How Modern Lighting Can Destroy Your Sleep, Your Eyes & Your Health (& What You Can Do About It).

https://bengreenfieldfitness.com/lighthealth

Light can have a significant impact on your sleep and your health. In today's podcast, you're going to discover the hidden dangers of light-emitting diode (LED) lighting that most people are completely unaware of, including the risk of cataracts, blindness, age-related macular degeneration, mitochondrial dysfunction, metabolic disorders, disrupted circadian biology and sleep, cancer and more. LED light is currently used in applications as diverse as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, camera flashes, and lighted wallpaper. Large-area LED displays are used as stadium displays, dynamic decorative displays, and dynamic message signs on freeways. Thin, lightweight message displays are used at airports and railway stations, and as destination displays for trains, buses, trams, and ferries. LED's are also used in traffic lights and signals, exit signs, emergency vehicle lighting, ships' navigation lights, aircraft cockpits, brake lights, submarine and ship bridges, astronomy observatories, night vision, glowsticks and more. My guest is Dr. Alexander Wunsch, who is a physician, researcher and lecturer in light medicine and photobiology with particular interest in light effects and beneficial or adverse health impacts of solar radiation and artificial light sources on endocrine and cellular levels in humans. He conducts studies on photobiological effects of optical (UV, VIS and IR) radiation. In his private medical practice in Heidelberg, he uses therapeutic light spectra in combination with other biophysically based treatments and develops light equipment for medical and cosmetic purposes. He is associate lecturer at the Wismar University of Applied Sciences and mentors students in their master theses in light and health-associated topics. Alexander Wunsch presents at international conferences and operates as a consultant for federal authorities, media and industry.

During our discussion, you'll discover:

-Why LED light is so much different than other forms of light, especially with regards to how it affects your biology...[7:10]

Addendum

I have received multiple questions about the "Joovv" light that I use daily for testosterone enhancement (read more here or watch this video) - specifically whether the LED lights in the Joovv are harmful. Here is my take on that: The guy who makes the Joovv (Scott Nelson) is a friend of mine. Before starting Joovv, he spent close to 15 years in the medical device industry (with companies like Medtronic, Covidien, Boston Scientific, etc) and worked closely with world-renowned physicians, primarily the "who's who" in the fields of interventional cardiology, interventional radiology, and cardiovascular surgery. I do know he's studied the field of photomedicine quite a bit and have learned the following in conversations with him: -There are hundreds of published studies that point to the benefits of LLLT at specific wavelengths (both red and IR). There is a robust amount of clinical evidence that supports both red light (in the mid 600nm range) as well as IR. That's why Joovv offers the ability to add red, IR, or a combination of red/IR to their devices. So I don't *think* it's just "simple red light". -I asked them why LED's are used in Joovv, and they replied that you get 10x the efficiency without the heat loss, and included a graph that compares the WARP 10 device (LED-based red light) to a 250-watt heat lamp. (although way over-priced, the WARP 10 device was developed based on initial funding from NASA.) -With that said, you can benefit from incadescent heat lamps. The first Joovv prototype utilized eight 250 watt incandescent infrared heat lamps (that tripped breakers constantly). Countless studies show that 4-5 Joules of energy is required to get noticeable benefits from red light therapy; many show treatments at more than 100 Joules. You would trip breakers and die of heat exhaustion (LOL) trying to get this from incandescent heat lamps. Their tests using irradiance meters mirror the photon flux and literally, an inch away, you are getting less than 5 mW/cm2 from these lamps because over 90% of the energy is wasted as heat. Alternatively, their Joovv devices deliver over 50mW/cm2 at 6" way. And well over 100 mw/cm2 at an inch away. The efficiency of heat lamps is low in comparison to LEDs. So it would take 100 of these incandescent heat lamps bulbs (and more electricity than a 200 amp residential service can provide) to equal the output from their devices - not to mention the over-heating issue. -The key with any light therapy device is consistency. And the major problem with most light therapy devices (heat lamps included) is twofold: small treatment area combined with subpar output. That's why most of these devices recommend treatment times of 20+ minutes. They designed their devices to optimize for these two gaps in the market - treatment area and power output. The "net net" is that you don't have to use teir devices very long while still receiving benefits over a large surface area. Compliance is king when it comes to light therapy - and they feel their Joovv devices help with this issue. - Their devices emit negligible EMFs. Well below the 2 milligauss threshold. - Regarding red light and its ability to energize mitochondrial cytochrome C oxidase - see this seminal piece: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2790317/ - If you're comparing apples to apples, the Joovv devices are under-priced. Look at other players in the space - LightStim, Baby Quasar, etc. - when you consider the treatment size and power output, their devices are priced pretty fair. I mean, the LightStim LED bed is selling for $60k (not joking). The comparable Joovv Light Max starts out at $2395. And then there is this, from one of the lead Joovv engineers:

