Speaker:Welcome to the Biohacker's Podcast. My name is Teemu Arina and today I am talking
Speaker:to Sarah Turner about photobiomodulation, red light,
Speaker:all the different health being performance benefits that come from using red
Speaker:light, or near-infrared light.
Speaker:I got to know Sarah already I would say almost a decade ago and she's been always
Speaker:into light and frequency and for the last years a few few different companies.
Speaker:She's been working on photobiomodulation.
Speaker:So she's definitely a super enthusiastic top expert on this topic.
Speaker:So I'm very glad I had the opportunity to catch up with you on this topic.
Speaker:Welcome to the show. Thank you, Teemu. It's great to be on. And yeah,
Speaker:it's been a while. So looking forward to this chat.
Speaker:Great. So give us a little bit of a background on yourself so our listeners
Speaker:can navigate where you come from. Sure.
Speaker:So I have been in this kind kind of biohacking world for a while,
Speaker:but I started out actually as a pharmaceutical chemist.
Speaker:And I spent the first part of my career actually working for GlaxoSmithKline
Speaker:in their inhaled products, looking mainly at things like drug deposition in
Speaker:the lungs and what may affect that kind of deposition and to work out ways to improve drug delivery.
Speaker:So actually that was my start into thinking more holistically about the body
Speaker:because one of the main things that changes Dangerous deposition in the lungs
Speaker:actually is static charge.
Speaker:And that was something that I was investigating from the point of view of drug
Speaker:delivery through devices.
Speaker:But it quickly got me thinking about how you could more effectively change what's
Speaker:going on in the body and then need less of the drug or potentially not need the drug at all.
Speaker:So that's really how I started to get involved in it. Then it was called alternative health.
Speaker:Now that's morphed into biohacking. But I moved to California actually and got
Speaker:involved in structured water science and all all of that whole thing.
Speaker:And I very quickly started to think about the brain because my qualifications
Speaker:actually are neuroscience.
Speaker:So although I was looking at how light structures water, I soon started to think
Speaker:about, okay, if it structures water, how does that affect the brain?
Speaker:And of course, there is a whole world of people who were already studying that.
Speaker:So that was my kind of into photobiomodulation specifically for a brain function.
Speaker:And when I trace back the whole history of biohacking, there's different trends
Speaker:that I would say a decade ago.
Speaker:Blood blocking was a big thing. But I wouldn't say red light was yet a huge
Speaker:thing, but it has definitely grown into one in the last few years.
Speaker:Is there any specific studies or outcomes that have contributed to the increased
Speaker:interest in photobiomodulation specifically?
Speaker:Yeah, you're right. I think it's exploding right now. And maybe it did start
Speaker:off by people looking more structured water, because that was something when
Speaker:Jerry Pollack came out with his book, that people started to take notice of.
Speaker:And specifically, that was how light is affecting biology.
Speaker:And I think from there, people have extrapolated to this kind of amazing world
Speaker:of photobiomodulation.
Speaker:But I think also on the brain side, there are a lot of studies that are now coming to light.
Speaker:There's some really interesting research that's being done in Australia looking at the microbiome.
Speaker:Of course, Hamblin put out a brilliant paper called Shining Light Onto the the head.
Speaker:And that stoked a lot of interest in brain photobiomodulation.
Speaker:But yeah, I think red light generally, just because it works.
Speaker:I think people have been using it for a number of years, and it's been a bit
Speaker:word of mouth, especially for things like pain, wound healing, joint issues.
Speaker:So I think that's really why red light is starting to become talked about a
Speaker:lot more now, mainly because it works and people are getting relief.
Speaker:Yeah, I remember this Finnish guy, His name is Vladimir Heiskanen.
Speaker:He's been tracking basically all the research that comes out in photobiomodulation for a decade.
Speaker:And last time I checked, he had four and a half thousand different references
Speaker:on his database or something like this.
Speaker:And he has actually published since several reviews also on photobiomodulation.
Speaker:But there is a spreadsheet somewhere online which has all these different targeted effects of...
Speaker:Red light and near infrared light. And clinically, it has been used definitely
Speaker:in the treatment of diabetic patients, for example, wounds that don't heal.
Speaker:So the wound healing effects have been known for quite some time.
Speaker:And there's some interesting systemic effects that seem to point to yet undiscovered
Speaker:or not fully understood mechanism how the systemic effect happens.
Speaker:So when you shine the light, let's say, in the artery, which might heal faster
Speaker:on the other side of the body.
Speaker:And what is interesting is that although the mechanism of red light and near-infrared
Speaker:light has been defined as activation
Speaker:of cytochrome C oxidase in the mitochondria and production of ATP.
Speaker:Red blood cells don't have mitochondria, so it can't be attributed to this mechanism.
Speaker:So there's something else going on.
Speaker:So why don't you guide us into the basic mechanics or mechanisms of of red light
Speaker:therapy, and then we can maybe go into the different targeted uses in the body specifically.
Speaker:Yes. Yeah, you're right. I think there are probably multiple mechanisms that are at work.
Speaker:And we are mammals that are designed to be outside in the light.
Speaker:So it's probably no surprise that we're covered in all different kinds of light receptors.
Speaker:The most studied, I would say, of all of those is the cytochrome C oxidase,
Speaker:like you mentioned, which is within the membrane of the mitochondria.
Speaker:And that's one of the enzymes in the respiratory chain where we know that actually
Speaker:absorbs red light and in doing so sets off a cascade of reactions that leads
Speaker:to dissociation of nitric gas in favor of oxygen and a whole downstream effects
Speaker:such as production of ATP.
Speaker:Signaling molecules in reactive oxygen species and that transient release of
Speaker:nitric oxide gas, which leads to increased blood flow.
Speaker:So that's probably the mechanism that's most quoted but you're right,
Speaker:there probably are a lot of other very interesting mechanisms.
Speaker:I mentioned before that I was interested in structured water and I think
Speaker:As you get a longer wavelength of light, so light that's more in the near infrared
Speaker:than the red range above 900 nanometers, water becomes a main chromophore and
Speaker:main light absorber there.
Speaker:And then you could potentially be getting these effects of changing the structured
Speaker:water in the cell, changing protein folding, changing how proteins behave that
Speaker:are surrounded by water molecules.
Speaker:So that potentially is another mechanism.
Speaker:And yeah, you mentioned blood. Yeah, blood doesn't have the mitochondria, but it does have heme.
Speaker:Anything that has this aromatic kind of structure also potentially will resonate
Speaker:with certain light frequencies.
Speaker:So I think you're right. There is a whole plethora of mechanisms that we're
Speaker:only just starting to understand,
Speaker:but probably the most recognized and the most widely reported is this cytochrome
Speaker:C oxidase, where you're getting this production of ATP, which is energy for the body.
