Hello everybody and
Rob:welcome to the vP life podcast
Rob:brought to you by vitalityPRO.
Rob:My name's Rob and I'll be your host on today's episode.
Rob:Today we're sitting down with Johannes Kettelhodt from Clearlight Saunas.
Rob:Johannes, an engineer by training, is the CEO and distributor of Clearlight
Rob:in the UK, the EU and Australasia.
Rob:Today's episode really covers everything you've likely ever wanted to know
Rob:about sauna, and Johannes and I discuss what makes infrared saunas unique,
Rob:why they're potentially a healthier option for you than traditional
Rob:saunas, how they work in the body, the famous Niacin protocol for heavy
Rob:metal detoxification, and so much more.
Rob:As usual, all the links to this episode will be available in the show notes, which
Rob:you can find in the description below.
Rob:Then, I'd like to ask you a favor.
Rob:Our little podcast is slowly gaining traction, and we'd love
Rob:it if you could leave us a review wherever you listen to podcasts.
Rob:This will help us grow, reach more people and allow us to host future guests.
Rob:And with that, on with the show.
Rob:Hi, Johannes.
Rob:Thanks for joining us today.
Rob:Well, this is going to be a podcast, obviously about sauna.
Rob:Would you care to introduce yourself quickly?
Rob:Just tell us a bit about Clearlight and your backstory.
Johannes:Sure.
Johannes:Uh, thanks for having me, Rob.
Johannes:Uh, G'day everyone.
Johannes:My name's Johannes.
Johannes:I'm one of the two CEOs of
Johannes:Clearlight Saunas International.
Johannes:Um, Yeah, as the name indicates, uh, Clearlight Saunas is a sauna brand.
Johannes:It's not any traditional one, but it's an infrared sauna brand.
Johannes:Been around for approximately 25 years.
Johannes:And I think I've really taken, uh, the biohacking health community in a storm.
Johannes:Um, you know, some of our.
Johannes:Ambassadors or, um, spokespeople are the likes of Ben Greenfield, Dr.
Johannes:Josh Axe, and a few other international athletes and medical doctors.
Johannes:And I think the true reason on why Clearlight really championed the
Johannes:infrared sauna popularity in that health and wellness space is the fact that
Johannes:they come with an outstanding quality or a build of outstanding quality.
Johannes:And we issue a lifetime warranty, um, from a health perspective,
Johannes:it's a true low EMF and ELF sauna.
Johannes:I'm sure we'll dive deeper into what exactly that means.
Johannes:And we use Medical grade heaters that we sort of invented ourselves to really
Johannes:raise the core temperature effectively.
Johannes:For those who don't know an infrared sauna.
Johannes:Um, works using infrared heating panels as opposed to hot air.
Johannes:Um, and I'm sure we'll sort of dive into the mechanics, um, off that a
Johannes:little bit further down the track.
Johannes:Um, my background is, uh, engineering.
Johannes:So I sort of didn't really, you know, didn't wake up one day or had the
Johannes:vision to actually become a wellness entrepreneur, but, um, instead,
Johannes:uh, yeah, I'd really enjoy it, uh, breaking down complex topics around
Johannes:technology, um, into day to day
Johannes:. Bites for people to apply.
Johannes:Always been fairly health conscious, ran a marathon, did
Johannes:elite sports at a very young age.
Johannes:And actually realized quite quickly that, you know, if I look after my temple,
Johannes:my body, my soul world, and I tend to have more energy on the output level.
Johannes:Um, and that sort of all, you know, led to, I think me being open, uh, around
Johannes:opportunities and health and wellness.
Johannes:And then when I was 23, we sort of jumped on and, um, yeah, sort of
Johannes:internationalized Clearlight and, um,
Johannes:now we're sort of working on another brand.
Johannes:For a few different products.
Johannes:Um, but ultimately that's my, uh, brief story.
Rob:What about sauna specifically attracted you to
Rob:it as a health entrepreneur?
Rob:Obviously you, you could have gone down the, uh, the sort of the cold, the
Rob:cold route, you could have, uh, gone down the red light route specifically.
Rob:What was it about sauna that really attracted you to it?
Johannes:Yeah.
Johannes:It's a good question.
Johannes:I mean, I think we can all agree that saunas over the last
Johannes:specifically five years, uh, have gained a lot of popularity.
Johannes:Yeah.
Johannes:You know, I think COVID definitely accelerated that and, and I feel
Johannes:very similar fashion, uh, or trend happening with cold plunges at
Johannes:the moment, or in general, like, you know, cold water exposure.
Johannes:But when we started, this was the year 2013, like, you know,
Johannes:I barely knew infrared saunas.
Johannes:I only knew saunas from my childhood and I was born and raised in Germany.
Johannes:Uh, there's a very strong sauna culture, not to be compared with
Johannes:Finland, but it's definitely, it's probably second or third, uh, you know,
Johannes:rank when it comes to sauna culture.
Johannes:So as kids, we used to go out on weekends or even, you know, sometimes during
Johannes:the week as the whole family into like a public sauna space, we'd, you know,
Johannes:take a few different sauna sessions.
Johannes:So, you know, I personally, Really got used to heat
Johannes:mechanisms at a very young age.
Johannes:Um, and I think then when I sort of saw this opportunity, I was like,
Johannes:well, you know, let's actually look a little bit deeper into, you know,
Johannes:what are the mechanistic, well, what mechanisms are there for soreness?
Johannes:Um, and it literally was a whole different universe that opened up.
Johannes:Um, you know, back then, yeah, there was little evidence around it, but, you know,
Johannes:we kind of saw the first studies and the first, um, endorsements come through.
Johannes:Uh, and that's essentially what we said, well, you know, this is a great product.
