JNH Lifestyles’ Arki Sauna: Combining Red Light Therapy and Infrared Heat in One Recovery System

Biohack Yourself APR 2026

Recovery tools are often designed around a single approach. Some focus on heat, while others rely on light therapy to stimulate cellular activity. In practice, however, the body does not operate in isolated systems. Circulation, cellular repair, muscle recovery, and skin health are all interconnected, which is why some wellness technologies attempt to combine multiple therapies within a single environment.

JNH Lifestyles approaches this idea with the Arki™ Duo 2-Person Medical-Grade Red Light Therapy + Full Spectrum Infrared Sauna, a cabin designed to deliver red light photobiomodulation and full-spectrum infrared heat simultaneously. By pairing these therapies in a single space, the system aims to create conditions where light exposure and heat-induced circulation work together during the same session.

Situations Where Dual-Therapy Recovery May Be Useful

A combined heat and light therapy environment can be especially relevant in situations where the body is under physical or metabolic stress.

After intense workouts, for example, muscles and connective tissues often experience tightness or localized inflammation. Heat from infrared wavelengths may help increase circulation and promote relaxation in deeper tissues, while red light therapy is commonly studied for its potential role in supporting cellular energy production and tissue repair.

Long periods of sedentary work or travel can create a different kind of strain. Sitting for extended hours may lead to stiffness in the lower back, hips, and shoulders. Gentle infrared heat combined with targeted light exposure may help loosen tight muscles and encourage blood flow during recovery sessions.

The technology may also appeal to individuals interested in skin-focused wellness routines. Red light wavelengths in the 630–660 nm range are often used in photobiomodulation because they interact with superficial skin layers and may support processes associated with collagen production and skin renewal.

How Light and Heat Work Together

The Arki sauna is built around a concept of 360° photobiomodulation, meaning red and near-infrared light emitters surround the user rather than coming from a single panel. This design removes the need to rotate the body during treatment sessions, allowing light exposure to reach the body from multiple directions.

The cabin incorporates wavelengths ranging from 630 nm to 850 nm, commonly used in red and near-infrared therapy. These wavelengths are frequently studied for their interaction with mitochondria, where they may help stimulate ATP production—an essential part of cellular energy metabolism.

Alongside light therapy, the sauna delivers full-spectrum infrared heat that can reach temperatures up to 170°F. Infrared heat is often used in wellness environments because it penetrates tissues more gradually than conventional dry heat, creating a warming effect that may support circulation, muscle relaxation, and sweating.

By combining these elements, the Arki system attempts to take advantage of heat-induced vasodilation, a process where blood vessels widen in response to warmth. Increased circulation may help deliver oxygen and nutrients more efficiently throughout tissues at the same time that light therapy is occurring.

A Flexible Recovery Environment

Another feature that distinguishes the Arki design is its dual-therapy flexibility. Users can run infrared heat only, red light only, or both together, depending on the type of recovery or wellness session they want.

For example:

• Heat-only sessions may be used for deep sweating and muscle relaxation

• Red-light-focused sessions may appeal to users prioritizing skin or cellular recovery

• Combined sessions allow both systems to operate simultaneously for a more integrated experience

This flexibility allows the sauna to adapt to different needs rather than locking users into a single mode of therapy.

Engineering and Safety Considerations

Because sauna sessions often involve extended periods inside the cabin, environmental factors such as electromagnetic exposure and material safety can become important considerations.

The Arki sauna is designed with ultra-low EMF and ELF output, with third-party testing reporting an average of approximately 0.32 milligauss at the heater surface. This measurement is notably lower than that of many conventional electrical devices and may appeal to individuals who prefer minimizing electromagnetic exposure during longer wellness sessions.

The interior is constructed from FSC-certified Canadian Hemlock, a wood known for its neutral scent and durability. The cabin is also built with zero-VOC materials, reducing the presence of chemical emissions often associated with treated woods or adhesives.

Together, these features aim to create a sauna environment that feels both comfortable and chemically clean.

Designed for Home Wellness Spaces

The Arki Duo is built as a two-person cabin measuring approximately 47.3 inches wide, 39.5 inches deep, and 75 inches high, making it compact enough for many home wellness spaces while still allowing room for shared sessions.

Its digital control panel allows users to adjust temperature, therapy modes, and session timing through a single interface. The sauna’s modular panel system also simplifies installation, allowing the unit to be assembled with relatively minimal hardware and integrated into a variety of home layouts.

Visually, the design leans toward a minimal Scandinavian aesthetic, with clean lines and a glass front that allows the cabin to function as a focal point within a wellness room rather than a purely utilitarian device.

A Combined Approach to Recovery and Wellness

Wellness technology continues to evolve toward systems that integrate multiple therapeutic inputs rather than relying on a single method. By combining medical-grade red light therapy with full-spectrum infrared heat, the Arki sauna reflects this broader shift toward more layered recovery environments.

For individuals exploring ways to support recovery after training, ease muscle tension from long days, or incorporate light therapy into their wellness routines, a dual-modality system like Arki may offer a more comprehensive option than standalone heat or light therapies alone.
