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]

-The biggest sources of LED in your personal environment...[16:22]

-Why monitor and light bulb flickering is such a serious issue when it comes to your health...[19:35]

-How LED's (especially when used after sunset) vastly reduces the regenerative and restoring capacities of your eyes...[23:35]

-Why near infrared, which is missing from LED light, is so important for you to be exposed to...[38:45]

-What the healthiest type of lighting is to use and what should you look for when choosing a light...[53:00]

-The two parameters you must look for in a light bulb, and what numbers those parameters should be at...[54:20 & 56:20]

-Top recommendations for computer screens that don't damage your eyes...[70:15]

-And much more!

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.

First Name Last Name Email Cell # (1+area code)     --------------------------------------------------------------- Listener Q&A: ====================================== [contact-form 3 "AskBen"] ====================================== Eric asks: Yesterday I completed my first 130 mile weekend with 80 of those moles on Sunday. I did the best I could regarding nutrition in the saddle but I'm still super hungry today. What would be your replenishment plan after an effort like that. Garmin said I burnt up around 4500 calories. I'm 174 6'1 & male if that helps at all. Emily asks: I am a runner, and I used to be a smoker. I recently quit, but I am wondering if there are any supplements or health tricks that might help my lungs heal faster and to keep me motivated from going back to the dreaded cigarettes? I have run a marathon while smoking, and I can't wait to run one smoke free! Melanie asks: Not to keep on the whole fasted morning exercise thing that you've talked about, but I'm wondering your opinion on a very small woman with no muscle to lose on what point should I actually be concerned of "eating" muscle. I'm 5'2 and 105 and approx. 17% body fat. I want to get to 13 - 14% body fat but don't need to lose much weight or any muscle. Should I even be doing fasted exercise? Is it okay to do fasted 45 minute strength training? Susan asks: Please Help! How can I tell if I'm truly in menopause or experiencing exercise induce amenorrhea. I lost my cycle at age 42 while doing heavy volume triathlon training while following a low carb vegetarian diet (stupid, I know). I got very lean. Dr. figured it was related to low body fat. Now almost 4 years later, it has not returned - I cont. to train heavily but BOOM! put on almost 10# even though I made no changes to my regimen. Now doc says it's menopause. My FSH wa 34.8 (menopausal) but my LH was low (7.2). I've tried to research but, from what I can tell, the levels are usually either both high or both low. Do my results mean anything? Todd asks: I switched gyms and have gone from chlorine pool to saline pool. I find my times are better and swimming seems a bit easier. Is this because of saline buoyancy? Gerry asks: Hi Ben, my best half marathon time to date is 95 min. However, in a 70.3 race, I've struggled to go faster. My best there is 115 min. What's the most effective way to train to improve that half marathon time during a 70.3 race? I'd like to do it under 100 min without fatigue or cramps. Janet asks: I work out 30 min. every morning six days a week. My workouts are 1 minute hard resistance/ cycling with cadence of 55 or 60 with my heart rate getting up to max 180 beats followed by recovery for 1 minute with cadence of 50 or 60 and heart rate around 150. Workout Is 30 min. Could you give me some ideas for other spinning workouts I could do? Can my body get too accustomed to this? Mike asks: I recently passed a kidney stone. My urologist had me do a 24 hr urine test, which showed high urinary calcium and oxalate. He has recommended I avoid Vitamin D supplementation (I'm currently taking 3000 IU daily), as well as decreasing coffee, cola, chocolate, nuts, spinach and green leafy vegetables. I don't drink cola and only 2 cups of coffee/day, but I really don't want to give up my big salad, handful of nuts, and small piece of dark chocolate. I've researched other "high oxalate" foods and it's a lot of otherwise very healthy foods that I love! What can you suggest for eating healthy while maintaining a "low oxalate" diet. Tony asks: I have recently finished my first 1/2 marathon, and my first Biathlon. My partner and I are signing up for a trail marathon in October. We are both in good shape and are dedicated to being better. I am a professionally diagnosed genetic hypertension person. I take two tablets each morning so that I will not stroke out. They are Procardia and Hyzaar. As I train, how should I approach supplements? What type of drug interactions do I need to be aware of? Melanie asks: Melanie asks: Hi Ben, What do you know about D-ribose? A health and fitness person that I follow sometimes said he just completed his own trial of ribose after being sent a sample and said after one week he felt a big difference in his energy level. Wondering if this is a good option to increase energy and what the drawbacks might be? Carlos calls in and asks: I am just a beginning amateur runner and am wondering if "regular" Multivitamins and Protein will be detrimental to my health. I hear you mention a lot of things about regular multivitamins and other regular supplements, but you never recommend them. Are they actually unhealthy for a beginner like me? By "regular" I mean, the more popular & affordable supplements used by a greater number of people such as products by Nature Made, GNC, and Optimum Nutrition. Are the supplements you recommend specifically for triathletes? My health is no where near a triathlete. Do I still need to take these "special" supplements or am I good taking the regular ones? I heard from another source I trust, that the differences between "special" and "regular" supplements are slim, and unless you are professionally training, the slightly higher benefit from taking special supplements is not really needed. -------------------------------------------- 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!