-Regarding the effect of LED lights on circadian rhythms, there have been many studies on the effect that different wavelengths have on the human body and how the time of day is also an important consideration (and I know you've covered this before on your podcast and blog). I think Mercola has an article that has some interesting information surrounding the wholesale replacement of incandescent bulbs with LED lights (as our everyday light source) that probably merits further study. -LED lights are not necessarily problematic sources of EMF. From the testing that I have done in multiple homes with EMF meters, the typical light switch and outlet generate more EMF than a high-quality LED transformer. Additionally, the majority of studies that review negative effects of LEDs specify that the source of the issue is the heavy dosage of blue and green wavelengths at night that can disrupt sleep cycles. This is consistent with what would be expected as the natural light we receive from the sun has a higher concentration of blue wavelengths in the morning and midday and then much of this is filtered out at dusk and we see a predominantly orange and red light distribution as our body prepares to rest. Here is a great meta-analysis that helps explain these concepts - http://photobiology.info/Roberts-CR.html. I have also seen several studies that demonstrate that red light helps with sleep quality (my teenage sons actually do their Joovv Light treatments right before bed). Here is an example of a study showing benefits of LED-based red light for sleep quality: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3499892/. -Finally, I think it's important to clarify that the human body receives light, from whatever source, as a distribution of light photons at a given intensity. Essentially, our cells don't care if the photons were created by the sun, LEDs, lasers, or incandescent bulbs; they simply respond to the wavelength and intensity of the light. As previously stated, there is an overwhelming amount of clinical research that shows significant health benefits from red light wavelengths as well as other wavelengths. Joovv constantly get reports from customers, some of which are MDs, that were initially skeptical but now have witnessed the healing effects of red light therapy. But to play devil's advocate...a physician I highly respect had this to say: "There is no question that LEDs are far more energy efficient, that is why the government banned the incandescent. They are energy efficient on steroids no question about that. But you are making the same mistake as the government saying that there is all this wasted energy. It is only wasted from the perspective of being able to provide visible light that can help you see. BUT that “wasted” energy is primarily FULL SPECTRUM near infrared with a touch of mid infrared in the example of heat lamps as you can see by the graph I sent on the last email. This “wasted” energy has very powerful biological effects, especially on the mitochondria." Anyways, just threw in these last bits for you true geeks out there.

Click here to order with your discount code. ThermoFactor is a synergistic formula that successfully addresses major issues associated with weight gain. The ingredients provide powerful thermogenic support and help control the appetite and blood sugar balance: Citrus aurantium Extract (Advantra Z) Advantra Z is extracted from the dried immature fruit of the bitter orange. More effective than ephedrine upon thermogenesis, it increases metabolic rate without the side effects. It helps suppress appetite and increase the release of fatty acids from storage. Athletes benefit from the ability to exercise longer without exhaustion or lean tissue loss. Green Tea Extract (Camellia sinensis): Green tea works synergistically with Advantra Z to increase thermogenesis. It is recognized as an overall health tonic containing powerful antioxidants. L-Tyrosine: The amino acid L-tyrosine increases the appetite suppressing abilities of Advantra Z. It is a precursor to a number of neurotransmitters and hormones. L-tyrosine is a minor stimulant for the release of growth hormone (GH) and thus important for metabolism (including thermogenesis). Chromium: Insulin plays a major role in fat storage. Chromium is a trace mineral that potentiates the effects of insulin, causing less insulin to be needed. Blood sugar levels are thus stabilized, and less fat is stored. Perhaps 90% of all Americans are deficient in chromium. It helps decrease LDL, cholesterol and triglycerides, while raising the levels of desirable HDL. Vanadyl Sulfate: Vanadyl sulfate mimics many of the activities of insulin. It is biologically active even in the absence of insulin. It possesses anti-catabolic properties: reducing the breakdown of muscle protein for energy. It also prevents the storage of excess carbohydrates as fat. Manganese: Manganese is another mineral that plays an important role in carbohydrate metabolism. It is a cofactor with many of the enzymes that affect sugar metabolism.

