Breaking bulletin — from the editor who tested 6 infrared saunas back to back

I Tested 6 Infrared Saunas.
The Weird Silver Tent
Beat Them All.

Five left me drained. One left me energized. Here is the physics that explains why and what happened to my heavy metals, chronic inflammation, and blood pressure in 60 days.

★★★★★4.8 out of 5 — 3,200+ verified reviews

My name is Rex. I am the Co-CEO and Editor of GadgetReview.com. I have tested hundreds of products. And I have to tell you something that took me years to admit: I was wrong about this sauna.

There is a clear winner — Relax Saunas and their patented semiconductor chip technology. It's why Dr. Boz and the LA Dodgers swear by them. And why we do too.

Gadget Review
GadgetReview.com published 2026

I walked past it at every health expo I attended. Conscious Life Expo. Dave Asprey events. Health conferences. Biohacking rooms. Practitioner booths. All of it. I saw the same silver nylon tent sitting there year after year. And I kept walking.

Not because I had tested it and found it lacking. Because I thought I already knew better. It did not look serious. It did not look luxurious. It did not look like the $5,000 wooden infrared saunas people proudly install in their homes.

It looked like a silver tent. And honestly, I dismissed it.

Meanwhile, I was doing everything else. Red light therapy. Cold plunges. Supplements. Binders. Hot yoga. Coffee enemas. Parasite cleanses. Water filtration. Air filtration. Even a cheaper infrared sauna from Amazon.

My HTMA and spectroscopy scans showed heavy metal poisoning. My biomarkers had improved in some areas, but something was still missing.I had spent years focused on what I was putting into my body. But the lesson I eventually had to learn was this:

“It is not only what you put in your body. It is what you take out of it."

When I finally agreed to review the Relax Sauna for GadgetReview's portable infrared sauna guide, I ran a proper test. 1Love. Therasage. Sunlighten. A couple of others. Six total.

I measured heat-up time, sweat time, how I felt during the session, and how I felt after.

The Relax Sauna raised my heart rate and core temperature faster and more effectively than anything else I tested. And after the session, I felt relaxed and energized at the same time — something the other five never produced.

That difference is not a feeling. There is a reason for it. And once you understand it, you cannot unsee it.I listed the Relax Sauna #1 in our Best Portable Infrared Sauna guide.

Not because of the way it looks. Because of what it does to your body that nothing else in the category does. I called it the Beetle that beat the Ferrari. I overlooked it for years. I was wrong.

That is when I realized the ugly little silver tent I had judged on looks was not a cheap compromise. It was the engineering solution.

Two Jars of Sweat. One Massive Difference.

There is a difference between sweating and detoxing. That is the part almost nobody tells you.
A gym sweat is mostly water and salt.
A hot yoga sweat is mostly water and salt.
A conventional sauna sweat is often forced by high ambient heat.

You sit in 160 to 175 degrees, your skin gets hot, your body tries to cool you down, and you perspire. That is not the same as a deep far infrared sweat.

Left: ordinary sweat. Right: sweat collected after a Relax Sauna session, carrying metabolic waste, heavy metals, and fat-soluble toxins.

The number one way to effectively detox the body from heavy metals, plastics, toxic chemicals, and parasites stored deep in fatty tissues is not just binders like zeolite, activated charcoal, or chlorella.

It is not only bitter herbs like wormwood, black walnut, clove, or soursop.

It is not detox baths with Epsom salts, magnesium, and ginger.

It is not only chelating cilantro for mercury or yellow dock for lead.

It is not castor oil packs over the liver.

It is not coffee enemas or garlic shots.

It is not cold plunges or breathwork.

And it is certainly not sitting for an hour in a dry wooden sauna at 170 degrees just to wipe yourself out.

Those tools may have their place. But they are not the exit pathway.

The exit pathway is a deep, cellular, toxic sweat created by the right far infrared sauna.

That means far infrared energy that penetrates beyond the surface and reaches the tissues where fat-soluble toxins, heavy metals, environmental chemicals, and metabolic waste accumulate.

That is what I had been missing.

If You Crash at 2 PM, It May Not Be Age

If you are dealing with afternoon brain fog, stubborn joint stiffness, chronic inflammation, poor sleep, or energy that crashes by 2 PM, it may not simply be stress. It may not simply be aging. It may be accumulation.

We live in a world where toxins are coming from every direction.

