At The Heart Of My Evidence-Based Design Art
Art marketing experts and advisors have been telling me for years that I need to pick one art category and paint in it.
I tried to stay in one art category, figuring that my sales figures would eventually show me the right direction to take, but then I kept selling and selling in all of my categories.
Next, I thought I’d find my one big winning category when my art got viewed by art curators from around the world. If you look at my dorotheasandraart.com website’s first page and scroll down to the 2025 International Curations, you’ll laugh. I haven’t posted them all, but right now, I am in 44 different international art curations—and the art curators seem to like my art in all the different categories and styles I paint.
Thankfully, it was my evidence-based design knowledge and training that eventually helped me understand that I really do have one central item running through all of my art:
I discovered that—whether it’s a painting about sustainability, an evidence-based design floral impressionism, a water-inspired movement composition, or even an intense abstract—AT THE HEART of every single one of my paintings are elements of LOVE and CARE.
If the inside of my art could speak, it would say, “In this painting is love and caring about human health and happiness.”
The Happiness Factor by Dorothea Sandra, EDAC, 5’x8’
Using my Evidence-Based Design Certification (EDAC) training, the colors are bright, cheerful, and welcoming. Viewers can see through the stems, which scientific studies have shown to create safety in human minds. Flowers rooted in soil suggest a continuation of life, unlike cut flowers in a vase, which will soon die. The yellow sun, with its healthy-looking morning glow, gives many viewers the feeling that “survival” will be easy, which creates chemicals in the brain (like dopamine) that make humans feel happiness.
At the heart of this painting is a deep care for human health and happiness.
Happy Sustainable Memories by Dorothea Sandra, EDAC, 5’x8’
This next painting, Happy Sustainable Memories, is an entirely different style of art, but at its heart—like in The Happiness Factor—is a sincere caring about human health and happiness.
In evidence-based design and art, local scenery is often suggested as a composition. Instead of focusing on a snapshot of a local scene, I chose in this painting to take in an entire journey within a local area and represent it through art.
The composition was inspired by nature and a trip from Pasadena, California, along the super busy Foothill Freeway on my way into the desert area near Palm Springs. In this painting, I chose the cheerful colors of yellow, muted pink, and orange to represent the mountains. There is an abundance of sand in the desert, so I used Liquitex’s professional-level unbleached titanium/beige (with a touch of gold) color for the painting’s sky and background. In evidence-based design, you don’t need to portray everything realistically; for instance, creating a blue sky isn't always necessary.
For people/patients who know the area, this painting—in a fun and happy abstract/expressionism/impressionism style—reassures and comforts and recenters them by visually connecting them to their nature-filled and sustainable beautiful local scenery.
This next style of art—where many of my SMART CITY ART series abstract paintings were featured at the 2025 SRI Sustainability Research and Innovation International Congress in Chicago—radically differs from most of what I do.
At first, I was confused and thought, “Here I go again, taking off into yet another different direction.” It took some time, and again, I believe my evidence-based design training and certification helped me understand that underneath even these abstract paintings was this same caring and love for human health and happiness.
My SMART CITY ART abstract series is about caring about human health and happiness, not just individually, but collectively within communities.
Each painting has a smart city technology and sustainability message and a fun, happy, modern flow. In addition, embedded within each painting’s composition are smart city technology and sustainability symbols and iconography.
The paintings include scientifically acknowledged elements that lead to improved human health and happiness: nature-based solutions, blue areas, 15-minute walkability, financial equity, governance, and so much more.

Dynamic Cities Of The Future
Even within these dark and ominous paintings below, I realized that my love and care for human health and happiness was still the motivation at the bottom/heart/soul of all of my art. It was the energy behind everything that gave all of my paintings life.
In Middle Class Anger, I was concerned for human health and happiness as I watched the U.S. middle class lose economic stability and standing. In Chaos Enjoying Power, which was created about a month before the first “NO KINGS” rally even occurred, I was worried that power in chaotic hands would harm people and reduce human health and happiness.
Middle Class Anger
Chaos Enjoying Power
With my floral impressionism art featured on the 2025 cover of Healthcare Design magazine, all the way to this dark and sinister abstract art video below from Opulent Art in London, it seems as if my art is all over the place—but it isn’t.
The message is always the same: A care of human health and happiness is what my paintings are all about!
(In the video, starting around 2:30 minutes, Chaos Enjoy Power holds a premium place.)
Is Evidence-Based Design Legitimate Or Just Another For-Profit Buzzword?
Not long ago, I left a positive comment about a Dopamine Decor article at a homes and gardens magazine. Then, I got attacked by some troll saying that Dopamine Decor was just some new way for companies to make money off people.
Usually, I do not get involved with things like this, but I felt a strong urge to explain that a lot of Dopamine Decor and Evidence-based Design art is based on real, authentic, legitimate science and medical studies.
In my book, 100 Days Of Happy Happy Art, Evidence-Based Design, I wrote: “From the 1960s until today, serious researchers with very serious studies…from different countries…from different multidisciplinary fields have converged to create a new field called Evidence-based Design.”
