Last September, over 200 participants took part in a unique forum in Vancouver to discuss nature and health – more specifically, the impact of spending time in nature on health, and the contribution of parks and protected areas to healthy communities. The forum sought to share knowledge, foster linkages between diverse sectors, and to identify best practices, strategies, and tools.

One of the things discussed by presenters and attendees was how people intuitively know that being in nature, simply put, makes them feel good. Whether getting a dose of ‘Vitamin Green’ helps to relieve stress, lift the spirit, or provide a bit of perspective on life, getting out into nature seems to contribute to enhanced wellbeing. While everyone intuitively understands this, our reductionist North American tendencies have had us questioning how and in what ways nature has this effect on health for the past decade or so. Well, good news for those of you scientific folk out there (you know who you are!) – the quantitative evidence supports a nature-health link. Our intuitive selves have been right all along! As discussed by keynote speaker Dr. Frances Kuo, research has linked healthy urban ecosystems to stronger, safer neighbourhoods, lower crime, reduced AD/HD symptoms, and reduced aggression, with benefits still being found even when income and other factors that could explain a nature-health link are taken into account. Additional quantitative evidence exists at the physiological level as well, with benefits having been measured objectively through such indicators as blood pressure and immune system functioning. For a comprehensive review of the literature, check out this National Recreation and Park Association report written by Dr. Kuo.

So now the evidence is there to prove what we kinda knew all along. What’s next? Well, at an individual level, we can all get outside more. If you’re like the bulk of urbanites, you may not be close to mountains, lakes, and forests (although a shocking number of us here in B.C. actually are – not to rub it in, Toronto). Forum presenters actually addressed this, and made it clear that nature can be found anywhere – a nearby park or stream by your house, a patch of trees outside your work – and even the smallest exposure to nature has been found to be beneficial.  In addition, urban planners and health professionals have been starting to act based on this ever-growing body of evidence. For example, some physicians are now prescribing time in nature to their patients.

Getting past the urban/nature divide may take some work ... but it can be done