Johannes:Uh, it's a great driver for longevity and heat and specifically
Johannes:in the infrared sauna field.
Johannes:There were hardly any companies that had really gone internationally, uh, and
Johannes:that really had a very strong promise.
Johannes:Around health, you know, that was actually the time when infrared
Johannes:saunas per se were really high in EMF.
Johannes:The industry didn't know better.
Johannes:There were a ton of different old clunky, very hot heaters around that actually made
Johannes:it very uncomfortable to stay in at times.
Johannes:But I think Clearlight really had pioneered low EMF technology.
Johannes:And we were like, holy, holy hell, like this is a gem.
Johannes:Like, you know, the world needs to hear about this.
Johannes:Um, so I think it's a mixture of, you know, being at the right time
Johannes:at the, at the right location, and I think having that cultural heritage
Johannes:around saunas and heat exposure.
Rob:Fair enough.
Rob:Yeah.
Rob:Um, you've mentioned infrared and, uh, EMF and ELF, uh, a few times now.
Rob:Um, what is, what, what defines an infrared sauna?
Rob:I mean, as you know, the work Rhonda Patrick's done specifically around saunas,
Rob:uh, where she sort of seems to sort of, Be more interested in dry saunas,
Rob:mainly for the increased heat output.
Rob:Um, but what makes an infrared and an infrared sauna and sort of how
Rob:does it benefit, um, not benefit, how does it compare to say a dry sauna
Rob:or your more traditional steam room?
Johannes:Yeah, I mean, I think to really understand it, I think we have to quickly
Johannes:recap on what a traditional sauna is.
Johannes:A traditional sauna, uh, you know, has been around for centuries
Johannes:and utilizes hot air, uh, as a primary mechanism, um, of heat.
Johannes:So typically you would have one, uh, stove and a sauna, uh, and you
Johannes:know, over time you would achieve air temperatures of say 60, 70, degrees,
Johannes:depending on how hot you like it.
Johannes:And you'd have an outburst.
Johannes:Which is, you know, literally put hot water on the stone and you, you know,
Johannes:that would essentially create, uh, steam.
Johannes:Um, and yeah, it would be cranking hot.
Johannes:Uh, you would do two or three rounds, you know, five to 20 minutes, sometimes
Johannes:even 25, which I find unimaginable.
Johannes:It's just so freaking hot.
Johannes:And, you know, that you, you know, I mean, in between you take time, you
Johannes:know, down times, you take a cold shower, and then you just literally relax.
Johannes:And, you know, the whole protocol, if you do it properly, probably
Johannes:takes you two or three hours.
Johannes:And it's, I genuinely think it's one of the best feelings in the world coming out
Johannes:of two or three rounds of steam sauna.
Johannes:And I think the reason why Rhonda Patrick, um, and you know, some of the
Johannes:other health professionals, um, are very fond of traditional saunas is that
Johannes:they've been around for much longer and therefore have been studied a lot more
Johannes:in depth compared to infrared saunas.
Johannes:Infrared has only been really invented, or has been identified, I think in the
Johannes:1800s by Herschel, um, Um, and then in 1976 or something, I think they
Johannes:created the first sort of infrared heater, um, which then actually made
Johannes:up an infrared sauna for that on the, uh, for that on the time in Japan.
Johannes:So this whole technology is only 40 years old, but the good thing
Johannes:is that infrared can be found.
Johannes:pretty much everywhere in nature.
Johannes:So infrared is part of the invisible light spectrum.
Johannes:It also refers to electromagnetic frequency or energy.
Johannes:You have different types of infrared.
Johannes:You have near, middle, and far infrared.
Johannes:They all vary in terms of the wavelength or the spectrums, the
Johannes:penetration depth into the skin, and some of the unique benefits.
Johannes:But the bottom line is This light is being absorbed or it penetrates into
Johannes:our skin over time, our core temperature goes up because obviously our body
Johannes:needs to deal with that influx of heat.
Johannes:Um, we start breaking a sweat, um, and then we literally
Johannes:get a cardiovascular workout.
Johannes:And so, you know, in terms of sweating and infrared, it's one actually
Johannes:helps you as well to sweat profusely.
Johannes:In fact, I would probably, And really intense and good infrared sauna.
Johannes:If you do it for 45 to 50 minutes, it's going to help you sweat more
Johannes:than a traditional sauna because you're staying in there for longer.
Johannes:Right.
Johannes:So I sort of spoke about these two or three rounds of a traditional
Johannes:sauna and an infrared sauna, you do a minimum of 20 minutes, um, up to your
Johannes:maximum of 45 or 50 minutes, if you can stand it, um, and our research
Johannes:and other research has essentially shown that during this, uh, this Time.
Johannes:Um, your core temperature can raise, um, for up to 1.
Johannes:6 and 1.
Johannes:5 degrees Celsius.
Johannes:Which is 38.
Johannes:4, 38.
Johannes:5 degrees Celsius, depending on where you measure it.
Johannes:So that is a proper fever.
Johannes:Like if you woke up one day and you'd have 38.
Johannes:5 core temperature, you would stay at home in bed because you realize your
Johannes:body is sort of going through something and you need to, you know, you need to
Johannes:take rest and, and an infrared sauna and heat stress in general helps us
Johannes:go through a similar mechanism and.
Johannes:Yeah, so therefore I do think they're alike in some ways, but obviously the way
Johannes:that heat is generated, the way he uses solar is different, and the scientific
Johannes:evidence is also much different.
Johannes:Traditional saunas have been around for longer, they are better studied,
Johannes:there are more studies on that.
Johannes:But infrared saunas are catching up in terms of a popularity.
Johannes:And I'd love to, you know, sort of shed some light on that as well down the track.
