Best red light therapy device
The second pathway that can occur is fluorescence. Fluorescence is a luminescence or re-emission of light, in which the molecular absorption of a photon triggers the emission of another photon with a longer wavelength. The energy difference between the absorbed and emitted photons ends up as molecular vibrations or heat. The wavelengths involved depend on the absorbance curve and Stokes shift of the particular fluorophore. The third pathway that can occur after the absorption of light by a tissue chromophore, represents a number of processes broadly grouped under an umbrella category of photochemistry. Because of the energy of the photons involved, covalent bonds cannot be broken. However, the energy is sufficient for the first excited singlet state to be formed, and this can undergo intersystem crossing to the long-lived triplet state of the chromophore.
Therefore, the ayurvedic energy of a "dose" of light depends only on the number of photons and on their wavelength or color (blue photons have more energy than green photons, that have more energy than red, that have more energy than nir, etc). Photons that are delivered into living tissue can either be absorbed or scattered. Scattered photons will eventually be absorbed or will escape from the tissue in the form of diffuse reflection. The photons that are absorbed interact with an organic molecule or chromophore located within the tissue. Because these photons have wavelengths in the red or nir regions of the spectrum, the chromophores that absorb these photons tend to have delocalized electrons in molecular orbitals that can be excited from the ground state to the first excited state by the quantum. According to the first law of thermodynamics, the energy delivered to the tissue must be conserved, and three possible pathways exist to account for what happens to the delivered light energy when low level laser therapy is delivered into tissue. The commonest pathway that occurs when light is absorbed by living tissue is called internal conversion. This happens when the first excited singlet state of the chromophore undergoes a transition from a higher to a lower electronic state. It is sometimes called "radiationless de-excitation because no photons are emitted. It differs from intersystem crossing in that, while both are radiationless methods of de-excitation, the molecular spin state for internal conversion remains the same, whereas it changes for intersystem crossing. The energy of the electronically excited state is given off to vibrational modes of the molecule, in other words, the excitation energy is transformed into heat.
leds as light sources was the next step in the technological development of light therapy, which is now applied to many thousands of people worldwide each day. In lllt, the question is no longer whether light has biological effects, but rather how energy from therapeutic lasers and leds work at the cellular and organism levels, and what are the optimal light parameters for different uses of these light sources. One important point that has been demonstrated by multiple studies in cell culture 3, animal models 4 and in clinical studies is the concept of a biphasic dose response when the outcome is compared with the total delivered light energy density (fluence). It has been found that there exists an optimal dose of light for any particular application, and doses lower than this optimum value, or more significantly, larger than the optimum value will have a diminished therapeutic outcome, or for high doses of light a negative. Evidence suggests that both energy density and power density are key biological parameters for the effectiveness of laser therapy, and they may both operate with thresholds (i.e., a lower and an upper threshold for both parameters between which laser therapy is effective, and outside. The reason why the technique is termed low-level is that the optimum levels of energy density delivered are low when compared to other forms of laser therapy as practiced for ablation, cutting, and thermally coagulating tissue. In general, the power densities used for lllt are lower than those needed to produce heating of tissue,. E., less than 100 mW/cm2, depending on wavelength and tissue type. Physical mechanisms, according to quantum mechanical theory, light energy is composed of photons or discrete packets of electromagnetic energy. The energy of an individual photon depends only on the wavelength.
The Therapeutic Effects of, red and near-Infrared, light (2015)
These effects in turn lead to increased cell proliferation and migration (particularly by fibroblasts modulation in levels of cytokines, growth factors and inflammatory mediators, and increased tissue oxygenation. The results of these biochemical and cellular changes in animals and patients include such benefits as increased healing of chronic wounds, improvements in sports injuries and carpal tunnel syndrome, pain reduction in arthritis and neuropathies, and amelioration of damage after heart attacks, stroke, nerve injury. History, in 1967, a few years after the first working laser was invented, Endre mester in Semmelweis University, budapest, hungary wanted to test if laser radiation might cause cancer in mice. He shaved the dorsal hair, divided them into two groups and gave a laser treatment with a low powered ruby laser (694 nm) to one group. They did not get cancer, and to his surprise kosten the hair on the treated group grew back more quickly than the untreated group. This was the first demonstration of "laser biostimulation". Since then, medical treatment with coherent-light sources (lasers) or noncoherent light (light-emitting diodes, leds) has passed through its childhood and adolescence. Currently, low-level laser (or light) therapy (lllt also known as "cold laser "soft laser "biostimulation" or "photobiomodulation" is practiced as part of physical therapy in many parts of the world.