Even the National Library of Medicine at NIH, the National Institutes of Health, has a definition of it. “Evidence-based design is scientific analysis methodology that emphasizes the use of data acquired in order to influence the design process in hospitals. It measures the physical and psychological effects of the built environment on its users.”
In cancer center lobby.
Today, Evidence-based Design isn’t just for hospitals. It’s for all of us. It is for many of the places humans go.
What is my role in all of this? A very small one—but I think an important one. Today, my art hangs in hospitals, businesses, organizations, and homes. Using my talent and evidence-based design training and certification, I very deliberately and very strategically create HAPPY HAPPY HAPPY art for built environments.
Here’s one of my paintings as it hangs in the lobby of a cancer wing in one of the U.S. hospitals.
The person in charge of art placement at the hospital apologized for its location on a side wall in the lobby.
She thought I might be offended by not having it centered over the main mantlepiece in the waiting area. I wasn’t offended at all. In fact, people come face-to-face with it as they enter the blood draw area. Putting all artist ego aside—and focusing on patient/people needs—I thought it was perfectly located.
Too Beautiful For Words, 36”x36”
Too Beautiful For Words is a super cheerful “distraction” piece. Getting cancer and getting treated for it is often horrific, and at times, it can make patients and others feel as if they are about to lose their minds or are living through some “other world” reality. I thought adding an upbeat quirkiness to the art would help—in a positive way—identify with the circumstances and would also help release some dopamine (happiness brain chemicals).
Patients, their families, and the staff kept telling me—all the time—how happy this painting made them feel, so I decided to donate two other paintings that evolved over the years into a new evidence-based design series called Symphonies of Love.
Both paintings below are placed today in cancer patient examination rooms. People in this community with cancer or with a loved one with cancer continue to tell me how much they appreciate the heart shape, which simply but beautifully communicates to patients that they are loved.
One of these 61” x 78” evidence-based design heart paintings recently got featured on one of the world’s most prominent online art gallery websites. I was listed as one of sixty-one American artists to follow.

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.
Healing Abundance by Dorothea Sandra, EDAC
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.
Why Did I Become Evidence-Based Design Certified?
A couple of years ago, I was on a very popular—and seemingly legitimate—New York City art website that was promoting art for health and healing.
Get this—misshapen and horrifically disfigured images; spread open naked human legs and rolls of unhealthy body fat; abstracts of daggers and dripping blood—all amazing works in their categories—just nothing I would consider appropriate for the elimination of stress or the recovery of human health.
This set me on a course for knowledge. I wanted to discover if I could actually learn to design/create with your health and healing in mind. I found The Center For Health Design with its excellent EDAC (Evidence-based Design) courses and certification. Imagine thousands of doctors, hospital administrators, health facility architects, hospital room designers, and many more professionals worldwide basing their creative/artistic decisions and designs on actual medical studies.
Instead of some untrained art critic or consultant setting the standards for art, health, and healing, I now had real medical professionals to learn from and follow. The EDAC exam was the most challenging test I ever took (and I’m a university graduate with high grades), but the knowledge I gained—which I now incorporate into my designs—was absolutely worth all the hard work.
It’s amazing how many people who buy my evidence-based designs tell me how this “evidence-based” art actually shifts their moods and creates positive and uplifting feelings/states of mind.
Here are four examples of what should never be promoted as evidence-based art for health and healing. Two of the pieces sold within minutes to a collector. They had merit, just not as evidence-based design art.
The first painting is titled Anguish and is part of a series I created about child abuse. This painting artistically reflects the mental and emotional suffering that children experience when they are not nurtured in healthy ways.
The second work, Killed Opportunities, shows how barren and tragic a child’s life becomes as opportunities for health and happiness are killed.
The third painting, Death By Power, reflects negative power winning. The face of a hideous creature looking at the viewer (top center) and a hand with the middle finger raised up (lower center) are perceptible.
In February 2025, I sold The Tempest, the fourth painting, again to a collector.
All four paintings have merit as works of abstract art. The art itself, however, does not de-stress or promote health and healing. In fact, it does the opposite.
Can you imagine the added stress and trauma of looking at any one of these paintings while recovering in a hospital bed? Before training to become evidence-based design certified, I wondered why influential people in the art world were calling paintings like this art for health and art for healing. It just didn’t make any sense to me.
Here are more beautiful paintings that would not be considered 100% appropriate evidence-based designs. Some I sold, some are for sale through a Paris, France international gallery, my website, Galleri Soho in Sweden, and more.
When I create evidence-based design art, I use design suggestions and strategies based on credible scientific and medical research. I get my information from a variety of sources, but I enjoy and value the trainings (which are required for EDAC recertification) at the Center For Health Design and their journals and repository information.
There’s a difference between pretty art that makes us feel happy and art that triggers our brains to feel happy based on medical and scientific research. Evidence-based design is that kind of art.
Is Evidence-Based Design Totally New?
Is Evidence-Design Totally New?
If you asked the 6th BCE Greeks of Epidaurus, they might take you to one of the most celebrated healing centers of the classical world—the Asclepieion hospital. In their hospital, patient rooms faced eastward. Why? It is believed the rooms were intuitively designed and placed toward the sun to promote healing.