The problem is that the modern toxic load is not always obvious.
You do not wake up one morning and feel one single exposure.

It accumulates.

Heavy metals accumulate.

Plastics accumulate.

Environmental chemicals accumulate.

Parasites hide. Inflammation builds.

Your energy declines slowly enough that you start calling it "normal."

That is the trap.

You get told your fatigue is just age. Your joint pain is just age. Your brain fog is just stress.
Your blood pressure is just genetics. Your inflammation is just part of getting older.

But what if your body has simply lost the ability to clear what modern life keeps putting in?

That was the question I had to face.

Why You Are Still Toxic After Doing Everything Right

Your body stores toxins in fat cell: heavy metals from your water supply.

Glyphosate and seed oils from your food supply.

Barium and aluminum from the air.

Forever chemicals from packaging.

Microplastics that have entered every tissue category studied.

These are not water-soluble.
They do not leave through normal water sweat.

A conventional sauna heats the air to force a sweat response.

That sweat is mostly water. It cleanses the surface.

It does not mobilize what is stored deep in fatty tissue.

A far infrared sweat is different in composition.

It carries fat-soluble toxins, heavy metals,
and tissue compounds that a heat-only sweat cannot reach.

That is the layer medicine never addressed.
And producing that kind of sweat requires one specific thing:
far infrared energy at the correct wavelength,
delivered to your body at high enough
dose that it drives actual tissue heating — not just surface heat.

"Far Infrared Saunas are the best way to get rid of heavy metals, and the only way to get plastics out of the body."
Dr. Sherry Rogers, M.D. — Author, "Detoxify or Die

In Their Own Words, Relax Sauna Testimonial BookEvery other supplement protocol I ran. Every binder. Every cleanse. They could not do what the right sauna did in 60 days. Dr. Rogers wrote three quarters of her book on the research and benefits of far infrared saunas. She is not alone.

Why Every Wood Sauna I Tested Failed — And It Is Pure Physics

When I ran the comparative analysis, I kept asking the same question: why does one produce a deep sweat at lower ambient temperature while the others require me to sit in 170 degree heat just to perspire? The answer comes down to three compounding losses that every wooden cabinet sauna suffers from. I call this the dose problem.1paragraph

Water vapor absorbs far infrared.

The more you sweat inside a wooden cabinet, the more humid the air becomes, the more far infrared is absorbed by that air before it ever reaches your skin.

The cabinet's own humidity actively works against the therapeutic mechanism.

This is why you sit in 150 to 160 degree heat for 45 minutes just to match what a correctly designed device does at 120 degrees in 15 minutes.

Dose comparison: what actually reaches your bodyWooden Cabinet SaunaEmitter-to-skin distance 24 to 36 inches Interior surface Wood — absorbs 85-95% of FIR

Source: Relax Sauna Buyer Guide and Comparative Analysis Study.

The irradiance figures reflect measured data at 20 cm.

The Relax Sauna delivers 3 times the irradiance of mixed infrared saunas and 4 times that of Amazon near-infrared saunas at the same distance.

The tent is not a design compromise.

A wooden cabinet is the wrong shape for far infrared therapy.

The wood absorbs the FIR before it reaches you.

The distance compounds the loss.

The humid air absorbs more.

These are physics, not preferences.

The reflective tent design is engineered around exactly these problems.

Almost 90 percent of the emitter's output reaches your body inside the tent. In a wooden cabinet, a tiny fraction does.

The rest heats the walls.

The Reflective Tent Plus 40 Patented Semiconductor Chips.
That Is the Whole Story.