Johannes:Um, but also in terms of medical and scientific research papers that are coming
Johannes:out, there's a ton of benefits about them.
Johannes:I've seen the first doctors and, and, you know, very active biohackers and
Johannes:social media that are not just, um, sort of wellness gurus, but also, you know,
Johannes:have a medical or scientific background.
Johannes:Actually speaking up about the fact that they believe infrared saunas
Johannes:are more superior than traditional.
Johannes:I think all of that is yet to be determined because to my knowledge,
Johannes:there's not a single study that has really compared whether one
Johannes:or the other is more beneficial.
Rob:So in a sense, infrared saunas are sort of heating the
Rob:core almost as a microwave would, essentially, in a very rough sense.
Rob:With a lot of, uh, cheaper infrared saunas, uh, you tend to see that
Rob:they don't come with these warnings about, uh, these ideas of EMF and ELF.
Rob:Can you sort of just touch on that briefly and why it's so important to
Rob:have a infrared sauna that carries low EMF and low ELF, uh, ratings?
Johannes:Yeah, 100%.
Johannes:I think it's a very important topic.
Johannes:EMF stands for Electromagnetic Frequencies.
Johannes:ELF stands for Extremely Low Frequencies.
Johannes:And then you have a different type of frequency, which we find in our day to day
Johannes:lives, which is, uh, radio frequencies.
Johannes:Uh, Bluetooth and wifi for those that are new to this topic, I'm sure you guys all
Johannes:understand that sleeping on a wifi router wouldn't be beneficial for your health.
Johannes:I mean, I'm sure everyone understands that these devices give off some sort
Johannes:of frequency that carries information.
Johannes:And there's a similar analogy when it comes to EMF and ELF.
Johannes:Um, if you think about an electric occurrence, and that
Johannes:could literally be your computer that you're charging right now.
Johannes:There is electricity running through the cable into the device whenever we
Johannes:have electricity from minus and plus or however you want to exchange these poles.
Johannes:You have an invisible electromagnetic field building up
Johannes:around the cable or wherever the electric current runs through.
Johannes:The stronger the electricity consumption or the stronger the s in there are, the,
Johannes:the stronger the electromagnetic field is.
Johannes:So that's the, the, the bottom line.
Johannes:You know, this is measured at millis.
Johannes:You have another frequency that is called extremely low frequencies,
Johannes:that's measured in volt per square centimeter or square meter, depending
Johannes:on how you want to calculate it.
Johannes:And again, it's a, it's an invisible field of electromagnetic frequencies
Johannes:or energy sort of surrounding wherever electricity runs through.
Johannes:And this has been studied extensively, particularly over the last 10 to 15 years.
Johannes:And there's a lot of research and evidence coming out that High exposure
Johannes:to these types of frequencies is potentially harmful for a human body.
Johannes:Some of the, uh, health risks are around dementia, around,
Johannes:uh, insomnia, around fatigue.
Johannes:You mentioned brain fog, brain fog when we spoke yesterday.
Johannes:I know for a fact that in Germany, um, electro or hyper, uh, electro
Johannes:sensitivity is now actually Uh, consider a disease in Germany.
Johannes:So if someone has actually had for years and an artificially high exposure
Johannes:to these types of frequencies, they literally get brain fog and fright
Johannes:and they feel dizzy and can't work.
Johannes:And we see that on a day to day basis.
Johannes:Now, you know, you might have heard about the potential, potentially harmful
Johannes:benefits of airports, where if you have your phone, you know, on your, on your
Johannes:ear for a long time, there are some scans that, and I think even the World Health
Johannes:Organization has actually raised concerns about the, um, artificial exposure
Johannes:of, uh, high concentrations of EMF.
Johannes:In some situations, I think it's unavoidable.
Johannes:We work in a public space, you know, there is naturally a higher exposure to
Johannes:EMF, but this is particularly concerning when you speak about an infrared sauna.
Johannes:Why an infrared sauna?
Johannes:Because you have many different infrared heating elements built into the cabin.
Johannes:It could be a cabin of two times two meters, or a meter by one meter, and you
Johannes:have, say, 10 different heaters in there.
Johannes:And each of these heaters It obviously needs to run with electricity.
Johannes:So that's why you have a lot of EMF exposure fields around it and
Johannes:particularly cheaper, but not only cheaper, even, you know, you find
Johannes:some infrared sort of companies that actually don't know or don't care.
Johannes:Um, EMF exposure particularly is an issue.
Johannes:And if you think about the fact of why people might invest in an infrared
Johannes:sauna, well, it's to obviously, you know.
Johannes:Do something good for the health, you know, de stress, uh, help down,
Johannes:help regulate the nervous system.
Johannes:You know, maybe they have a health issue that they want to combat.
Johannes:And obviously if you sit in this cabin and you're literally getting
Johannes:fried by this EMF and ELF because the company didn't tell you, or you
Johannes:didn't know, um, you might actually potentially be causing yourself more
Johannes:harm, than actually doing good for you.
Johannes:And that's why this topic is so important.
Johannes:Um, and this is why I think, you know, we really tried to educate
Johannes:on the different frequencies.
Johannes:What could be done about it?
Johannes:What is a typical threshold that you really need to ask the manufacturer on?
Johannes:And yeah, it's, it's shocking because I'd probably say 90 percent of the
Johannes:companies out there don't care.
Rob:Yeah.
Rob:No, I've, I've just looked it up while you were, while you were speaking.
Rob:It's now, uh, EMF is now considered a class to be, uh, carcinogen by
Rob:the world health organization.
Rob:Uh, so it is sort of gaining traction as to how the sort of non
Rob:native, uh, frequencies are actually dangerous for the human body.