This seems to be due to the micro-organisms already containing their own endogenous photosensitizer components, which our human cells do not. The red or infrared light supposedly interacts with these chemicals in the fungal cells, causing a destructive chain reaction that ultimately destroys them. Whatever the mechanism is, red light therapy alone is effective at clearing infections from a wide range of fungi and bacteria, in a way that even drug-resistant super strains cannot resist. The beauty of using red light to treat infections is that while the micro-organisms are being killed, your own skin cells are producing more energy/CO2 and so inflammation is reduced. Red light kills the infection, but strengthens you at the same time. Before, after, fig. Yeast cells growing on a nutrient plate. Red light being used to kill yeast in the lab at 685nm1-2.
This can be shown by how in the fetus of masker most animals, its normal for an injury to heal without any inflammation whatsoever, and even in childhood, inflammation is minimal and resolved quickly. Its only as we age and our cells stop functioning properly that inflammation increases and becomes a problem. Red light helps to restore the youthful metabolism that prevents harmful inflammation. Light Therapy kills yeast bacteria. Chart showing the effect of a one time exposure of red 660nm light, at different doses (and control at 0 to candida colonies.3. Perhaps the main reason behind red lights incredible effects on infections red light directly destroys the fungal or bacterial micro-organisms infecting an area.
Studies show a dose dependent effect, so its important to get the right amount of exposure. It seems that higher doses and longer exposure times eradicate more of the candidafig. Low doses seem to just inhibit the growth of yeast. Fungical treatments involving red light usually also involve a photosensitizer chemical, in a combination therapy known as photodynamic therapy. While adding photosensitizer chemicals such as methylene blue does improve the fungicidal effects of red light, red light alone still has a good effect2-3.

Many prescriptions and creams used for treating infections contain anti-inflammatory compounds like hydrocortisone. These can help the body to deal with the stress, but often just mask the underlying problem. Graph summarising the short term effects of low dose 630-780nm red light on inflammation.(5). Red light actually helps the body to deal with the metabolic causes of inflammation5, allowing cells to produce more atp and CO2 through our normal respiration reaction. These products of respiration have an almost identical effect to anti-inflammatory compounds in that they inhibit prostaglandin synthesis (prostaglandins being a main glasvezel mediator of the inflammatory response) and stop the release of various inflammatory cytokines. Changes in cellular metabolism to downregulate inflammation after exposure to red light. Some people think inflammation is seizoen a necessary part of the healing response to infections or injury, but it should be considered a symptom of the body not working correctly.

Illustration of a candida based vaginal thrush infection. Suffering from recurring infections puts the schoonheidsspecialiste skin in a state of constant inflammation, and in this state the body forms scar tissue rather than healing with normal healthy tissue. This disrupts the function of a body part forever, which is a major problem in areas like the genitals. Whatever and wherever on the body you might be prone to these issues, its likely that red light therapy will help significantly, if not cure it permanently. Why exactly is red light so effective against infections? How should you apply the red light to achieve best results? Here are a few ways in which light therapy helps. Red Light Reduces Inflammation, redness, soreness, itchiness and pain are typically linked to infections, as the immune system tries to defend against the aggressive microorganisms. The stress of this interaction on the local tissue contributes towards increased inflammation, which contributes to fungal growth.

Hamblin, department of Dermatology, harvard Medical School, bar 414. Wellman Center for Photomedicine, massachusetts General Hospital 40 Blossom Street, boston ma 02114 p, the use of low levels of visible or near-infrared (NIR) light for reducing pain, inflammation and edema, promoting healing of wounds, deeper tissues and nerves, and preventing tissue damage has been. Originally thought to be a peculiar property of laser light (soft or cold lasers the subject has now broadened to include photobiomodulation and photobiostimulation using non-coherent light. Despite many reports of positive findings from experiments conducted in vitro, in animal models and in randomized controlled clinical trials, lllt remains controversial. This likely is due to two main reasons; firstly, the biochemical mechanisms underlying the positive effects are reviews incompletely understood, and secondly, the complexity of rationally choosing amongst a large number of illumination parameters such as wavelength, fluence, power density, pulse structure and treatment timing has. In particular, a biphasic dose response has been frequently observed where low levels of light have a much better effect than higher levels. This introductory review will cover some of the proposed cellular chromophores responsible for the effect of visible light on mammalian cells, including cytochrome c oxidase (with absorption peaks in the nir and photoactive porphyrins. Mitochondria are thought to be a likely site for the initial effects of light, leading to increased atp production, modulation of reactive oxygen species, and induction of transcription factors.
