The moon shines because its surface reflects light from the sun. And even though it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it.
The moon’s perceived brightness from Earth depends on where the moon is in its orbit around the planet. The moon travels once around Earth every 29.5 days, and during its journey, it’s lit from varying angles by the sun.
This moon’s movement around the Earth — and the simultaneous orbiting of Earth around the sun — account for the moon’s different phases (full moon, quarter moon, etc.). At any given point in the moon’s trajectory around the Earth, only half of its surface is facing the sun, and therefore, only half of the moon is lit up. The other half of the surface faces away from the sun and is in shadow.
Now, I took my first moonlight photograph in 1998, using my father’s old Kodak camera. The results were almost invisible, of course. It was pretty clear that I had no idea what I was doing. But I did know that the feeling of being out under the stars was one that I needed to capture somehow, and I had to find a way to go about doing it.
I left the moonlight photography for a while. Some years later, I read that the brightness of moonlight is extremely variable over a range of many stops and that it was nearly impossible to figure out the brightness of a given scene was going to be ahead of time. The brightness of moonlight under clear skies is as easily predictable as is the brightness of sunlight under similar conditions.
Several things cause moonlight brightness to vary. The most obvious is the moon’s phase. The brightness of moonlight varies by approximately a factor of 10 between the quarter phase and full moon, based on a diffuse reflection and the geometry of the positions of the earth, sun, and moon alone. This is about three and a half stops of light, which is substantial. Another factor is the distance between the earth, moon, and sun, which changes due to the earth and lunar orbits not being perfect circles. The distance from the earth to the sun varies from 0.9833 Astronomical Units at perihelion to 1.0167 Astronomical Units at aphelion. The earth’s distance to the moon varies from 356,400 kilometers at extreme perigee to 407000 kilometers at extreme apogee. The amount of light that falls on a body varies with the inverse square of the distance from the light source, so the combined effect of these distance variations can be quite pronounced. The range of lunar illumination variation is 6.9% for variation in sun distance and 30% for moon distance variation. This amounts to about one-third stop of brightness, which enough to change the mood of a photo when slide films are used.
The third factor in moonlight brightness is the so-called opposition effect. The surface of the moon is covered with small glassy particles that can serve as wonderful retro-reflectors. If you are within a small angle to the line between the sun and moon, the amount of light coming from the moon increases dramatically relative to what you would expect from a diffuse reflection alone. There is quite a range in the magnitude of this effect presented in scientific literature, ranging from a factor of 1.35 to 20! Whatever value you choose to use, the effect is at least one-third stop of light, making it significant to use slide film.
The final parameter that introduces variation into moonlight brightness is atmospheric attenuation, or atmospheric extinction, to use astronomer’s jargon. This accounts for the amount of light absorbed or scattered when light from the moon passes through the earth’s atmosphere. There are two factors involved: the amount of reduction per a given amount of air transited by the light (the “extinction coefficient”) and the amount of air in the light path (“air mass”). Three principal phenomena contribute to the extinction coefficient: molecular absorption, molecular (Rayleigh) scattering, and aerosols’ scattering (particles larger than molecules). See my web page on atmospheric attenuation for more on these individual factors. Overall, an extinction coefficient value is small for dry, clear air but can be huge for moist, dusty air. And the amount of air the light passes through can vary from one “air mass” with the moon directly above you to forty “air masses” when the moon is on the horizon.
So how bright can moonlight be? The brightest moonlight occurs with the moon at perigee and the earth at perihelion, right at the full moon phase. You can never have the moon at its theoretically fullest phase, right opposite the earth from the sun, because whenever the moon goes there, it enters the earth’s shadow, and we get a lunar eclipse! But assuming the eclipse didn’t happen, we could assume the following: a phase angle of zero, apparent air with an “extinction coefficient” of 0.11 magnitudes per air mass, the moon on the zenith so that the moonlight passes through a single “air mass,” the brightness would be 0.0462-foot-candles (LV -2.0), neglecting “the opposition effect.” If we include “the opposition effect,” the brightness could be anywhere from 35% to 20 times brighter (note that 35% is the more accepted value in the scientific literature, which would give an LV of -1.7). I once measured moonlight brightness with a Gossen Luna-Pro incident light meter in mid-winter on the Kelso Dunes at LV=-2.2, so this is a believable result.
