Use of 660 nm
The deep red color of light (660 nm) has been in use for over 45 years. NASA was the first to truly research it's possibilities for medicinal purposes and further to learn it has healing effects.
This wavelength is currently used in hospitals world wide for burn treatment and surface treatment, in the form of complex laser based machines. The cost of these machines has been prohibitively expensive for personal use until now.
TenDlite - Higher Power LED Source
One of the reasons why the TenDlite is so effective, and what sets it apart from most devices which employ 660 nm wavelength, is its optical power output. NASA research found that an effective dosage for 660 nm is 4 joule of energy per square centimeter. The optical output of the TenDlite is 0.5 optical watt of output power, which is the equivalent of 0.5 joules of work per second. To give an idea of how that translates, the sun at peak time of the day for 4 hours produces 4 joules of work at the 660 nm wavelength. The TenDlite produces this same result in 8 seconds!
LED vs. Laser as a Source for 660 nm
The following are conditions known to be helped by LED light therapy
• Sports injuries such as knee, ankle, shoulder, etc
• Burns, scrapes, and pain relief from cuts
• Macular degeneration
• Laser burns to retina
• Fibromyalgia pains
• Preventing bruising and inflammation if it's fresh injury
• Bunion pain
• Diabetic neuropathy
• Myofascial pain
• Minimize recent nerve injury
• Wound healing, especially in diabetics
• Wrinkles, aging, acne and spots
• Fresh scars (4 months or earlier)
• Bone healing (it might help)
• Muscle ache from workout
• Existing bruises and inflammation
• Back pains
• Rosacea, psoriasis, eczema, dermatitis, poison ivy
• Joint pain relief
• and many more discoveries and been made but not published yet
Figures D and E displays a dramatic demonstration of a scar healing using the TenDlite in just one day of treatment.
In Depth Technical Information
The primary reason that LED biophotonic therapy improves surface body tissue is that the body tissue is able to absorb this light at the cellular level, and then convert the light into cellular energy. This increased cellular energy then causes the cell’s natural healing processes to occur at a more rapid rate. There are particular wavelengths which have been discovered which enable this to happen.
The red 660nm light “kick-starts” cells into creating more ATP (cellular energy) and increasing DNA and RNA activity. This effect has been carefully studied and researched in many published reports since 1987. The positive effects occur only in injured cells. The wavelengths from 600 to 900 nm pass pass through blood and water in tissue more easily than other wavelengths. Roughly 35% of the energy in this range is absorbed by a specific “proton pump” (cytochrome c oxidase, CCO, “complex IV) in mitochondria.
The light at 4 specific wavelengths “kick-start” the CCO pump into producing more cellular energy, ATP. The CCO pump is very similar in all animals because it evolved from light-assisted bacteria that were part of the first mitochondria. The absorption spectrum of blood (660 nm dominant region) suddenly drops off to allow these wavelengths to pass through which indicates the evolution of hemoglobin may have been influenced by cells benefiting from these wavelengths.
The immediate increase in respiration that sun causes by this mechanism may help animals increase their activity during the day, in addition to the heat provided by the sun that promotes the release of oxygen (myoglobin also absorbs these wavelengths). These wavelengths of the Sun can provide the optimum 4 J/cm2 at a depth of 1 inch (using 1% transmission) after 4 hours of exposure in bright Sun, reaching all skin and a large percentage of muscle tissue in historically-thin humans with minimal clothing.
In Depth Technical Information
As the CCO absorbs light, its two copper atoms are either oxidized or reduced to transport electrons that are required to help pump H+ to increase the gradient that allows for more ATP. This increases respiration (krebs cycle molecules provide the energy). Calcium Ca2+, alkalinity (0.2 units), and oxidation are increased which causes important secondary responses such as transcription factors that increase DNA and RNA activity.
Daily moderate use of light therapy induces up-regulation of antioxidants like MnSOD to counteract the harmful oxidation of O2- in a manner much like moderate exercise. Resveratrol has a similar action via SIRT1/NAD+ -->FOX3a-->MnSOD. Like Resveratrol and Nicotinamide, light therapy increases NAD+ which is known to increase endurance as well as increase MnSOD. Over the short-term, heavy exercise depletes NAD+ but light exercise increases it (ref). Light therapy increases GSH (glutathione) which decreases H2O2 that is produced from the extra MnSOD that is converting O2-22to H2O2. Too much wide-spectrum infrared light, such as that received from 3 hours of bright sunlight, causes too much H2O2 which will increase MMP-1 (at least in the dermis of the skin). The Solexis uses one wavelength therefore H2O2 will not increase.
The chemical NO is prevented from halting CCO activity and this may explain the immediate pain relief. More electrons being transported to create ATP oxidizes ("alkalinizes") the entire mitochondria, increasing the ratios NAD+/NADH, NADP+/NADPH, GSH/GSSG and signaling important secondary effects such as transcription factors which signal more DNA and RNA. The idea that 600 to 900 nm wavelengths activate cytochrome c oxidase was first proposed 20 years ago by Tiina Karu in 1988. See her 2003 great summary for more about light therapy and CCO.
CCO absorbs energy from the 600-900 nm photons and reflects them with a slightly longer wavelength (approx 50 nm longer), extracting about 0.1 eV of energy in helping to create 0.42 eV in a molecule of ATP. If CCO in the body is able to absorb 10% of the 1E17 photons/cm2 in the 600-900 nm range from bright Sun over 1 m2 of skin for 4 hours, then the human body has gained about 6 kcalories, making us 1.8% photosynthetic during those 4 hours. The light is directly photo-assisting in the creation of the ATP chemical energy.This does not include the calories absorbed from light that reduces the need for maintaining body temperature or required for cooling.
