What is Infrared Light Therapy?
The invisible light your body has evolved with—and one of the most researched technologies in modern preventive wellness.
Every second of every day, your body is powered by light.
Not just the light you see—but wavelengths you can't.
One of those wavelengths is infrared light.
It makes up more than half of the sun's energy reaching the Earth and has been part of human biology for millions of years. Unlike ultraviolet (UV) light, which can damage skin, infrared light is naturally absorbed by the body and converted into heat and biological energy.
This isn't alternative medicine. It's physics. And increasingly, it's medicine.
Today, infrared light is used by elite athletes, longevity physicians, rehabilitation clinics, NASA researchers and hospitals around the world to support recovery, circulation, pain management and cellular health.
At HEALUX, we've brought one of the world's most advanced full-spectrum infrared technologies to Brussels because we believe this shouldn't be reserved for professional athletes or specialised clinics—it should be accessible to anyone who wants to invest in their long-term health.
Light Is More Than Heat
A traditional sauna heats the air around you.
Infrared light heats you.
Instead of warming the room first, invisible infrared wavelengths penetrate the body, where they are absorbed by tissues, muscles, blood vessels and cells. Your core temperature rises more efficiently while remaining in a comfortable environment, creating a deep physiological response rather than simply sitting in a hot room.
Why Your Body Responds So Well
Every cell in your body requires energy.
That energy comes from tiny structures called mitochondria—the body's power plants.
Research shows that specific wavelengths of red and near-infrared light stimulate mitochondrial function, helping cells produce more ATP, the energy molecule that powers everything from muscle repair to brain function.
Mid and far infrared gently warm tissues from within, increasing circulation, promoting relaxation and supporting the body's natural recovery mechanisms.
Full Spectrum Makes All the Difference
Most infrared saunas produce only far infrared.
At HEALUX, we use the Sunlighten mPulse Smart Sauna, capable of delivering all three therapeutic wavelengths independently.
• Near Infrared (NIR): supports cellular energy, collagen production and skin renewal.
• Mid Infrared (MIR): supports muscles, circulation and recovery.
• Far Infrared (FIR): promotes deep sweating, cardiovascular conditioning and relaxation.
Together, these wavelengths create a therapeutic experience that no single wavelength can achieve alone.
Science You Don't Need to Understand
The Sunlighten mPulse automatically adjusts the balance of near, mid and far infrared depending on your wellness goal.
Available programmes include:
• Recovery & Pain Relief
• Detoxification
• Heart Health
• Relaxation
• Weight Management
• Healthy Ageing
The technology does the science, so you can focus on feeling your best.
Why People Feel So Different Afterwards
Clients often expect to simply sweat.
Instead, they leave feeling lighter, calmer, mentally clearer, more energised and deeply refreshed.
Research has associated infrared therapy with improved circulation, recovery, sleep quality, stress regulation, cardiovascular health, skin appearance and overall wellbeing.
Why We Created HEALUX
We didn't open HEALUX because Brussels needed another sauna.
We created HEALUX because we believe preventive health should be simple, accessible and grounded in science.
Infrared therapy offers an opportunity to support your body before problems become chronic—a place dedicated to recovery, resilience and long-term wellbeing.
The Future of Wellness Is Preventive
The future of healthcare isn't only about treating disease.
It's about helping people stay healthier for longer.
Infrared therapy works with the body's own biology to support recovery, resilience and wellbeing.
At HEALUX, our mission is simple:
To make one of the world's most researched wellness technologies part of everyday life.