Speaker:And of course, the body functions a lot better when we have more energy.
Speaker:So that's probably one of the main ways that red light is having this therapeutic effect. Right.
Speaker:Photobiomodulation is also formerly known as low-level laser therapy.
Speaker:So why is that? Why LLLT and PPM?
Speaker:Yeah, it's a bit of a mouthful. I think just historically, it was difficult.
Speaker:The main light source that was used was laser. When they first discovered this,
Speaker:a guy called Mester discovered it with looking at rodents and wound healing, actually.
Speaker:Back then, laser was what you could could get hold of.
Speaker:It's only recently that we've had affordable and efficient light sources,
Speaker:which is a light emitting diode.
Speaker:So I think initially it was called low level laser therapy or cold laser therapy,
Speaker:just to reflect that was the delivery system that we were using to deliver this therapeutic light.
Speaker:But since the invention of these double-stacker LEDs and highly efficient light
Speaker:sources, they've now changed the name to reflect that.
Speaker:A group has got together and decided on photobiomodulation as the umbrella term,
Speaker:as it's more descriptive, photo as in light, bio as in biology,
Speaker:and to modulate or change something.
Speaker:So now that encompasses LED or LED therapy and the laser therapy.
Speaker:So really, it's just a word to bring things up to date and
Speaker:bring into the fold new ways of delivering the
Speaker:light new delivery systems right yeah
Speaker:another interesting thing to mention about that
Speaker:you mentioned on the effects so one
Speaker:of them is the activation of cytochrome c oxidase
Speaker:that is basically those chromophores that
Speaker:absorb this specific wavelength of light and
Speaker:this longer wavelength of light that dominates when the sun goes down
Speaker:so when you look at the typical panel it usually has
Speaker:something like 560 nanometers which is
Speaker:red light and then going above 800 nanometers which is infrared light near infrared
Speaker:light and if someone is like thinking about the infrared sauna here far infrared
Speaker:is in the thousands of nanometers so all those wavelengths have like slightly
Speaker:different effects and it has been argued or argumented that.
Speaker:When the sun goes down, with this wavelength of light, it is sending a signal
Speaker:to biological organisms to start the processes of healing and recovery.
Speaker:And that's what we are abusing here when you use red light therapies to trigger
Speaker:the body's innate healing potential.
Speaker:Now, the nitric oxide thing is also interesting.
Speaker:Increased blood flow. So if you have, let's say, some injury in some area,
Speaker:you can increase blood flow in that specific area.
Speaker:In addition to triggering this production of cellular energy and proliferation
Speaker:of anti-inflammatory cytokines as well.
Speaker:So there's this anti-inflammatory and analgistic effect when using photobiomodulation.
Speaker:And there's also a lymphatic component to this as well.
Speaker:So there's enhancement of nutrient supply and oxygen delivery,
Speaker:and that facilitates the removal of waste products.
Speaker:So the stimulation of not just the cardiovascular system, but the lymphatic
Speaker:system, I think is very interesting for the biomodulation specifically.
Speaker:And the anti-inflammatory cytokines then point to effects on modulating the immune system as well.
Speaker:That might help in the management of autoimmune conditions where there might
Speaker:be elevated inflammatory cytokines in the body.
Speaker:And then there's the tissue repair functionality.
Speaker:It has been shown that photobiomodulation can increase collagen production.
Speaker:Personally, I noticed supplementing on collagen every morning and then doing.
Speaker:Photobiomodulation that I used to have some scar tissue from burns,
Speaker:and they just got a lot better over time by repeated daily exposure to photobiomodulation
Speaker:and simultaneous administration of collagen peptides.
Speaker:And yeah, so that's an interesting thing. And then there's the neurological
Speaker:aspects, the effects on nerve cells, the support of nerve regeneration.
Speaker:And also, I would say with red light, the effects on reducing neuropathic pain.
Speaker:Basically, if I have back pain or any kind of joint pain or anything,
Speaker:it just goes away after 20-30 minutes of administration with photobiometrialization.
Speaker:It's the same for headaches.
Speaker:I've noticed if I have a headache, it might be blood flow, so a constricted
Speaker:blood flow that you can help.
Speaker:But I just feel feel neurologically like less brain
Speaker:fog so can you like based on what i just described talk a
Speaker:little bit about them functional effects on the body
Speaker:i would say on these wavelengths of light and happening there
Speaker:yeah and it's interesting you mentioned all those different systems in
Speaker:the body because you're right there is this kind of systemic effect
Speaker:or very holistic effect where of course all the systems are influencing all
Speaker:the other systems and when you're talking about the lymph system also with regards
Speaker:to the brain there's the glymphatic system and that's something think where
Speaker:there's some interesting research coming out specifically for sleep and brain function.
Speaker:That when you're using these red light, it stimulates that glymphatic drainage,
Speaker:which is actually the fluid that's going into the brain.
Speaker:And it seems to be something that where you have these kind of waves or pulsing
Speaker:of the glymphatic system,
Speaker:which flushes over the brain a few times during the night, and potentially that's
Speaker:what's washing away any misfolded proteins or any toxins that have accumulated.
Speaker:So again, it's very interesting to see this interconnectedness of the body with
Speaker:all the different symptoms.
Speaker:The glymphatic drainage system, along with the lymph system,
Speaker:the kind of the gut nervous system, the enteric nervous system, and the nervous system.
Speaker:I think that's the most interesting thing about red light therapy is that it
Speaker:seems to work on a lot of systems at once.
Speaker:And of course, when you improve the functionality of one system,
Speaker:you improve the functionality of another system.
Speaker:Something that I've really started to get interested in the last year is the
Speaker:effect of of red light on the microbiome.
Speaker:And there's a whole new field of study coming out of that called photobiomics,
Speaker:where researchers are actually looking at if you shine light onto the abdomen,
Speaker:can you actually change the composition of the microbiome, which of course is
Speaker:a huge topic right now with regards to any kind of long-term illness that's
Speaker:been connected to some kind of microbiome dysbiosis.
Speaker:And I'm not actually sure in human subjects whether you're actually directly
Speaker:targeting the microbiome or you're just changing the integrity of the gut,
Speaker:blood flow or the rest of it so you're making a better environment.
Speaker:But certainly on animal studies, mouse models and rodent models,
Speaker:they've shown very conclusively that you can actually change the profile of
Speaker:a microbiome to a more harmonious microbiome or a more what would be seen as
Speaker:a healthy gut profile just by using red light on this area.
Speaker:So to me, there's some really interesting research coming out now about different
Speaker:systems in the body and how you can target different systems to have a knock-on
Speaker:effect on other systems.
