Mahogany Clearlight® Sanctuary™ 2-Person Full-Spectrum Infrared Sauna

I have had the pleasure of trying many different saunas. For my sauna therapy programs, I did in-depth research into the operation and technology of home saunas. Depending on your health status, I have highlighted the features that bring a great experience and tons of health benefits.

On an average day, I probably recommend a full-spectrum infrared sauna to 85 % of my patients. Sure, a full-spectrum sauna looks brighter and more inviting…but is there more to it than that? Well, scientific research says “yes”. I’ll quickly show you the biggest differences related to health and healing. Then, I will tell you why the Clearlight® Sanctuary™ 2-Person Full-Spectrum Infrared Sauna is the best full-spectrum infrared sauna on the web/internet/country? 

What does full-spectrum mean?

A full-spectrum light is a light source that emits a wide range of wavelengths, including those in the visible spectrum (red, orange, yellow, green, blue, indigo, and violet) as well as those in the infrared non-visible (IR) ranges. A single-wavelength light, on the other hand, emits light at only one specific wavelength or narrow range of wavelengths.

Is full-spectrum better?

Full-spectrum light is thought to be more healing than single-wavelength light because it mimics the natural light of the sun and thus provides a more complete and balanced spectrum of light. This can help regulate the body's circadian rhythm, boost mood and energy levels, and improve the overall quality of sleep. Additionally, full-spectrum light is also used for a variety of therapeutic purposes, such as in phototherapy for certain skin conditions and seasonal affective disorder (SAD).

Full spectrum healing

A full spectrum infrared sauna allows a user to get the benefits of infrared therapy, red light therapy, phototherapy, NIR Near infrared, and FIR/far infrared therapy all in one. 

In contrast, using an infrared sauna that only uses ceramic heaters- you would only receive infrared therapy.

For the best Full-Spectrum infrared sauna at home, I recommend The Clearlight Sanctuary. Their most popular size is the 2-Person but all of the saunas in this product line use the same incredible technology. I can not say enough good(syn) things about this company. They have changed the field of home saunas to bring us a powerful healing machine that is a pleasure to use.

For the best Full-Spectrum infrared sauna at home, I recommend the Clearlight® Sanctuary™ 2-Person Full-Spectrum Infrared Sauna.
