Different Types Of Evidence-Based Design
There’s Evidence-based Design, and then there’s NOT Evidence-based Design.
Here are a few evidence-based design art guidelines. Many of these guidelines come from “A Guide to Evidence-based Art” from The Center For Health Design, research by Ulrich and Gilpin, a case study on best practices in evidence-based design by the Mays Clinic at the MD Anderson Cancer Center, and so much more.
Landscapes
They can be regional, generic, or seasonal. They should have visual depth or open foreground. Trees should have a broad canopy. Savannah and park-like landscapes are preferred by many. Vegetation should be lush. Empty park benches and sunsets should be avoided. The empty park bench might remind someone of loss and loneliness. A sunset might represent the end of life.
Florals
Florals should include familiar shapes of plants and flowers. They should appear healthy and fresh, and flower colors should be vibrant. Gardens and bouquet styles are acceptable. Flowers in vases should be used sparingly and only for variety.
Taking scientific or medical study results and turning them into artistic creations is not the easiest thing to do. There are no step-by-step guides to follow, and the rules need to be there, but sometimes they need a little bending.
The painting above, Healing Flowers, spent time on exhibit in a museum and then in a gallery. It recently sold, in 2025, to an art collector in Fort Worth, Texas. Also, in Jan/Feb 2025, it was featured on the cover of Healthcare Design Magazine. In addition, in 2024, I was also asked to show it in another issue of Healthcare Design Magazine issue. On one international art gallery website, this painting received thousands of views.
While creating it, I tried to adhere to the evidence-based landscape design guidelines for healthy outcomes. By following the rules, I figured I could trigger the brain to create dopamine, which would produce in its viewers feelings of happiness.
If you look closely, you can see through the stems, which gives viewers visual depth. According to the research, seeing through the stems helps humans feel safe. It takes us back to our days of hunting on the Savannah, where dangerous animals could hide in thick grass and then attack us. While the stems were thin, I ensured the flowers appeared lush and abundant. Again, this would suggest an abundance of food.

Using the same evidence-based design guidelines, Healing Abundance also sold in early 2025. It was sold from a gallery in Paris, France, and shipped to a company in Hong Kong with television channels in Hong Kong, mainland China, Macau, and other Chinese-speaking areas. The soil and stems are there, but I wanted to add lush vegetation through the flowers.
Years ago, when I was living in Asia, a good friend who was also a medical doctor ended up in the hospital. I went to visit her with a bouquet of cut flowers in hand. After she got out of the hospital, she told me that a bouquet of flowers was not the best gift. A potted plant would have been more appropriate. When I asked why, she explained that cut flowers will soon die, while a plant in soil continues to live on.
Most everything I do in the creation of an evidence-based design painting is for the health and happiness of viewers.
Did You Know This About Our Brains And Art?
Did you know a growing body of research shows conclusively that our physical environments (rooms, buildings, walls, etc.) actually have an impact on our quality of life?

Evidence-based design has been defined as the process of basing design decisions about the built environment on credible research to achieve the best possible outcomes.
When inside built environments our brains get triggered by all kinds of things like color, lighting, texture, and especially art. In one study done on hospital waiting areas, physical and ambient properties influenced patient experiences. Areas associated with higher physical attractiveness reduced anxiety, were perceived to provide better quality of care, and were perceived to have shorter waiting times.
“Similarly, a waiting area with a nouveau (non-traditional) style was associated with lower self-reported stress and higher patient satisfaction than a traditional style.” (Improving the Patient Experience, California Healthcare Foundation)
Fun Fun Everywhere is a playful evidence-based design work of art. It’s a fun painting designed for attractiveness in a nouveau/non-traditional style.
Happy Together With Friends by Dorothea Sandra, EDAC
As I am creating this style of playful evidence-based art, there’s always the challenge of balance. One goal is to trigger the brain to create lots of feelings of fun and happiness without causing any stress. Another goal is to achieve high “distraction” levels of interest, again, without causing stress by overwhelming the viewer with too many details.
Especially when people are troubled or in pain, research studies show that happy art distractions will very positively impact the quality of human life.
For Happy Together With Friends, I was going for the moods of playfulness, happiness, and fun. I also wanted to add in a dash of ironic quirkiness with the hope of making someone—who just didn’t feel good or well—crack a smile.
I have a painting, similar to this one, in the cancer wing of a hospital. When coming out of the blood draw area and on the way to the infusion center, there it is.
Cancer patients, family members, and staff tell me all the time just how much they enjoy that painting. I’ve always suspected it’s the ironic quirkiness built into the painting’s many layers that triggers the brain to create happy emotions, especially at solemn times like this.
These paintings were created—not for their realism or beauty—but to trigger the brain to create the feelings of fun, happiness, and joy.

There’s even a chapter on neuroscience and art.
