Heating Technology

Sunlighten™ uses infrared wavelengths to warm the body from within, resulting in a deeper sense of relaxation and a deeper sweat.  Infrared is a healthy and safe form of energy that is also naturally occurring in our own bodies.

Sunlighten offers 3 ranges of infrared saunas, using different forms of carbon heating technology:
  • The Solo System saunas – Solocarbon® Technology
  • The Signature® Series – Solocarbon® Technology
  • The mPulse Series Solocarbon® Full Spectrum Technology


What is Infrared?

Infrared light (experienced as heat) is the invisible part of the sun’s spectrum with the ability to penetrate human tissue.  Infrared sauna therapy uses this penetrating characteristic to heat the body directly at the core rather than simply warming the air or skin’s surface.  Sunlighten™ far-infrared saunas have been clinically shown to increase the body’s core temperature, resulting in a deeper sweat, benefiting your wellness goals.

How Safe is Infrared heat?

Infrared heat is completely safe and healthy for all living things.  You can be exposed to infrared light for hours without the risk of burning.  Infrared is a naturally occurring output of the sun, but does not contain the harmful UV rays associated with unprotected sunlight.  In fact, infrared heat is so safe that it is used in hospitals to warm newborn infants.

Infrared Saunas vs. Traditional Saunas

Infrared heat is very gentle.  The experience is similar to lying in the sun on a warm day and feeling the heat radiate to the core of your body.  Unlike traditional (hot rock or steam) saunas – which operate at well in excess of 90°C – infrared heat has the benefit of being effective at a more comfortable operating temperature of 40°-65°C.
Traditional saunas heat the air instead of the body directly.  Rather than inducing a deeper sweat and relaxation, this can make the experience unbearably hot and difficult to breathe.  Because infrared heat penetrates human tissue instead of simply heating the surface of the skin, infrared saunas are seven times more effective at cleansing the body than traditional saunas.  By raising the body’s core temperature, infrared saunas can produce a sweat composed of 20% toxins vs. only 3% toxins with a traditional sauna.

Solocarbon® Custom Spectrum® (mPulse)

mPulse HeaterNot all infrared heaters are created equally

Until now, infrared heaters have been made from either ceramic rods or a carbon blend.  Solocarbon® Full Spectrum changes the game with new elements that offer precise results. Among various infrared heating technologies, Solocarbon® Full Spectrum is unique in its ability to provide the full infrared spectrum at optimal wavelengths. This is accomplished with multi-layered heaters with distinct components to independently offer near-, mid- and far-infrared heat.  This matters because there are different health benefits associated with each part of the infrared spectrum, and some benefits that are best offered via a blend of wave- lengths.  mPulse’s Solocarbon® Custom Spectrum® is the only heater on the market with intelligent technology based on clinical data designed into it, in order to most precisely deliver the health benefits most sought after.

Solocarbon® heaters are thin, lightweight and flexible.

Solocarbon® Technology (Solo System)

In 2001, Sunlighten™ introduced the world’s FIRST carbon heater – SOLOCARBON®.  This breakthrough carbon technology would become the foundation of Sunlighten’s success.  It broke the mold by combining high far-infrared emissivity with the largest surface area. Why did Sunlighten™ choose carbon technology?  The answer is here.
Solocarbon® technology from Sunlighten™ remains to be the only infrared sauna technology on the market clinically shown to raise core temperature.  Contact Sunlighten™ today to find out why this is important. Solocarbon® panels (built into the walls of our saunas) contain a unique proprietary blend of materials that are 100% quality controlled by Sunlighten™.  This means – unlike other saunas on the market – we can ensure the safety & effectiveness of each individual heater.  Solocarbon® panels are heat-sealed, meaning no wires or glues are used, so there is no release of unhealthy gases during heating.  With clinically-backed Solocarbon® heating, it is no wonder our infrared saunas are the most trusted on the planet.

  • Solocarbon® heaters completely surround your body! No hot spots or cold spots anywhere in the sauna, so sit back, relax and immerse yourself in the soft gentle far-infrared heat from SunlightenTM.

The Evolution of Infrared Technology

The move from ceramic heaters… Up until the year 2001, ceramic based heaters were used in infrared saunas around the world.  In 1999, SunlightenTM began marketing wooden infrared sauna cabins using Ceramic Quantum Wave heaters – the largest heaters on the market. Sunlighten carbon vs. ceramic heaters  Sunlighten™ realised that in order to produce the far-infrared wavelength, you would need a heater that was large enough to work at much lower temperatures.  The general physics law (Wein’s Law of Displacement) states that a large surface area equals a lower surface temperature which then produces the long far- infrared frequency.  The small, hot bar heaters were getting too hot to sustain this longer frequency, therefore, users were not receiving the deeper sweat associated with the far-infrared wavelength

Introducing the World’s First Carbon Technology…

In 2001, Sunlighten™ introduced the world’s FIRST carbon heater – Solocarbon®.  This breakthrough carbon technology would become the foundation of Sunlighten’s success.  It broke the mould by combining high far-infrared emissivity with the largest surface area. This revolution by Sunlighten™ was originally met with angst from other industry providers.  To prove the faith that SunlightenTM had in their product, tests and studies were performed by independent testing bodies.  A clinical study in 2001 showed a rise in core body temperature, while in 2004, independent scientific testing was performed proving Sunlighten’s Solocarbon® heaters emitted 95% far-infrared. Since SunlightenTM introduced Solocarbon®, other carbon heaters (copies) started to flood the market.  These were mass produced, untested, and still emitted extreme high surface temperatures.

High surface temperature = Shorter Wavelengths

TODAY, there are many types of carbon heaters available – all based on the success of Solocarbon®, but none as effective.  SunlightenTM offers an industry standard carbon heater for the home user (the Select Series); the tested and proven Solocarbon® technology (the Signature Series and the Solo System) and the new WORLD FIRST Smart Infrared sauna – The mPulse Series, using Solocarbon® Full Spectrum heating elements.

Sunlighten near, mid and farAs beneficial as far-infrared heating is, continuing research by SunlightenTM showed that if far-infrared were blended with mid-infrared or near-infrared, the results would be beyond what far-infrared alone could accomplish. Sunlighten’s Solocarbon® Full Spectrum technology is the only technology in the world that can deliver dial-up of precise wavelengths, needed to target specific health benefits. Sunlighten™ have proved that they are industry leaders by revolutionising the infrared industry when they introduced Solocarbon® in 2001 and have done so once again with the release of their mPulse Series sauna featuring Solocarbon® Full SpectrumInfrared heater.
