Proven Health Benefits
What regular heat and red / near-infrared light therapy have been shown to support in published research.
Chronic Pain Relief
Pain scores often drop by 20–70% in studies
Learn more
Infrared and sauna therapies studied alongside standard care for fibromyalgia, arthritis and
low-back pain have shown substantial reductions in pain, stiffness and day-to-day discomfort
over time.
Skin Rejuvenation
About 30% increase in collagen density in LED trials
Learn more
Red and near-infrared light have been shown to boost collagen, improve elasticity and smooth
the look of fine lines and uneven texture with several weeks of consistent use.
Faster Recovery
Athletes show quicker strength & performance recovery
Learn more
Red and near-infrared light have been shown to help reduce post-workout soreness and support
faster recovery of muscle strength and performance compared with placebo in sports trials.
Weight Management
Energy burn similar to moderate cardio
Learn more
Infrared heat can raise heart rate and circulation like brisk walking or light jogging, helping
your body burn additional calories during a typical 30–40 minute session, alongside diet and exercise.
Better Sleep
Supports relaxation & improved sleep quality
Learn more
Sauna sessions help the body unwind and are associated with lower perceived stress and improved
self-reported sleep quality, making it easier to relax at night.
Immune Support
More white blood cells & fewer colds
Learn more
Sauna studies report temporary rises in key immune cells after heat exposure and fewer common
colds in people who use saunas regularly, supporting everyday immune resilience.
Mood & Mental Well-Being
Large mood improvements in heat & light trials
Learn more
Whole-body heat and red-light studies have reported meaningful reductions in depressive symptom
scores, while many people simply feel calmer, lighter and more balanced after regular sessions.
Longevity
Frequent sauna use linked to longer, healthier life
Learn more
Long-term Finnish cohort studies associate 4–7 sauna sessions per week with a lower risk of fatal
heart events, high blood pressure and all-cause mortality, suggesting regular heat exposure may
support healthy aging.

The Science of Dual Therapy
Infrared heat and red light therapy work together synergistically-each amplifying the other's benefits for results you can feel from day one.
Full Spectrum Infrared
Far, mid, and near-infrared wavelengths penetrate deep into muscles, joints, and tissues-promoting circulation, reducing inflammation, and inducing deep relaxation through gentle, penetrating heat.
- • Reaches 1.5 inches deep into tissue
- • Increases blood flow by up to 54%
- • Burns 400-600 calories per session
Medical-Grade Red Light
Clinically validated wavelengths (630-850nm) work at the cellular level through photobiomodulation-stimulating mitochondria to produce more ATP (cellular energy) and collagen for repair and rejuvenation.
- • Boosts cellular energy (ATP) by 200%
- • Increases collagen production by 31%
- • Accelerates healing and recovery
Transformative Results
Heat opens your pores and increases circulation. Red light penetrates deeper to repair at the cellular level. The combination creates a compound effect-delivering benefits neither therapy can achieve alone.
Red Light and Infrared Light: Why They Work Better Together
Arki Duo combines red light with full-spectrum infrared to reach the body at multiple depths. Each wavelength serves a specific purpose, and together they provide a more complete response than a single wavelength.
Red Light (630–660 nm) - Surface-Level Support
Red light targets the upper layers of skin, supporting collagen, calming visible inflammation, and aiding recovery in tissues stressed by daily movement.
Full-Spectrum Infrared (Near, Mid, Far) - Deep Tissue Support
Full-spectrum infrared penetrates from shallow to deep tissues:
- Near Infrared: Reaches muscles and joints to reduce stiffness, calm deeper inflammation, and support circulation.
- Mid Infrared: Gently warms soft tissues, improving flexibility and easing tension.
- Far Infrared: Penetrates deeply to raise core body temperature, encourage circulation, and promote relaxation and detoxification.
The Red and Infrared Effect™
Red and infrared wavelengths complement each other and don’t cancel each other out. The gentle warmth from infrared helps increase blood flow, allowing red light to reach tissues more efficiently. Studies show that using both together produces stronger benefits than using either wavelength alone.

Your Questions Answered
Everything you need to know about the Arki experience
How is Arki different from a traditional sauna?
Traditional saunas only provide heat. The Arki Collection combines full-spectrum infrared heat with medical-grade red light therapy, giving you dual benefits: deep tissue healing from infrared PLUS cellular rejuvenation from red light. It's like getting a sauna session and a red light therapy treatment at the same time - for 2X the results.
How often should I use my Arki sauna?
For optimal results, we recommend 3-7 sessions per week, 20-30 minutes each. Daily use is safe and beneficial. Many users start with 3 sessions per week and work up to daily use as they experience the benefits. Consistency is key, regular use produces cumulative, long-term health improvements.
Is the red light safe for my eyes?
Yes, red and near-infrared light are completely safe for your eyes and don't cause damage like UV light. However, the LEDs are very bright, so you may want to close your eyes or use the goggle provided for comfort. You can also turn them off if preferred,the infrared therapy will still be fully effective.
What does "medical-grade" red light mean?
In Arki, “medical-grade” refers to the quality and precision of the LEDs and engineering standards - similar to those used in professional wellness equipment. The system operates within the red and near-infrared light spectrum known for supporting skin health, recovery, and relaxation.
Disclaimer: The Arki Sauna is intended for general wellness use and is not a medical device. It is not designed to diagnose, treat, cure, or prevent any disease.
Will I see results immediately?
Many users report feeling more relaxed, experiencing reduced pain, and sleeping better after just one session. Visible skin improvements typically appear within 2-4 weeks of consistent use. Deeper benefits like weight management, chronic pain relief, and immune support build progressively over 8-12 weeks of regular sessions.
How much does it cost to operate?
Very little! Thanks to our DualShield™ insulation and energy-efficient design, the Arki costs approximately $20-35 per month in electricity for typical daily use (based on average US rates). That's less than a single massage or spa visit, for unlimited daily wellness sessions.
What's included with my purchase?
Every Arki sauna includes: the complete sauna unit with ArkiGlow™ Dual Therapy System, Bluetooth audio system, tempered glass door, LED control panel lighting, detailed setup instructions, 5-Year comprehensive warranty, and lifetime customer support. White glove delivery available for certain Southern California areas.
Do you offer financing?
Yes! We offer flexible, No-Interest Financing options with Affirm (starting as low as $278/month with approved credit). This makes it easy to bring professional-grade wellness therapy into your home without the upfront investment. Apply during checkout to see your personalized payment options.
