Another fine book I'd like to recommend is Emma Kennedy's The Wild Remedy: How Nature Mends Us. In this beautiful diary enriched by nature drawings, paintings, and photographs, Emma recounts the ways that immersion in nature helps her to live with chronic depression, records her encounters with the flora and fauna of the Cambridge fens, and discusses the science underpinning her thesis: that being in nature produces physical and neurological change in the human body.
"Of course, I am not the first to have noticed the consolation of walking outdoors. Literature is peppered with references to striding in the countryside as a means of easing melancholy, inspiring creative thought and hastening recovering. The 19th-century Danish philosopher, poet and theologian, Søren Kierkegaard, exalted a daily stroll: 'Every day I walk myself into a state of well-being away from every illness; I have walked myself into my best thoughts, and I know of no thought so burdensome that one cannot walk away from it.' Elizabeth von Arnim wrote one of my favourite novels, The Enchanted April, in the 1920s, and her feelings on walking through the countryside echo my own: 'If you go to a place on anything but your own two feet you are taken there too fast, and miss a thousand delicate joys that were waiting for you by the wayside.' "
A few pages later she notes:
"Joint research from the University of Madrid and the Norwegian University of Life Sciences published in 2007 showed that simply seeing natural landscapes can speed up recovery from stress or mental fatigue, and hasten recovery from illness. Studies published in 2017 from the University of Exeter have demonstrated that the presence of vegetation in an urban landscape diminishes levels of depression, anxiety, and perceived stress levels in city dwellers, and the same raft of work showed that time spent outdoors alleviates low mood....
"Research aimed at understanding the Shrinrin-yoku phenomenon [the practice of 'forest bathing' in Japan] has show that walking in green space has a direct positive effect on several systems in our bodies. Blood pressure decreases, levels of the stress hormone cortisol drop, anxiety is alleviated and pulse rates diminish in subjects who have spent time in nature and particularly among trees. Levels of activity in the sympathetic nervous system, responsible for our fight or flight response to stress, drop away and the activity of a particular kind of white blood cell called natural killer (NK) cells, which can destroy virally infected and certain cancerous cells, increases when humans spend time in a woodland environment."
The science is still progressing, Emma writes, "but I'm fascinated by the idea that the balance of the chemistry of my brain, and my hormonal and nervous systems, are changing as I linger among trees and plants, and that this can impact the tone of my thoughts and my mental health. I have felt the curative effects of my surroundings as I walk in a wild place numerous times, and it is reassuring to know that there is something I can do to help myself on dark days."
"At no point would I suggest standard treatments for this condition can be replaced by dawdling near a dog rose," she adds; "I rely on antidepressants and talking cures to prevent my illness from becoming overwhelming, but depression varies in its grip on my mind, depending on the season and on daily stress levels. I have found that the basal level of respite provided by antidepressants and therapy is sometimes insufficient to prevent my thoughts falling down a well. It is at these times that I find walking among hazels and hawthornes can help to dial down cortisol levels and cause the shift in neurotransmitters that I need to fend off the black dog."
(Sorry, Tilly. She doesn't mean you, dear.)
Although my own health problems are physical rather than neurological, the two are inextricably linked, of course, and much of this gentle, artful, informative book spoke to me on a personal level. I, too, find healing among the trees. Thus I recommend Wild Remedy to all who travel through illness of one kind or another...and since, sooner or later, that is all of us, this book is for every reader who loves, or might come to love, the natural world.
