The truth about infrared sauna therapy

The therapy was pioneered by NASA, who found infrared light helped plants grow in space. Extensive research in the early 1980’s led to the realization that infrared light treatments would be the perfect way to maintain cardiovascular conditioning in US astronauts for the duration of long space flights. Recently, they used this technology to treat patients suffering from the painful side effects of radiation and chemotherapy treatments. They discovered a phenomenal result—the infrared therapy was working as a healing agent, with no side effects! Since then, it’s been used by pain institutes around the country as a form of pain treatment, and the FDA has approved its therapeutic use.


What you will experience…. the world’s first and only infrared sauna that empowers you to customize each wavelength to optimize the specific health benefit you want.


Your wellness oasis awaits. Infrared therapy is a perfect supplement to any fitness routine.

So What is Infrared?

Nature brings us infrared light. It’s the healthy, healing rays that come from the sun. You’ve felt infrared your entire life. When you sit next to a fire or feel the warmth of the sun on your skin. Infrared also helps plants bloom and just the right amount helps stems grow fast and strong.


Infrared’s healing rays are felt on our skin as warmth, and are absorbed by our bodies to help them detoxify, relax, improve circulation, recover faster, sleep better, age well and help us feel good. The proof of this activity in our body is evidenced in the increase in core body temperature that happens during a 30-minute infrared sauna session. Sunlighten’s saunas are clinically-proven to raise core body temperature 3 degrees, which unleashes the most benefits to our health.

What is Near, Mid & Far Infrared Heating Technology?

Near Infrared (NIR) 

for Anti-Aging, Skin Health, Muscle Recovery 


  • Closest to visible light, acts more like it (like cousins) 

  • Absorbed at cellular level by mitochondria  

  • Shortest wavelength (700 to 1200 nanometers) 

  • Delivers most energy (like tiny dogs) 

  • Photobiomodulation/ low level light therapy (LLLT) used in cosmetic and healing  devices 

  • Triggers plants to use chlorophyll to convert light into tissue 


* Energizes cells best with precise 880nm wavelength, scientifically proven to: 

  • Recharge cell mitochondria 

  • Help reduce body fat 

  • Regenerate cells 

  • Reduce inflammation & pain 

  • Faster wound healing 

  • Increase collagen production/anti-aging 

* mPulse is world's only sauna with LED NIR 

Mid Infrared (MIR)

for Heart Health, Circulation, Pain Relief, Muscle Recovery


  • The "middle child" lives between near and far 

  • Mid-range wavelength (1.4 to 7 microns)  

  • Hardest IR to reproduce; used for sensory tools in various industries


  • Only our 3 in 1 heater delivers MIR at peak wavelengths (5 to 6.7 microns) • Made possible through our patented heating technology 

  • 3 distinct heating elements heat MIR layer to needed temp

Far Infrared (FIR)

for Detoxification, Heart Health, Weight Loss, Immunity, General Wellness,  Relaxation, Muscle Recovery 


  • The "independent oldest kid" lives farthest from visible light 

  • Longest wavelength (7-14 microns) 

  • Absorbed at the cellular level by water molecules 

  • Doesn’t warm the air, instead sends energy into objects 

  • Experienced as gentle, radiant heat 

  • Safely, gently improves health at the cellular level 

  • Human bodies also emit FIR energy, used in healing since ancient times (ex. Reiki)


  • Only FIR heater clinically proven to raise core body temp 3° 

  • Stimulates sweat glands, deep detoxifying sweat 

  • Energizes and revitalizes, not draining heat

  • SoloCarbon heaters are highest quality and quantity IR on market: 95-99% emissive
