Why your brain needs a Garden


“There can be no other occupation like gardening in which, if you were to creep behind someone at their work, you would find them smiling.” – Mirabel Osler

Gardening awakens a primal urge that many of us have to connect with the earth. By putting your hands in the soil, you are able to physically unite with nature on an elemental level.
At the same time, gardening gets you outdoors in the fresh air and sunshine, helping your body produce much-needed vitamin D. It gets you moving, providing important exercise, and allows you to connect socially with others.
When you garden, you’re adding beauty to the landscape and habitat for birds, bees, frogs, worms, and so much more. Depending on what you garden, you can reap a harvest of fruits and vegetables to feed your family. You can also indirectly feed your brain for better mood and emotional health, and to satisfy your curiosity for knowledge.
In fact, learning is the fourth top reason why people say they garden — after to grow safe, healthy food, get exercise, and add beauty to their yard. Perhaps it’s no coincidence that people garden, in part, to stimulate their brains, as gardening has been shown to impact brain health considerably.

Spending time in a garden may help calm dementia patients
A new systematic review examined the impact of gardens and outdoor spaces on the mental and physical well-being of people with dementia. The research suggested that garden use, whether it be watering plants, walking through a garden or sitting in one, led to decreased levels of agitation or anxiety among the patients.
As for why the garden may help induce calm, Dr. Mark Stecker, chairman of neurosciences at Winthrop-University Hospital, who was not involved with the study, said:
“When your brain is impaired, you go back to your basic instincts. Many people have always enjoyed the outdoors. They may not have an explicit memory of that, but it’s an implicit memory. And they find it comforting to be outside.”
Interestingly, while spending time in a garden may help relieve some dementia symptoms, it may also help to reduce your risk of developing dementia in the first place. As reported by CNN:
“Two separate studies that followed people in their 60s and 70s for up to 16 years found, respectively, that those who gardened regularly had a 36 percent and 47 percent lower risk of dementia than non-gardeners, even when a range of other health factors were taken into account.
These findings are hardly definitive, but they suggest that the combination of physical and mental activity involved in gardening may have a positive influence on the mind.”

Gardening may make you happy via antidepressant microbes in the soil
According to a survey by Gardeners’ World magazine, 80 percent of gardeners reported being “happy” and satisfied with their lives, compared to 67 percent of non-gardeners. Perhaps it’s no coincidence that gardeners are happier.
Mycobacterium vaccae is a type of bacteria commonly found in soil, which people may ingest or inhale when they garden. Remarkably, this microbe has been found to “mirror the effect on neurons that drugs like Prozac provide.” It helps to stimulate serotonin production, helping to make you feel happier and more relaxed. No wonder so many people describe their garden as their “happy place.”
In one animal study, mice that ingested Mycobacterium vaccae had a demonstrated reduction in anxiety and improved learning. The researchers noted that natural exposure to microbes may be important for emotional health and behavior:
“Recent studies show that contact with tolerogenic microbes is important for the proper functioning of immunoregulatory circuits affecting behavior, emotionality and health […]
Collectively, our results suggest a beneficial effect of naturally delivered, live M. vaccae on anxiety-related behaviors… supporting a positive role for ambient microbes in the immunomodulation of animal behavior.”

Gardening helps you get grounded
There’s another way that gardening may help your mood and brain health, and that is grounding. The surface of the earth holds subtle health-boosting energy, and all you have to do to harness it is touch it. Walking barefoot on the earth transfers free electrons from the earth’s surface into your body that then spread throughout your tissues.
Grounding has been shown to relieve pain, reduce inflammation, improve sleep, and enhance your well-being.
Aside from increasing your sense of well-being and calm, keeping a garden can also improve your health by providing you with fresher, uncontaminated food; nutrient-dense food that is simply unavailable in your grocery store. It will also help you reduce your grocery bill. You don’t need vast amounts of space either.
Even apartment dwellers can create a well-stocked edible garden. You can use virtually every square foot of your space to grow food, including your lateral space. Hanging baskets are ideal for a wide variety of crops, such as strawberries, leafy greens, runner beans, pea shoots, tomatoes, and a variety of herbs. You can also grow sprouts like sunflower seeds and reap a harvest in 7-10 days.
And instead of flowers, window boxes can hold herbs, greens, radishes, scallions, bush beans, strawberries, chard, and chilies, for example. Just start small, and as you get the hang of it, add another container of something else. Before you know it, large portions of your meals could come straight from your own edible garden.
