    There is a certain bias and scepticism every time a new product is brought out.

    LED lighting, light emitting diodes, is an extremely efficient means of lighting, both in terms of light intensity and energy consumption.

    If humans have become used to getting there near infra-red from lighting then maybe it is their sedentary lifestyles that are to blame. Get out and get some sun and let the rest of us reap the benefits of efficient lighting and reduced strain on our energy production systems.

    CFLs, compact fluorescent lighting, is a health hazard and always was. I was always against it and was quite verbal about it.

    To the best of my knowledge LEDs are safe. They are still digital in nature, being a diode, but they do not emit radio signals and they do not flicker at a high rate beyond the perception of humans (which can cause epileptic fits and other brain disorders).

    Must I now research LEDs too, to make sure I have my facts straight? I don't like sensationalist news, it is time consuming and often misleading and inaccurate.

    "warm" led's have a decent spectral foot print.. not enough "near infra red" but still not bad for you... just don't get the "cool" ones.

    Yes.
    But I have been actively promoting these wonderful lights to my customers. Now I will bear the brunt of their ill health Karmically.

    And I have been experimenting with various light designs. Just finished one yesterday...

    edit: LED tape is a long string of LEDs up to 100 feet long. It can take any shape and is not restricted to a "volume" to contain the bulb...

    My take on this (which I am not all that confident of, to be honest) is that the primary problems here are the potential absence of enough near infra-red light in common LED lights, and the excess exposure to the higher frequency blues and violets for some sleep period of many hours, each day (night).

    So it seems to me that it should be sufficient to:
    1. Supplement LED lighting, if one is spending most of ones time in such lighting (as I am, sitting at an LED backlight computer monitor for eons at a time), with the sorts of infra-reds common in grow lights (e.g. Superdream 10W Full Spectrum Led Grow Light), and
    2. keep light (esp towards the blue/violet end of the spectrum) out of one's eyes while sleeping.
    This should cover most of the problems being considered here.

    I don't find LED lights "bad" for what they do, but "deficient" in a healthy portion of the spectrum, which can be compensated for.

    I don't know, yet anyway, of a reason to be concerned with EMF emissions from LED lights, and I'm not aware that these lights have any reason to be pumping the sort of higher frequency emissions, at the microwave level or up, which are the frequencies I worry about more (unless, that is, you have a "smart" LED light that is talking to your wi-fi hot spot, and helping hackers to run DDOS attacks on major websites.)

    The beauty of the LED is that it consumes almost no power. Since it is produced on a micro-chip, it takes only 4.5 volts DC to activate one such light.

    Also, it is incredibly cheap: one can order enough LED tape light and power supplies from China to light one's entire home for under a hundred bucks. And the payback is phenomenally fast in the form of reduced energy costs. The prodigious increase in cost in first world markets, by a factor of about 300%, is primarily simply mark-up. They can be circumvented by knowing where to order and from whom.

    Also, if ones knows the components and their stats, one can find unrelated parts from other areas not related to the LEDs themselves (a power source is a power source for example).

    They can easily interchange from house to car to pocket, if designed correctly, and with a bit of ingenuity.

    Very versatile, cheap, efficient and effective - it would be shame if they were also a health hazzard

    This subject comes up periodically on Avalon.
    When it does, I always recommend Full Spectrum light bulbs which I've been buying from Dr. Mercola's website for several years now and really like them.
    They last a long time, don't cost a lot, DON'T have the high level of mercury in them like other CFLs, though they look the same.
    They aren't hard on your eyes or your brain, good for SAD, and great for indoor plants.
    See:
    http://products.mercola.com/light-bulbs/
    PS Carmody checked them out and thought they looked good.

    Correction: OOps! I left out the DON'T before!

    Sounds like the start of an informative thread... I'd rather light my house for ~ 100 than continue paying Home Depo some ~250+ for just one light fixture (and one of those.. half the LEDs died in it!!)

    Like any business, prices never go down.

    So, if a lighting manufacturer has been used to a profit of say $100 million, they will still want to have that profit with LEDs.

    So far what I have noticed is that LED lights are being sold at the same price as other forms of lighting. Even though at those levels the profit margin is far higher. An LED source for a normal fixture of 60 watt equivalence costs pennies, not dollars. That's a hundred times less, or two full orders of magnitude!

