For more than 25 years, Relax Sauna has been setting the standard for safe, effective, and science-backed infrared therapy. The company’s mission has always been simple: deliver the most advanced far infrared technology to people who want better health, faster recovery, and long-term wellness at home.
Relax Sauna is the only far infrared sauna that uses patented semiconductor chips registered with the FDA for therapeutic use in specific products within the Relax line. This advanced technology generates pure and consistent far infrared light without unwanted wavelengths, ensuring maximum safety and reliability. The result is faster heating, deeper penetration, and a sauna experience that is both safe and highly effective. Many users report feeling revitalized and balanced after each session, making it a trusted tool for daily wellness.
This purity and consistency are what make Relax Sauna truly unique. The precise far infrared energy produced by its semiconductor chips interacts naturally with the body, penetrating deep into muscles and tissues to stimulate circulation, encourage detoxification, and relieve tension from the inside out. Users often describe the sensation as “light soaking into every cell,” melting away stress and restoring calm to both body and mind. More than just a source of heat, the Relax Sauna delivers a deeply therapeutic experience that helps restore balance, accelerate recovery, and promote lasting vitality.
From a government-backed engineering challenge to a globally trusted wellness technology, here’s how Relax Sauna came to be.
Commissioned by the Japanese government, a Taiwanese engineering team set out to replicate the deeply restorative warmth of southern Japan’s hot springs—energies now known to be rich in far infrared radiation from surrounding mineral rocks.
Led by Dr. Chang, researchers developed a specialized semiconductor ceramic chip—engineered with far infrared materials and internal heating elements—to transform electricity into precise, therapeutic far infrared light in the 4–14 micron range.
The innovation that became Relax Sauna earned a Gold Medal Award at the American Pittsburgh Inventing Expo, recognizing its pioneering semiconductor-based far infrared design.
Every Relax Sauna continues to be crafted in Taiwan—renowned for semiconductor excellence—and embraced by wellness practitioners, athletes, and health-minded individuals around the world.
With a strong presence in the health and wellness community, the sauna is showcased at more than 40 major expos and conferences each year, including leading events in functional medicine, sports recovery, and biohacking. It has also been featured in interviews and podcasts with top wellness experts and continues to be recommended by practitioners worldwide.
Relax Sauna is used and recommended by thousands of people around the world including:
People turn to Relax Sauna to support detoxification, speed recovery, reduce stress, chronic illness support and to improve overall well-being.
Relax Sauna’s success in the American wellness market is closely tied to the work of Phil Wilson, a mathematician and long-time advocate for holistic health who has championed the sauna for more than two decades. After earning his degree with honors from Indiana University and pursuing graduate studies at Ohio State University, Phil experienced a powerful shift in the early 1970s that drew him into the world of natural healing.
Over the decades, he became one of the first to promote fasting, herbal medicine, pure nutrition, medicinal mushrooms, green powders, and oxygen therapies—long before they were widely accepted. His passion for holistic wellness and dedication to truth in health laid the foundation for what Relax Sauna would become.
In 2002, Phil was introduced to the Relax Far Infrared Sauna. Recognizing its unmatched technology and potential to change lives, he made it his mission to share its benefits with the world. Since then, he has showcased the sauna at more than 500 health conferences and personally introduced its healing effects to thousands of people.
Phil believes the Relax Sauna is the most impactful tool he has ever promoted, combining science, innovation, and personal freedom. His leadership has helped grow Relax Sauna into the trusted global brand it is today.
Relax Sauna is dedicated to advancing the science of far infrared therapy. We continually refine our technology, share education about the benefits of far infrared saunas, and provide wellness solutions that are supported by both research and real-world results.
For over two decades, our goal has been to empower individuals to take control of their health, one infrared session at a time.
Experience the Relax Sauna difference. Portable, powerful, and trusted around the world.