There is a rule of thumb, sometimes called the Looney 11 Rule, which says we should treat the moon as being 250,000 times dimmer than the sun. This would have us use a shutter speed 18 stops slower than the 1/(film speed) value that is used in the “Sunny 16 Rule”, which works out to about 44 minutes at f/16 under moonlight conditions with the film having an ISO speed rating of 100 (uncorrected for reciprocity failure!). This is close enough to be useful under full moonlight conditions given an average earth-moon and earth-sun distance, with the moon high in the sky and clear air. Actually, since the sun has an astronomical visual magnitude of -26.74 and the full moon an astronomical visual magnitude of -12.73, the sun is more like 402,000 times brighter than the moon 18.6 stops. Thus using this rule pretty much ensures a minimum of 2/3 stop underexposure — which may actually be fine, since most of the time you want an underexposure to give the impression of the night in the image.
Surprisingly, the moonlight is actually a slightly warmer color than sunlight, as the moon reflectance is higher for longer wavelengths. Yet, on clear nights, with the full moon high in the sky (as little atmospheric influence as possible), the landscape around us appears blueish because of the Purkinje effect: at low illumination levels, our red color sensitivity decreases (as our vision system gradually switches from daylight (cones) to night time vision (using rod cells)).
That’s why the sunlight looks “warm” (more yellow), and the moonlight looks “cold” (bluer — because the insufficient light level changes our color perception), even though the real colors are pretty much the same.
In fact, this is can even become a real problem when taking very long exposure photos at night! They look almost like daylight photos, destroying the intended atmosphere of mystery. Objectively, the photograph is correct, but it is not what we see with our own eyes. Add some blue tint and the night feeling is back.

It was the Taipei Medical University that has developed a study that has given the following conclusion: listening to music at home reduces the severity of symptoms, the intensity of pain and the fatigue experienced by patients with breast cancer .
For the study, published in the “European Journal of Cancer Care,” 60 participants listened to music in five 30-minute sessions per week. After 6, 12 and 24 weeks, music therapy reduced the severity of symptoms, as well as the intensity of pain and fatigue. Furthermore, it instantly reduced physical and mental fatigue.
“The use of music can help the physical and psychological well-being of patients,” explained the study’s lead author, Kuei-Ru Chou. He has also recommended that home music interventions be given to breast cancer patients to reduce their negative thoughts associated with the disease.
From Medina Reeds we send a message of support to all patients who suffer from this disease and we invite everyone, patients and non-patients to apply music therapy on a day-to-day basis for all the wonderful benefits that music brings us.

Researchers at the University of Colorado Anschutz Medical Campus have found that intense light amplifies a specific gene that bolsters blood vessels and offers protection against heart attacks.
"We already knew that intense light can protect against heart attacks, but now we have found the mechanism behind it.”
Study’s senior author Tobias Eckle, MD, PhD, professor of anesthesiology, University of Colorado School of Medicine
The study was published recently in the journal Cell Reports.
The scientists discovered that housing mice under intense light conditions for one week robustly enhances cardioprotection, which resulted in a dramatic reduction of cardiac tissue damage after a heart attack. They also found that humans could potentially benefit from a similar light exposure strategy.
To find out why they developed a strategy to protect the heart using intense light to target and manipulate the function of the PER2 gene, which is expressed in a circadian pattern in the part of the brain that controls circadian rhythms.
By amplifying this gene through light, they found that it protected cardiovascular tissues against low oxygen conditions like myocardial ischemia, caused by reduced oxygen flow to the heart.
They also discovered that the light increased cardiac adenosine, a chemical that plays a role in blood flow regulation.
Mice that were blind, however, enjoyed no cardioprotection indicating a need for visual light perception.
Next, they investigated whether intense light had similar effects on healthy human volunteers. The subjects were exposed to 30 minutes of intense light measured in lumens. In this case, volunteers were exposed to 10,000 LUX, or lumens, on five consecutive days. Researchers also did serial blood draws.
The light therapy increased PER2 levels as it did in mice. Plasma triglycerides, a surrogate for insulin sensitivity and carbohydrate metabolism, significantly decreased. Overall, the therapy improved metabolism.
Eckle has long known that light plays a critical role in cardiovascular health and regulating biological processes. He pointed out that past studies have shown an increase in myocardial infarctions during darker winter months in all U.S. states, including sunnier places like Arizona, Hawaii, and California. The duration of the light isn’t as important as the intensity, he said.
“The most dramatic event in the history of the earth was the arrival of sunlight,” Eckle said. “Sunlight caused a great oxygen event. With sunlight, trillions of algae could now make oxygen, transforming the entire planet.”
Eckle said the study shows, on a molecular level, that intensive light therapy offers a promising strategy in treating or preventing low oxygen conditions like myocardial ischemia.
