Far Infra-Red Saunas by High Tech Health, International

For some time now I have been investigating Far Infrared saunas from different manufacturers.  Some years ago, when I first experienced the wonderful benefits of a Far Infrared Sauna, there were very few available, from only a couple of sources. 

Since then, the benefits have become much more widely known, and consequently there are now a number of sources.  The overall technology has improved and at least some manufacturers have taken advantage of the additional formal research as well as feedback from many people using these units, to improve their designs. 

This is a good thing.  But it also has made it more challenging to choose the right one.  Along with a divergence in technology, there has been a significant spread in pricing.  At the low end, one can find “bargain” Far Infrared Saunas designed for 2 people for around $1,200.00 (in the U.S.).  At the higher end, a two-person Far Infrared Sauna can cost $5,000.00 or more, (also U.S.)

Before I get into specific models and recommendations, let me take moment to explain the difference between conventional saunas and Far Infrared saunas.  Most of us are familiar with conventional saunas.   In those, there is a bed of hot rocks, which radiate the heat to heat up the air in the whole sauna, typically anywhere from 140 degrees Fahrenheit on up to as high as 170.  The air, in turn, heats your body.  In addition, it is customary in many conventional saunas to pour water on the hot rocks, generating steam.  This makes them more effective. 

Many people find conventional saunas quite stressful.  Some do not enjoy trying to breath the hot air.  And I generally do not recommend them for people who are ill. 

In contrast, the Far Infrared sauna works by having emitters, or “Far Infrared heaters”, which generate Far Infrared rays, that penetrate deeply into the body.  These help the body to release toxins, stimulate blood and lymphatic flow, and help muscles to relax.  They do NOT depend on heating the air inside the sauna.  The air gets warm as a side-effect of the emitters, but it does not get hot, nor does it need to.  In fact, many people who do not like the heat at all, leave the door open on their Far Infrared saunas and still get the full benefit. 

Some people have not enjoyed saunas because being in a small, closed room makes them feel uncomfortable.  Since you can even leave the door open in a Far Infrared sauna this is not a problem with them.  In fact some Far Infrared saunas even have  fan so that you get plenty of cool, fresh air as you enjoy your sauna.  This does not seem to detract from the health benefits one bit. 

Until now I have not felt ready to recommend any specific Far Infrared Sauna.  Delving into the engineering of them is truly a complex and involved endeavor.  Quite a bit of physics and advanced cellular and micro biology are involved.

I have finally put enough time and research into this complex subject to feel confident in a recommendation:

I believe that the Far Infrared Sauna line by High Tech Health, International, is an excellent product line that encompasses superb engineering, is well fabricated, and offers some outstanding health features at a reasonable price. 

Their two-person unit at $3,495.00 plus shipping, is in the mid-price range.  But it is clearly in the upper end from a quality and feature standpoint.

The differences in the actual far infra-red heating elements among different manufacturers are quite widespread.  And the resulting differences in health affects can very significant.  The most important health aspect of the heating elements is that they must be designed, fabricated and made from materials that result in an element that does not put out a lot of EMF, which is not good for living things, including human beings.  Without going into the physics, I’ll just say that the heating elements designed and manufactured by High Tech Health, International are done right.  A number of manufacturers use questionable approaches and questionable materials in the manufacturing of their heating elements.  This could create its own set of health risks.  You needn’t worry about this when it comes to the heating elements from High Tech Health. 

An interesting and unique feature of the High Tech Health Far Infra-Red Sauna is that it is constructed from poplar wood.  Almost all others are constructed from cedar wood.  When I asked their engineering staff why they made the choice to use poplar wood, here’s what they told me:  Cedar wood has been a traditional material for both conventional and Far Infrared Saunas for as long as they have been around.  The reason is that cedar is highly rot resistant and weather resistant.  This is desirable in a sauna that is out in the weather, being rained on and fully exposed to the elements.  However, there is a price to be paid for this weather resistance.  The very same organic chemicals that are naturally occurring in the cedar wood and that make it resistant to weather damage also are somewhat toxic to humans, and also more likely to provoke allergenic reactions.  While the toxin is not strong enough to have dramatic effects for most people, it can and does put a load on the immune system, and so at least some of the health benefits are offset for most people. 

With conventional sauna technology there is good reason to locate the sauna as a stand-alone building, or otherwise well isolated from living quarters.  They generate and use a significant amount of conventional heat.  In contrast, Far Infra-Red Saunas use an electrically-generated radiant energy that is very close to light in characteristics.  There is very little actual heat involved.  So there is no need to isolate a Far Infra-Red Sauna from other structures. 

In fact, the very first time I ever used a Far Infra-Red Sauna, it was located in the spare bedroom of the house.  It had been assembled right there, set directly on the carpeted floor of the bedroom, and there was no extra insulation or anything isolating it from the rest of the house.  It did not cause the rest of the house to heat up.  And it was quite convenient as the shower was right next to the spare bedroom.  It turns out that placing Far Infrared Saunas in a spare room, or in a dual-use room, is actually quite common.   Lots of people do this and find it works out very well.

And although some people do place their Far Infrared Saunas outdoors, most are located under a patio roof or other partial protection.  So using cedar is not required.

So why use poplar wood?  Well, I’ve pointed out why cedar may not be such a good choice because of the significant health problems that can result.  Poplar wood is as close to neutral as possible, in terms of allergy factors, as well as other negative health effects.

Overall, I believe that the Far Infra-Red Saunas from High Tech Health, International are excellent, and represent a truly good choice and a good value. I am confident that the health benefits will be more than worth while.