Weekend Special Update: "How To Grow a Healthy Baby"

Weekend Special Update: "How To Grow a Healthy Baby"

In this September 27, 2009 free audio weekend update, Ben has a special guest on the show to discuss how to grow a healthy baby. Here is the letter that accompanies this episode, written by Jessa Greenfield from Bud Organics: "For the past six months, Marta Greenfield and I have been developing a fresh, new and exciting idea.  We have been working very hard on a business plan, marketing strategy, community surveys, focus groups and many hours of due diligence – and we now feel that we are ready to unveil this business and our product to you. The organic industry has grown by over 20% in the last three years, while the commercial food industry has suffered as consumers become more aware of where and how their food is grown.  Along with this growing trend, many parents are becoming aware that commercial baby food is not the best way to feed their babies.  Every parent wants the best for their baby, and it is becoming more apparent that what is on the shelf right now is not the best, and could actually be harming a baby’s fragile body. I experienced the same feeling as I searched for the right baby food to grow healthy bodies for River and Terran. I learned that the common method of preserving baby food is canning.  The problem with this is that the food is heated to a very high temperature to kill the bacteria that cause botulism. This heating method kills much of the nutrition in the food. An inspection of the ingredients in all the commercial baby foods revealed the presence of genetically modified organisms (GMO’s), which are crops generally made up of corn, soy, cotton and sugar beets. These have been linked to allergies, asthma, digestive ulcers, learning disabilities, cancer, low birth weight, infertility and antibiotic resistance! I didn’t want these for River and Terran, especially since most of the world has banned GMO’s based on multiple research studies. The baby food found on the shelves of most grocery stores is comprised of fruits and vegetables that were picked several months before ripeness, rendering the food tasteless and deprived of nutrients. Furthermore, harsh chemical preservatives are necessary to keep the food for many months as it is shipped around the country (typically grown hundreds or thousands of miles from the economy where it is finally purchased), and nutrient-stripped “fillers” such as corn, soy and wheat are added to thicken the product. Many of the pesticides found in non-organic commercial baby foods contain probable human carcinogens, neurotoxins and pesticides that disrupt the normal functioning of the hormone system, and some of the pesticides are considered “Category One”, which is the highest designation of oral toxicitiy. A 2003 Washington University study found that babies who were fed organically had six times fewer pesticides in their urine than those that were not fed organically! I learned that A) much of an infant’s digestive and neurological development happens in the first 2 years of life; B) an infant’s body is less efficient in eliminating toxins; and C) an infant’s digestive tract absorbs much more than an adult’s. This was the final straw. Our goal for River and Terran was to raise them in as healthy a manner as possible, and commercial baby food was obviously not the solution, for their well-being, for our local farmers, or for any of the other mothers in Spokane, Coeur D’ Alene and across the United States. So after countless hours spent in the kitchen, on farms, in the library, in grocery stores and with mothers from across the region Marta and I have established a solution: Bud Organics. In sum, Bud Organics will be a producer of frozen organic baby food. But what is most important to Marta and I is to provide an affordable, quality alternative to commercial baby food to as many babies as possible.  We want to give these vulnerable young bodies the best possible start they can get.  That means that their food should be incredibly fresh and 100% free of pesticides and GMO’s, with zero “nutrient-void” fillers, preservatives, and chemicals. How are we going to ensure this? We have established a relationship with farmers within a 200 mile radius of the Spokane and Coeur D’ Alene area. A majority of our produce will be bought locally from these farmers.  