Speaker:So, for example, targeting the gut to treat the brain is a good one,
Speaker:or targeting the heart for the brain, or targeting the lungs for the gut.
Speaker:There's all of these different ways of thinking about the body where you're
Speaker:not just taking that more pharmaceutical approach of just having one treatment for one symptom.
Speaker:What you're doing is you're optimising all the systems in the body,
Speaker:hopefully, then you're bringing the general wellness up so that.
Speaker:The body can heal itself. So yeah, I think that is a hugely exciting thing about
Speaker:red light therapy, actually, the way that you can treat different systems and
Speaker:that in itself has this kind of holistic healing effect.
Speaker:Yeah. And talking about different organs, the thymus, for example,
Speaker:or the thyroid, those can be stimulated.
Speaker:So it's often described as stimulating a specific organ.
Speaker:But personally, I've noticed if I have any kind of traveler's diarrhea or any
Speaker:kind of gut issues, I ate something that was not good.
Speaker:I bounce back much more quickly by using red light therapy.
Speaker:It also helps with the pain modulation. So that goes away.
Speaker:So I guess it's somehow like helping the body to fight whatever it's going through
Speaker:in terms of inflammation and recovery.
Speaker:It just speeds it up. So if you think of wound healing, it might speed up wound healing by 2x.
Speaker:So your wounds heal two times faster.
Speaker:So if you think of phlegm and gout tissues, it can also help get out of that vicious.
Speaker:Cycle in a sense and if you have any kind of like chronic
Speaker:autoimmune conditions or so on so i
Speaker:personally have noticed like with some more chronic issues you
Speaker:give your body the ability to get out of that loop where
Speaker:it's not able to restore normal function necessarily so it might be like just
Speaker:the right tool to tip it to the right direction so i've seen people with rheumatoid
Speaker:arthritis for example get a lot better with that where the body is normally
Speaker:like constantly fighting condition when you combine that with other modalities that would help,
Speaker:let's say, anti-inflammatory compounds.
Speaker:Anything from curcumin, EZM-9-5, for example.
Speaker:Of course, changing diet in such a way that you don't stimulate the oteymo condition
Speaker:through the gut too much and you help the gut to heal some of these symptoms.
Speaker:Even in addition to rheumatism, there might be skin rashes, psoriasis,
Speaker:like a lot of different conditions can improve.
Speaker:And there's definitely studies on this, but it's very interesting.
Speaker:Yeah. You want to talk a little bit about the different organs and all that?
Speaker:Sure. I think that the body is always trying to return to homeostasis, right? So the body is.
Speaker:That's where it wants to be. And that's what it's trying to do.
Speaker:Even when you're getting all of these weird symptoms in a way,
Speaker:it's just the body trying to compensate for something that's missing or trying
Speaker:to work around some toxin or some injury.
Speaker:So the body always wants to get to that homeostasis.
Speaker:And so when you're shining this light onto wherever your target is,
Speaker:you're just helping the body to get there.
Speaker:But for sure, I think there is a lot of studies. We
Speaker:mentioned that database earlier where there's thousands
Speaker:and thousands of study and you can look at anything that you
Speaker:want to look at bone or like you say heart tissue
Speaker:thymus whatever it is and there are a lot of studies that's done on that because
Speaker:really we're giving the body energy we're giving the body blood flow we're signaling
Speaker:to the cellular dna what's going on in the mitochondria so your body can make
Speaker:the adjustments so really wherever you're putting the light you're having this effect.
Speaker:Things like using long bones to stimulate stem cells or adipose tissue to stimulate stem cells.
Speaker:What you're doing, again, is just giving the body the tools that it needs for self-healing.
Speaker:So I've also seen people use the light for all kinds of different things.
Speaker:Personally, I think stomach issues respond the most rapidly and seem to get the most effect.
Speaker:And maybe that is because you have this kind of combined effect of
Speaker:increasing blood flow energy and reducing the inflammation and
Speaker:because the gut is an easy target because we're fairly transparent and near
Speaker:infrared light actually but it obviously depends on the delivery system how
Speaker:deep into the body the light can go if you're some of the deeper organs maybe
Speaker:you're getting more of an effect
Speaker:of improving the environment rather than actually stimulating the tissue.
Speaker:But those things that are nearer to the surface, the gut, like you mentioned,
Speaker:the thymus, those places you can maybe stimulate more directly and potentially
Speaker:have a quicker effect there.
Speaker:So yeah, I think really whatever organ you're targeting, whether you're actually
Speaker:having a knock-on effect by making more blood flow, making more energy,
Speaker:or whether you're actually stimulating the organ, which again,
Speaker:extremely possible, that's what you're doing.
Speaker:You're letting the body get to its own homeostasis quicker than it would before.
Speaker:And of course, anything that you're doing to improve that grounding,
Speaker:eating good food, all the good biohacks, it's just preparing the body and giving
Speaker:yourself more chance to get there a lot quicker.
Speaker:And it's interesting, actually, with some of the compounds you mentioned,
Speaker:things like turmeric, things that are very brightly coloured are probably light activated too.
Speaker:Their structure is going to resonate with the light to some degree.
Speaker:And I think, again, this is probably research that's for the future.
Speaker:We haven't quite got there yet, but soon we'll work out how to activate certain
Speaker:supplements and compounds with certain wavelengths of light to increase the
Speaker:efficacy of those compounds.
Speaker:So, yeah, for sure. We're just giving the body the tools it needs to do its thing.
Speaker:And there's, of course, there's this dose response curve that like too little,
Speaker:there's not much effect and too much, there might be a reverse effect, a detrimental effect.
Speaker:So with photobiomodulation, it's all about the power of the LEDs,
Speaker:distance, and then the duration.
Speaker:Personally, how I use that, if I put it like right on the skin,
Speaker:going for a joint, for example, infrared light goes, near infrared goes deeper than red light alone.
Speaker:But so if you want to really target a joint, then I go close to the joint and
Speaker:then it might be just like five to 10 minutes, maybe 15 maximum is just a good dose.
Speaker:While if I'm lying down or under
Speaker:red light device for whole body treatment
Speaker:or upper chest or whatever back and
Speaker:the distance from the lamp is let's say 10-15 centimeters then I might stay
Speaker:there for half an hour and if I increase the distance from the body then it
Speaker:goes like 45 to hour even but one should always start with these just testing
Speaker:how their body and skin and everything everything reacts to.
Speaker:That's not like harmful.
Speaker:It's not going to tan you, which is funny, like some people who have bought
Speaker:a red light device, they claim they like saw a nice tan, but maybe it's more
Speaker:like a blood flow that they notice.
Speaker:But it's quite interesting, actually, when you look at these chromophores,
Speaker:so chromophores that absorb different wavelengths of light.