High Tech Health now offers saunas in sizes from 1-person on up to 4-person.   The High Tech Health Far Infrared saunas come as a set of modules that can be easily assembled in less than a half hour.   You can set your sauna up indoors or on a covered patio.  All sizes are 73 1/2″ high.  The 1-person model is 36 1/4″ wide by 36 3/8″ deep; the 2-person model is: 49″ wide by 40 1/2″ deep; the 3-person model is 60 1/2″ wide by 44 1/2″ deep; the 4-person model is 70 1/2″ wide by 49 1/2″ deep.  All but the 4-person model operate on 120 volts or can be special-ordered to operate on 220 volts.  The 4-person model requires a 220 volt circuit. 

We have a High Tech Health Far INfraredsauna, which I use nearly every night.  I know that it is helping me to keep my body as free as possible of toxins.  It feels great to take a nice sauna after a hard workout or a day of hard work.  I find that I recover from whatever the stresses are if I take a sauna.  In short, I love it.  I sleep better after a Far Infrared sauna.  It also boosts the immune system.  (Far Infrared saunas are standard equipment in all of the best German medical clinics.)  If I start to feel a cold coming on, I take 2 Far Infrared saunas a day and I don’t get the cold!  It is one of the best health investments I have ever made.

    What do you know about Sunlighten and Helo saunas
    Many thanks

      Posted May 10, 2012 at 11:18 am | Permalink

      The Sunlighten saunas are excellent. The only drawback to them that I am aware of is that they are expensive. They are elegant and very attractive. In terms of really beautiful detail work, the Sunlightens are great. But they are quite a bit more expensive than the High Tech Saunas and in terms of functionality, EMF, safety and actual health benefits, I do not think they are any better.

      We have a High Tech suana and we love it.

      If you do decide to get a High Tech sauna, let them know that I referred you and you will get a substantial discount.

      To your great health!

    Hi Jeff,

    I read your recommendation on the High Tech Far Infrared Sauna. I am concerned about the EMF output. Did you find any information on that?

    Are you truly a third party, it is hard to wade through everything out there to be able to make an informed decision.

      Posted May 10, 2012 at 11:12 am | Permalink

      Thanks for your inquiry. I am truly an independent party in this. I agree that it is hard to wade through all the “info” out there. Much of it is simply wrong because those providing the supposed info do not understand the basic laws of physics, nor many of the health principles involved. I like to think that I am an exception. I have a strong background in physics, and have been researching and practicing natural and holistic health for over 35 years.

      I really like the High Tech Health saunas. Many of my clients have them. We have one that we frequently use. I did take EMF measurements on them a few years ago. They were very, very low. (Lower than all that I know of other than the Sunlighten Saunas, which also are very good, but which also cost quite a bit more.

      I have a colleague who is a specialist in helping people survey and mitigate EMF and RF. He has a new meter that is even more sensitive than the one that I used. We are scheduling a new survey of my home, which will include the sauna. So I may have new info soon. (Should be within a month.) You can also call High Tech Health. In my experience they have been very honest about answering any questions about the products they offer. And if you tell them that I suggested you call, they will go the extra mile to spend whatever time you need to discuss any concerns. If you decide to purchase a High Tech Health sauna, let them know that I recommended their saunas and you will get a substantial discount from them.

      By the way, High Tech Health also distributes the Akai Water Ionizer. We have one, (again after a great deal of research on my part), and we love it.

      Please feel free to call or e-mail me if I can be of further help in any way.

      To your health!

      Hi David,

      Yes, they are terrific Far InfraRed saunas. After much research and even tryhing several different Far INfRaRed saunas I setting onthe High Tech Health ones as being the best, and a really good value, as well. We have had one for several years and we love it. You buy them directlky from High Tech Health. http://www.hightechhealth.com – 800.794.5355 Best to call them. They carry 2 different sauna lines. Both are great, but I think the Thermal Life ones represent a better value and they are somewhat less expensive. If you call them and tell them I referred you, they will give you a $300 discount!

      Please let me know if you have any questions about them or if there are other health matters that I can help you with.

      To your great health!

    Hi Fredericka, Yes, this is off-topic, but no big deal. In the future, for web site questions, please feel free to just e-mail me directly: jeff@MyHealthOptimizer.com Now to your question: I am actually using the blog features that are built into the WordPress theme that I am using, which is Thematic. However, I have very extensively modified the theme by some custom coding. One of the unusual features of my site is that it actually supports two blogs that are on the same site, but that are independent. The blog under the “Resources” TAB is for reviewing health products and resources. The blog under the Health Blog Tab is completely separate. That was a real tricky thing to get working.

    I did have to get some help from a professional web developer with this: http://www.liquidwebsite.com. We modified the master CSS that controls the look, feel and layout of the site. IN essence, we copied the child theme that controls the blog in the Thematic template for WordPress. Then modified the copied child theme so that it would not conflict with the original child theme. I am not a web developer. I am a holistic health researcher and practitioner. So it did require the help of a friend, who does that sort of work for a living.

    I have two new web site developments I am working on: 1. I want to implement some sort of forum, but that may be awhile. I am concerned about the amount of time it could take to monitor and administrate it. 2. I am working on a special, “cancer info page”, called “Cancer Keys”. That will have some information about preventing and getting rid of cancer. I do not want to just hang that information out there for anyone who wants it. The problem is that cancer is a very tricky beast, and I think it is very important for people to work with someone who has real experience when they are dealing with cancer. And it seems important for people to have a certain level of prerequisite background knowledge in order to be able to realistically evaluate cancer information. So I ma creating a set of qualifying questions that visitors will need to properly answer in order to be given access to the information under the “Cancer Keys” TAB. So that is what I am working on next, web site wise.