Here is what makes the Relax Sauna different from every other tent sauna I tested. The tent solves the distance and absorption problem. The chips solve the wavelength purity problem. You need both.Most portable saunas use a carbon-coated grid. Electricity heats the grid, which generates light composed of far infrared energy and other wavelengths that are not far infrared. Because the output is not purely far infrared, it does not have the intensity or purity required to drive resonant absorption at the cellular level. These saunas work. They just do not work as fast or as effectively.The Relax Sauna uses 40 patented ceramic semiconductor chips. A computer program is embedded in each chip. It filters out all non-far-infrared wavelengths. The result: over 95 percent of the energy emitted is pure far infrared in the 4 to 14 micron range — the range the human body emits and absorbs most efficiently.How the silver lining worksSilver is embedded into the fabric of the Relax Sauna tent. The far infrared light generated by the two radiators at the base of the tent hits the back of the tent wall and is reflected back toward your body — at the speed of light — bouncing through your body over and over from every angle. You become the dominant absorber in the enclosure instead of the walls. You start feeling warmth within 30 to 60 seconds. Wooden saunas take 20 minutes to produce the same sensation."These semiconductor chips filter out the near infrared and the mid infrared — so you get pure far infrared energy, which is the only frequency that resonates with the water cells in your body."— Rex — verbatim, Relax_Sauna_Rex.docxThe chips are also self-regulating. Unlike carbon panels that require the heater to cycle on and off — giving you uneven hot and cold distribution — the semiconductor chips lower the current when heat runs high and raise it when heat drops low. You sit in a steady, consistent far infrared field. Not a fluctuating one.This is also why the unit is still running after 12 years of daily clinical use in one physician practice. Semiconductor chips do not crack, peel, or oxidize the way carbon ink panels do. The spec on day 1,000 is the same as day 1.

What the Doctors Who Use It Actually Say

This is endorsed by Rex. That carries some weight. But it is also endorsed by people whose credentials I will not try to match."I was the Chief of Medical Operations for the NASA Space Program. I have my own functional integrative practice, Tri-Life Health, with an eight-month waiting list for new patients. The sweating comes faster and it's more a total body experience. With other saunas you have to be in there 20 minutes before you really start sweating. I've tried to take good care of myself. I find that after I exercise, before the sauna, I usually am sweating within five or ten minutes. It's more time efficient. We've seen some major breakthroughs with patients."Dr. Roger Billica, M.D. — Former Chief of Medical Operations, NASA Space Program — In Their Own Words, Relax Sauna Testimonial Book"I think they're one of the most powerful healing tools in this country. It increases the collateral circulation of the heart, increases ATP synthesis. It's fantastic for increasing circulation, for gently detoxifying the body and all kinds of other things."Dr. Nelson Bulmash, M.D. — Relax Sauna Testimonial"What a lot of people don't know is that when we put together our integrative clinic, we have used the Relax Sauna because for the type of sauna, they have double infrared heat sources which allow you to get the patient hotter than most other types of saunas. We have gotten people definitely in the 101.5 to 101.9 fever range — which is really quite hot for a sauna. The Relax Saunas work quite well to get into that level of therapeutic hyperthermia. Please check out Relax Saunas."Dr. Paul Anderson, M.D. — Integrative Medicine Clinician — Relax Sauna Testimonial Materials"I'm a doctor who thinks every house in the country ought to have a far infrared sauna in it. This one is the easiest to use, one of the best ones out there, very effective, very cost effective and it has become very popular in our practice and with our patients. The real breakthrough is with patients that are so toxic, burdened and they don't sweat. When the sweating starts, their phase angle comes up on their mitochondrial function, they feel better. Stuff starts happening."Dr. Roger Billica, M.D. — Tri-Life Health, Fort Collins, CO — In Their Own Words, Relax Sauna Testimonial BookDr. Boz — the ketogenic medicine physician followed by hundreds of thousands of patients — uses it. The LA Dodgers use it. GadgetReview ranked it #1. These are not people who trust marketing. They ran the same test I ran, one way or another, and reached the same conclusion.

What Happened in My First 60 Days

I tracked my own biomarkers the way I test every product I review for GadgetReview. Before and after. No cherry-picking.My blood pressure normalized. My energy came back and stayed there — no 2pm crash. Chronic inflammation decreased. And my heavy metals were measurably reduced at the 60-day mark. That last one is the one that surprised me most. I had been on a full supplement protocol for heavy metals for months with limited movement. Sixty days with the Relax Sauna moved the needle."My blood pressure normalized, my energy sprang back, and my chronic inflammation decreased and it is all due to a mechanism that is unique to Relax: it is the most effective FIR product that drives out the toxins stored deep in our fatty tissues. No other supplement protocol or expensive sauna could accomplish that goal. And no other product on the market comes close at this price."Rex — Co-CEO, GadgetReview.com — Relax_Sauna_Rex.docxI now use the Relax Sauna as the cornerstone of the health protocol I run at High Voltage Human. The stack: Relax Sauna as the primary detox driver, combined with liver, colon, and parasite cleanse. I believe this combination to be the most potent and effective detox protocol available at any price. The sauna is the exit pathway everything else depends on.I am not a paid spokesperson for Relax Sauna. I reviewed it for GadgetReview, called it #1, and then became an ambassador because I could not in good conscience keep recommending it to my readers without making it easier for them to get it.