Speaker:So we mentioned cytochrome C oxidase, that is about 600 to 1000 nanometers where
Speaker:it peaks off the absorption of that wavelength of light. Now,
Speaker:if you look at something like hemoglobin.
Speaker:The oxygen-carrying thing in red blood cells, that is less than 600 nanometers, about 500 to 600.
Speaker:Then plants have chlorophyll, which is like one molecule difference from the
Speaker:chlorophyll that carries oxygen in plants, which is green, in humans is red.
Speaker:With hemoglobin, it's one molecule difference.
Speaker:And then when we go into melanin, which is in the skin, the pigment that it
Speaker:actually actually absorbs mainly UV light and blue light, and it really doesn't
Speaker:absorb this red or near infrared or whatever.
Speaker:The higher the frequency, the less melanin is absorbing it.
Speaker:Then you have in the eyes, you have the retinal cells, you have also carotenoids,
Speaker:these organic pigments that are also in plants, but which are really important for eyes.
Speaker:So carotenoids are about 400, 400-500 nanometers.
Speaker:Beta-carotene, for example, is about 450 nanometers.
Speaker:Interestingly, it's the same as bilirubin, which is the bile-producing compound.
Speaker:It's about 450 nanometers or so.
Speaker:And basically what blue light does, it helps to break down bilirubin,
Speaker:products that can be more easily eliminated by the body.
Speaker:So there's this whole day-night cycle, how our eyes, our bodies,
Speaker:blood, everything is like reacting to different frequencies of light.
Speaker:And it's fascinating that there is even these flavoproteins,
Speaker:flavins, those are actually, they also peak around 450 nanometers.
Speaker:So they are important cofactors in various redox reactions in the body.
Speaker:The whole recycling energy basically is connected to different wavelengths of light in the body.
Speaker:It's fascinating. I mean, if you shine a flashlight on your hand,
Speaker:a certain way when it's coming through, they see what light gets absorbed by the cells.
Speaker:And eventually, all of that has a biological effect, not just to regulate our
Speaker:circadian rhythms, which is another effect, of course, the intensity of different frequencies,
Speaker:day and night cycle, but it's also helping these cyclical processes in the body.
Speaker:So I find it very fascinating how it all functions.
Speaker:Probably light is being transferred into different forms of light.
Speaker:You can shine light onto the mitochondria, red and the infrared,
Speaker:and then the mitochondria is actually emitting its own light predominantly in the UV range.
Speaker:So you're transferring the wavelength of that light.
Speaker:So the body is doing all of this communication with light, with like you say,
Speaker:all the different light receivers depending on the structure and the resonance
Speaker:that's going on in the body.
Speaker:So potentially some of the effect of this light could be how we're stimulating
Speaker:further further biophotonic emission.
Speaker:It's especially interesting in the brain because that has implications for how
Speaker:our brains are actually functioning and how obviously a lot of our processes
Speaker:seem to be quicker than we would expect with the model of the body that we have at the moment.
Speaker:So this goes into that kind of quantum biology piece where we're looking at,
Speaker:okay, how are we transferring energy or how is the body actually signaling?
Speaker:Could part of that signaling actually be with light?
Speaker:So you're right, you have all these different molecules that are resonating
Speaker:at different frequencies and absorbing light, but they're also potentially putting
Speaker:out light of other frequencies.
Speaker:We are literally beings of light in that we're absorbing light and we're also
Speaker:emitting light and potentially our cells are communicating via that light.
Speaker:And certainly that's been seen in a lot of studies with bacteria.
Speaker:We know bacteria emit light and it seems like they do use that light as some form of communication.
Speaker:So I think from a point of view of looking at the quantum biology angle and
Speaker:looking at things like biophotonic emission, that again is something that's
Speaker:fairly in its infancy right now.
Speaker:Not a whole lot of funding to study things like that, but people are starting
Speaker:to get more of an idea of perhaps this is much more important than we previously thought.
Speaker:Indeed, yeah. We are definitely responding to our environment in so many different
Speaker:ways. We are biochemical.
Speaker:Bioelectrical maybe even like biophotonic entities
Speaker:and if you think about it photoreceptors just
Speaker:like cells primarily retinal cells
Speaker:have this capability of responding to light but
Speaker:there's also non-visual photoreceptors in
Speaker:the body melanopsin is a good example that photomigment that
Speaker:really is involved in the circadian rhythm and pupil
Speaker:responses and all of that and if you
Speaker:look at plants the bacteria you mentioned bacteria
Speaker:so they do have mechanisms to
Speaker:detect light and of course photosynthesis is
Speaker:an important process like thinking about our ancestors but also like signaling
Speaker:in a sense and there's probably nothing more beautiful than bioluminescence
Speaker:bioluminescent algae communicating with each other and making rituals yeah but
Speaker:let's talk talk about the practical details of photobiomodulation.
Speaker:So what are your favourite protocols or applications of photobiomodulation specifically?
Speaker:Where do you apply it and what kind of effects are you personally looking at?
Speaker:So I've been to this whole systemic thing and finding the best way to actually
Speaker:deliver light to the body to have an effect.
Speaker:So I've for the last five years really been solely focused on how to deliver
Speaker:light most effectively for brain optimisation.
Speaker:And it is actually quite difficult to get light onto the brain because although
Speaker:we are fairly transparent to near-infrared, we still have to get through bone
Speaker:and connective tissue and a lot of things to actually get to the surface of the brain.
Speaker:One of the ways is to use a longer wavelength of light for potentially a deeper penetration.
Speaker:I've been utilising not only the two main wavelengths, which is like the visible
Speaker:red and the 850 near-infrared, but also going up to 1070 nanometres. So that's interesting.
Speaker:And even then, the evidence shows that if you're you're shining light actually through the skull.
Speaker:Even if you've got quite a strong light right up against the head,
Speaker:you're still only getting between one and 3% of the photons actually getting
Speaker:to the surface of the brain.
Speaker:So I've really working on, okay, let's utilize this systemic effect a bit more
Speaker:and shine light somewhere where we know we can actually deliver a lot of photons.
Speaker:And so that's shining light onto the gut. And I think that's probably the best
Speaker:target for the brain because we don't call the gut the second brain, not for a reason.
Speaker:We We have a lot of, we have the vagus nerve there, we have stem cell production,
Speaker:we have neurotransmitters, we have the endocannabinoid system, and it's an easy window.
Speaker:You can easily expose a good proportion of the gut and you know that the light
Speaker:penetrating at least a couple of centimeters.
Speaker:So for me, that's what I've been really working on for the last five years is,
Speaker:okay, how can we develop some tech that we're targeting the brain,
Speaker:but we're not necessarily shining the light directly onto the brain solely.
Speaker:Maybe a dual device approach where you shine light onto the brain.