Have you seen the news stories about fat in fast food and the obesity epidemic? Did you see Morgan Spurlock's movie "Super Size Me"? Then guess what ... You've been fed a load of bologna. In this interview, comedian, author and speaker  Tom Naughton replies to the Super Size Me crowd by talking about how he lost weight on a fat-laden fast-food diet that included double quarter-pounders and fried chicken. He points out that nearly everything we've been told about obesity and healthy eating is wrong, and why fat is good. Here's a link to Fat Head on Hulu - or you can buy the Fat Head DVD on Amazon. --------------------------------------------------------------- Listener Q&A: Prior to asking your question, PLEASE be considerate and do a search in upper right hand corner of this website for the keywords associated with your question. 90% of the questions we receive have already been asked and answered here at BenGreenfieldFitness.com! ====================================== [contact-form-7 id="6222" title="Ask Ben"]====================================== Jeff has a call-in question about how to exhale when swimming. A listener has a call-in question about cramping in highschool football players. In my response, I recommend listening to this episode about muscle cramping with David Warden from TriTalk. Marcy asks: I just started a boot camp class 3 days a week. It's very hard. I'm not sure I've ever sweat that much. It's showing me that I'm not in as good shape as I thought. But I'm hanging in there. Would you say that that is enough resistance training. There are days that I am quite sore. Or should I add some gym days in between. Lia Marley asks: What are your thoughts on taking the supplement, DMAE? What are the benefits? I've heard that it can help with soreness and stiffness after working out. Glenn asks: Ben, i am training for my first marathon in 3 weeks. I understand some thing about the taper period, but i think i have heard you talk about the loss in fitness level during the taper. What really is going on physiologically during a proper taper? Surely it is more than "rest"? and, more importantly, what kind of GAINS are still available (strength, time to exhaustion, fat burning efficiency, etc.) to me in the next 2 weeks? Alex asks: Hi Ben. I heard you mention pro-biotics a few times but there's this supplement I was planing on buying that contains pre-biotics and they expressly mention it's not pro-biotics. What is the difference and which one is the preferred one? In my response to Alex, I mention Enerprime and Caprobiotics. Paul asks: I'm 5-foot-6 and weight about 150 pounds and I'd like to drop about five pounds by the time the next tri season rolls around. I've found it difficult to drop weight during the tri season, mostly because I don't want to short-change my nutrition while training hard. Now that the tri season is over, do you think it's a better idea to give my body a break and let it naturally pack on a couple of extra pounds over the winter (as it generally would) and then slim down to my new race weight as the next tri season approaches? Or would it be more effective to start slimming down now when I don't have the same nutritional needs as when I'm gearing up for a new season (or in the middle of the season)? Dave asks: I have been using the Restwise software that you discussed. My PO2 is usually in the 94-95% range. Recently had an unplanned ambulance ride and they measured PO2 @ 93. They were very surprised that it was that low. What do the numbers mean and is there an effective way to increase them. The EMT, knowing that I am a competitive athlete, thought it should be around 98%. In my response to Dave, I mention "Floradix" and also this episode with Restwise. -------------------------------------------- Remember, if you have any trouble listening, downloading, or transferring to your mp3 player just e-mail ben@bengreenfieldfitness.com And don't forget to leave the podcast a ranking in iTunes - it only takes 2 minutes of your time and helps grow our healthy community!