    By the way, your site is already awesome! I love what you are doing. The site is beautiful and what you are doing is inspiring. You may be interested to know that after I dropped out of medical school because I felt that their approach was mostly not my idea of how to achieve good health, maintain good health and help people who were ill to recover, I went back into building and structural engineering, which I learned about from my Dad while growing up. Long ago I built quite a few different types of buildings. and I have always been interested in both bamboo and in strawbale building. IN fact, it has long been a dream of mine to build a strawbale structure to house my holistic health clinic. Maybe some day I will be able to actually do it. Meanwhile, please keep up the great work, yourself! Let me know if I can be of further help.

    To your great health!

    Hello Fellow Health Enthusiasts,

    Several people have recently asked me what time of day it is best to take a Far InfraRed Sauna. That is a great question. If you ask different “experts” you will get different answers. So I will just share what I do. I prioritize as follows: First, I want to make sure that I do take a Far InfraRed Sauna once a day if possible. So because my schedule is often packed full and not always as predictable as I wish, I often end up just squeezing in a Far InfraRed Sauna when I can. Sometimes if I know that I will be out late seeing clients, or presenting a health workshop, or for some other reason, I take my sauna in the morning before I start work. Basically, I just do what I can to work it into my day.

    That said, my favorite time to take my Far InfraRed Sauna is shortly before I go to bed. It really helps me to get a much better night’s sleep. I find that I go to sleep more easily and quickly, and I tend to stay asleep for longer and to rest more deeply as I sleep. I generally wake up feeling more rested and ready to meet the new day if I have taken my Far InfraRed Sauna before bed time.

    My second favorite time to take my Far InfraRed Sauna is immediately after a workout. It feels great after a hard bicycle ride, or one of my grueling martial arts workouts that I love to do. It just great after any experience like that, when I am still dripping with sweat, to jump into the sauna. And I think my recovery is actually faster when I can do that.

    For those who might want to know, here is my favorite evening ritual: I take my Far InfraRed Sauna a little while before I am ready for bed. I have worked my way up so that setting our Far InfraRed Sauna to 130 degrees, letting it preheat for about 10 minutes, then sitting in it for 20 to 25 minutes feels about right for me. When I come out of the sauna I do a little bit of gentle stretching to take advantage of my muscles being looser than usual. (Tighter than optimal muscles is one of my ongoing health challenges.) Then I shower. Next I either apply some Ancient Minerals Magnesium Gel to my lower legs or I soak my lower legs, from about 3 inches below my knees on down in a bath of warm, filtered water with Ancient Minerals Magnesium Bath Salts dissolved in the water. I either soak for 20 minutes, or I leave the magnesium gel on for 20 minutes. While I am either soaking or just sitting quietly with the gel on my legs, waiting for the magnesium to absorb, I have the lights turned low and some quiet, soothing music on. It is sort of an end-of-day informal meditation. Sometimes I just daydream. Other times I may review parts of my day, and think of things to be grateful for, or perhaps things I want to use as inspiration for my dreams or even for the next day. But I am careful to do this without stress or any forced focus.

    When about 20 minutes are up, I wipe down my legs and go to bed. This seems to work great.

    I do not recommend taking a Far InfraRed Sauna more than once a day. I think you really get all the benefit that the Far InfraRed Sauna has to offer by taking one a day. Doing it more frequently may actually impose just enough stress so that it begins to offset the benefits. This is so even thought the Far InfraRed Sauna is the most gentle type of sauna available.

    The bottom line is that the Far InfraRed Sauna is healing, is a great aid to detoxifying the body and for stimulating the immune system. These are all benefits that anyone can use. So I do my best to take a sauna every day. That said, given the realities of my schedule, I usually end up missing about 1 day a week. When that happens, I don’t sweat it, (pun definitely intended!). I know I can look forward to a rejuvenating Far InfraRed Sauna the next day.

    I hope this is helpful. Please post your sauna questions, comments or suggestions here.

    To your great health!

    Thanks for your kind words. Your blog layout is really nice. Some of the posts appear to be in Portuguese? Unfortunately, my linguistic skills are found wanting. So I am not able to understand that portion of the content, but again, the layout is very nice. It is innovative and pleasing in terms of look and feel. In fact, one of the things I really like about it is that it makes the comments portion look more a forum, so that those posting comments probably feel more like “members” than like “visitors”. That is a really nice element.

    • Jeff Bell
      Posted May 29, 2013 at 8:26 pm | Permalink

      Hi Taylor,

      Yes, the benefits of Far InfraRed Saunas can be wonderful. That is provided they are the right type, well engineered and properly made. We have one that we use on a frequent basis and we love it. In fact we have the same one reviewed in this post. And even though it is one of the more reasonably-priced good quality Far InfraRed saunas available, it is still more than some can afford. I do understand that. There are plenty of health measures I would like to adopt that I have not, so far, simply because they are beyond our budget.

      Of course, there are many other natural health measures that could help; you. However, I cannot provide a blanket recommendation. I would have to know more about you, your overall health, your health background, and so on. If you spend much time on this site you will notice that I write extensively about the basic principles of health that I have found to be safe and effective and that I think people need to know about. But I stop short of giving specific advice to people dealing with specific conditions because I mostly do not know the details of what they are dealing with. So such advice would not be helpful and may not even be safe.

      When it comes to health, the “one-size-fits-all” approach does not usually work well. There is simply too much variation among human beings for “generic” measures to be good for most. So if you want to go to the “Get Started” page on this site, you could fill in the information requested and submit your input. That gets the ball rolling for you to have a complimentary consultation with me. That is where specific recommendations will be possible.

      I hope my response is helpful.

      To your great health!

    Thank you for your kind words. I do my best. I am very fortunate that I have a strong background in the basic sciences and that gives me access to a number of tools that those without that background simply do not have. I also work really hard at trying to communicate as clearly as possible. That is a real challenge for me so I end up spending a lot of time trying to make sure that my writing is as precise and well thought out as I can make it. I wish I were better at the writing side of this work.

