What Makes Etanni's NIR Sauna Different
Technology that works with
your body's biology
Not all saunas are created equal — FireLight® near infrared heals from the inside out.
All saunas aim to raise your core body temperature to jumpstart the body's natural healing processes. While traditional saunas use steam or electric heaters to warm the air around you, Etanni's FireLight® near infrared sauna works with your body's biology to create radiant heat from the inside out.
By using near infrared's shorter wavelengths in a way that mimics natural sunlight, the light penetrates deeply — up to 9 inches into muscles, joints, tendons, and organs — triggering cellular-level healing that surface-level heat simply cannot reach. The result is a more comfortable, more effective, and profoundly therapeutic experience.
Unlike steam or far infrared saunas which only warm the skin's surface layers, FireLight® near infrared light reaches deep into muscles, joints, tendons, and internal organs — triggering cellular repair, improved circulation, and detoxification at the source rather than the surface.
The Science of Infrared Light
Where NIR sits in the
natural spectrum
Near infrared is the part of the sun's spectrum your body was designed to absorb and use.
Near infrared light occupies a unique therapeutic window in the electromagnetic spectrum — long enough to penetrate deep tissue, short enough to stimulate powerful biological responses at the cellular level. FireLight® technology isolates and delivers precisely this optimal therapeutic bandwidth, mimicking what nature has always provided.
The Difference That Matters
Near Infrared vs.
Far Infrared
Why Etanni chose FireLight® — and why the distinction changes everything.
(NIR)
- Penetrates up to 9 inches into tissue
- Mimics the natural sunlight spectrum
- Activates cellular photoreceptors in mitochondria
- Comfortable air temperatures — no suffocating heat
- Ultrafast heat therapy — effective, efficient sessions
- Stimulates collagen and elastin production
- Built-in phototherapy — no added LED panels needed
- Ultra-low EMF emissions for safe, daily use
- Raises core temperature by 3°F for deep detox
(FIR)
- Absorbed primarily by water in skin's surface layers
- Doesn't penetrate as deeply into tissue
- No photobiomodulation — no cellular light receptors
- Requires high air temperatures that feel stifling
- Takes longer to raise core body temperature
- No light therapy without added LED panels
- Limited spectrum compared to natural sunlight
- Higher EMF output in many popular units
- Less efficient at triggering deep cellular healing
Research-Backed Benefits
Nine dimensions of
deep healing
What happens when near infrared light meets human biology.
Heart Health
Improves cardiovascular function, reduces blood pressure, and mimics the effects of moderate exercise. Studies show significant decrease in cardiovascular disease risk with regular sessions.
Detoxification
Raises core temperature by 3°F, triggering deep sweating that helps eliminate toxins, heavy metals, and pollutants stored in fat cells — purifying at the cellular level.
Muscle Recovery
Accelerates muscle recovery after physical activity. Athletes use NIR therapy to improve performance, reduce soreness, and speed tissue repair after training and competition.
Skin Rejuvenation
Stimulates collagen and elastin production, reduces wrinkles, improves skin elasticity, and helps heal acne and skin conditions through deep photobiological action.
Mental Clarity
Reduces stress, anxiety, and depression. Promotes better sleep quality and enhances overall cognitive function through neurological and hormonal regulation.
Cellular Energy
Improves mitochondrial function, increasing cellular energy production (ATP) and enhancing overall vitality and endurance — energized from the inside out.
Pain Relief
Reduces chronic pain from conditions like arthritis, fibromyalgia, and tension headaches through deep tissue heating that reaches the source of discomfort.
Immune Support
Strengthens immune function, increases white blood cell counts, and reduces incidence of colds and flu by up to 30% with consistent regular use.
Wound Healing
Accelerates tissue repair and wound healing at all levels. Studies show dramatic improvements in recovery from injuries, surgical procedures, and chronic skin conditions.
Dual-Mechanism Healing
Two powerful pathways,
one session
Light therapy and heat therapy activate simultaneously — every time you sit inside.