    The enclosure costs remain the same but that is because of people's narrow tastes, that take time to change - they have to see it at the Jones' first. Enclosures for LED lights could be brought down by a factor of ten because LEDs use safe voltages not regulated by electrical authorities and they produce so little heat. But people have to rethink lighting all together to reap the rewards. For example: the pot light. The pot light has become a mainstay in the residential and even commercial markets. It was designed for use with the incandescent bulb and became smaller in diameter as the bulbs became more efficient and compact. But a pot light is inefficient in terms of lighting a room. Half its light is wasted in the can and the other half beam directly downward, leaving the top third of most rooms dark. Place an LED fixture of the same diameter in the same hole as the pot light and see how bright the room becomes! That is because all the light from the LED is at the finished surface and available for illumination at every level of the room. Such a fixture costs one quarter the price of a conventional pot light.

    Lighting could be more unobtrusive and yet more opulent at the same time because of LED lighting technology. Anything can be lit for pennies: railings, steps, door frames, counters, eaves, roofs, walls ceilings - anything.

    Here's 300 (lower power) LED's for $12 - retail: http://www.newegg.com/Product/Produc...9SIA7C93U19033.

    Or similar, with apparently somewhat higher power for $22: http://www.newegg.com/Product/Produc...9SIA77Y3TF0459

    Custom PC builders are having fun lighting up the insides of their computer cases with LED strips.

    How that compares with what you know of, Ernie, I don't know.

    That's comparable to what I have seen. I have third party information about cheaper prices I haven't tried yet myself. I think they have problems at customs sometimes.

    Importers are upping the price substantially so you have to have a source in China proper.

    I've heard of 100 ft. of tape light for $25. And 12W power packs for $2. I've installed these items for customers that quoted these prices. Maybe they exaggerated. If I was to buy the same thing from my supplier it would cost me about $125! Plus tax. A power pack approved for use in Canada costs about thirty dollars!

    There is no difference in the parts, it is the CSA sticker (the approval, like UL in the States) that costs the extra. Same with the tape light. It is a combination of the regulating bodies and the manufacturers that jack up the price, like always. We don't see it because they do it with everything, all the time so we are inured to its omnipresence.

    LEDs are also very good in combination with solar power or wind because the voltages are the same and don't require an expensive inverter to convert from DC to AC power. In other words, you can plug your LED strip lights directly to your solar cell and they will light up.

    How Therapeutic Use of Full-Spectrum Light Can Improve Your Health
    February 05, 2017
    http://articles.mercola.com/sites/ar...rid=1872564168

    Quote By Dr. Mercola

    Photobiology is the therapeutic use of light to improve health. In this interview, Dr. Alexander Wunsch, one of the leading experts in photobiology, explains the historical significance of photobiology.

    I recently interviewed him about the dangers of light emitting diode (LED) lighting. That interview has nearly three-quarter of a million views at this point. If you haven’t seen it already, please take a look, as that interview went into some very practical, real world aspects of photobiology.

    Here, we focus on the historical component to help you get a better appreciation of its potential.

    Historical Use of Light Therapy

    Light has been used therapeutically for thousands of years. Humans have not only evolved to adapt to sunlight, but also to the influence of fire — near-infrared and mid-infrared radiation that is very low in in the blue range wavelengths — which is also emitted by incandescent light sources.

    In ancient Egypt, we know that sunlight was used for hygienic purposes, and once humans began manufacturing glass, it also became possible to produce colored light using the colored glass as filter technology.

    An important point that needs to be made is that the human retina is not designed to be exposed to blue light at night. We were ever only exposed to fire light at night. This is why it’s so crucial to block blue light, particularly at night, but also during the daytime when the light is from artificial sources.

    Incandescents and halogen lights are acceptable, as they contain the near-infrared wavelengths, while LEDs are best avoided, since they’re virtually devoid of these healing near-infrared wavelengths, emitting primarily blue light.

    Around the turn of the 18th century, light began to be used therapeutically to treat illness.

    “I call the time before the 18th century the “mystical phase” of light use, because humans already had clear indications that light does them good, but they didn’t explore it in a scientific manner,” Wunsch says.

    “In the 18th century — we also call it “the age of enlightenment” — people became much more interested in the reasons why the occurrences happen around them.”

    The First Phototherapeutic Device

    Andreas Gärtner, known as the “Saxonian Archimedes,” built the first phototherapeutical device. It was a foldable hollow mirror made from wood and plaster, covered with gold leaf.

