Key Features

Why Choose the Sanctuary™ 3?

Clinically Studied Benefits

A UCSF clinical trial showed 91.6% of participants improved beyond depression criteria after infrared heat sessions combined with CBT.

Doctor-Designed PEMF Technology

10 strategically placed PEMF cores deliver targeted frequencies to support full-body healing, relaxation, and recovery.

Easy-Clean Mat Covers

Extra mat covers help keep your PEMF Mat clean and fresh—available individually or in value bundles.

Low EMF/ ELF

Using ultra-sensitive testing equipment, our proprietary heaters cancel out both EMF and ELF, making them the safest on the market.

Recognized Sleep Support

Called “the most rewarding sleep tool” by CNET for its deeply relaxing, sleep-promoting effects.

Therapeutic PEMF Frequencies

Four optimized frequency levels promote deep relaxation, stress relief, grounding, and improved mental clarity.

True Wave Low EMF Infrared

The composition is a high-quality organic carbon fiber sheet comprised of micro-thin carbon fibers (1/1000th the thickness of a human hair), combined with our high output (high emissivity), patented ceramic compound. The result: True Wave low EMF Far Infrared heating elements inside the dome that produce long-wave infrared heat unequaled by carbon heaters alone with the majority of EMF (Electro Magnetic Fields) canceled out, making the Curve the safest and most effective sauna dome available.

Infrared Amethyst PEMF Mat

Doctor-designed and featuring 10 strategically placed PEMF cores and 12 layers, personally crafted by Dr. Duncan to maximize healing benefits and comfort. With over 25 lbs of pure amethyst crystals, combined with low EMF far infrared heat—the mat generates infrared wavelengths between 6-14 microns, and with a frequency range of 3Hz – 23Hz. The PEMF frequencies have been carefully designed to promote whole-body healing with specific benefits for each waveform:

  • Level 1 / 3Hz: Promotes relaxation and deep sleep
  • Level 2 / 7.8Hz: Enhances grounding and calming effects, ideal for recharging and reconnecting after day-to-day stress
  • Level 3 / 10Hz: Reduces stress and encourages mindfulness, aiding in improved focus and memory
  • Level 4 / 23Hz: Enhances mental function, concentration, and memory

"The far infrared is the only thing that took away the daily inflammation in my knee that made me limp by the end of the day. After two months, I felt improvement, and with daily use, I've experienced less stiffness, less puffiness, more energy, and even some weight loss."

My Symptoms Were Gone in Six Weeks

After using my infrared sauna every day for six weeks, I can honestly say my symptoms are gone. The stiffness and hives I was experiencing have completely disappeared, and even the pain from two shoulder surgeries is gone. I have more energy, I've lost weight, my skin looks better, and I feel healthier overall. This is one of the best gifts I've ever given myself.