Speaker:And maybe modulate that with the pulse frequencies, which again is a whole other
Speaker:avenue, which is very interesting, more neuromodulation, but then actually using
Speaker:the gut as the main target for
Speaker:the brain to actually make sure you're delivering a good dose of light.
Speaker:Because all of that blood we know that's going to carry the light and we now
Speaker:know that mitochondria are free floating.
Speaker:That's a fairly recent finding that was only published in 2019,
Speaker:I believe, the fact that that we have mitochondria that can migrate around the body.
Speaker:So utilising the gut as the best target for a brain health effect.
Speaker:And so far, I've been looking at a lot of the research. I've got a few pilot studies going.
Speaker:I know Dr. Ann Lee, but in Australia, has got some really interesting data on
Speaker:Parkinson's disease using the gut as a target.
Speaker:There are some other researchers who are also looking at this,
Speaker:especially in the south of France.
Speaker:There's a group that are using a mass model of Alzheimer's and getting hugely
Speaker:increased effects when they target the gut and brain together.
Speaker:They've done studies on a mouse model where they target the brain,
Speaker:they get an effect, they target the gut, they get an effect.
Speaker:They do both together. You seem to get this much increased effect.
Speaker:There's a synergistic effect there.
Speaker:So that's really been my focus on, okay, perhaps the best way that we can deliver
Speaker:light to the brain is actually not by targeting the brain directly,
Speaker:but by targeting the gut and then maybe modulating brainwaves using pulsed light to the brain.
Speaker:So you're working with Seratribe and you have a device for doing all this.
Speaker:Can you describe how it works?
Speaker:So it's a fairly simple device where I just have a body panel.
Speaker:So the panel has the two wavelengths, the 630 and the 850, because we know there's
Speaker:not much barrier there at the gut.
Speaker:So you're getting a lot of light to the gut there.
Speaker:Delivering a fairly high dose, about 30 joules per centimetre squared,
Speaker:which is a good dose of light to the gut.
Speaker:But at the same time, a headband that has different pulsed frequencies,
Speaker:because that's an interesting thing that we know now that we can do with light,
Speaker:is we can modulate what's going on in the brain by pulsing the light,
Speaker:which really just means turning the light source off and on at a certain hertz
Speaker:rate or a certain times per second.
Speaker:And that seems to have really interesting effects, especially for some of the
Speaker:neurodegenerative conditions or for things like meditation and focus.
Speaker:So my band, it's got four different wavelengths in the headband.
Speaker:So as I said, it's got 630 and 850, but also those longer wavelengths, 940 and 1070.
Speaker:And then it has six different pulsing schedules ranging from 7.8,
Speaker:which is human resonance, right up to 100 hertz,
Speaker:which is perhaps not so perceptible to the brain in that you don't see a reflected
Speaker:change in brain but it does seem to increase altered states or meditative states.
Speaker:So that's the idea is to utilize the gut as the target using a body panel, the Sarah body panel.
Speaker:And then you target the brain with a headband that utilizes this pulsed frequency.
Speaker:And it does shine light. You are getting a little bit of light to the brain.
Speaker:And if what we were talking about before, you have these quantum effects,
Speaker:you have water effects, you have the brain producing bio photons,
Speaker:that small amount amount of photons delivered to the brain has been shown to
Speaker:have a hugely beneficial effect.
Speaker:I just want to maximize that effect by treating the gut at the same time.
Speaker:Of course, a lot of studies are done on degenerative diseases.
Speaker:That's where the holy grail, of course, is if this could help with Alzheimer's or dementia.
Speaker:So that's where a lot of studies are done. Now, it's very interesting because
Speaker:it does seem to stimulate stimulate brain-derived neurotrophic factors.
Speaker:So in neurological applications, EDNF is important because it stimulates and
Speaker:is involved in neurogenesis.
Speaker:So basically creating nerve tissue and also in neuroprotection,
Speaker:so like slowing down your degenerative diseases.
Speaker:And also in brain injury, that's one area that is also interesting is if you
Speaker:get a concussion, maybe this could help other protocols involved.
Speaker:Now, there is the glymphatic system. So the lymphatic system that extends to
Speaker:the brain is called the glymphatic system mediated through glial cells.
Speaker:So photobiomodulation does affect glial cells, just for example,
Speaker:astrocytes and microglia.
Speaker:And that might promote an anti-inflammatory response as well.
Speaker:So that kind of flushing out toxic byproducts is probably...
Speaker:Important for conducting this kind of environment where neuronal survival is objective.
Speaker:Then there is, you mentioned the pulsation.
Speaker:I remember ViaLite, for example, had, I think in Nature magazine, an article about this.
Speaker:They use like a intranasal delivery to the brain. And what happens there is
Speaker:synchronization of brainwaves.
Speaker:So just like with music, if people have heard heard about binaural beats,
Speaker:you can also use light for the brain waves to synchronize.
Speaker:So you can induce certain brainwave patterns that could be, let's say,
Speaker:related to a meditative state.
Speaker:But that might have implications also for certain brain-based conditions like
Speaker:anxiety or mental health issues or PTSD, where I believe there is a huge gut
Speaker:brain component usually involved.
Speaker:So often people who have anxiety, depression, there might be a gut component involved.
Speaker:So there has been observations on disturbance of the microbiome and gut lining
Speaker:and all of that. And when you fix that, it also helps the brain.
Speaker:I think there's a two-way communication that is key. You have to target both.
Speaker:And that's why you get this reduction of brain fog and maybe improved mood and
Speaker:all that by also fixing your gut simultaneously, not just focusing on the pain.
Speaker:So basically these symptoms related to depression and anxiety,
Speaker:there might be an inflammatory condition behind that.
Speaker:By the way, one thing that we didn't mention on the effects,
Speaker:we mentioned cytochrome C oxidase and mentioned nitric oxide,
Speaker:but we didn't talk about reactive oxygen species.
Speaker:Why reactive oxygen species are interesting is that when you have this pathway
Speaker:of reactive oxygen species activated, it also activates transcription factors like NFKB and AP1.
Speaker:And these regulate gene expression related to cell survival.
Speaker:Inflammation, and cell proliferation.
Speaker:Although it's related to oxidative damage, and then you have antioxidants that help fight that.
Speaker:But in the body, to speed up healing, you might want to actually stimulate cell
Speaker:renewal and recycling and not just inhibit that.
Speaker:There's a lot of interesting effects there.
Speaker:So if you have like a brain-derived vision, what you could potentially do.
Speaker:So basically, your favorite application is on the gut, but you also mentioned
Speaker:that on your device, you have four wavelengths.
Speaker:And basically, the red light, the shorter wavelengths that probably when applied
Speaker:on the skull is mainly on the tissue level, maybe on the skull level,
Speaker:like maybe blood flow there.