    As far as popularity goes, I need to be a bit careful. My methods often radically differ from those that are accepted and have become the standards of conventional medicine. And they often take a dim view of anyone who questions how they do things, especially if one is getting good results. So, to some extent, my low profile is deliberate.

    Thanks again!

    Hi Jeanett,

    Thanks for letting me know. I struggle with trying to stay compatible with all of the browsers that are out there. When I started, there were only a few browsers that were in common use. Now I can think of at least 10 that are in common use. And they all render pages differently. With some, the differences are slight. With others they are significant. I do not have the resources to make my site work perfectly with all browsers. IN fact, that is nearly impossible, since there are conflicting programming requirements. So I do my best to make it work as well as possible with the majority of browsers. And for the others, in most cases the rendering problems are slight enough so that the content can still be read. That said, if you let me know what operating system you are running and also what version of Internet Explorer you are using, I will do my best to address the issues.

    Thanks again!

    Hi Jeff — Thank you for your postings about FIR saunas and regarding Thermal Life saunas in particular. It is getting harder and harder to compare saunas these days with so many manufacturers out there and now with carbon heaters. Have you had the chance to compare carbon heaters against the more traditional types that HTH uses? I know that HTH heaters are somewhat unusual in that I believe they are sand filled or something similar. The carbon folks say the old style heaters are old and not as good and the folks like HTH are saying the carbons are cheap and not good enough. :) And I must ask, you do not have any investment in HTH in any way in that you are paid to promote them? It is very very hard to find reviews of saunas online that are not on websites that in reality are mouthpieces for the different manufacturers. Very frustrating for a consumer trying to get unbiased info. Thanks for your time!

    I recently purchased a HTH FIR sauna. When I used my triflex meter to measure EMF, the rating inside while on is very very high. Is there a good EMF and a bad EMF? When I contacted them they told me my meter must be faulty but I used it throughout my house and it seemed consistent when appliances were off, on and the power of appliance matching the levels. Could you please shed some light on this? Also if the heaters they use “bioresonance” are the healthy EMF? Like the sun? Thx

      Hi Barbara, I am surprised that you get high EMF readings. We have a Far Infra-Red Sauna from High Tech Health, which we have had for years. And I did measure it, using several very expensive and sophisticated meters that a friend and colleague has for his work, which is helping people clean up the EMF and related energy signatures of their living and work spaces. Our readings came out very low.

      That said, there are different frequencies and different mixes of frequencies. The same it true for wave forms. And to make this whole issue even more complex, living beings are different and react differently to different frequencies, wave forms and combinations. So one could certainly say that some forms of EMF are really harmful and others may not be. But that is one complex rabbit hole to dive down.

      Do you know about amplitude scales? They can be tricky to interpret. So it is not always obvious how strong the EMF really is. The user guide for your meter should help with that.

      How do you feel when you use the sauna? Good, bad, or????

      If you call High Tech Health again to discuss further, which I think is a good idea, see if you can speak with Carmen Burgess, who is one of the most knowledgeable people on the staff. Please let me know who this goes for you.

    I feel good after taking in a session, I’m trying to get one in every day but it’s probably every other that it actually happens. I’m u to 130 degrees for 30 minutes but I don’t start sweating until about 20 minutes in. I’ve communicated with Emily at HTH and she feels my meter is not reflective of actual reading. I’m just nervous. Maybe I will reach out to Carmen Burgess. I’ve been told the owner is an Engineer and that these saunas are mfg’d to the highest degree of health benefits possible. Tx for your response.

      Most likely Emily is correct. Taking accurate EMF measurements can be pretty complex. And obtaining instruments that reflect the elements of EMF that affect health, let alone being able to measure and then assess what the health affects and risks are likely to be gets really complex. For example, the specialist engineer who came to our home and my office to do our measurements brought about $50,000 worth of equipment and measuring instruments with him. This was after I tried to do it myself with about $1,000 worth of instruments and realized that I was getting inconsistent results. (I also have an engineering background, but not the expertise or equipment to do this accurately and get meaningful results.)

      One other comment, the way that far infra-red sauna technology works for health is different than conventional saunas. It is not necessarily the case that higher temperatures correlate with more health benefits. I usually pre-heat our sauna for about 10 minutes. Then I re-start my session right before I get in. I stay in for about 25 minutes, and it gets up to about 120 degrees. I have trying going hotter and longer and it does not seem to improve the health results that I have been able to notice. In fact, there comes a time when it may actually lead to fatigue if you go to far.

    So you feel it is safe to use my sauna for 30 min sessions daily at 120 degrees despite my Triflex giving me a high reading? I can understand where meter quality and reading levels could get tricky. What made me nervous was that Emily stated that they used a Triflex at the facility and they got low readings, so I was just concerned that maybe my sauna had an electrical gliche or something. Mine is brand new and although all reviews stated that HTH saunas were very low EMF , most were written some time ago. I can’t help but wonder if something has changed in the manufacuring process in recent days that is causing mine to read so high.

      Well, I obviously cannot know for sure what is going on with your specific sauna. I have been around a lot of the High Tech Health saunas, and we have had one for a number of years. I have tested a lot of them with good instruments. And I have never seen high EMF readings. But unless I brought known instruments, that had been recently calibrated, and took proper measurements, I would have no way to know what is going on with your specific sauna. It is always possible that there is something wrong with it. I would talk further with High Tech Health. Again, I think Carmen Burgess is the best person to talk with. Maybe you can send them your Triflex and let them measure some of their saunas with it and compare the readings to those they get with their Triflex meters. That way you would at least know if your Triflex is accurately calibrated and if it is reading reliably. That might be a good next step. Also take pictures to show them where you are taking the readings and how so that they can replicate with one of their in-house saunas.