Rob:Uh, mechanistically, uh, just coming from, from, from our side, uh, what they
Rob:do is they seem to disrupt the cell quite a lot and they can actually damage a
Rob:number of enzymes, including pop enzymes.
Rob:So.
Rob:Stop their function, which are involved in DNA repair and DNA replication.
Rob:So, um, yeah, and I know Andrew Huberman has also talked about the dangers of EMF.
Rob:Uh, although mentioned, although they were rat studies, um, high doses of
Rob:these non native frequencies again around, uh, rat testicles resulted in.
Rob:The rat's becoming basically hypergonadal, um, so that seems to be more related to
Rob:the fact that it was directly heating up the testes and, um, damaging, uh,
Rob:and damaging the testicles so that they weren't actually able to produce,
Rob:uh, testosterone as well as sperm.
Rob:But yeah, it would, it is, it could probably lead us to a whole
Rob:conversation about grounding and I'm sure you've, you've, uh, absolutely.
Rob:Yeah, you've looked at Clint Ober's work specifically around this, but
Rob:yeah, human body does not need any more inflammation or any more dysregulated,
Rob:uh, movement of calcium into cells.
Rob:So yeah, it's especially important.
Rob:And, uh, I think, well, I know that one way to mitigate that is to increase
Rob:your, uh, magnesium, um, intake, um, high amounts of EMF exposure can.
Rob:basically open gaseous calcium channels and allow excess calcium into the
Rob:cell, which is an excitatory molecule and can create cellular damage.
Rob:And basic biochemistry dictates that calcium and magnesium work in tandem.
Rob:So the more magnesium you have, the less calcium within a cell you
Rob:have, essentially, in a nutshell.
Rob:So that's definitely one way around it, although it's just a
Rob:patch and not really a solution.
Rob:And it's arguably one of the, uh, The reasons why we as a society have
Rob:such low magnesium levels, aside from the fact that there's just a dearth
Rob:of magnesium in the food supply.
Rob:Um, yeah, no, it's, it's incredibly important and not just something
Rob:that should be obviously talked about just in the, In the realm of saunas,
Rob:but yeah, I think that's perfect, uh, to wrap that point up there.
Rob:I suppose the last thing I'd like to discuss with regards to
Rob:clearlight specifically is just, is just the red light panels that
Rob:you can buy as add on attachments.
Rob:And would you sort of just like to quickly touch on that, uh, and why clearlight
Rob:sort of offers this, this option?
Rob:I think you're just about the only people in the industry who do.
Johannes:Yeah, at least at an adequate output.
Johannes:Um, yeah, I'd love to.
Johannes:I mean, I think, you know, our vision has always been to create a space
Johannes:that really allows, um, you know, healing or or sort of wellness benefits
Johannes:to the, to the person using it.
Johannes:And, you know, I think we can all observe, uh, with friends, family, or
Johannes:ourselves that it feels like we have less and less time on a day to day basis.
Johannes:You know, there's more and more work, responsibilities, uh,
Johannes:stress that essentially all contributes to that overall feeling.
Johannes:And the consequences, I think that we tend to oftentimes not prioritize
Johannes:our wellbeing as we'd like.
Johannes:I can observe that with, you know, in my own day to day as well.
Johannes:And coming back to that, you know, we'd sort of really start at.
Johannes:Thinking about how can we maximize the benefit of the Clearlight
Johannes:sauna users when they really have an hour that they can set aside?
Johannes:And you know, with sauna use, it really comes down to the frequency.
Johannes:Ideally, you really want to do it, you know, three, four, five, six times a week.
Johannes:You know, some of the research has indicated that, you know, the more
Johannes:you use it, you know, the sort of the better the health benefits.
Johannes:And it's.
Johannes:Significant numbers in terms of what, you know, very frequent sauna or
Johannes:heat exposure does to your overall longevity and health and altogether.
Johannes:When we come back to this, you know, if we, our dream scenario
Johannes:would obviously be that a person uses the sauna an hour a day, you
Johannes:know, 15 to 20 minutes per heating time, 40 to 45 minutes of using it.
Johannes:Um, you know, during the sauna, uh, you could listen to a podcast, you could
Johannes:do a meditation, you could read a book, you know, because you have much lower
Johannes:temperatures, you don't have the steam, um, so therefore it's perfectly safe
Johannes:to take potentially even a phone in there for a little bit of time, which
Johannes:we don't recommend, but you could.
Johannes:And then we sort of wondered, well, you know, we got the infrared heat,
Johannes:we got sound, we, you know, we sort of have the space, what other health
Johannes:amenities can we actually bring in there?
Johannes:And that's essentially when we sort of started thinking along the
Johannes:lines of, well, you know, wouldn't red light therapy be actually be
Johannes:a great add on to fit in there?
Johannes:Red Light Therapy is also the FDA class two approved technology.
Johannes:I think it's very well known, um, in the health and wellness space.
Johannes:It's been very well studied all together with, I think, multiple
Johannes:of thousand studies on the various different health benefits.
Johannes:Um, and that's essentially when it, you know, we had it on our
Johannes:radar and we figured out a way to integrate it into the sauna.
Johannes:Now this is easier said than done because in a sauna you tend to
Johannes:have, uh, environments of 60, 65 degrees Celsius at times.
Johannes:Yeah.
Johannes:Yeah.
Johannes:And for those that know red light therapy, they often use fans to cool the LEDs
Johannes:that dictates the lifespan of an LED.
Johannes:And that's essentially where the engineering challenge really was and
Johannes:figuring, well, how can we do that?
Johannes:And also, how can we build a device so that the LED intensity doesn't
Johannes:deteriorate due to the heat over time?
Johannes:And that's, I think, three or four years ago, we launched
Johannes:the red light therapy add on.
