It’s in the Dirt! Bacteria in soil may make us happier, smarter

Many people, including me, talk about the restorative benefits of gardening (see last Tuesday’s post, for example) and the reasons why it makes us feel good. Just being in nature is already therapeutic, but actively connecting with nature through gardening is value-added. And why is that? All sorts of reasons have been posited: It’s a meditative practice; it’s gentle exercise; it’s fun; it allows us to be nurturing and to connect with life on a fundamental level.

And some recent research has added another missing piece to the puzzle: It’s in the dirt. Or to be a little more specific, a strain of bacterium in soil, Mycobacterium vaccae, has been found to trigger the release of seratonin, which in turn elevates mood and decreases anxiety. And on top of that, this little bacterium has been found to improve cognitive function and possibly even treat cancer and other diseases. Which means that contact with soil, through gardening or other means (see Elio, above), is beneficial. How did this discovery come about?

Speaking of allotment gardens (see our 1/13 post about Charlie Hopkinson’s photography of allotment gardens), here’s an interesting study:

30 allotment gardeners were assigned to do a stressful task (not related to gardening). Immediately after, half of the gardeners worked in their own allotment plot and half read indoors, both for 30 minutes. With both groups, cortisol (a stress indicator) and self-reported stress levels went down, but they decreased significantly more in the group that gardened. I think I’m going to build me a greenhouse…

And here’s a moving blog by someone who struggles with depression and finds solace in her allotment garden. The blog is Allotment Therapy: A personal view of Ecotherapy, and the post is “The Wisdom of Plants.”

Stay tuned for another article on this topic, coming very soon!

Full abstract (link to the Journal of Health Psychology website to access the abstract and to buy the article): Stress-relieving effects of gardening were hypothesized and tested in a field experiment. Thirty allotment gardeners performed a stressful Stroop task and were then randomly assigned to 30 minutes of outdoor gardening or indoor reading on their own allotment plot. Salivary cortisol levels and self-reported mood were repeatedly measured. Gardening and reading each led to decreases in cortisol during the recovery period, but decreases were significantly stronger in the gardening group. Positive mood was fully restored after gardening, but further deteriorated during reading. These findings provide the first experimental evidence that gardening can promote relief from acute stress.

Color in the winter garden: Beyond trees and shrubs

Saturday, January 8th, 2011

Blue chair. Photo by Naomi SachsWinter in the garden consists mostly of earth-toned hues – browns, tans, buffs, greys – and these do have their subtle charms. But around January, I start to pine for color.

Yes, trees and shrubs can fulfill that need – evergreens, of course, and also trees like Hawthorns, with their bright red berries that persist until spring, and shrubs like red- and yellow-twig dogwood with bark that is striking against a backdrop of snow.

But don’t feel limited to plants. I have one very durable blue metal chair that stays out all winter long, and it brings me cheer. I’ve seen brightly painted garden walls and fences, furniture, pots, sculpture, and all sorts of other non-plant-material garden elements that stand out and provide color between November and April. What about you? What’s “blooming” in your winter garden? Now is the time to gaze out the window and think about where you might want those bright sparks that bring joy and hope on a cold, grey winter’s day.

To Rake or Not to Rake? Good Question!

Well, it’s November, and if your yard looks anything like mine, the leaves are starting to pile up. So, do you rake them, do you let them be, does a landscaping crew come with their leaf-blowers and haul them away? This year, I’ve seen several articles suggesting that gardeners not rake. Leaves make excellent mulch and they attract and protect all kinds of beneficial wildlife. And they’re free! Personally, as I live under two giant white oak trees, I feel the need to rake some (in fact, in Ellen Sousa’s recent blog post “Leave those leaves!” in which she advocates for not raking, she makes an exception for oak leaves). Carole Brown of Ecosystem Gardening and co-founder of Beautiful Wildlife Garden posted a good “to rake or not to rake” discussion that touches on many reasons why people do and don’t (and even should and shouldn’t) rake: “I am the Lorax, I Speak for the Leaves.”

A recent article in Fine Gardening (“Improve Your Soil by Raking Less“) provides lots of ideas about how to turn your leaves into gold. For leaves on the lawn, you can run them over with a mulching mower. Rather than smothering it, the organic matter and nutrients in the leaves will improve turf quality. You can rake leaves into garden beds to create mulch that both protects and feeds. You can even build planting beds with leaves. I highly recommend all three of the above-mentioned online articles for information and inspiration.