What the People Who Actually Use It Say. Verbatim.

I have tested hundreds of products. The customer language around this one is different. People do not say it is nice or relaxing. They say things like this:"The infrared sauna lessened my muscle pain by at least 70%. Today I am still med free. No over the counter pain meds either."Dee C. — Judge.me verified review"I had been waking up in the middle of the night and could not go back to sleep. After 2 treatments in the sauna, my night's sleep was amazing and now I feel rested when I wake in the morning."James S. — Judge.me verified review"It has hardly been two weeks since I have had the silver Elite Sauna, and my finger joints are no longer stiff or painful. My sleep has improved where I sleep a longer stretch of time, and since I am not one who sweats easily, I can sweat in the sauna and release toxins."Yuko — Council Bluffs, IA — Judge.me verified review"Prior to using the sauna I suffered from constant hiccups, yawning, fatigue, and headaches… oxygen saturation was 67%. After 3 weeks of 15-minute daily use, my levels read 100%. I haven't had headaches, fatigue, yawning, or hiccups. I feel amazing."C.G. — Verified customer email"I suffer from fibromyalgia and this sauna has helped me beyond measure… lowers my stress after a day on the road… I sleep better than I have in years… deep sweat that goes beyond the surface… Nothing else at the show compared! My nephew with multiple back surgeries could touch his toes after using it."M.P. — Ohio — Event testimonial"I'm a practitioner of holistic medicine (and soon an M.D.). I had excruciating shoulder pain that no therapy could reach. After 7–8 minutes in the infrared sauna, my pain was gone — and it's still gone. The infrared penetrates deeply where no hands can. Immediate results!"R.B. — Pennsylvania — Practitioner"Five weeks of consistent use: I lost weight, sleep much better, and a large fatty lipoma reduced by about two-thirds. Your FIR sauna is an integral part of my health regime."D.S. — Texas — Customer email"My first was a $5,400 cedar unit that took 45 minutes to heat and left me drained. I researched and chose Relax because it turns on blasting heat instantly — full heat in under 2 minutes. No bells and whistles, but I feel energized after and later in the day too."Talia Schube — Amazon review. Switched from a $5,400 cedar sauna."If you are debating between a Sunlighten wooden sauna and this, get this."Anneka S. — Amazon review

Still Deciding? Fair Questions.

How fast will I notice a difference?Most people feel different after session one. Deeper results — improved sleep, reduced joint stiffness, measurable biomarker changes — typically appear within two to four weeks of daily use. Yuko reported her finger joints were no longer stiff in under two weeks. James S. had two sessions before his night-waking stopped. My own heavy metal markers shifted measurably at 60 days.Is it too late for me to see results?My biomarkers were in the red for blood sugar, cognitive function, and heart health before I started. C.G.'s oxygen saturation was at 67 percent. The mechanism does not care how long you have been accumulating toxins. It starts working in the first session. The sweating is the signal.How do I use it? How long per session?15 to 30 minutes. Full heat in under 2 minutes. Full sweat by 8 to 12 minutes. I do it first thing in the morning. David S.B. calls it better than a cup of coffee. Maria and her husband go 20 to 30 minutes every night. Their electric bill went up a few dollars.Why does it look like a tent?Because the tent is not a compromise. It is the engineering solution. The reflective silver lining bounces far infrared back at your body from every angle. The emitters sit 6 to 12 inches from your skin instead of 2 feet away. Close distance, reflective surface, filtered wavelength. That is what produces the dose. The wood is cosmetic. The chips and the tent are the product. I overlooked this for three years because I judged it on looks. That was a mistake.What is the return policy?30 days, no questions asked. If you do not feel a meaningful difference in your energy, sleep, or pain levels in the first month, return it for a full refund. The product earns its own trust. This is just the backup.

If You Have Done Everything and Something Is Still Missing

This might be the thing you have been walking past. I walked past it for three years at every health expo I attended. Fellow practitioners I respected had one and I did not ask them about it. When I finally tested it, it was #1 out of six. My biomarkers confirmed what I felt. I am not going to tell you it is for everyone. I am going to say the 30-day trial exists for a reason — use it.Shop the Relax Sauna — $100 Off TodayFree shipping available. 30-day risk-free trial.