      I hope that helps.

    Hi Estela,

    Thanks for your kind words. I do try to share the best information I learn as I learn it. We are all in this together – trying to improve everyone’s health and help each other to live the best lives we can.

    And it looks like you might be a Kangen distributor? We have been using ionized water for about 8 years. We love it. And we have had a Kangen D501 for almost a year now. (Our previous ionizer was very good and the Kangen D501 is better, so much so that my wife became a dealer for the Kangen Water Ionizers and for the Kangen Ukon Sigma turmeric formula which is amazing.) I will be posting reviews of both in the near future.

    To your great health!

    Hi Jeff,

    Is the $300 discount still offered if I order a sauna and mention your name? I saw that posted back in 2013.

    Also, what’s the difference between the Transcend saunas and the Thermal Life saunas?

    Thank you.

    • Jeff Bell
      Posted September 8, 2015 at 10:45 pm | Permalink

      Yes the discount is still offered. Just let High Tech Health know that I, Jeff Bell, referred you. In fact, the Transcend saunas are also from High Tech Health, and they will offer a discount on them, as well. I am not sure the discount amount for those. They are more luxurious and expensive saunas.

      Both lines are excellent and very healthy. As I mentioned, the Transcend line is the real high-end line. They are beautiful and very fine. But either are very good. We have had ours for about 8 years and love it.

    We have a TL-2 Thermal Life Sauna and the control panel is acting wacky. It doesn’t stay at a certain temp, switching from a high number to low number and the sauna does not heat up. I called Carmen and she suggested to unplug it and restart it in 30 minutes. That worked the first time, but it does not work again. Carmen said the sauna did not have a replacement part b/c of it being an older model. Do you know of any websites that sell replacements for Thermal Life. It’s a shame to have to ditch it. It looks brand new and in excellent condition otherwise.

    Thanks for your quick response Jeff. The sauna was bought in 2004 or 2006. I would have to look or call High Tech Health for the invoice. My question to you was do you know how to get replacement parts for a control panel. I was told they do not carry replacement parts for the model I have because of the year we bought it. If there is another route you can suggest I take, please don’t hesitate to let me know. Like I said, everything on the sauna is in excellent condition. The control panel, where you select the heat and minutes is not working correctly.

      Posted October 16, 2015 at 5:02 pm | Permalink

      Hi Charlie,

      Unfortunately, I have not done a whole lot better than you did in trying to find a solution. I will say that failures in any part of the Thermal Life saunas is rare. We have had ours for about 8 years and use it an average of 5 times a week. And I have lots of colleagues and clients who have similar histories with them. So I am dismayed that yours has failed and that replacement parts are not readily available.

      I did talk with one of the principles at High Tech Health to brainstorm and see if there was anything we could come up with to help you. She confirmed that replacement control panels are not available for saunas that old. We went back to the actual manufacturer and confirmed this.

      Here is an option that may be worth considering: There are still a few “electrical repair artists” in various locations who have the skills to diagnose and fix things like this. People with these skills are becoming increasingly scarce, but there are still a few. (More and more, when electronic gadgets fail we recycle them instead of fixing them as that is usually the only economical choice.) If you can get in touch with a person with the right skills, let me know and I will do what I can to get you the schematic for your control panel. They will need that to repair it. This may sound like a long shot. But I think it feasible enough so that I would try it.

      If you want to proceed, please try to find the serial number for your sauna and e-mail that to me. I will then see if I can get you the schematic so that you can move forward.

      To your great health!

    Hi Jeff, can you explain the difference and benefits between far infrared and near infrared technology? Thanks!

    • Jeff Bell
      Posted October 21, 2015 at 10:33 pm | Permalink

      Hi Carmen,

      Thanks for a great question. This is actually a rather deep rabbit hole we can dive down. So let me try and cover the essentials.

      First a bit of background: Infrared energy is a form of light. However, it is outside of the normal, human visual spectrum. Like all radiant energy, light, visible and not, it is characterized by wave lengths and frequencies. Infrared light is radiant light energy that is just beyond the normal human visual range. On a spectrum chart it would be right next to the visual range, and it even overlaps to some extent as there are some humans who can see the parts of the infrared range that are right next to the “normal” visual range.

      Infrared light is generally divided into 3 sub-categories: near infrared, mid-infrared and far infrared. The near infrared is right next to the normal visual range. Next comes the mid-infrared, and at the opposite or far end of the light spectrum, away from the visual range, is the far infrared.

      For years, it has been known that infrared radiant energy has health benefits. the energy penetrates well below the surface of the skin and stimulate circulation, promotes the release of toxins so they can be eliminated and stimulates healthy neurological function, as well as helping to suppress pathogens.

      There is and has been a long running and lively debate over which form of infrared provides the most health benefits, near infrared, mid infrared and far infrared. To be sure, there are differences and for specific health conditions they likely have some relevance. The earliest infrared saunas that I know of were all far infrared. Then some began to be made that were near infrared. I am not aware of any that are mid infrared. The latest “innovation” in these saunas is to use “full spectrum” infrared. These have infrared emitters that generate and disperse infrared energy that covers the entire infrared spectrum, from near, to mid to far.

      However, when it comes to choosing a sauna I think focusing on the type of infrared may be the wrong question. All of the infrared types provide significant benefits. so the real question is which of the infrared saunas are designed so that they are very low EMF. In other words, which ones use emitters and overall electrical and electronic technology that does not subject the user to “dirty electricity” or the harmful radiant energy caused by dirty electricity.

      I come back to the saunas from High Tech Health when I ask that question. They are very low EMF and a great deal of attention has been put on making them so. As a result you get the health benefits without and of the potential downsides that come with saunas where that special design and engineering focus is lacking.