Speaker:Yeah, hair growth, like all of that is, of course, like another brain or head-related
Speaker:issue that that people want to work with.
Speaker:So that might also improve like air growth. Now that infrared light.
Speaker:Goes deeper, might reach the brain. But with this longer wavelength,
Speaker:like 1070, I would imagine it goes even deeper, so strong enough to penetrate the skull as well.
Speaker:I think even the 850 will penetrate the skull. We know that the 850 will get through.
Speaker:There have been a lot of studies on that. But I'm specifically thinking I want
Speaker:to target the water because water absorbs light when you go above 900 nanometers.
Speaker:So actually, it might be that those long waves like the 1070 doesn't actually
Speaker:penetrate a lot deeper because the water will absorb a lot before it really travels down far.
Speaker:So probably the 850, the 940 and the 1070, perhaps they penetrate to a similar
Speaker:depth considering that the longer wavelengths are going to be absorbed by the water.
Speaker:But I think from all the studies that have been done, they've only been done
Speaker:on mainly on 850 and people are seeing amazing results.
Speaker:So it's obvious that you really only need to get a small amount of photons just
Speaker:just to the surface of the brain to have an effect.
Speaker:And I think, again, that's something where more research is going to come in,
Speaker:perhaps because the brain has a lot of projections from deep in the brain to the surface.
Speaker:You're actually affecting the connectome or what's actually going on in the brain.
Speaker:Maybe even the neurons are acting as fiber optics, like wave guides for the
Speaker:light that's directing the light deeper down.
Speaker:We don't know actually right now why shining light just onto the surface of
Speaker:the brain has such profound effects for diseases like Parkinson's,
Speaker:which is due to the substantia nigra fairly deep in the brain.
Speaker:So I think just getting light onto the surface of the cortex is enough.
Speaker:We know that from studies. It's just interesting.
Speaker:We're going to find out soon enough how are we affecting deep structures.
Speaker:Is it more this systemic effect?
Speaker:Is it mitochondria? Is it the water? Is it some kind of quantum effect?
Speaker:And that's why I think this is such an exciting field to be in because there's so much left to learn.
Speaker:We really are at the early stages of the research.
Speaker:Yeah, I believe so. If we take something like optogenetics, where we might induce
Speaker:light-sensitive proteins to respond to light,
Speaker:I would imagine like with a therapy where you're putting something into the
Speaker:bloodstream that gets into the brain, across the blood-brain barrier,
Speaker:you can use then light to activate that.
Speaker:Personally, I'm using sometimes a dental device that reduces plague formation
Speaker:by targeting the bacteria specifically.
Speaker:So you have this specific compound that you gargle with and that makes only
Speaker:that specific type of autogenic bacteria light sensitive and then you use a
Speaker:device to activate basically destroy only that type of bacteria with light so
Speaker:I would imagine you could potentially treat some brain derived conditions.
Speaker:That's interesting Teemu, where do you shine the light?
Speaker:In the mouth, yeah. It's called Lumoral, this device specifically.
Speaker:It's some kind of seaweed extract that they use.
Speaker:I think it's basically like it attaches to the bacteria only,
Speaker:and then this light, which is more, I think it's more like UV.
Speaker:It looks like blue-violet-ish light, and that then destroys the bacteria.
Speaker:It's incredible what it does to plague. mouth.
Speaker:It's all gone after a treatment. And there's a lot of interesting studies behind
Speaker:that for treating gum disease and all kinds of stuff where it's very hard to
Speaker:get into the deep pockets where that bacteria is residing.
Speaker:You're able to use something like this. Yeah, it's a non-invasive methods,
Speaker:right? And they have actually, I remember reading a paper and a study published.
Speaker:It was in South America. I think it was in Brazil. They studied herpes and they
Speaker:figured out a similar way of marking that virus with light and making it photosensitive
Speaker:and then being able to destroy it.
Speaker:You can destroy the herpes virus anywhere. You don't even need to make it photosensitive.
Speaker:If you use UV light on the herpes virus, I know one of my scientific advisors,
Speaker:Professor Paul Chazot, was doing studies actually using UV light on- Yeah,
Speaker:specific way like on viruses.
Speaker:Yeah, yeah. You can just get little devices. If you've got a cold,
Speaker:because herpes, it's like Like the cold sore virus, you can actually just use
Speaker:a very pinpoint UV light.
Speaker:And things like acne, we already know things like acne, the bacteria that causes acne.
Speaker:You can use a blue light on that. You don't need to photosensitize it.
Speaker:It's just because of the way that the bacteria have different kind of cell membrane.
Speaker:You can destroy those with the blue and UV light without damaging the human
Speaker:cells. I think you can also do the same for photosensitization with certain
Speaker:types of cancer cells and a lot of things.
Speaker:So I believe there will be a lot of therapeutic agents that we will be developing
Speaker:in the next decade in a very targeted way without using a scalpel where we can
Speaker:get into the tissue and we can get rid of every single cell.
Speaker:Like if you think of something like warts, for example, which have high reoccurrence
Speaker:because you have to get every single cell out that has that virus.
Speaker:And if there's even a little bit left, it might renew itself.
Speaker:But if you can target every single cell with a targeted therapy,
Speaker:they're using lasers right now to cut this out or freeze them or whatever.
Speaker:But there might be a much more, I would say also less traumatic ways to treat things.
Speaker:Yeah, less traumatic on the body. you're being able to target.
Speaker:Certainly, I spoke to a doctor the other
Speaker:day who had developed a brilliant photosensitizer for looking at tumours.
Speaker:So you could deliver this photosensitizer and then you could wear a special
Speaker:pair of glasses so the surgeon could more comprehensively make sure that there
Speaker:was none of the tumour left in the body.
Speaker:And that's technology that he'd already developed that's out there already.
Speaker:He was a dentist who'd done a lot of stuff with, because a lot of this This
Speaker:stuff is in dentistry already, as you were mentioning.
Speaker:But if you can have different ways that help surgeons to be more effective in
Speaker:what they're doing, also, that's hugely effective.
Speaker:And there are tools that are out there now. But you're right.
Speaker:Anything that we can do to make things less invasive, less traumatic.
Speaker:More easy for people to do so they don't need to go into hospitals,
Speaker:can do things in clinics where potentially you're not going to get reinfected with something else.
Speaker:Yeah, I think that's definitely the future for a lot of these technologies.
Speaker:I remember a professor demonstrating an open heart surgery technique where they
Speaker:would create this kind of photosensitization of specific types of cells in the heart.
Speaker:And when you're like cutting in to an open heart that you're not avoiding like
Speaker:very key arteries, which is probably a good idea.
