The Warm Evolution of Wellness: A History of the Infrared Sauna
The Modern Wellness Movement
Infrared saunas may feel like the latest wellness trend, but their story stretches across centuries of human healing, scientific discovery, and cultural tradition. Today, they’re a beloved part of modern self‑care — including right here at Salt & Soul Wellness — but their roots run deep.
Let’s take a journey through the history of the infrared sauna and discover how ancient wisdom and modern innovation came together to create one of the most soothing therapies available today.
Ancient Heat Traditions: Where It All Began
Long before infrared technology existed, humans instinctively understood the healing power of heat.
- Finnish cultures built saunas into hillsides as early as 2,000 years ago, using heated stones to create deep, penetrating warmth.
- Native American sweat lodges used steam and ceremony for purification and spiritual renewal.
- Roman bathhouses, Russian banyas, and Japanese onsen all embraced heat as a pathway to cleansing, relaxation, and community.
These traditions laid the foundation for what we now recognize as therapeutic sweating — the heart of sauna culture.
1800: The Discovery That Changed Everything
The story of infrared begins with science.
In 1800, astronomer William Herschel discovered infrared light while experimenting with sunlight and thermometers. He realized that invisible light beyond the red end of the spectrum produced heat — a breakthrough that would eventually make it possible to warm the body without heating the air.
This discovery planted the seed for the infrared sauna.
1891: The First Radiant‑Heat Sauna
Fast‑forward to the late 1800s, when Dr. John Harvey Kellogg invented the first radiant‑heat “light bath.” Using incandescent bulbs, he created a device that warmed the body directly — a revolutionary idea at the time.
He showcased it at the 1893 Chicago World’s Fair, and soon European royalty were using these early radiant saunas for relaxation and healing.
This was the first true ancestor of today’s infrared sauna.
1970s: Japan Brings Infrared Into the Wellness World
Modern infrared saunas as we know them were born in Japan.
In the 1970s, Japanese researchers developed the first far‑infrared heating panels, which gently warmed the body at lower temperatures. This innovation led to Waon Therapy (“soothing warmth”), a clinical approach still used in Japanese hospitals today.
This era marks the official beginning of the commercial infrared sauna.
1980s–Today: The Evolution of Infrared Technology
Infrared saunas have gone through several generations of improvement:
- Ceramic heaters (1980s): Strong but often too intense.
- Carbon panels (2000s): Gentler, more even heat.
- Full‑spectrum heaters (2010s): Marketed as multi‑wavelength options.
- Advanced composite technologies (2020s): Designed for optimal far‑infrared output and deeper therapeutic benefits.
Today’s infrared saunas are more comfortable, efficient, and effective than ever — which is why they’ve become a staple in wellness centers and homes worldwide.
The Modern Wellness Movement
Infrared saunas are now celebrated for their ability to:
- Support relaxation and stress relief
- Encourage circulation and recovery
- Promote gentle detoxification
- Pair beautifully with modalities like red light therapy and salt therapy
At Salt & Soul Wellness, we love infrared because it offers a deeply restorative experience without overwhelming heat — making it accessible to more people and more bodies.
Final Thoughts
The infrared sauna is more than a modern luxury. It’s the latest chapter in a long, beautiful story of humans using heat to heal — from ancient sweat lodges to cutting‑edge infrared panels.
Every time you step into an infrared sauna, you’re participating in a tradition that spans cultures, continents, and centuries.
