Infrared Sauna: The Science

The Science Behind Infrared Saunas

Infrared light, experienced as heat, is the invisible part of the sun’s spectrum. The light waves go deep into your tissues to raise your core temperature, which burns calories, boosts metabolism, and also helps to dislodge toxins stored in cells.

We use Sunlighten Full Spectrum infrared saunas because they offer near, mid, and far infrared waves. This means that you get to experience the benefits of detoxification and healing at various depths. Also, this trifecta offers a much more complete detoxification experience than traditional saunas are able to provide. Our saunas are set so all three wavelengths are emitted in every session.

How Do Infrared Saunas Work?

We encounter electromagnetic waves in everyday life and infrared waves are part of this spectrum. These waves occur naturally from the sun and provide warmth, but they are entirely different from UV rays that can lead to sunburns and eventual skin damage. In fact, infrared rays are completely safe and offer numerous natural health benefits.

Infrared waves occur in three categories: near, mid, and far. Collectively, these rays penetrate the body and raise the core body temperature. Our Sunlighten Full Spectrum infrared saunas transmit heat through Solocarbon® heater panels, which deliver more infrared output than any other sauna in the world. With this technology, infrared rays deeply penetrate the skin and deliver healing and therapeutic benefits throughout the entire body in a gentle and soothing way.

Better yet, infrared saunas don’t require the excruciatingly hot temperatures that are characteristic of a traditional sauna. They function optimally at much lower temperatures of approximately 110 to 150 degrees F. By comparison, the average air temperature in a traditional sauna can easily reach up to 200 degrees F. This significant temperature difference makes infrared saunas much more comfortable and can provide greater clarity of mind.

Near Infrared Waves: Shortest waves that penetrate the epidermis (first 7 layers of skin)


  • Cell regeneration
  • Improved immunity
  • Skin rejuvenation

Mid Infrared Waves: Mid-range waves that increase cardiovascular activity


  • Pain relief
  • Improved circulation
  • Weight loss

Far Infrared Waves: Longest frequency waves that increases the core temperature of the body for a deep sweat at the cellular level where most toxins are stored


  • Detoxification
  • Relaxation
  • Blood pressure reduction
  • Weight loss