Speaker:And you're basically operating at like nanomicromillimeters or whatever.
Speaker:You might like make a huge mistake by just going a little bit off like it's
Speaker:actually good that you have something that where they can see better into the
Speaker:tissue just doesn't look all the same but they can distinguish between cells
Speaker:and in that way you can also then distinguish
Speaker:get some potential problematic things out. Now, let's go back to earth.
Speaker:On a regular person who is looking
Speaker:into these devices, there is a lot of different options on the market.
Speaker:You have spotlights, you have panels, you have bigger stacks of panels,
Speaker:you have portable ones, you have things that are designed to be applied mainly
Speaker:on the face for for beauty things.
Speaker:You have different LEDs ranging from anywhere between 600 and 1100 or 1170, whatever, nanometers.
Speaker:In this sea of opportunities for using photobiomodulation, what would be your recommendations?
Speaker:I can personally say that there's no single one-size-fits-all solution.
Speaker:So I have different devices for different situations.
Speaker:But what is your advice if someone is looking for a device like this?
Speaker:I think you need to be aware of your goal. What is it that you're trying to
Speaker:achieve with the red light device?
Speaker:Because there are all kinds of different form factors. And certainly if you're
Speaker:looking for general wellness and something that you can maybe incorporate into
Speaker:your morning meditation, then the panels are great.
Speaker:You can get a panel and you can sit in front of that and they're cool.
Speaker:I think if you're looking at a more kind of healing therapeutic function,
Speaker:you really need something that potentially contours to the body.
Speaker:Because Because don't forget, light will only go in a straight line.
Speaker:Light is not going to bend to you. It will bounce off you and all kinds of crazy things.
Speaker:So if you really want to deliver a good dose of light to the body,
Speaker:it's best to get something that...
Speaker:You can shape around the body, especially if you're trying to get to an injured joint or something.
Speaker:So I think for wellness, the panels, for joints, some kind of flexible device
Speaker:that you can strap around the body and you need to get it from someone where
Speaker:they have listed their specification because it does need to be a reasonable dose of light.
Speaker:We spoke a bit about this kind of Goldilocks effect of too little is not enough and too much is too much.
Speaker:I think it it is quite difficult to overdose with red light,
Speaker:but it is easy to not do it enough.
Speaker:So I think making sure you're getting something that's got a decent milliwatt output.
Speaker:And at the moment, there are no standards,
Speaker:unfortunately, because the form deliveries are just so different.
Speaker:But if you know that you're getting it from a good manufacturer where they've
Speaker:given you your specification and they have a rationale for their dose,
Speaker:then at least you're getting a good dose according to the manufacturer.
Speaker:And then again, something, my device is portable and easy.
Speaker:It's battery operated and shielded and Bluetooth protected and all of that.
Speaker:They may be things that are interesting for people who are looking for something
Speaker:that they use every day for concentration, for focus, for wellness.
Speaker:So I think they're the things you need to look at. What do you want to use it for?
Speaker:If you really want to get into joints and into difficult to to reach places,
Speaker:you do need something that contours around the body so that you get the full dose of light.
Speaker:And if you imagine light is coming at you like in arrows coming down,
Speaker:if you have something that's curved around a joint, you're getting the effect
Speaker:of all of those lights converging on a point, which is great.
Speaker:That's what you want for a joint.
Speaker:You're not going to get that so much with something that's flat.
Speaker:Precisely. So yeah, it depends what you're trying to do. Just get something
Speaker:for your individual need.
Speaker:But yeah, the more focused you need to be, the more you need a device that's
Speaker:been specifically designed for that function.
Speaker:Yeah. I personally, I use these bigger panels in the morning just to increase
Speaker:blood flow and get ready for the day.
Speaker:Like I use it sometimes as a pre-workout almost because of
Speaker:the nitric oxide effect like some bodybuilders use
Speaker:beetroot i use red light and i think it's red
Speaker:light is more effective than beetroot for that specific reason
Speaker:and then it's important of course to be aware of
Speaker:this kind of biphasic dose response also known
Speaker:as the arndt-schultz curve or hormesis effect where
Speaker:low doses of light stimulate so then
Speaker:physiological processes and higher dose will inhibit those
Speaker:responses so you have to understand like the optimal dose like
Speaker:not falling asleep under your panel but like knowing
Speaker:the right dose and then like this like a targeted use
Speaker:i personally like these battery operated ones like
Speaker:yours to be used when i travel and also when i'm let's say sitting at my computer
Speaker:and chair or something i apply it on a gut or like a joint or something like
Speaker:this while i'm doing something else while a big panel will just like blind you
Speaker:and it's not so comfortable I mean,
Speaker:there's people out there like Ben Greenfield who have all these images of them
Speaker:using big panels while they use computer.
Speaker:I have no idea how they can do that. But I'd rather use a targeted device.
Speaker:And I've noticed like on shoulder area, neck area might be good while working
Speaker:sometimes to alleviate some neck stiffness and pain.
Speaker:So there's a lot of different reasons why you would have a certain device, different situations.
Speaker:And I would definitely get one that has these different frequencies.
Speaker:Because can you explain in what situation you don't want to activate,
Speaker:let's say, near infrared light?
Speaker:And in what situation, the red light is not that necessary. So you want to switch
Speaker:between mirror infrared and red light.
Speaker:Does anything come to your mind, like in terms of application?
Speaker:It's mainly a case of penetration depth because the red light is surface level.
Speaker:If you're looking to do things like we spoke about collagen and fibrinogen and all of those things.
Speaker:So if you're looking at something where you're fairly surface level,
Speaker:you want to stimulate, like, for example, a cosmetic application,
Speaker:or if you just want to stimulate the blood, like you said, a scar application,
Speaker:then the red light is a good option.
Speaker:The near infrared light is going to go deeper and you need that for a joint, for an organ function.
Speaker:To be honest, I think if you're using both together, that's great because you're
Speaker:going to target the surface and deeper still.
Speaker:So I don't see much wrong with using them both together for almost all applications,
Speaker:even in a cosmetic application.
Speaker:But certainly red light on its own is fine for just surface level things.
Speaker:Yeah. I remember reading specifically about shining the light on testicles. Oh yeah.
Speaker:And of course, that's very interesting for men if you're looking into testosterone
Speaker:production, because there is a mechanism with photobiomodulation that stimulates
Speaker:the lytic cells in the testes, which is responsible for testosterone production.
Speaker:So the idea is that that with this light exposure, you could enhance the mitochondrial
Speaker:function of these cells and that might lead into the.
Speaker:Increased production of testosterone. But I think there is like a dose and safety
Speaker:curve because your testes are outside of your body for a reason.
Speaker:So I wouldn't heat them up like too much with near infrared light,
Speaker:for example. I might maybe use more red light for that.
