The Forgotten Medicine: Why Sunlight—and Outdoor Living—Still Heals Us
They asked him how he wanted to spend the time he had left. What he said surprised everyone:
“I want to go outside.”
Just a quiet wish from a boy who was told he had two days to live.
Dr. Roger Seheult, a board-certified pulmonary and critical care physician, recounted the story in a recent interview that has stirred hearts and opened eyes around the world. The boy—diagnosed with lymphoblastic leukemia—had undergone chemotherapy and, as a side effect, developed a flesh-eating fungal infection in his lungs. His left lung was surgically removed. Then the infection spread to the right lung. With no options left, his doctors gave him two days to live.
So what did he want?
To go outside.
Hospital staff, hearts broken, pulled every string they could. They rolled his bed out into the open air. He lay there—under the sun, breathing through a BiPAP machine, wrapped in the hope of the light. He hadn’t seen daylight in six weeks. They also used a light therapy device called a Firefly. But nothing else changed. No new medications. No new protocol.
Except… he began to recover.
His white blood cell count dropped. His oxygen levels improved. By day five, he was off the BiPAP and breathing through a simple nasal cannula. A follow-up CT scan showed the infection had receded by 60 to 70%. Eventually, he went home.
Dr. Seheult said: “No change in medication. No change in treatment. They changed nothing. The only thing they did… was take him outside.”
Sunlight Isn’t Decoration—It’s a Design Feature
Light isn’t just a backdrop to life—it’s a signal our bodies understand. It helps us reconnect with the natural design that keeps us well. Sunlight regulates us. It speaks to our cells, our rhythms, our strength, and stability. Each sunrise offers a reset. It gently calls the body back to balance. Our sleep, immunity, lungs, bones, and even emotions respond to the light that fills each new morning.
We Were Meant to Live Outdoors
For most of human history, people rose with the sun and rested when it set. They worked and played beneath its rays. Today, Americans and Brits spend about 92 to 93% of their lives indoors. We live in what Dr. Seheult calls a culture of “dark days and bright nights.” And it’s making us sick.
Modern lighting, with its narrow blue-heavy spectrum, lacks the full bandwidth of sunlight—especially infrared light, which our bodies crave. And at night, screens confuse our brains by mimicking daylight, disrupting sleep, halting melatonin production, and setting off a cascade of physiological imbalance.
What’s more, indoor air lacks the freshness, the biological cues, and even the beneficial particles that trees and soil release outdoors. Green spaces and tree-covered neighborhoods correlate with lower rates of stroke, hypertension, depression, and even inflammation markers like C-reactive protein. And yes, infrared light still reaches you on cloudy days. Being outside—even in overcast weather—is still significantly better than being indoors.
The Timber Frame Invitation: A Healthier Lifestyle, Built-In
This is where lifestyle and design blend into something meaningful.
At Western Timber Frame, we create more than pergolas and pavilions—we create outdoor spaces that promote wellbeing. For both residential and commercial settings, from poolside cabanas and garden retreats to timber structures at restaurants, resorts, hospitals, and senior living centers, our designs support a lifestyle that reconnects people with the natural world—where wellness begins.
Imagine…
- A shaded gathering place that filters soft morning light across your breakfast table.
- A garden workspace where your immune system clocks in before your breakfast.
- A cabana that turns your lunch break into a dose of healing infrared light and fresh air.
- A quiet timber bench beneath your arbor, where circadian rhythm syncs and screen fatigue fades.
It’s not just an aesthetic choice—it’s a lifestyle shift. One that requires no gym membership, no prescriptions, no screen-blocking apps. Just a place to step outside.
A Call to Rediscover the Obvious
As Dr. Seheult reflects, “Maybe hospitals should be outside.” The wisdom of veranda-era design—hospital beds that rolled into the sun—isn’t lost. It’s just waiting to be reclaimed.
This is your invitation to build differently. To gather in places where the air moves, the sun shines, and the body remembers how to heal.

You can’t bottle sunlight.
And yet, it lifts mood, fuels cells, and steadies the body clock.
That’s why your home—or workplace—should welcome it in.