      There also is one downside to the near infrared saunas I have checked: Near infrared energy does not disperse through an area as well as far infrared energy does. As a result, to get the full benefit of most near infrared saunas, one needs to shift their body position quite frequently so that all parts of the body get treated. In contrast, a well designed far infrared sauna does not require such movement. I can sit quite still in mine, or even lie down in it for the entire session and still get the full benefit.

      To your great health!

        Posted November 2, 2015 at 9:25 pm | Permalink


        I am sorry to hear that. In general, I would recommend a Far Infra Red sauna as part of your efforts to get well. But I would have to know more about your specific situation to really know for sure how much good it is likely to do. And there are lots and lots of other measures that I would add to your overall program. Maybe you are already doing them. But it would be good to check.

        If you can e-mail me your contact information we can set up a call on Skype to explore what makes the most sense for you.

        In the meantime, if you do want a sauna, I stick with my recommendation for the High Tech Health saunas. They are made from chemically neutral woods, which is critically important. They are reasonably priced, and the Far Infra Red emitters are very carefully engineered and made so that they do not put out significant harmful radiation. Lots of others on the market, quite frankly blow it in both those areas.

        I did check with High Tech Health and confirmed that they can ship to the U.K. (They also can ship to Australia and New Zealand! – Far out!) It is a bit expensive to ship to any of those locations, but their base prices for these high quality saunas are so low compared to any competing saunas that it is likely still worth it. If you call High Tech and let them know I referred you, they will give you a good discount, as well.

        To your great health!

    I have basically the same question as the previous poster about the differences between the NIR and FIR saunas. Sauna Space has NIR saunas stating there are no EMF from the Tungsten lamps and that FIR saunas provide no phototherapy which is highly beneficial to the cells in the body and is provided in NIR. The Sproutman, who sadly was recently killed in a car crash was using Ozone in a seated zip up sauna. Have you researched the effective differences between the different saunas?
    Thank you. Your insights are greatly appreciated.

    • Jeff Bell
      Posted November 2, 2015 at 11:03 pm | Permalink

      Hi Bobbi,

      Great question. I have done a lot of research on Infra Red saunas, comparing the different types of Infra Red, which are differentiated by wave length, (which also corresponds inversely with frequency). The physics involved gets complicated pretty quickly. So I will stick with the bottom line here – how it affects health.

      Far Infra Red and Near Infra Red can provide significant health benefits. And even the middle range of Infra Red provides benefits. Some of the latest offerings are called “Full Spectrum Infra Red”, which also provide benefits.

      All entail a form of light energy that is outside the usual human range of visible light. This light energy penetrates surprisingly deeply beyond the skin and into the body, where is stimulates a detox process, increases circulation, and reduces inflammation. There are other benefits, as well, but those are the most obvious ones.

      Now, let us compare Far Infra Red and Near Infra Red: Both provide health benefits. The biggest obvious problem with Near Infra Red is that it can cause cataracts! So I would not use it under any circumstances. Another problem is that the Near Infra Red systems that I have seen do not disperse the energy well throughout whatever enclosure the bulbs or emitters are in. As a result, anyone using a Near Infra Red sauna needs to constantly change their body position in order to treat all areas. And many of the Near Infra Red systems use various forms of plastic enclosures. I doubt they are safe and healthy, particularly as the temperature goes up.

      Lastly, a lot of the Near Infra Red sauna systems do not enclose the head, so it does not get the treatment.

      We have a High Tech Health Far Infra Red sauna, and have had it and used it for nearly a decade. We LOVE it and would not trade it for anything.

      The wood is neutral, (poplar), the emitters are so low in terms of EMFS that my good scientific instruments cannot measure them. I’m sure there are other good saunas out there, but they are mostly have problems or are much more expensive.

      One more thing: I would NEVER combine ozone and Far Infra Red at the same time. We have and use both, but I would not feel safe combining them. I can’t find any studies to support doing that, nor to convince me that it is safe. So we do them separately.

      To your great health!

    Hey Jeff,
    Any luck with getting the schematic for the sauna I have.

    • Jeff Bell
      Posted November 2, 2015 at 9:38 pm | Permalink

      Hi Charlie,

      Thanks for your patience. I have invested quite a bit of time to try to track down a schematic, but have not found one available. There are logical reasons for this. Given today’s world of global economics, the control panels are made in China, even going back that far. And this is pretty much true for all the Far Infra Red saunas I have looked into, no matter who the maker is. Making the control units in the U.S. would make the saunas too expensive. And the suppliers and factories in China change from time-to-time. So tracking down a schematic is not something that I was able to do, nor is High Tech Health.

      However, I spoke with the founder of High Tech Health, Bill Johnson, and pitched your case to him. He said that if you called and asked for him, he would talk with you and propose a very special way for you to get a replacement sauna. When you call, you will not get him directly, but it you let the staff member who answers you call know that he asked you to ask for him, they will let him know and he will either get on the call or return your call. I hope this works out for you. Please keep me posted. The number is: (800) 794-5355.

      Also, I suppose you might find a really bold wizard of electronic repair who would attempt to repair the control panel without the schematic. But that is a long shot, and there is no guarantee it would succeed. I am a pretty good soldering iron jockey and I would not attempt it. So I do think replacing the sauna and taking advantage of Bill’s offer is the best choice.

      By the way, I have looked into the warranties from other saunas, and none that I could find are actually over 5 years. For example, one prominent maker advertises a “lifetime warranty”, but when you look at the fine print, they indicate that it is for the life of the sauna, not the life of the owner. I am not sure what that means in practical terms, but I doubt it would cover this.

      I hope I have been of some help.

      To your great health!