Speaker:That's a good question, like what's the right amount?
Speaker:I was going to say most of these devices, if they're good, they shouldn't get
Speaker:too hot because although you're using near infrared, it's right down down there in the 850s.
Speaker:So the body, it's not so much the thermal energy you want to have.
Speaker:The light pads should get warm, but they shouldn't get hot.
Speaker:So if they're getting really hot, either something's gone wrong with the fan
Speaker:on them or the output is potentially too high.
Speaker:Because I think even when you're doing testes, you still want to penetrate a
Speaker:little bit deep because you do want to get into the tissue.
Speaker:So I think you could use near infrared, but you just have to use your kind of common sense.
Speaker:If it's uncomfortable, don't do it. And you need a lot less time because you
Speaker:can adjust the dose by either increasing the output or the time.
Speaker:Both of those things are going to have an effect.
Speaker:It's like making a cake. You can bake something for longer on a lower temperature or vice versa.
Speaker:So I think for sensitive areas, you can use a similar device,
Speaker:use the near infrared, but just use it for a lot less time.
Speaker:And I have to say, just to put in there, Taimou, it is also for women too.
Speaker:Women also want to boost their testosterone.
Speaker:It's a question I used to get asked a lot more and I'd forgotten about it because
Speaker:actually at the last few events, people haven't asked me so much,
Speaker:but it used to be one of the main questions.
Speaker:Maybe because Ben Greenfield, I think he did that article, didn't he?
Speaker:About where he shines the light.
Speaker:And that became a big topic of conversation for a while. But certainly I think
Speaker:you can use these longer wavelengths, which potentially will get warmer,
Speaker:but just use them for less time.
Speaker:Maybe use them for a minute and you do it a couple of times a day rather than
Speaker:doing it for an extended period.
Speaker:A lot of it does come down to people taking a bit of sovereignty and a bit of
Speaker:self-responsibility and using the light in a way where you're using your body as a measure.
Speaker:You can tell if something feels good. You can tell if something's too warm because
Speaker:we are all individual and it's not one size fits all.
Speaker:Even things like skin tone has an effect on how the light is going to penetrate.
Speaker:So it's very difficult to give certain specific protocols because of that.
Speaker:But a lot of these devices are very user-friendly.
Speaker:Once you start using light and you get used to it, you can tell in your own body what's going on.
Speaker:Yeah, I think near infrared, yeah, you can use it even on sensitive parts of your body.
Speaker:You just have to do your N equals one and work out what works for you.
Speaker:Yeah, what I'm thinking about in terms of females is also like reproductive health and ovary.
Speaker:There's not that much studies, but I would imagine red light photobiomodulation
Speaker:might have an effect on follicular development, ovulation, like certain fertility aspects.
Speaker:I mean, if you think about the cellular energy production, ATP.
Speaker:The ovaries are also central in production of hormones like estrogen and progesterone.
Speaker:So like there might be a potential hormonal balance related effect there.
Speaker:Usually when you have men studying these things, they're just like first thing
Speaker:they do is like shine a light on their testicles or something.
Speaker:But like this is some super interesting area for study for sure.
Speaker:It is. And I did a little bit of digging into this at one point.
Speaker:And we're kind of biohackers so we're focusing on
Speaker:performance but actually there's a lot of data in things
Speaker:like farming because they're way ahead because this is
Speaker:a lot of money there's big money in farming is like prized cattle and things
Speaker:so they're already using these kind of like therapies things like sperm production
Speaker:in bulls things like fertility in animals because it works and they're getting
Speaker:results i think there are plenty of examples where this is actually being being
Speaker:put into practice and having a result.
Speaker:After all, we are all mammals. We're functioning on the same system.
Speaker:If it's working in those kinds of environments, it's going to work in a human
Speaker:environment. We just need to get the data out there and the clinical trials need to go ahead.
Speaker:But for sure, there's already evidence that it is having a huge effect on all
Speaker:of those things you mentioned, fertility and reproductive health.
Speaker:My friend's cat always likes to hang out around the red light panel when it's on.
Speaker:I don't know if it's because it's the heat or they know better than we do.
Speaker:Oh yeah, animals are so clever. I have a friend who does red light therapy for racehorses.
Speaker:Again, people who want to get the edge and know what's up, they are using this
Speaker:technology because it works. These animals are worth millions of dollars or whatever.
Speaker:They wouldn't do something if it wasn't effective.
Speaker:So I think there are a lot of lessons to be learned from what's already going
Speaker:on out there, you know, outside of the human domain.
Speaker:Precisely. That's already done on the genetic side, even supplementation.
Speaker:A lot of that has been applied on racehorses.
Speaker:So it's very interesting how this will be combined and what we can learn from
Speaker:it. But if you've seen on the internet people tanning their balls or buttholes
Speaker:with sunshine, please don't do it. There is a safer method.
Speaker:It's using near-earth red light and red light. Then you don't have the UV and
Speaker:all of that stuff going on. That might be a smarter idea.
Speaker:People in the north, they use these wake-up lights, like these so-called seasonal
Speaker:depression lamps, which is blue light, short wavelength of light,
Speaker:which helps them to wake up.
Speaker:But for me, like the red light and near infrared, it works better in those darker months of the year.
Speaker:And the reason is that the strength of the light also matters for circadian rhythm.
Speaker:So the intensity of light seems to be also a fact.
Speaker:So you can actually get similar seasonal effects also from very strong red light.
Speaker:But also the fact that when you're meditating in front of one of these panels
Speaker:and you feel this, I can't describe it, but it feels almost like being on the beach in sunshine.
Speaker:It's just beautiful warmth and just this sense of well-being that comes from
Speaker:it that I just don't get eyes closed in front, seasonal warmth.
Speaker:Light therapy lamp. So I rather opt for a really good red light near infrared
Speaker:light device if I have a choice in winter months rather than using a daylight lamp.
Speaker:But definitely it's useful when you work at the computer or something to have
Speaker:a bright light close by, but I always have my red light also there if I need it.
Speaker:There's different mechanisms with light through the eyes and light through the body, but you're right.
Speaker:The body responds to sunlight and in turn red light by by creating natural opiates, in fact.
Speaker:Our bodies want us to enjoy being in this light because we're meant to be out in it.
Speaker:It's healing for us. It's good for us. So our body provides us with those happy

Speaker:device, where should they go?
Speaker:Yeah, so it's just CeraThrive, which is C-E-R-A, CeraThrive.

Speaker:So cerathrive.com. And then all my socials are the same, CeraThrive or Cera.
Speaker:That's wonderful. Your name justifies the whole product already.
Speaker:So it's not a coincidence. It's a really good device and appreciate talking to you.