Johannes:It's a very intense unit that is literally attached to the door.
Johannes:Uh, and then you can obviously, while you're still in there, you can
Johannes:also turn on the red light therapy tower for say 10, 15, 20 minutes.
Johannes:And, and really make sure that your mitochondria get a
Johannes:little bit of boost through the photobiomodulation effect as well.
Johannes:We also have our assault therapy, so you can also integrate an inhaler.
Johannes:We're working on an aromatherapy.
Johannes:And I think the dream to come true, which we've been working on for a number of
Johannes:years would be a UVB or vitamin D light.
Johannes:Cause obviously I know you're in Northern England, I'm in
Johannes:at the moment, I'm in Germany.
Johannes:There is a chronic lack of light at this time of the year, particularly,
Johannes:um, you know, intense UV light in order to make sure that our vitamin D levels
Johannes:are, are okay or where they should be.
Johannes:And I just really think thinking along those lines of how we can
Johannes:stack these different amenities in a useful way to maximize the
Johannes:value for the user in the sauna.
Johannes:It's a very worthwhile task on our end.
Johannes:And, you know, we've been working a lot on this.
Rob:Perfect.
Rob:And those red lights, I assume that they sort of cover a, a wide range
Rob:of wavelengths, sort of all the way, your sort of 600 all the way up to
Rob:about 900 nanometers, is that correct?
Johannes:Yeah, exactly.
Johannes:So you kind of wanna be in the 600 to 660, 670, and then 800 to 860, 870.
Johannes:Right.
Johannes:So red light, near and red separately.
Johannes:Um, but obviously in the infrared solar, we use a very wide spectrum.
Johannes:You know, we have full spectrum heaters in there that combine
Johannes:near, middle, and far infrared.
Johannes:We have red light in the roof.
Johannes:We have far infrared heaters with a very broad spectrum,
Johannes:um, sort of all around you.
Johannes:And I think that's truly what makes the red light therapy another worthwhile
Johannes:purchase because you, as you said, like, you really need those two generic
Johannes:wavelengths at a very high intensity, you know, and, and I think there are some
Johannes:companies that claim, Oh, we got red light in our sauna, but it's not intense enough.
Johannes:Like, you know, I think it really needs to be more than a hundred milliwatts per
Johannes:square centimeter, obviously, depending on the distance of where you use it.
Johannes:And that's not an easy thing to achieve, you know, just putting in
Johannes:red light strips won't do the trick.
Rob:And I'm sure it's, yeah, somewhat of a logistical
Rob:nightmare, at least to start with.
Rob:It doesn't sound like something I'd like to try and really have a go at.
Rob:Anyway, should we, uh, sort of touch on some of the benefits
Rob:of, well, maybe not benefits.
Rob:We've already sort of gone through those, but some of the
Rob:more targeted, um, use cases.
Rob:I know.
Rob:I'm sure you've had a lot of people come to you with certain sorts of,
Rob:uh, well, medical, medical challenges, should we say, opposed to complaints,
Rob:um, generally speaking, where, where do you find people or what sort of
Rob:issues do you find people have the most relief from sauna, uh, from in general?
Johannes:I think the biggest one is stress, you know, by far, and,
Johannes:and potentially linked to that sleep quality and sleep duration.
Johannes:Um, it could obviously rattle on about these, you know, these, these
Johannes:are cardiovascular disease and other lifestyle related diseases.
Johannes:Which we'll talk about, sure.
Johannes:But I think the biggest one, which is hard to quantify is stress.
Johannes:Um, you know, I think the fact that people always say, well, if I've
Johannes:had my sauna, you know, just before I go to bed, I feel so much better.
Johannes:Um, you know, I sleep a lot better.
Johannes:Um, I feel more balanced.
Johannes:My skin looks better.
Johannes:So just really seems to be this overall mood and confidence shifter.
Johannes:And I think a big part of that is the regulation of our nervous system.
Johannes:You know, I think it's very, very easy nowadays to be in that
Johannes:constant fight or flight mode.
Johannes:You know, we get a lot of work stress, emotional stress, financial stress.
Johannes:And I think if we spend the last two hours before getting to bed on a phone or having
Johannes:to work or, you know, just dealing with some of these stresses, I think that,
Johannes:you know, truly has an effect on our nervous system and on our sleep quality.
Johannes:And I think the great thing about the sauna is it's literally a sauna, right?
Johannes:So you walk in there, ideally you don't take your phone, no one
Johannes:technically can get hold of you.
Johannes:And it really helps you come into that, you know, parasympathetic nervous system
Johannes:state to really actually wind down.
Johannes:And actually, you know, and I think along those lines, saunas have
Johannes:been shown to increase melatonin.
Johannes:You know, people don't fully understand yet whether it's really the heat
Johannes:mechanism or whether it's literally through the relaxation and through the
Johannes:down regulation of the nervous system.
Johannes:But I think that's a big one.
Johannes:Um, another big one, I think, which is kind of linked to stress
Johannes:is really cardiovascular health and cardiovascular diseases.
Johannes:Obviously depends, uh, on, on how soon someone gets onto that.
Johannes:But I think we can all agree that cardiovascular disease is a major,
Johannes:uh, driver nowadays for mortalities.
Johannes:So to speak, we have blood pressure, chronically high blood pressure,
Johannes:which seems to be linked to stress, but also other conditions.
Johannes:Our strokes, we have heart attacks.
Johannes:Um, and I think if we really can actually proactively work on allowing us to de
Johannes:stress, allowing our cardiovascular system to get that workout, you know,
Johannes:as long as have been shown in the long term to help regulate blood pressure,
Johannes:um, especially high blood pressure.
