) connecting with living (bio) things. The “biophilia hypothesis” first introduced and popularised by Edward O. Wilson in 1984 suggested that this connection with nature is why we enjoy looking at baby animals, have pets, decorate our homes with house plants and spend time outdoors.
Have we lost touch?
However, as we have become more developed, in turn spending more time indoors and behind screens we have also become more disconnected with nature. A National Trust report coins that we as a nation, especially our children, are exhibiting symptoms of the modern phenomenon ‘Nature Deficit Disorder, children watch more than 17 hours of television per week, but only play outside for 2.5 hours on average. The scary part of the report was the fact that Britain’s 11-15 year olds spend about half their waking lives in front of a screen, 7.5 hours a day, equating to 53 hours a week, an increase of 40% in a decade. WOW.
Is it all bad news?
Re-establishing connection with living things has become an important area in the field of conservation. Fuelled by many factors, biophilia seems to be on the rise. In the UK, the houseplant industry (£2.2 billion) is now worth more than the UK music industry (£2 billion). Despite the day to day lack of outdoor play for children, people are visiting nature more too, Natural England found visits at least once a week have increased from 54% in 2010 to 62% in 2018, and in England’s most deprived areas this has gone from 38% to 51%. Natural beauty can elicit feelings of awe, such as looking at the view from a mountain top, restoring mental fatigue.
Driven by nationwide and global pressures, on 1st May 2019 the UK government announced a climate emergency. Fingers crossed that the growing (pardon the pun) resurgence of caring for the planet continues! I believe that when I go outside on a walk or camping that due to my innate human biophilia (it sounds like some sort of terrible affliction!!) my body and brain feels better - but it gets even more sciencey than just the feeling of joy.
Reason 2: The magic of ‘Green Health’
Being surrounded by green living things is good for you; boosting ‘green health’. In Japan, forest bathing, called “Shinrinyoku” is a short leisurely visit to a forest, regarded as being similar to natural aromatherapy and is common practice among its population. Certain conifer trees release monoterpenes, a molecule that may reduce stress and stimulate digestion and immune function. Trees also release phytoncides, organic compounds with antibacterial properties that could also be health boosting for up to a month after a 30 minute trip to the forest. So forest bathing is good, but you probably can’t replicate the benefits sniffing on a ‘Little Tree' Forest Fresh car air freshener.
Reason 3: The mystery of ‘Blue Health’
It’s not only ‘green health’ that has attracted attention, but ‘blue health’ is becoming more in the spotlight. I have found being around or on the water is really relaxing. Scuba diving feels like a turbo fuelled shot of chillaxation and rowing brings me really close to our ‘Blue Mother Nature’. Down in Devon at the European Centre for Environment and Human Health (University of Exeter) the BlueHealth project has found that being near aquatic environments is good for your health - but they’re not sure why. There’s so many possibilities. Some research has shown that moving bodies of water give off negative ions which could reduce depression. There really is no conclusive answer - further research into the importance of blue health is needed.
Why is it important to understand blue and green health?
The science surrounding why is complex, confusing and has many factors to draw out and understand. Especially in the changing planet we live in. Which makes me wonder, with future sea level rise, will living near the coast remain as relaxing as it is now? I’m not sure, but I imagine if you’re house may be washed away by erosion it might not be so relaxing to live there all the time. Do cloudy days have as much benefit as sunny days? Again, the intertwined effects of sunlight must be important.
Answering these questions (and many more) surrounding green and blue health is important. Lack of accessibility to green and blue space remains a problem. Living in Bristol I can quite easily access one of the many city parks, but without a car escaping to National Parks isn’t easy (or cheap!). Building up knowledge surrounding green and blue health will enable urban designers to implement green and blue space effectively, improving physical and psychological health.
Urban green space provides residents with psychological relaxation, stress alleviation, it can stimulate social cohesion, support physical activity, and reduces exposure to air pollutants, noise and excessive heat. There are profound beneficial effects such as improved mental health, reduced risks of cardiovascular disease, obesity, diabetes and death, and improved pregnancy outcomes. Most recently, researchers in Barcelona found that regenerating a a Blue space, a riverside park along the Besòs river, enabled 6,000 adults use the park each day, plus suggest that visitors increased physical activity could prevent up to seven deaths and save 23 million euros in public health spending each year.
My final thought…
I’m happy to say I have more than 14 houseplants in my bedroom, I embrace my biophilia. I probably have an addiction to sniffing tree pheromones and ocean air (I don’t think I am alone in this). But I know it makes me feel good, even ‘the science’ says so. Join me, I reckon it’s fairly contagious - its good for you too!
Get outside for some fresh air, it’ll work wonders!!!