      OK. Good luck for a good outcome. By the way, do you know what date you actually purchased your sauna? And are you the original owner? It doesn’t really matter. I am just curious since this is the first High Tech Health sauna that I know of that has failed. I’m sure there are others, but this is the first that I know of.

      Hi Stephanie,

      This is a great question that comes up often. I most recently addressed it in the comments section for this blog post on November 2, 2015. Here is an excerpt of my response, which I believe explains my view on near infra red vs far infra red and the so-called “full spectrum” saunas that are being marketed. (I am providing an excerpt because I also deal with other issues in my response. But you can go to my reply, dated 11/2/2015 if you want to read the entire reply.)

      “… I have done a lot of research on Infra Red saunas, comparing the different types of Infra Red, which are differentiated by wave length, (which also corresponds inversely with frequency).

      To me the risk of cataracts seals the deal. I would never knowingly do something to expose myself to that risk. And it would be the height of irony to go to significant lengths to adopt a practice or technology to improve my health if it actually risked significant damage to my eyes. Makes no sense to me. And the information about the cataract risk that near infra red imposes is well documented and well-known. So I cannot understand why anyone with an ounce of integrity is even marketing this dangerous technology. That makes no sense to me. I hope they will come around to the view that integrity is more important than making money.

    Just wanted to touch base with you concerning our sauna that had problems with the control panel, and because of the date of the sauna, High Tech Health did not have replacement parts. After contacting Bill Johnson, as you suggested, he gave us a nice discount on purchasing the same unit, but with updated wiring. We are going through our budget to see if we can take advantage of the discount. So thank you for helping us through this issue.

      I am happy to share my methods, as well as the resources for doing your own, at home ozone regimen. However, this thread is about Far Infra Red saunas.

    I am excited to report the electrical engineer,tennis buddy of my husbands came over this morning and was able to pinpoint the problem with the sauna! He said it was a ribbon cable connecting the switch plate on the control box back to the circuit board. When he disconnects the ribbon cable on the outside panel the sauna works. So if you ever find a ribbon cable for the switch plate we could use it! He disconnected the outside cable and by using just the plate on the inside it heats up, timer works and light!
    BTW I emailed about ozone, hope you rec’d it. Please let me know if you didn’t, you have my email to respond with it though. Thank you!

      Hi Charlie,

      This is great news! Thanks for the update. If you contact Bill Johnson and tell him you just need that ribbon cable, he should be able to help. Otherwise, because ribbon cables and their connectors are pretty standard, your engineer friend should be able to find one for you on the Internet or at an electronics supply store and take care of it that way. At the very least, you can count the number of rows and pins, then buy the connectors and a short length of ribbon. It is pretty easy to crimp on the end connectors. I have made a lot of these over the years for my various medical devices and for research apparatus. You can even find services on line that if given the specs will make up a ribbon cable to your specs. I’m sure your engineer friend can give you the detailed specs that you need.

      I don’t think I got your e-mail about ozone. Can you please re-send it? Thanks!

      I am surprised and sorry to hear that you have had a bad experience with High Tech Health. I have been using and recommending their products for more than 12 years and have never had a bad experience. I have never found them to be less than honest and forthright. I have never had a client who has complained, either. So this is a surprise.

      If something has gone wrong for you in working with them, I would love the details. Please e-mail me the details to: webadmin@myhealthoptimizer.com I will call the founder and do whatever it takes to straighten things out. Again, I have found them to be very reasonable, honest and fair. So I am sure that if made aware of an issue, they will do anything within reason to resolve it.

      To your great health!

    Hi. Thanks for the very good information about this far infrared sauna and about far infrared saunas and their health benefits, in general.

    I have two questions:

    1. I see that a lot of the newer far infrared saunas have built in wireless technology and even Bluetooth capability. Is this safe?

    2. There seem to be some far infrared saunas on the market now that use heat lamps instead of the low-EMF carbon emitters that you describe. Are these as effective and are they safe?

    Thanks for any guidance you can provide.

      Hi Darci,

      Thanks for your kind words and for 2 really great questions. Here are my responses:

      1. I would NEVER consider using a sauna of any kind that had built-in wireless or Bluetooth technology. Honestly, I cannot understand why any sauna designer or manufacturer would even consider including such technology in any health device that is primarily intended to detoxify the body and promote overall health. The evidence that exposure to most forms of wireless technology, including Bluetooth is extremely harmful to health and that the effects are serious and cumulative is overwhelming. So, right off the top I would not trust the integrity of any sauna manufacturer who included such dangerous technology in their saunas. Nor would I want to put my body in a sauna that included such technology. To me it is as absurd as installing an expensive water filter system in your home to make the drinking water healthy, and then using lead pipes to distribute the water. It makes no sense at all.

      In case you are not fully aware of how dangerous wireless technology and EMF really is, I can refer you to another blog post that goes into that in depth: http://myhealthoptimizer.com/the-serious-toxin-you-cant-see-electro-magnetic-pollution/

      2. I am not a fan of using heat lamps to generate and distribute the far infrared energy that results in the health benefits. There are several problems with this approach: You do not have a lot of control over the characteristics of the far infrared energy when it is generated by heat lamps. You cannot really control the temperature very well. Nor is it easy to control the intensity. Further, and perhaps more importantly, most of the heat lamps used to generate far infrared also emit a significant amount of near infrared energy or light. Exposure to this form of energy over time has been shown to cause cataracts. Not good! In contrast, properly designed far infrared emitters are very low EMF and they generate and emit just the right frequency to detoxify the body without adding stressors to the body’s biological systems. We have had and used our High Tech Health far infrared sauna for more than 8 years. We still love it!

      Also, keep in mind that only neutral woods should be used to make the cabinet part of a far infrared sauna. Woods that contain “aggressive chemistry” to resist heat, insect damage, etc. are actually chemically toxic. These include redwood, western cedar and Canadian hemlock, just to name a few. In contrast, both poplar and alder are woods that are considered “chemically neutral” and therefore ideal for use in constructing a far infrared sauna.