Johannes:Uh, I think that is a major driver when it comes to overall health because I
Johannes:don't know the numbers for the UK, but I believe it's kind of around 50 or 60
Johannes:percent where essentially cardiovascular diseases or issues are linked to, to
Johannes:death, to all the deaths reported.
Johannes:And I think for some countries, it's even higher, such as the US or Australia.
Johannes:I think a really, really important one is detoxification.
Johannes:Um, I know we, you know, you know, we both have a passion for that obviously, and I'd
Johannes:love to hear your, your take on the kind of normal pathways of, of a human body.
Johannes:But for a long time, it was believed that the internal organs are the
Johannes:main drivers for detoxification.
Johannes:That is true to quite an extent, which I'm sure you'll talk about.
Johannes:But I think in some studies around 2014, it was also shown that sweating
Johannes:and our skin is potentially another major driver for the detoxification.
Johannes:And, you know, it really depends on the substances and on, on the, you
Johannes:know, on what we want to detoxify from.
Johannes:Um, but sweat has been shown to be more effective when it comes
Johannes:to certain heavy metals, such as cadmium, arsen, um, aluminium.
Johannes:Um, but also PCS and PCBs, um, which is sort of more micro
Johannes:plastics, uh, in lay terms.
Johannes:But you know, it's, you can't generalize the fact that, you know, sweating
Johannes:is more effective than our internal detox, detoxification pathways.
Johannes:Um, but there is a lot of evidence around, you know, infrared
Johannes:saunas supporting your detox.
Johannes:You know, it all comes down to the, uh, you know, toxins
Johannes:being stored in our fat cells.
Johannes:I think you spoke about the lap lipolysis, I think yesterday.
Rob:Lipolysis.
Johannes:Yeah, lipolysis.
Johannes:Thank you.
Johannes:But ultimately, you know, there are infrared saunas have really shown
Johannes:to help, you know, flush some of these toxins out there, protocols
Johannes:around, for instance, detox protocol.
Johannes:And I know you have a lot more in depth understanding when it comes
Johannes:to the biochemical or biochem Yeah.
Johannes:Biochemistry, uh, inside the body.
Johannes:So probably hand over to you for a few minutes.
Rob:Cool, yeah.
Rob:So, what sauna does really well, among other things, is it sort of,
Rob:as you know, it activates, it creates a state of hormesis, which is a
Rob:cellular stress response in the body.
Rob:And when that stress response is activated by the body, it activates
Rob:a certain pathway called NRF2.
Rob:And NRF2 is, uh, responsible for the creation of, of glutathione,
Rob:which is the body's main, sort of, main antioxidant, among many.
Rob:But what glutathione does is, is it allows the body to help, in layman's terms,
Rob:excrete a lot of these substances that are stored, um, in the, in the body.
Rob:However, whilst glutathione is great at sort of getting rid of a lot of these,
Rob:these toxins, It's not able to always liberate them, which is where things like
Rob:the niacin protocol come into their own.
Rob:So.
Rob:What high dose niacin does is it helps to activate lipolysis or the liberation
Rob:of free fatty acids in the bloodstream.
Rob:And as you know, toxins are really stored in fat, especially fat soluble ones.
Rob:So, yeah, the idea with the niacin detox protocol is that you build up
Rob:to a high dose of niacin over time.
Rob:Um, it, it's not something you want to do necessarily by yourself or without
Rob:the, um, Maybe the guidance of a physician because high dose niacin for
Rob:extended periods of time can Uh, actually cause issues like insulin resistance.
Rob:And there was a paper released just the other day that suggested that it can
Rob:actually damage, and I can't remember the name of them, so I'm not going to
Rob:try, uh, certain receptors in the heart for, with long term usage, which is
Rob:why it's now not being looked at as an effective way to boost your NAD levels,
Rob:as I'm sure you know, uh, vitamin B3, niacin is sort of the backbone, a lot of
Rob:these NAD precursors, NMN, NR, et cetera.
Rob:Uh, but whereas NR and NMN seem to have a slightly, well they do, they have a
Rob:safer safety profile with long term use.
Rob:Uh, it appears that niacin doesn't, that's not to say that obviously
Rob:you can't use it in the short term, um, especially at high doses, but
Rob:it's just something to be aware of.
Rob:And anyway, uh, the, the sauna detox protocol with niacin, I think it
Rob:was initially sort of put together by a gentleman called Ron Hubbard.
Rob:Uh, I think that's correct.
Rob:And yeah, the idea is that you take a large quantity of niacin prior to a sauna
Rob:session, and that helps to start, uh, liberating a lot of these toxins stored
Rob:in fat that you can then start getting out by, yeah, activating glutathione, uh,
Rob:synthesis, utilizing heat to directly, uh, push the toxins out through the
Rob:lymphatic system, out through the sweat.
Rob:Yeah, you can also utilize a number of other compounds along with niacin such
Rob:as caffeine, which is another great way to mobilize, to mobilize fatty acids.
Rob:Uh, you have Uh, compounds to increase circulation, such as citrulline
Rob:and other nitric oxide precursors.
Rob:Uh, and then there are a number of interesting products, such as Piperine,
Rob:uh, black pepper extract, which actually helped to increase the body's, uh,
Rob:thermal output of heat, uh, at a baseline.
Rob:So, yeah, these products, when you sort of use them in combination,
Rob:are, help the body to really sort of mobilize a lot of these toxins.
Rob:Afterwards, what you normally want to do, uh, is utilize some sort of binder
Rob:so that you can then get the toxins ready to be excreted from the body.
Rob:And that is essentially in a nutshell, uh, how sauna allows you with or without other
Rob:supplementation to start excreting a lot of these unwanted chemicals from the body.
