It took 10 years (from 1987 to 1997) for the Relax Sauna company in Taiwan to discover an Advanced Technology, using Semiconductors

These semiconductor chips emit Pure Far Infrared Energy between 4-14 microns. We sent the Relax Sauna to California Polytechnic State University, in August, 2022. They own a bolometer, a sophisticated device measuring frequency emitted. Their studies indicate that the Relax Sauna radiators consistently for 60 minutes, emitted far Infrared energy between 7-14 microns. Water is a far infrared molecule with a wavelength of 8 microns, and we, as humans, emit 9.4 Microns.

The Relax Sauna is probably the best and only realistic option

To do hyperthermic heat stress training at home

"Replicate the benefits found in (far infrared sauna) studies, and actually exceeded these results. “Do not waste your time with sub $500 units on Amazon.” “I would have loved to have come here and said the $250 Amazon model is great and we can all enjoy the benefits of heat stress daily at home with a low bar of entry yet, I believe that the Relax Sauna is the cheapest viable option.”

“I would recommend Sauna training and The Relax Sauna unit in particular to anyone (especially paired with cold showers). It seems to have such wide ranging benefits. I made a post here giving my thoughts on a more systematic way to evaluate saunas for home use and quantify heat stress training and citing some existing research comparing dry, wet, and infrared saunas. I also noted the sub $300 portable IR sauna I bought on Amazon was a dismal failure, as was a new higher end one for $500. After my intense disappointment I started to research the more expensive but seemingly reputable brands in this category. After Ordering the Relax Sauna, I was still skeptical. But as you'll see below, the results exceeded my expectations greatly.”

“I'm thoroughly impressed with this unit, the Relax Sauna, and even more amazed as I write this up and am comparing my numbers to those in the studies. It's even more impressive it was able to accomplish all this even with my head out. I turned on the sauna at at 2 minutes this thing had reached the 100F mark (rather than 30 minutes in the cheap sauna). At 10-12 minutes I was sweating. After 20 minutes the air temp reached a really surprising 165F. Final reading was around 169F at 25 minutes!”

“The internal biometrics are even more exciting! My starting body temp this time was 98.4F. At 25 minutes my temp rose to 101.1F! If you read my previous post this handily beats both the IR and 176F dry Finnish sauna used in the study. Second, my heart rate went from 90bpm to 133bpm This is higher than the dry and wet sauna in the other comparison study (+21.2% for wet). By the end this was working my heart equivalent to a moderate cardio workout. Finally, I weighed myself and lost 2lbs (+/- 0.5lbs). This beat the 45 minutes in the dry sauna in the third study. 5 minutes after getting out my body returned back to 98.8F. It's remarkable how quickly it re-established. You can also see my heart rate remained elevated for another 6+ minutes. Subjectively the heat felt great. It was not harsh or uncomfortable at all like many wet and dry saunas I've been in. Head being out is really nice. I could really feel my heart going by 25 minutes.”

I'm crying in joy because the pain is gone!

So glad there are good people.

Oh my gosh, YES! (To the question – “Are you a happy camper?) “If I were a multi-millionaire, I would Give to some people who can’t afford it or something. This belongs in every old folk’s home. It’s made Just an unbelievable difference. I had really bad sciatica. Really Bad. Like 2 months’ worth of sciatica no sleeping. The relief I got was just it made me cry. There were tears of relief and joy. Because I was just mentally drained. I got out, I was literally hopping around. Before, I was walking with a cane … Constant pain for 2 months, … I have been lucky to get a couple of hours of sleep a night. Constant hammering pain. I have tried everything I can to get rid of this pain. This thing is going to save me a fortune. I can do this every frickin day. Kind of a no-brainer. I knew it was going to help, but I had no idea it was going to help this much. I have been in other saunas for pain relief. They work. But this one is pretty damn quick. 10 minutes in there. I felt my pain melt away. I love that it is portable. And they are well-made. Heavy fabric.

Rebecca has been promoting the benefits of Far Infrared Saunas for over 15 years, and how they are essential for optimal health.

Rebecca Harder includes 17 pages on the Relax Sauna and Far Infrared Energy in this resource guide:

Why Far Infrared Saunas are an absolute necessity For Feeling Fabulous?

There are many reasons, but the top two reasons are:

1st, it is absolutely necessary to reach and maintain proper body temperatures (98.6) and using an infrared sauna is the best way to achieve that (along with addressing Thyroid malfunctioning). The second reason why using an infrared sauna is necessary would be: To aid in the detoxification of heavy metals and chemicals.

Rebecca suggests that the Relax Sauna is the Most Therapeutic Sauna!

When someone asks me which Infrared Sauna to get, I ask them what is their purpose, financial and space limitations and most important what is their energy state ? ... However, for people with enough energy, (not perfect energy but enough energy), I recommend a Far Infrared Sauna for the purpose of sweating, and specifically the Relax FIR Sauna over all other ones. Why that one?

“Now I know the Relax Infrared Sauna does not look as impressive as the big wooden box saunas, making it hard to believe that the MOST THERAPEUTIC Sauna is not necessarily the most expensive and nicest looking one. Like the ... that have built in stereos, lighting and that spa like feeling. I understand your gut reaction. For the last 20 years I turned my nose up at the Relax Sauna every time I saw them at the health conferences until 2016 when I tried one.

I was sold on the Relax Sauna within the first 3 minutes! Right away I could feel the difference. No preheating like with the wooden saunas. In the Relax Sauna, I experienced Instant Relaxation. 15-20 minutes produces a profuse sweat, which took 45 minutes to get to a light sweat on my biomat under the mylar shet and that was after it preheated for 20 minutes. Who has time for something to preheat? I don’t have an hour a day for a sauna, but I can sqeeze in 20 minutes for a relax sauna. It was then I realized that most people could afford the Relax Sauna and would do it daily because they would get benefits right away. The wooden box saunas are really pretty but for the $4000 plus price range (and the one I wanted was $6000), I realized the relax sauna was superior because it truly felt amazing and gave better results.”