    Using this, he could concentrate sunlight onto aching joints of patients. People suffering from arthritis, rheumatism and gout found pain relief from this phototherapeutical unit.

    Today, we can explain how this device worked without causing a phototoxic reaction or burns. The gold leaf actually absorbs all of the ultraviolet (UV) radiation from sunlight, emitting luminous heat rays in the near-infrared and red wavelengths, which is beneficial because it can penetrate deeply into the tissue.

    “It’s interesting that UV behaves quite peculiar in combination with certain metals. For example, silver only reflects about 4 percent of the incident UV radiation. Gold almost absorbs all the parts. The best reflector for UV is aluminum.

    When we talk about phototherapy, besides the heliotherapeutic application, we always have to look at the light source, and we have to look at the beam shaping media, such as the reflector or lenses, because they all contribute to the final blend of wavelengths, which then come into action in the phototherapeutical intervention,” Wunsch explains.

    The Science of Light in the 19th Century

    In the late 19th century, we started gaining a great deal of knowledge about how light acts on the human body. It started with the experiments of A. Downes and T.P. Blunt, who discovered that UV radiation kills bacteria. Researchers were also interested in other parts in the optical spectrum.

    General Augustus Pleasanton published “Influence of the Blue Ray of the Sunlight” in 1876 in which he described experiments performed between 1861 and 1876.

    He grew grapes for wine, using not only transparent colorless glass, but also blue window glass. With the latter, he got a significant increase in plant growth. Later, he performed similar experiments on humans.

    “People in the late 19th century, especially in the United States, would walk around with blue glasses. In a way, they did exactly the opposite of what we do today to protect our eyesight.

    They even enhanced the blue part of the spectrum because they used it as a kind of booster, a kind of doping, and didn’t care about the long-term effects, which are pretty negative …”

    Wearing blue-colored glasses increases the blue exposure and limits the red and infrared.

    The problem with that is that while short-term use of blue-enriched light has an activating effect, you can quickly develop a tolerance and, long-term, the stimulating effect is harmful to your biology. Hence wearing blue-tinted glasses on a daily basis is not a good idea.

    “You can use them for a few minutes. This can be a good idea. From today’s scientific viewpoint, we need at least one hour of unfiltered daylight [each day] during adolescence in order to prevent myopia. But it’s not pure blue, and not pure blocking. Somewhere in between is the golden pathway to health.”

    Reinventing the Wheel

    The same year Pleasanton published his book on blue light experiments, Dr. Seth Pancoast published “Blue and Red Light: Light and Its Rays as Medicine,” covering both blue and red light experiments.

    Pancoast understood the antagonistic effect of red and blue light, using red light to stimulate sympathetic activity and blue light to stimulate parasympathetic activity.

    A year later, in 1878, a year before Edison invented the incandescent lamp, Dr. Edwin Dwight Babbitt published “Principles of Light and Color.” He used the full set of rainbow colors discovered by Newton, and later on used the color set of Goethe. The book is about 800-pages long, but for those with an interest in photobiology, it’s a treasure trove.

    “Today in medicine, we start to reinvent what they already knew or what they already found out in the late 19th century — that the colors have specific effects on our health, on our organism. Using the correct colors means you can communicate with all your different organs in your system,” Wunsch explains.

    According to Wunsch, Babbitt’s tome covers everything we’re currently rediscovering about photobiology and phototherapy. Babbitt even presented information about how atoms are frequency and oscillation. With regards to the use of colored light, Babbitt used a kind of bottle shaped as a lens.

    By adding a salt solution, he produced different colors. He then focused colored light on different parts of the human body. Like Pleasanton and Pancoast before him, Babbitt produced therapeutic results using colored light.

    “The problem was that it’s very difficult to reproduce these effects, starting with the problem that the sun doesn’t always shine,” Wunsch says. “They were pioneers in chromotherapy in a time where electrical lighting was not available.

    People, in a way, had better circadian rhythm without electrical lighting. But in terms of scientific precision with regard to producing colored light, they had worse conditions than we have. Today, we can exactly produce the same colors anytime, during the day and during the year.”

    Treating Disease With Light

    In 1897, Dinshah Ghadiali, an India native who lived out the second half of his life in the United States, rescued the life of a patient using Babbitt’s instructions. The patient had colitis, an inflammatory disease of the intestines. Dinshah knew, from reading “Principles of Light and Color,” that indigo colored light could stop vomiting and break the disease process.