Rob:I think it's also important to say that these enviro toxins aren't just limited
Rob:to heavy metals, but, uh, to plastics.
Rob:Um, there was a study the other day that, uh, I think it was within the
Rob:last two weeks, I have to double check the date, uh, microplastics
Rob:and nanoplastics and ath, uh, atheroma and cardiovascular events.
Rob:Yeah, I don't know if you saw it, but essentially 304 patients were
Rob:enrolled in the study and of that 304, I believe it was 257 actually came
Rob:out with elevated amounts of these microplastics in their coronary arteries
Rob:that resulted in the buildup of these, of these atheromas which is basically,
Rob:uh, a fatty deposit that is a, uh, a precursor to atherosclerotic plaque.
Rob:Um, so it now looks like microplastics are actually contributing quite
Rob:drastically to, to heart disease.
Rob:So, wow.
Rob:Just another reason, uh, that you want to try and sort of a, sort of
Rob:steer clear, uh, from them as much as possible, and then also detox from them.
Rob:As often as possible.
Rob:It really is.
Rob:Uh, quite a serious situation.
Rob:And when, I mean, when you look at the fish supply, for example, in the
Rob:sea, I mean, I'm sure you've seen those statistics it's, uh, yeah, you
Rob:can, you can, yeah, you can barely eat fish anymore without being
Rob:contaminated by either sort of mercurial or these microplastics as well.
Rob:So.
Rob:Yeah.
Rob:Yeah, no, it's, it's definitely just another reason to, to utilize Sauna.
Rob:I
Johannes:couldn't have said it better, Rob.
Johannes:I think that was very spot on.
Johannes:Um, maybe two, you know, two other benefits that I think are really important
Johannes:are, you know, the inflammation reduction.
Johannes:You know, I think we're an anti inflammatory property, so to speak,
Johannes:you know, I think inflammation, you know, tends to happen, I think, through
Johannes:lifestyle, you know, at least if it's unwanted inflammation, um, and I think,
Johannes:you know, infrared light, and that's what has actually been shown to reduce
Johannes:some of that oxidative stress or those free radicals, essentially, in our body.
Johannes:That's another one.
Johannes:And I think pain management, you know, I think we had a chat yesterday as well.
Johannes:And we, we sort of talked a lot about the fact that if someone is sick, like proper
Johannes:sick and, you know, maybe it's actually chronic joint pain and, you know, due
Johannes:to arthritis or, you know, other chronic inflammation in the body, you know,
Johannes:mobility or movement is super important.
Johannes:Um, however, you know, they literally can't get to that stage
Johannes:because they're not fit enough or because they're in pain too much.
Johannes:And I think.
Johannes:It's really when an infrared sauna or a sauna in general can actually
Johannes:provide a great starting point.
Johannes:Um, for some people it's sort of really regaining the health, you know, because
Johannes:obviously you're getting that detox and you're getting that cardiovascular workout
Johannes:and it helps you reducing inflammations, you know, and I think that itself
Johannes:makes a sauna a very, very interesting cocktail, you know, altogether.
Johannes:If you are really suffering from, from some serious pain or
Johannes:some serious different issues, you know, that's something we
Johannes:also hear on a day to day basis.
Johannes:And the last one is, uh, probably a mild form of hyperthermia you know,
Johannes:for those that do know infrared therapy itself is perceived as
Johannes:an alternative cancer treatment.
Johannes:Um, you know, it really raises core temperatures up to 39, 40, 40.
Johannes:1, five degrees Celsius.
Johannes:So that's nothing we can recommend here.
Johannes:And then also that Clearlight Saunas are designed for, however, if you use
Johannes:a sauna for 45 to 50 minutes, you'll actually get a soft hyperthermia we
Johannes:spoke about that earlier that your body really gets that artificial fever.
Johannes:It helps really upregulate the immune system.
Johannes:I mean, you know, you find calories as a consequence of that as well.
Johannes:Um, but I think the bottom line is that you just give your cardiovascular
Johannes:system and your immune system a really good spin, um, to make sure that,
Johannes:you know, it, it, yeah, it's just getting, it's stronger than before.
Johannes:And I really find that promising if someone is in chronic pain and they
Johannes:know exercise is the way to go, um, you know, but they literally can't
Johannes:because they're so much in pain.
Rob:Yeah, and we definitely touched on that yesterday as well, but, um, the
Rob:cardiovascular benefits just in terms of sauna being able to increase heart rate
Rob:is definitely nothing to be understated as well, I mean you sit in a, in a infrared
Rob:sauna and your, your heart rate steadily sort of climbs to 100, 110, 120 beats
Rob:a minute without too much effort and that's, um, And that's basically what
Rob:Peter Attia sort of points to as being this sort of zone two cardio zone, which
Rob:is great for, uh, mitochondrial biogenesis and lifespan expansion in general.
Rob:Um, when you sort of put the body into that stress state, it has to
Rob:sort of build more mitochondria through, uh, a number of pathways.
Rob:One of them being, uh, through a pathway called, uh, PGC1 alpha, which
Rob:is, uh, mediated by sirtuin enzymes, which is what a lot in the longevity
Rob:space are taking supplements, uh, like resveratrol and pterostilbene for.
Rob:Uh, so again, sauna is a natural memetic of a lot of these supplements
Rob:and is able to create a lot of the same, yeah, uh, outcome benefits.
Rob:Uh, in that respect, uh, I think a lot of the, the pain relief comes down to,
Rob:again, sauna being able to mediate a lot of these, uh, inflammatory cytokines, uh,
Rob:which are signaling molecules that control inflammation, as well as what are called
Rob:transcription factors, so, uh, I think they're, they're pretty big buzzwords,
Rob:but things like, uh, TNF alpha and nucleofactor kappa beta, As well as your
Rob:various interleukins, um, these are all molecules that help to, at one level or
Rob:another, mediate and control inflammation.