Many centuries later, many movements from different countries came together in the 1970s to create a new field called evidence-based design.
Who are the people whose forces created this new discipline? Doctors, Scientists, Architects, Interior Designers, Psychologists, Sociologists, Anthropologists, and many others.
The Healing Window by Dorothea Sandra, EDAC, 36”x48”
This artist’s journey into Evidence-Based Design
Photo from the back of McLaren Northern Hospital, Petoskey, Michigan
I am known by many titles in the art world: Artist Of Happiness; a modernizer of traditional woodland compositions; a Great Lakes artist; a 21st-century experimental artist; creator of the evidence-based design collection, Symphonies Of Love; creator of the Smart City Art Collection; and more.
At the beginning of my evidence-based design artistic journey, I chose to create a painting depicting a view from a hospital room. The background of The Healing Window features Little Traverse Bay, as seen from the back parking lot of McLaren Northern Hospital in Petoskey, Michigan.
While composing this painting, I imagined myself in one of the patient rooms at McLaren Northern, looking out the window.
I also imagined myself in a patient room or in a healthcare lobby or a waiting area.
Artists always have lots of choices to make. Early in my evidence-based design floral art career, I chose creating happiness (triggering dopamine) over painting realism. My reason? I figured I would have more power to create happiness if I had more artistic power of the flowers. Not only did realism limit my ability to create happiness (dopamine), but according to medical and scientific research, traditional still-life wasn’t an art category most favored within evidence-based design.
So, is evidence-based design totally new? Yes and no. The flowers in this artwork are modern, cheerful, uplifting, and based on current evidence-based design best practices. However, I also wanted to pay homage to the accomplishments of those who came before us by incorporating elements that, especially in the design texture of the vases, evoke a rough, ancient Greek Asclepieion aesthetic.
Inside Evidence-Based Design Art
I do not have the expertise of a neuroscientist or medical researcher or practitioner, but I do LOVE to study their evidence-based design results and find ways to experiment with them in art.
In Symphonies Of Love Number 11 my goal was to create a beautiful work of art without much impact.
To create the beauty, I chose the shape of a heart because I wanted a very clear, strong message that instantly communicated, “You are loved.” I find too much evidence-based design art today a little too wispy and without form. Sometimes people, and especially children, need a clear, up-in-your-face message, especially one of love.
Can you imagine a child in a patient bed or waiting area? Fear, worry, doubt can be big factors within a healthcare setting. I think an image of a heart outperforms a typical biophilic design when it comes to encouraging feelings of love, safety, and care.
Also for this painting, I chose to blend the inner area of each flower mostly with each flower’s petal color. What this does is create beauty without impact/stress, something super valuable within many healthcare environment locations. Some people are at the outer limits of their emotions in this setting, so creating beautiful art that does not stress is often welcome and greatly appreciated.
Take a look inside my book, 100 Days Of Happy Happy Art, Evidence-Based Design.
There’s even a chapter on neuroscience and art.
Experimenting With Art And Health
I’m an artist and innovator in the field of art and health, so I like to experiment a lot.
Recently ARTPLACER.com, an art placement company I really enjoy, added patient rooms to their excellent selection of mockup photos. Today my happy evidence-based design art hangs in so many different physical settings, but I have always told people I never considered it a good fit for the inside of a hospital patient’s room.
With ARTPLACER’S new mockup photos, here was my chance to really experiment within the inside of patient rooms, so I did.
When I create evidence-based design art, I think back to when I needed two major surgeries in different parts of my body in less than 30 days. Through this experience I realized there were so many different stages involved—such as the in-hospital pre-operation stage, the in-hospital post-operation stage, and the at-home longterm recovery stage. I also realized how my needs were different during each stage.
Right after surgery, while in my patient room, I felt that my entire body had been seriously assaulted and traumatized—and it had. The hospital, the staff, and my two doctors were all excellent, but that’s just what happens when a human body needs major surgical operations.
While inside my patient room, what I needed most was a total relief from any additional stimulation or trauma. Most of my evidence-based art is strategically and deliberately designed to not stress, but it is also designed to stimulate.
The trick—or I should say the skill—as an evidence-based design patient room artist is to create a work of art that is lovely according to the evidence-based design guidelines but is also one that does not cause too much brain stimulation. The art should be lovely without impact.
Placing different pieces of my art in ARTPLACER’S new hospital rooms, I was able to do some experimenting and here are some things I discovered.
Very much to my surprise, some of my florals did very well, even in a darker patient room. They were lovely and uplifting and fit comfortably in this room without creating too much stimulation to the brain.
I was even more surprised to see that even my bolder evidence-based design florals succeeded. They clearly delivered happiness and cheer without causing any stress or trauma.
Here are some of my other evidence-based design paintings that I thought might just work inside a patient room. I have always felt that my ideal hospital patient room should have carefully selected works of real art on the wall. Bland, boring, stereotypical designs actually frighten me. It’s as if this art makes a kind of heart monitor flatline sound. For me, art is hyper visual but it’s also always full of music and sound.