    This started a new chapter in chromotherapy, and Dinshah experimented with colored light for more than 23 years before he presented his system to the public. Another chromotherapy pioneer during the late 19th century was Niels Ryberg Finsen in Denmark. He was the first to make a discrimination between negative phototherapy and a positive phototherapy.

    He used a very specific red light to treat small pox patients. He removed the short wavelength part of the spectrum, especially the ultraviolet, violet, indigo and blue, leaving the colors located in the longer wavelength of the light spectrum.

    “You can be 100 percent sure that if you paint a room completely in red and you’re using red curtains and red tissue or cloth, that you would have 100 percent elimination of blue. The short wavelength part, the blue and the indigo, was the reason for the inflammatory reaction in patients with small pox,” Wunsch explains.

    Finsen … reinvented the negative phototherapy, which means you eliminate certain parts of the spectrum, which would exaggerate the development of a disease … This observation — that the short wavelength in the spectrum would amplify the inflammatory reaction in small pox — led him to the idea that light acts as an incitement. It is able to produce the inflammatory reaction. In small pox, this would be a problem. But he was thinking about the treatment of tuberculosis.

    In treating tuberculosis, his idea was if he could produce the inflammation in the tissue, then the body would be able to cure itself. This is what he finally developed: the positive phototherapy, which means he produced exactly this part in the spectrum he formerly wanted to exclude. Using the short wavelength part enabled him to very successfully treat tuberculosis, especially in the skin … His idea was to use electric light …

    In the late years of the 1890s, he established the Finsen Institute in Copenhagen and successfully treated patients with tuberculosis from all over the world. He was awarded the Nobel Prize for Physiology in 1903. This was one of the most important persons in the end of the 19th and the beginning of the 20th century.”

    Phototherapy Becomes State of the Art Medicine

    Finsen’s work fueled the progress of phototherapy for the next several decades. From 1900 to 1950, phototherapy was a state of the art therapeutic intervention in medicine. Remember, Finsen effectively treated tuberculosis nearly 50 years before the advent of pharmacological medication. There really was no treatment for tuberculosis prior to light therapy. Tuberculosis is a very slow-growing organism that is hard to treat. Today, patients are typically given multiple drugs to treat it.

    The reason light works for tuberculosis is because UV light is germicidal. This is one of the reasons why it’s useful to hang your clothes to dry outside. Exposing your laundry to sunlight kills bacteria, viruses and other microbes that might contaminate your bed linens and clothing.

    The easiest way to benefit physically from the light therapy provided by the sun is to expose your bare skin to the sun on a regular basis, ideally daily. Most people rarely ever expose more than their face and hands to the sun. Indeed, one of the most important points I want to make here is that lack of exposure to sunlight can have some really serious adverse consequences for your health.

    In the late 19th century, John Harvey Kellogg invented a phototherapeutic method using red and the near-infrared rays (the luminous heat rays). He founded the Battle Creek Sanitarium, where he performed heliotherapy on patients as early as 1876. In 1891, shortly after the invention of the incandescent lamp, he filed a patent for an incandescent light bath. In the following two years, he treated thousands of patients with this light.

    Kellogg exhibited his incandescent light bath system at the world exhibition in Chicago in 1893, where it caught the attention of German chemist Dr. Willibald Gebhardt. Gebhardt visited Kellogg at the Battle Creek Sanitarium, where he learned all about its use, and then brought the technology and knowledge back to Berlin.

    Over the next few years, Gebhardt established hundreds of light institutes throughout Germany, treating psoriasis and pain associated with gout and rheumatism. These institutes were so successful they even posed a threat to the medical community, as doctors could not provide better relief than what people were getting from self-treatment at these light institutes.

    Light Therapeutics

    In 1910, Kellogg published a text book called “Light Therapeutics.” It’s a seminal work that has stood the test of time, being as valuable and revolutionary today as it was back then, if not more so, considering all the knowledge we’ve lost and are just now rediscovering. You can download the book for free at the link above. It is a great read to see what he was doing more than a century ago.

    “I really would recommend this [book] to everyone who is interested in phototherapy, because this is the basic knowledge. Everything you have to know about sunlight, ultraviolet light, visible light, the near infrared, about the use of cold, the use of heat — it’s all contained in this book from John Harvey Kellogg,” Wunsch says.

    “It’s still, in my understanding, the first book to read if you want to understand how light in the different parts of the spectrum interact with the organism. It’s very systematically structured … For example, everyone warns you about sunburn, but in the pre-antibiotic era, the medical doctors sometimes had to completely change the direction in a patient … Here, sunlight was one of the therapeutic options.