Rob:And, uh, ironically, you can shut down a lot of those pathways, uh, with
Rob:the, uh, with the inclusion of heat.
Rob:So, yeah.
Rob:Pain is an essentially a, uh, a nerve response to, to inflammation signals.
Rob:So if you can dampen down these signals, you can really lower, lower pain.
Rob:And I think there's also a lot to be said about building pain resilience in
Rob:something like a sauna in the same way that there is a cold shower, uh, or
Rob:cold, cold thermogenesis in general.
Rob:Um, when you put yourself into a state where you are acutely stressed, uh, you,
Rob:well, this is more of a, I suppose, a thought than anything else, but you are
Rob:able to just build more mental resilience.
Rob:You're doing a hard thing, aren't you?
Rob:And it sort of just creates that contrast between being in that acute
Rob:situation and then everyday life.
Rob:So.
Rob:There's probably a psychological component in that sense to it as well.
Johannes:100 percent and I think that is being picked up in studies as we speak.
Johannes:I know that in 2021, there was a sort of soft hypothermia study in the US from Dr.
Johannes:Ashley Mason.
Johannes:I think she actually has worked with from North Africa before and
Johannes:actually used the, you know, portable Clearlight to conduct that study.
Johannes:You can see it in the, I think, two hour interview that they conducted together.
Johannes:And she tried to measure the effects of, uh, hyperthermia or heat stress
Johannes:on mental well being, I think, specifically for people, uh, that
Johannes:were suffering from depression.
Johannes:And I think there was a significant number that actually witnessed an improvement
Johannes:in how they would describe their well being, um, you know, given the fact
Johannes:that they are, depressed at times.
Johannes:So I think there's a lot of prominent stuff happening.
Johannes:That's also why I believe this, as you said, like heat and cold exposure
Johannes:is really gaining a lot of momentum.
Johannes:Sure.
Johannes:It's good for your health, but it also really gives you that mental
Johannes:clarity at the mental resilience, which I believe we all need on a
Johannes:day to day basis at the moment.
Rob:Yeah, no, I just looked it up and the mechanism behind that appears
Rob:to be an increase in brave derived neurotrophic factor levels, uh, BDNF.
Rob:So the same, same molecule that lion's mane mushroom increases in
Rob:the body and that's Yeah, generally then linked to increased learning
Rob:but also mood and memory retention.
Rob:So that's It appears on the surface to be the main mechanism there.
Rob:Yeah, I think that sort of generally wraps it up, uh, for the most part,
Rob:uh, at least for an initial sort of foray sauna for people who are new
Rob:to an especially infrared sauna.
Rob:Um, is there anything else that you, uh, would like to touch on or do you think
Rob:we've covered most things at this point?
Johannes:I think we've covered a lot of things, I guess.
Johannes:You know, I just really want to say for someone that is new to this topic,
Johannes:I hope this wasn't too confusing, you know, I mean, I absolutely loved your
Johannes:biochemistry with, uh, Rob, I think you, you're a genius in that level.
Johannes:But what I specifically mean is those people that are looking at buying an
Johannes:infrared sauna, it can be very confusing.
Johannes:There's a lot of contradictory information when it comes to
Johannes:the different manufacturers.
Johannes:It's not regulated.
Johannes:So, you know, we've seen companies really promote that they saw enough
Johannes:help with vitamin D production, which is, you know, it couldn't
Johannes:be further away from the truth.
Johannes:So, I think it's just really important to sit down and sort of digest what we talked
Johannes:about in terms of good heat exposure, EMF and ELF being very important and then sort
Johannes:of really asking yourself the question of, you know, how can I really maximize
Johannes:this device on a day to day basis?
Johannes:You know, I love traditional saunas, but for me, they're absolutely
Johannes:impractical on a day to day basis.
Johannes:You know, it takes.
Johannes:You know, an hour to an hour and a half to preheat and then I,
Johannes:you know, another hour to use it.
Johannes:So, you know, 2 to 3 hours, um, is what it would take.
Johannes:And if you have the time, great.
Johannes:Um, but I think a lot of the times in infrared sauna really provides more
Johannes:value on a day to day basis, just because you're in and out and under an hour.
Johannes:And the electricity costs are probably 20 percent compared to the traditional sauna.
Johannes:So I think that's just something I really wanted to highlight because it's, you
Johannes:know, with some of these things, it's really important that you not just buy
Johannes:the device, but you actually use it.
Johannes:And I feel like with saunas, that is even more true because it is a great
Johannes:tool, but if you have one at home that you're not using, you know, it
Johannes:doesn't really give you the benefits.
Johannes:So I think that's true for a lot of things, but specifically with
Johannes:saunas, I believe like, you know, you really have to find something that
Johannes:works for you on a day to day basis.
Rob:Definitely.
Rob:Where can people find more about Clearlight, more about you?
Rob:I believe you've got a podcast as well of your own.
Johannes:Yeah.
Johannes:Yeah.
Johannes:We just launched, uh, we, we launched actually, it was called
Johannes:the sauna show on YouTube.
Johannes:Now it's called the HELSI show H E L S I.
Johannes:Um, you can find us in the UK on infraredsauna.
Johannes:co.
Johannes:uk or you just type in Clearlight saunas.
Johannes:Um, and if people want to find me for, Um, you know, for questions or ideas
Johannes:or podcasts, um, you can find me on LinkedIn on Johannes Kettelhodt which
Johannes:I'm sure Rob will link down below.
Johannes:Um, but yeah, I look forward to hearing from you
Rob:guys.
Rob:Thank you so much for the time.
