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:

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. In the meantime, leave your questions, comments and feedback below...

Ben Greenfield's Favorite Workouts, Building a Generational Legacy, Biohacking On a Budget, & Much More: Part 2 of Ben's Talk at the Health Optimisation Summit.

BenGreenfieldLife.com/hospodcast2 Today's episode is Part 2 of my talk at the Health Optimisation Summit, recently held in London by noted UK biohacker and media personality Tim Gray. The Health Optimisation Summit brings together the best from all the key diets, and everything in the health, wellbeing, medical, nutrition, biohacking, and fitness worlds, with the view not to push one mindset, but to incorporate them all with the sole goal of making people healthier–using whichever mindset or 'diet' is best for the individual. When I interviewed Tim Gray recently, on the podcast episode "How UK’s Leading Biohacker Eats, Drinks, & Optimizes His Life: An Interview With Tim Gray," I got a sneak peek into what his life looks like, from his fitness and nutrition routines to his sexiest biohacks. At this year's Summit, Tim turned the tables and actually asked me to present on "A Day in the Life of Ben Greenfield." At first, I thought I'd be struggling to fill the time slot with just my "average day," but then as I thought about all the hacks, routines, and rituals I do throughout my days that are now more or less automatic for me but likely something you'll be quite interested in, I realized it might not be quite as simple as it sounds! In this episode, we pick up where we left off last time, and go on to talk about the importance of family time at the end of the day, finishing the day with purpose, and we even had time left at the end to answer a few questions from members of the audience. Remember, if you haven't yet, I highly recommend you listen to Part 1 of this series, either before or after this episode! In this episode, you'll discover: -How Ben makes the most of the mid-day siesta... -Ben's favorite workouts throughout the day... -Building a family legacy... -Eating practices at the end of the day... -Bedtime rituals... -And much more!

The Nitty-Gritty Details Of Ben Greenfield's Daily Routine, How To Optimize Your Workspace, The Latest Biohacking Secrets, Superfood Smoothies & Much More: Part 1 of Ben's Talk at the Health Optimisation Summit.

BenGreenfieldLife.com/hospodcast1 Here, for your itching ears and supremely curious heart and mind, comes Part 1 of my talk at the Health Optimisation Summit, recently held in London by my friend and podcast guest, Tim Gray. The Health Optimisation Summit is Europe’s largest health conference, showcasing the best speakers from the health, biohacking, fitness, longevity, nutrition, functional, and preventative medicine spaces (including yours truly) in order to provide people with the knowledge, tools, and resources to take their own health and performance to the next level. The UK's leading biohacker, Tim Gray is known for his detailed tracking of more than 35+ biomarkers per day, is frequently in the mainstream media regarding practical, trackable, and immediately apply-able health hacks, and is featured on over 30 podcasts a year. As a psychology specialist and a successful businessman, Tim founded and invested in multiple 6-figure businesses, including digital marketing agencies and London’s first private Hyperbaric Oxygen Clinic. After years spent self-healing his body from chronic health conditions through biohacking alone, Tim Gray embarked on a mission to educate and empower the masses. Recently, I spoke to Tim about his history, his routines, the Health Optimisation Summit, and plenty more, in a special two-part podcast episode that included an interview and then a follow-up solosode by Tim ("How UK’s Leading Biohacker Eats, Drinks, & Optimizes His Life: An Interview With Tim Gray"). For this year's Summit, Tim actually asked me to present on "A Day in the Life of Ben Greenfield." At first, I thought I'd be struggling to fill the time slot with just my "average day," but then as I thought about all the hacks, routines, and rituals I do throughout my days that are now more or less automatic for me but likely something you'll be quite interested in, I realized it might not be quite as simple as it sounds! In fact, like I needed to do with Tim's podcast, I had to split my talk up and finish presenting about a "typical" day in Part 2, which is the next episode you'll see released on the podcast feed. You can also go here to get all of the resources from my talk at the Summit. Enjoy! In this episode, you'll discover: -Look at the body as a battery... -Ben's morning routine... -Family time in the morning and the morning smoothie... -How Ben optimizes his workspace... -Midday routines and rituals... -Audience question: "What does your wife do?"...

How to Love People & Use Things, Whether Or Not You're A "Hoarder," Minimalist Diets & Workouts & 7 Essential Relationships with Joshua Millburn.

https://bengreenfieldlife.com/minimalist I've been interviewed a few times on the outstanding Minimalists podcast with Joshua Millburn and his partner in crime Ryan Nicodemus, who together founded The Minimalists. This time it was I who put one of them on the hot seat for my podcast, and was able to speak with Joshua about his journey into the minimalism mindset, how we sometimes go about it the wrong way, the four stages of hoarding, and much more. At first glance, people might think the point of minimalism is only to get rid of material possessions: Eliminating. Jettisoning. Extracting. Detaching. Decluttering. Paring down. Letting go. But that’s a mistake. True, removing the excess is an important part of the recipe—but it’s just one ingredient. If we’re concerned solely with the stuff, we’re missing the larger point. Minimalists don’t focus on having less, less, less. We focus on making room for more: more time, more peace, more creativity, more experiences, more contribution, more contentment, more freedom. Clearing the clutter frees up the space. Minimalism is the thing that gets us past the things so we can make room for life’s important things—which aren’t thingsat all. In this interview with Joshua Millburn, you'll discover: -Publishing forays in the realm of minimalism... -The four stages of hoarding, and which stage you're likely at... -The "lightbulb" moment when Joshua embraced minimalism... -Starting points into the realm of Minimalism... -Ben and Josh discuss a minimalist diet... -Minimalist exercise and workouts... -Why being busy doesn't make you important, it just makes you busy... -The seven essential relationships in our lives to balance before focusing on relationships with other people... -How social minimalism promotes a life of productivity and creation... -And much more...
