Research and Development
They are the cornerstones of High Tech Health. We have been designing infrared saunas longer than any other company in America, and we lead the industry in research. As a result, our infrared sauna heaters have the best function and features in the industry.


Ideal Spectrum™
Infrared is a band of light that we experience as heat. The light is converted to heat by a process called resonant absorption. That’s a process where the infrared light transfers energy to the body when bonds in particular molecules resonate. Those molecules can be water, melanin (in your skin), or hemoglobin (in your blood).
Our heaters are Ideal Spectrum™ heaters. That means that they only emit far infrared, which only resonates with water molecules. This is the safest and healthiest infrared, and responsible for all of the health benefits found in studies of infrared saunas.

The Science of Resonant Absorption
It’s not just heat; it’s resonance.
Most saunas rely on heating the air to uncomfortable temperatures that just scorch your skin. Our Ideal Spectrum™ heaters emit a specific bandwidth of Far Infrared light tuned to the absorption peaks of the water molecules in your body.
This creates Resonant Absorption:
-
Efficient Absorption: The light energy is instantly converted into heat the moment it hits your body, rather than bouncing off or wasting energy on the air.
-
Raises Core Temperature: This efficient absorption allows the heat to radiate inward, raising your core body temperature effectively without needing unbearable air heat.
-
Superior Detox: Triggers a heavy, detoxifying sweat at lower, more comfortable temperatures.
Comprehensive Lowest Total EMF
EMF are the electric and magnetic fields that emanate from all electronics. At levels seen in most saunas, they can rob the body of antioxidant resources and cause DNA strand breakage.
Our entire sauna has complete EMF mitigation, which includes both electric and magnetic fields. The High Tech Health-designed infrared heaters feature our patented Triple Antifield™ technology for EMF mitigation.
Vitatech Electromagnetics, the industry’s standard EMF evaluation company, evaluated our heater’s EMF. Instead of random spot testing or directing where they test, we asked for a report of the HIGHEST fields they could find. Compare this with other manufacturers that report and display only the lowest numbers found. Transparency goes a long way. While many of our measurements were lower, we display the highest ones.
Our EMF report is only 6 pages long because it’s free of unnecessary details disguising the results. Page 3 tells you everything you need to know.

| Feature | High Tech Health (Transcend® Heaters) |
Standard Panel / Carbon |
|---|---|---|
| Heat Delivery | Focused Resonance Proven 34% more emissive via calorimetry | Dispersed / Unfocused Relies heavily on warming the air (convection) |
| Emitter Power Up | Max Output in < 5 Mins Instant, high-intensity infrared output | Slow Ramp-Up Takes longer to reach effective emissivity |
| Session Ready | 10 - 30 Minutes Depending on preferred intensity | 45 - 60+ Minutes Must heat large volume of air first |
| EMF Levels (Electric & Magnetic) |
0.089 V/m | 0.36 mG Virtually undetectable levels | High (Often > 30 V/m) | 80 mG Frequently exceeds safety thresholds |
| Heater Lifespan | Lifetime Durability Zero failures in company history | 3-5 Years Materials degrade over time |

A 34% More Effective Infrared Sauna
We compared the Transcend infrared heater architecture to the panel heater architecture. With some variation, the panel heater architecture is found in all of the other leading brands of infrared saunas, and is identifiable by the huge inside wall space that the heaters must cover.
In this side-by-side infrared heater comparison video, you see a time-lapse recording of the Transcend infrared sauna next to a panel heater sauna. A beaker of water sits in front of a heater in each sauna. The beaker in the Transcend sauna heats a massive 34% faster!
This is possible because Transcend heaters produce more infrared for the inside of the cabin and direct it better toward you. This means significantly more infrared for superior health benefits, faster warm up time, and greater power efficiency saving you money on your electrical bill.

3rd-Party Safety Tested

Transcend infrared heaters are one of the only infrared heaters that have been 3rd-party safety tested. This is because they are one of the only infrared heaters that can meet U.L.’s strict design requirements.
Underwriters Laboratory (U.L.) is a company that creates standards and evaluates the safety of products. Our heaters are a UL recognized component, which means UL has approved them and their materials for safety.
