Proven Health Benefits
Discover the science-backed benefits of sauna therapy
Chronic Pain Relief
Pain scores often drop by 20–70% in studies.
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.
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.
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.
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.
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.
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.
Regular sauna use can increase white blood cell production, helping your body fight off illness and infection more effectively.
Longevity
Frequent sauna use linked to longer, healthier life.
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.
What Makes the Arki Stand Out?
Designed for the ultimate wellness experience, fusing advanced therapy technology with premium craftsmanship.
Red + Full-Spectrum Infrared
Combines red light with near, mid, and far infrared wavelengths for comprehensive coverage, from skin and superficial tissues to muscles and joints.
Ultra-Low EMF/ELF
Third-party lab tested (average 0.32 mG at the heater surface) to keep EMF and ELF exposure exceptionally low, even during long, frequent sessions.
Smart Modular Construction
A thoughtfully engineered panel system delivers a rock-solid cabin with clean lines, minimal visible hardware, and stress-free assembly in your space.
Modern, Minimal Design
Clean lines and a glass front create a spa-like, Scandinavian-inspired focal point that blends seamlessly into modern homes.
Flexible Dual-Therapy Design
Unlike typical saunas that lock you into one mode, Arki lets you run infrared only, red light only, or both together, perfect for days when your body only needs one type of therapy.
Gentle, Balanced Heat
Full-spectrum infrared provides soothing warmth that supports circulation, relaxation, and deep sweating, without feeling harsh or stifling.
Intuitive Digital Control
A slim, all-in-one digital panel lets you adjust temperature, session time, and therapy modes with just a few taps.
Premium, FSC-Certified Hemlock
Crafted from untreated Canadian Hemlock, chosen for its smooth finish, neutral aroma, and warm, natural wood grain.
Use infrared heat alone, or add red light for deeper recovery and radiance.
Deep, even heat for calm and recovery.
Infrared Only
Recovery and glow, beyond heat alone.
Dual Therapy
Red Light and Infrared Light
Why They Work Better Together
Arki combines red light with full-spectrum infrared to reach the body at multiple depths. Each wavelength serves a specific purpose, providing a more complete response than a single wavelength alone.
RL
Medical-Grade Red Light
630–660 nm • Approx. depth: 5–10 mm
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. Targets the epidermis and dermis layers - think of it as a “surface reset” for skin and cellular health. It supports collagen production and helps calm visible redness.
Surface Inflammation & Redness
Skin Rejuvenation & Glow
Supports Faster Skin Repair
IR
Full-Spectrum Infrared
Near, Mid, Far Infrared • Approx. depth: 20–40 mm
Reaches deeper into muscles and joints - like a “deep clean” for your body’s recovery systems. It gently raises core body temperature to support circulation and natural detox pathways.
Deep Inflammation: Joint discomfort & stiff muscles
Recovery: Muscle relaxation and post-workout relief
Detox Support: Promotes sweating to help flush impurities

Technical Superiority
Built from the ground up, Arki pairs refined design with engineered performance for a more complete, consistent experience.
Infrared sauna is one of my favorite ways to help support detoxification. It's also incredibly relaxing. My husband and I fit comfortably in it and this is something I tried to use 3 - 4 times a week to help with detoxing mercury.
The combination of 360° heat and medical grade red light therapy are an absolute game changer. If you're looking for the best, look no further. I use the Arki as a crucial part of my training and recovery routine.

This is theBEST recovery purchase I’ve ever made. It was simple to put together and I NEVER thought that an undated sauna would ever get hot enough but this exceeded my expectations by a mile.
I cannot say enough, amazing things about this sauna/red light therapy combo! The quality is unreal ! It feels luxe, sturdy, and thoughtfully designed. After just a few sessions, I started noticing the benefits. My acne cleared up, I started to look more glowy and I have been sleeping better.
Absolutely love my Arki red light sauna! It was so simple to set up & really feel the effects in just a few uses! Excited to see how long this system will hold up compared to cedar but overall great design!
Thank you so much for sharing your experience, Heather! We're thrilled to hear that you're loving your Arki red light sauna and that setup was simple and intuitive. It's great to know you're already feeling the benefits after just a few uses.
The Arki line was thoughtfully designed with both performance and durability in mind, and we truly appreciate your feedback as you continue to enjoy it over time. If you ever have any questions or need assistance down the road, our team is always happy to help.

BEST recovery purchase ever
This is the BEST recovery purchase I've ever made. It was simple to put together and I NEVER thought that an undated sauna would ever get hot enough but this exceeded my expectations by a mile. I couldn't be happier and I usually never take time to write reviews.

We're thrilled to hear that your sauna exceeded your expectations, both in heat performance and ease of assembly. Knowing it's become your top recovery purchase means a lot to us. If you ever have questions or need anything along the way, we're always here to help!

ABSOLUTELY OBSESSED — GAME CHANGER!
I cannot say enough, amazing things about this sauna/red light therapy combo! The quality is unreal — it feels luxe, sturdy, and thoughtfully designed.
After just a few sessions, I started noticing the benefits. My acne cleared up, I started to look more glowy and I have been sleeping better. You can also use the red light therapy alone without turning the sauna on, which is perfect for the nights when I don't have time to sweat it out.
It's the perfect place to unwind, meditate, or just disconnect for 20 minutes. I actually look forward to it every single day.
If you're thinking about investing, do it. This is one of those purchases you feel instantly and genuinely grateful for. JNH Lifestyles knocked it out of the park with this one — I'm obsessed!
Hi Hannah,
Thank you so much for sharing such an amazing review. We are thrilled to hear how much you're loving the sauna and red light therapy combination. It's wonderful that you're already seeing benefits like clearer skin, a healthy glow, and better sleep. We designed this unit to feel luxurious, sturdy, and versatile, so it means a lot to hear that it's become your daily place to unwind and reset.
We're grateful for your kind words and thrilled that this has become such a meaningful part of your routine. If you ever need anything at all, we're always here to help!
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.
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.