If you do choose to rake, think of it as an exercise opportunity rather than a burdensome chore. Who needs the gym when you’ve got leaves! Raking is one of many gardening activities that, if done for 30 minutes a day, can increase metabolic rate, reduce blood pressure, improve cholesterol levels, tone muscles, improve flexibility, and even improve cardiovascular fitness – enough to reduce the risk of heart disease and type-2 diabetes. Raking burns approximately 375 calories per hour (for comparison, jogging burns about 430 calories per hour).

Many horticultural therapy programs include raking, both for the physical and psychological benefits. It’s something most of us have done at some point in our lives, and it often brings back fond memories (mine are a lot like these pictures, jumping into and playing in big piles of leaves).

So if you’ve got leaves, the decision is yours what to do with them. But whether you rake them up, leave them be (sorry, couldn’t resist) or something in between, try to think of them as yet another gift from the garden.

Many thanks to Allison Vallin and her lovely blog, A Tasteful Garden, for the photos.

Garden Designers Roundtable: Thoughts and Evidence on Therapy and Healing in the Garden

Tuesday, October 26th, 2010

I go to nature to be soothed and healed, and to have my senses put in order.

This blog post comes courtesy of the Garden Designers Roundtable, who invited me to be their first-ever guest blogger. I’m honored and excited to be participating in today’s roundtable discussion, the theme of which is “Therapy and healing in the garden.” All photos are by Naomi Sachs.

Some Thoughts and Evidence on Therapy and Healing in the Garden

The idea that gardens and landscapes foster good health seems like a no-brainer, especially to gardeners and garden/landscape designers/architects. It’s like telling Newton that apples really do fall down. Sadly, though I’m preaching to the choir here today, many people still haven’t grasped this concept, and we can find all too many examples of landscapes that are anything but healing (picture, if you will, a parking lot at the mall…). At the Therapeutic Landscape Network, we focus a lot of our attention on the design of hospitals and other healthcare environments because – oddly enough – they tend to be so far behind as places that facilitate health and well-being on a holistic level. We’re getting there, but we still have a long way to go.

For today, since a big part of the TLN’s mission is to connect designers and health and human service providers with the research they need to design beautiful, nurturing, successfully restorative spaces, I thought I’d highlight some of the evidence that we’ve blogged about over the years. In this case, research that “proves” that being in and interacting with nature is, indeed, restorative for body and soul. This research is important because it’s positive ammunition. It’s what makes CEOs, and policy makers, and grant funders and our clients sit up and take notice (and change the laws and sign the checks!). I’ve provided a one-sentence summary of the research, with the title of each related blog post that you can link to for more information and full citations.

But first, for background, the seminal ‘View Through a Window’ study:
In 1984, Roger Ulrich studied two sets of patients, both in the same hospital, both recovering from the same surgery. The key difference: One group’s view from their window was of nature – grass, trees and sky; the other’s was of a brick wall. Ulrich found that the patients with the nature view complained less, required less pain medication, and made a faster recovery. Here, finally, was empirical proof of the salutary benefits of nature. Ulrich’s paper, published in the journal Science, got the attention of the medical community and legitimized the field of evidence-based design. Evidence-based design being the use of quantitative, and sometimes qualitative, research to design environments that facilitate health and improve outcomes. Since then, hundreds of studies have been published. Some, like those cited below, continue to demonstrate that contact with nature is good for people; some explore how people benefit, and what conditions are best for specific groups, needs, and situations (e.g., children; seniors with dementia; gardens for people who are immuno-compromised).

The evidence since ‘View Through a Window.’ A few good examples:

Trees, greenery, and other vegetation make neighborhoods safer and more desirable. They even play a role in boosting students’ grades and reducing the risk of domestic violence.
See “Healing the Neighborhood: The Power of Gardens.”

Plants in an office setting improve worker satisfaction, creativity, and productivity.
See “I Demand Satisfaction! The Role of Nature in Job Satisfaction.”

As little as 10 minutes spent outside improves attention in children with ADHD; neighborhoods with more green space improve body mass index of children and youth.

Gardening improves health and happiness, including reducing heart rate and blood pressure.
See “Horticultural Therapy in the Wall Street Journal.” Horticultural Therapy is “a professional practice that uses the cultivation of plants and gardening activities to improve the mental and physical health of its participants,” (definition courtesy of the Horticultural Therapy Institute). Hort therapists often work with occupational and physical therapists in a garden setting; gardens that are designed specifically for this kind of therapy are called rehabilitation gardens. For more information, see the horticultural therapy page on our website and for a really inspiring post about the power of horticultural therapy, see A Life Worth Living: The Garden as Healer.

Exposure to nature makes people more altruistic and generous.
It’s true, Nature Makes Us Nicer!