The reason for this is two-fold; 1) it helps with our local economy and our money stays in the area, supporting a sustainable region; 2) our food will not be picked months before ripeness, and shipped across the world, which would leave it tasteless and nutrient deplete. To ensure freshness, our food will be picked at the peak of ripeness and processed immediately in our certified organic kitchen in Spokane.  All the produce used will be “certified organic”, which ensures that there are no pesticide or herbicides sprayed on the produce that goes into our product. Not only will none of the common “filler” ingredients like flour, soy and corn appear in our food, but because our produce is organic, there will be no GMO's. We have also established a relationship with several local grocery stores (both commercial and organic), farmer’s markets, mother’s groups and baby stores who are anxiously waiting for the first line of Bud Organics to hit the market. And the unique method of preservation? We can ensure our product is more nutritious to our counterpart because we freeze our product. Freezing still gives a six month shelf life, but doesn't kill any of the food components, and instead locks in the valuable nutrients until the product is naturally thawed and ready for the baby to eat! The combination of frozen, fresh and organic baby food is a unique concept with a massive market, as the numbers in our business plan and market analysis have proven to us. We want to ensure that we fund farms that are growing and helping the local environment that we are leaving to our children.  Organically grown produce is a sustainable method of farming.  Rather than stripping the land of nutrients, organic farming grows soil by composting and applying natural matters (not chemical), planting poly-culture crops and letting their land “rest”. “But,” you may say, “My mom fed me non-organic food when I was raised and look at me!” That is very true, but today many weeds and pests have built up a resistance to the growing use of herbicides and pesticides, so more sprays have to be applied than what was needed 10, 20 or 30 years ago.  Also the FDA has said that the levels of pesticides and herbicides on commercially grown produce is OK for the adult consumer, but they have not taken in to account young children and infants.  Ultimately, there is a growing need for an alternative to commercial baby foods, and Bud Organics can be that alternative that parents are desperately searching for, exactly as I did. Despite knowing the danger that their baby faces, not every parent will be able experience what I experienced: spending hours at local farmer’s markets and then in their own kitchen, preparing, mixing and freezing their own organic, frozen baby food. And Bud Organics is the solution. Marta and I hope that you all find this as important as we do.  We have discovered that we find no better calling in life than to help our future generations grow up healthy and in a better, cleaner environment and economy. That is why we are asking for your help.  Currently, this idea only exists “on paper”, and to the small batches that we have provided to local mothers, who are calling us for more! To make Bud Organics a physical, tangible, vibrant living business, we will need funding. We would rather go to our friends and family first, because you are the people that we know and who have shaped us into what we are now. This letter is our plea for a little assistance to begin helping America grow healthy babies. In launching Bud Organics, the cost of commercial kitchen, produce contracts, marketing materials, certifications and licensing, production and delivery methods can add up quickly, and this is our primary hurdle to turning this viable idea into a growing enterprise. Rather than overwhelming you with our 27 page business plan, we would simply like to know if you are interested in helping, and we can provide you with any of the business, marketing and revenue details at that point. Thanks for all your love, your support and your hope that we can make a lasting positive impact in this world." Bud Organics is currently raising capital to launch the first line of organic frozen baby food! Just call Jessa Greenfield at 208-301-4732 or e-mail jessa@budorganics.com if you are interested in investing in America's future.See omnystudio.com/listener for privacy information.