(Photobiomodulation)
Your body has specialized receptors for red and near infrared light. When photons are absorbed by your cells' mitochondria, they trigger profound biological healing processes that improve function at the deepest cellular level — benefits you simply cannot get from heat alone.
- Reduces inflammation at the cellular level
- Stimulates blood flow and tissue oxygenation
- Enhances circulation throughout the body
- Promotes deep muscle and tissue relaxation
- Produces cellular energy (ATP) at the mitochondrial level
(Thermal Response)
Near infrared light creates radiant heat that raises your core body temperature by 3°F, triggering your natural detoxification and metabolic stress response — the same beneficial physiological cascade as vigorous aerobic exercise, without the physical exertion.
- Induces deep, therapeutic whole-body sweating
- Activates all major detoxification pathways
- Increases heart rate equivalent to moderate exercise
- Improves cardiovascular demand and function
- Supports metabolic function and caloric expenditure
FireLight® Technology
Engineered to
mirror nature
SaunaSpace's proprietary technology — tungsten filaments meet red-stained high-frequency hard quartz glass.
FireLight® combines precision engineering with natural spectrum principles to produce a full-spectrum infrared light that peaks in the optimal therapeutic wavelengths of red and near infrared, then trails gently into mid and far infrared — just like natural sunlight, but with harmful UV and blue light removed entirely for your protection.

The greatest testament to our work comes from the people we serve.
I enjoyed a much needed restful, yet energizing nap at Etanni while visiting family in Port Townsend! Gavin was fantastic — he has a wonderful and inviting space with a beautiful center. Clean and comfortable with easy access to the bathroom and blankets. The recliners were extremely comfortable as well! Will definitely visit again when we travel back out west!
This was the most amazing experience ever — truly healing. Gavin was truly such a great host. 10/10, best experience ever.
Etanni is so peaceful. It gives my mind and body an opportunity to relax and begin to heal. I look forward to more visits.
Very peaceful, relaxing and rejuvenating! I highly recommend a visit!

Your questions, answered
FireLight® is SaunaSpace's proprietary near infrared sauna technology. It combines tungsten filament incandescent bulbs with red-stained high-frequency hard quartz glass to produce a full-spectrum infrared light that peaks in the optimal therapeutic NIR and red wavelengths — mimicking the healing portions of natural sunlight while filtering out harmful UV and blue light.
The key difference is penetration depth and biological mechanism. Near infrared (NIR) light penetrates up to 9 inches into tissue, reaching muscles, joints, and organs — and activates specialized photoreceptors in your cells' mitochondria to trigger deep healing responses (photobiomodulation). Far infrared (FIR) is absorbed primarily by water at the skin's surface, doesn't penetrate as deeply, requires higher and less comfortable air temperatures, and your body has no specialized receptors for it — offering less cellular benefit.
Sessions are offered in 30-minute increments. Many clients begin with one 30-minute session and increase frequency as their body adapts. Because FireLight® heats you directly and efficiently, therapeutic core temperature is reached faster than traditional saunas — delivering powerful benefits in less time. Core Annual Members enjoy unlimited access and may use the sauna as often as desired during open hours.
Hydrate well before your session. Remove jewelry and wear minimal, natural-fiber clothing or a towel. After your session, allow 10–15 minutes to cool down naturally before showering, then rehydrate thoroughly. Many clients pair the NIR Sauna with The Light System™ for a comprehensive healing protocol — ask our team about recommended sequencing for your specific wellness goals.
Yes. Near infrared sauna therapy has an extensive research record supporting its safety and efficacy. FireLight® technology emits ultra-low EMF — lower than most common household appliances — and produces no harmful UV or blue light. As with any heat therapy, those with certain medical conditions, pregnancy, or cardiovascular concerns should consult their healthcare provider before beginning. Individual results may vary.
Absolutely — and many clients find the combination powerfully synergistic. The NIR Sauna pairs especially well with The Light System™, as both support cellular health and biofield coherence through complementary mechanisms. Bio-Well scanning can be used before and after a series of sessions to track measurable changes in your energetic state. Ask our team for a personalized wellness protocol.
