Nature’s Healing Power

In his essay titled “Why We Need Gardens,” neurologist and author, Oliver Sacks wrote: “I cannot say exactly how nature exerts its calming and organizing effects on our brains, but I have seen in my patients the restorative and healing powers of nature and gardens, even for those who are deeply disabled neurologically. In many cases, gardens and nature are more powerful than any medication.”

Sacks, who died of a rare cancer in August of 2015, explained how he was introduced to the wonder of gardens as a child. And, as a physician in New York City, he took his patients to visit gardens whenever he could, believing that, just like music, gardens were vital “therapy” for people living with chronic neurological diseases. What is it about nature that is so calming and reinvigorating? he wondered, recounting the time a friend with Tourette’s syndrome became calm and tic-free on a hike in the desert. And how is it that patients with advanced dementia or Alzheimer’s disease can’t remember how to do everyday things like tie their shoes. “But put them in front of a flower bed with some seedlings, and they will know exactly what to do. I have never seen such a patient plant something upside down,” Sacks recalled.

“Clearly, nature calls to something very deep in us,” he continued, explaining his belief that nature affects us deeply spiritually and emotionally, as well as physically and neurologically. Had I read that essay before his death, I might have written Dr. Sacks a letter saying that, as a longtime gardener and lover of long walks in the woods, I couldn’t agree more with what he said in that lovely bit of writing. (Which can be found in the posthumously-published collection, Everything in Its Place: First Loves and Last Tales.) I’m not sure how I developed biophilia, an urge to connect with living things and nature, which I suppose progressed over time into hortophilia, the desire to interact with, manage and tend nature. But I’ve got both Big Time. And I know a whole lot of other gardeners who would say they do too.

Like Sacks, I can’t precisely tell you how nature works its mojo on people, but I do remember the first time I saw it happen. I was in college and working nights and weekends at a women’s shelter in North Minneapolis. The shelter had once been a convent for nuns, so the narrow, tile-floored room I used as an “office” had probably once been a nun’s bedroom. Our country doesn’t care about people who are struggling with mental illness, so the underfunded shelter paid me, and several other young women, about $8 an hour to look after dozens of women of all ages who had been diagnosed with schizophrenia and/or other serious mental health issues. Tucked away in their own narrow nunnery rooms upstairs, those women were also often dealing eating disorders, broken hearts, drug-and-alcohol addiction and abusive boyfriends who showed up to bang on the front door at all hours of the night.