    I would not recommend to use this today, but Kellogg describes in detail the four different stages of a sunburn. The first thing that he says is ‘Sunburn is not a burn injury. A burn injury appears immediately. And a sunburn appears with delayed time of several hours.’

    He didn’t know anything about reactive oxygen species these days, but he exactly explained that there is definitely a huge difference between an immediate heat-induced burn and a kind of phototoxic reaction that you find in a sunburn.

    He discriminated or described four different stages of a sunburn from one to four. Four is with blisters. One is just the mild erythema. In those days, without antibiotics, sometimes [they] deliberately chose to induce a second degree or third degree erythema in order to change the direction of the development of the health of a certain patient.”

    Heliotherapy During Surgery

    Dr. Oscar Bernhard, a Swiss surgeon, even used heliotherapy (i.e. sun therapy) during surgery. Bernhard was actually using sunlight even before Finsen inaugurated and popularized his method. At this time in the late 19th century, it became apparent that as people moved from the country to the cities, rates of rickets and tuberculosis rose. It became increasingly clear that lack of sunlight had something to do with it.

    Bernhard, who lived and worked in the Swiss mountains near Davos, would place his surgical patients in direct sunlight for 10 to 15 minutes, just before closing the wound. He found this significantly improved wound healing. Another Swiss “sun doctor” was August Rollier, who began treating patients using sunlight in 1905. In the 1930s and ‘40s, he ran up to 40 different hospitals in Switzerland.

    “Rollier only used heliotherapy,” Wunsch says. “He was convinced that artificial light cannot do the job, and that sunlight is superior. Rollier was the master of heliotherapy in these days up to the 1950s … He was treating patients [with heliotherapy for] more than 50 years, from the beginning to the mid of the 20th century …

    He was a holistic physician who not only used sunlight in a very skillful manner, but also all the other options, using music and a kind of physiotherapy or work therapy. He invented a lot of different appliances, which enabled the patient to lie in their bed and do some work and be productive …

    This was very important for people suffering from tuberculosis being treated in Switzerland, because it was quite expensive to stay there as a patient … He had very good results — much better compared to what we expect from tuberculosis treatment using the five-phase antibiotics treatment we have nowadays.”

    This isn’t so surprising when you consider that UV light is directly germicidal to many microbes, and UVB exposure specifically helps your body produce vitamin D. In fact, vitamin D is a biological marker for UVB radiation exposure. When your body has enough, your vitamin D levels go up.

    Why Vitamin D Supplements Cannot Fully Replace Sun Exposure

    Today, many simply resort to taking a vitamin D supplement, but it’s naïve to believe you’re going to get the same benefits from an oral supplement as you would from UVB exposure. Your body is designed to produce vitamin D in response to sunlight, not through oral intake. I’m not saying you should avoid vitamin D supplements. If you cannot get enough sunlight, that’s your next best option. But the goal is not to raise your vitamin D through swallowing a pill. As Wunsch explains:

    “[I]f you administer vitamin D orally, it signals your system that you have lots of UV around you. This might even start processes that are not adequate because your skin didn’t actually have the exposure. I think the best idea, if you have the skin type so that you can stand sun exposure, is that you use this natural pathway [i.e. sun exposure]. Because then you have coordinated, coherent action pathways, which are not granted [otherwise].

    Another aspect that is still unclear is if orally administered vitamin D really reaches the skin layers where you normally need it as well, in the keratinocyte layer. Cathelicidin is a substance produced under the influence of vitamin D in the skin, which helps the organism to fight germs. This might be one of the reasons why the heliotherapy and the UV therapy were so efficient with regard to tuberculosis treatment.”

    Candles — A Healthy Light Alternative

    Candles are even better light sources than incandescent bulbs, as there is no electricity involved and are the light our ancestors have used for many millennia, so our bodies are already adapted to it. The only problem is that you need to be careful about using just any old candle, as most are toxic.

    As you may or may not know, many candles available today are riddled with toxins, especially paraffin candles. Did you know that paraffin is a petroleum by-product created when crude oil is refined into gasoline? Further, a number of known carcinogens and toxins are added to the paraffin to increase burn stability, not including the potential for lead added to wicks, and soot invading your lungs.