      I hope my response has been helpful.

      To your great health!

    I have ms and use a far infrared sauna bag, it it like a sleeping bag. I never sweat though it gets hot. I do 30 min sessions. Is this the right sauna for me?

      Hi Paula,

      I would have to know more about the specific sauna bag that you are using. What is is made of? How is the far infrared energy generated and distributed, does your head fit inside the bag while you are using it, etc.

      How long have you been using it? Have you noticed any improvements in your condition since using the sauna?

      As you can see, there are a lot of considerations. I would have to talk with you before I could offer any more specific advice. I have helped a number of people with MS to significantly improve. A few are even completely symptom-free. I encourage you to send me an e-mail so we can get to some details. That will enable me to help you much more effectively than just trying to answer general questions. My e-mail address is easy to find on this site.

      To your great health!

      Hi Chris,

      Thanks for your comment. I must respectfully disagree. How did you conduct the measurements of the energy spectrum and magnitude? Do you have professional level instruments? Do you have the proper background and training to properly make these measurements? It is a lot more complex than most people think.

      As far as Sunlighten goes, I did look at them. I could not recommend them because their EMF levels were too high when I did my review. I know they have corrected that since. At the time their saunas also were are made from non-neutral woods. I have not looked at them again for a few years. However, they are still quite a bit more expensive than the High Tech Saunas, which I believe are excellent. We still have one and use it frequently. We love it.

      To your great health!

    Brian Richards, founder of Sauna Space Pocket (NIR) Sauna makes a convincing case that NIR doesn’t cause cataracts. See https://saunaspace.com/debunk-near-infrared-light-cataract-connection/
    But assuming he is wrong, another NIR manufacturer offers protective glasses specifically for NIR.
    Do you think they would mitigate the risk?
    Incidentally, I had an unpleasant experience with Sunlighten. The sales rep was extremely aggressive and badmouthed competitors nonstop (and incorrectly I might add). Also, I checked a job hunting website and turnover is very high and most of the employees HATE working there.
    My doc says I have to start a detox program asap, but this is the most frustrating purchase decision I’ve ever had to make!

      Hi Shiela,

      Thanks for your comment and for posting several really good questions here.

      I am not sure what to make of Brian Richards’ contention that Near Infra Red energy does not promote cataracts. The research required to determine this definitively would be extensive – beyond my means and likely beyond the means of most organizations.

      In answer to your question of the goggles: They might sufficiently mitigate the risks. I suppose it depends on how well they fit, how strong the near infra red energy is, and other variables. But then, I would not want to purchase a sauna that required me to wear goggles in order to use it safely.

      I understand how challenging it can be to find the right one for you. I can help you with that. Please feel free to contact me. I have a few standard questions I can offer. That will lead you to the choice of a sauna that will best meet your needs.

      To your great health!

    Hi, I am from Australia and thinking about buying a 10 year old second hand High Tech Sauna. Could anyone please tell me if I can buy spare parts here in Australia for the Sauna if ever I need to in the future. Thanks

      Hi Mandy,

      If the sauna is 10 years old, I highly doubt that parts are still available. So if it is in really good condition and you can get it at a really good price, it may make sense. Otherwise, it is a gamble.

      To your great health!

    How much would an older High Tech 2 person sauna cost approximately cost.

      Hi Barbara,

      I am not sure what you are asking. Are you asking what a used sauna should cost or be worth? If so, I cannot answer that. It depends on the condition, who is selling it, how old it is, etc. Frankly, I have not seen very many used High Tech Health saunas for sale. I think this is because most people who buy them are very happy with them and do not sell them.

      If you mean a new sauna, but an older model, I am still not sure what you are referring to. High Tech Health still markets two lines of saunas: the first line was their Thermal Life saunas with are excellent, but not quite as fancy and available at a lower price. The higher end line of saunas is their Transcend line. Both lines are great. I still recommend either. Honestly, I think the main differences are cosmetic.

      If you are interested in a sauna, (we love our Thermal Life sauna from High Tech Health, which we have had for many years), call High Tech Health and they can give you the details, answer any questions you may have, and provide current pricing. If you let them know that you are a referral from My Health Optimizer, they will give you a substantial discount. Their web site it: http://www.HighTechHealth.com and the number to reach them is: (800) 794-5355.

      To your great health,

    Who knew it would be so complicated to decide which infrared sauna to get? That makes me even more happy to have found your page here, and I appreciate all your great insight!

    I’m wondering if the discount you reference is still available through High Tech Health? It looks like they’ve got a wider variety of saunas since you first wrote this blog. We have room for a 1-person sauna, and would love any recommendations you may have.

      Hi Christine,

      Yes, there is a lot to know. I wish that ALL far infrared sauna makers and sellers would only use woods that are chemically neutral and would do whatever they needed to in order to ensure that the far infrared emitters are low EMF. That would make it a lot easier. In the meantime, here is the best answer I can give you:

      I still stand behind High Tech Health. In my opinion, and based on my own research, including testing, measuring EMF levels and related research, I remain confident that the far infrared saunas from High Tech Health are the most reasonably-priced ones that meet the best health criteria.

      Yes, they still offer a special referral discount if you let them know that were referred by My Health Optimizer.

      High Tech Health carries 2 lines of far infrared saunas: They are the Thermal Life line and the Transcend line. Both are great from a health point of view. The Thermal Life line is the lower cost of the two lines. The only real difference that I can see is in the area of aesthetics and appearance. The wood joinery and the craftsmanship are better in the Transcend line, but those saunas also are more expensive. Again, from a health point of view, I don’t see any real difference.

      To your great health!