    To complicate matters, a lot of candles, both paraffin and soy, are corrupted with toxic dyes and fragrances; some soy candles are only partially soy with many other additives and/or use GMO soy. The candles I use are non-GMO soy, which is clean burning without harmful fumes or soot, is grown in the U.S. and is both sustainable and renewable. They’re also completely free of dyes. The soy in these candles is not tested on animals and is free of herbicides and pesticides.

    It's also kosher, 100 percent natural and biodegradable. The fragrances are body safe, phthalate- and paraben-free, and contain no California prop 65 ingredients. You can search online for healthy candles, but if you like, you can use the ones I found at www.circleoflifefarms.com. This is not an affiliate link and I earn no commissions on these candles; I just thought you might benefit from the ones I now use in my home.

    How to Make Digital Screens Healthier


    When it comes to computer screens, it is important to reduce the correlated color temperature down to 2,700 K — even during the day, not just at night. It’s even better to set it below 2000K or even 1000K. Many use f.lux to do this, but I have a great surprise for you as I have found a FAR better alternative that was created by Daniel Georgiev, a 22-year-old Bulgarian programmer that Ben Greenfield introduced to me.

    He was using F.lux but became frustrated with the controls. He attempted to contact the F.lux programmers but they never got back to him, so he created a massively superior alternative called Iris. It is free, but you'll want to pay the $2 and reward him with the donation. You can purchase the $2 Iris mini software here.

    Iris is better because it has three levels of blue blocking below f.lux: dim incandescent, candle and ember. I have been using ember after sunset and measured the spectrum and it blocked nearly all light below 550 nm, which is spectacular, as you can see in the image below when I measured it on my monitor in the ember setting. When I measured the f.lux at its lowest setting of incandescent it showed loads of blue light coming through, as you can clearly see in the second image below.

    So, if you are serious about protecting your vision you will abandon f.lux software and switch to Iris. I have been using it for about three months now, and even though I have very good vision at the age of 62 and don't require reading glasses, my visual acuity seems to have dramatically increased. I believe this is because I am not exposing my retina to the damaging effects of blue light after sunset.

    More Information

    Wunsch, who has studied photobiology and light therapy for decades, understands the influence of light on health perhaps better than anyone. Having this historical grounding will hopefully help you understand some of these benefits, and inspire you to apply heliotherapy in your own life. All you have to do is step outside and take some clothes off. There’s no question in my mind that sun exposure is as important — or nearly as important — as eating a healthy diet and exercising.

    Unfortunately, virtually no one is talking about or teaching this. The point is, they did in the past. We’re now rediscovering what was common knowledge 100 years ago! Sadly, the pharmacological focus has created an enormous, manipulated bias, which essentially directs most of the research.

    If it was authentically and sincerely motivated, based on specific healing principles, we would have expanded on the research into heliotherapy and photobiology. The reason we haven’t is because it’s been artificially suppressed. That’s the sad reality.

    The good news is that this is the 21st century — a time when we have access to extremely powerful methods of communication, allowing us to share this information with literally millions of people. By doing so, we can create a foundation of a new understanding, thereby catalyzing research and therapeutic interventions that can help us avoid the expensive and toxic interventions typically recommended for diseases that respond perfectly well to interventions such as light.

    It’s truly so simple. Take myopia for example. We’re now realizing that nearsightedness is closely linked to lack of sun exposure, especially during childhood. — not a lack of vitamin D, mind you, but a lack of natural sunlight striking the eye. If you missed my article on preventing myopia with sunlight, please take a moment to check it out now.

    Understanding this connection, and doing something about it — sending your kids outdoors for at least an hour a day — could help prevent this extraordinarily common vision problem without costing a cent.

    My partner made me a DIY home infrared sauna. There are so many benefits and it has really helped my health. I do about 20 minutes a day (longer in winter). Would this counteract the downside of LED? http://empoweredsustenance.com/near-...auna-benefits/

    I've been getting 1/2 hour infrared treatments on a Jade Fuzion mat once a week at my physical therapist, and it's really been helpful.
    I'm looking at getting a less expensive one for home.
    It makes it much easier to get through the cold and damp winter days!

    I've often thought of humans as an entropic force, we confine chaos and impose order on all that we can control, we take natural substances and concentrate them to levels that are toxic to anything else...are we the bad guys that don't know / can't admit they are "bad-guys"?.

    But perhaps it's understanding/knowledge that is the "culprit", interesting concept. (especially when taking in the biblical stories.. tree of knowledge/paradise lost etc..)