He said if the therapy is given before high-risk cardiac and non-cardiac surgery, it could offer protection against injury to the heart muscle, which can be fatal.
“Giving patients light therapy for a week before surgery could increase cardioprotection,” he said. “Drugs could also be developed that offer similar protections based on these findings. However, future studies in humans will be necessary to understand the impact of intense light therapy and its potential for cardioprotection.”

Nothing is more important to us on Earth than the Sun. Without the Sun’s heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
We know the Sun through its heat and light, but other, less obvious aspects of the Sun affect Earth and society. Energetic atomic particles and X-rays from solar flares and other disturbances on the Sun often affect radio waves traveling the Earth’s ionosphere, causing interference and even blackouts of long-distance radio communications. Disturbances of the Earth’s magnetic field by solar phenomena sometimes induce huge voltage fluctuations in power lines, threatening to blackout cities. Even such seemingly unrelated activities as the flight of homing pigeons, transatlantic cable traffic, and the control of oil flow in the Alaska pipeline apparently are interfered with by magnetic disturbances caused by events on the Sun. Thus, understanding these changes — and the solar events that cause them — is important for scientific, social, and economic reasons.
We have long recognized the importance of the Sun and watched it closely. Primitive people worshiped the Sun and were afraid when it would disappear during an eclipse. Since the early seventeenth century, scientists have studied it with telescopes, analyzing the light and heat that manage to penetrate our absorbing, turbulent atmosphere. Finally, we have launched solar instruments and ourselves-into space to view the Sun and its awesome eruptions in every aspect.
Once we looked at the Sun by the visible light that reached the ground, it seemed an average, rather stable star. It was not exactly constant, but it seemed to vary in a fairly regular fashion, with a cycle of sunspots that comes and goes in about eleven years. Now the Space Age has given us an entirely different picture of the Sun. We have seen the Sun in other forms of light-ultra violet, X-rays, and gamma rays that never reach the ground from space. This radiation turns out to be far more responsive to flare eruptions and other so-called solar activity.
We now see the Sun as a place of violent disturbances, with wild and sudden movements above and below its visible surface. Besides, solar activity's influence seems to extend to much greater distances than we had believed possible. New studies of long series of historical records reveal that the Sun has varied in the past in strange and unexplained ways. Scientists wonder how such variations might affect the future climate on Earth.
We have obtained a clearer picture of the scope of the Sun’s effects. Its magnetic field stretches through interplanetary space to the outer limits of the solar system. Steady streams and intense storms of atomic particles blow outward from the Sun, often encountering our Earth's atmospheres and the other planets. The spectacular photos of the Earth from space show only part of the picture. Instruments carried on satellites reveal a wide variety of invisible phenomena — lines of magnetic force, atomic particles, electric currents, and a huge geocorona of hydrogen atoms — surrounding the Earth. Each is as complex and changing as the visible face of the globe. The Earth’s magnetic field extends tens of thousands of miles into space, and many different streams of electrons and protons circulate within it. Huge electric currents flow around the Earth, affecting their high-altitude surroundings as well as our environment at ground level.
Space observations have greatly expanded our ability to look at the Sun, interplanetary space, and the Earth's immediate surroundings. We can now “see” many phenomena that are completely undetectable from the Earth’s surface, and we now have a much better, more complete, and more coherent picture of how events in one part of our solar system relate to activity in another.
We sometimes forget that there is one star that is easily visible in the day time: our Sun. The Sun is the only star close enough to be studied in detail, but we are confident that all the processes in the Sun must also occur in billions of distant stars throughout the universe. To understand the nature and behavior of other stars, we must first understand our own. At the same time, observations of other kinds of stars help put the Sun in perspective.
The Sun is a relatively typical star among the approximately 100 billion stars in our Milky Way galaxy. The masses of most other stars that we see range from approximately one-tenth of the mass of the Sun to about 30 solar masses. The surface temperatures of most stars range from about 2000° C to 40,000° C. Although the Sun is somewhat on the cool side at about 6000° C, hot stars are rare, and most normal stars are cooler than the Sun. Compared to some of the explosive stars — novae, and supernovae — which sometimes appear in the sky, the Sun is stable and ordinary.
This long-term stability of our Sun probably was crucial for the development of life on Earth. Biologists believe that a relatively stable average temperature had to prevail on Earth during the past 3 billion years for life to evolve to its present state. The relative stability of the Sun is also important to astronomers trying to understand the basic nature of it and other stars. Violent activity in the Sun could mask the more subtle and long-enduring processes, which are the basic energy transport mechanisms of our star. Fortunately, they are not hidden, and we have been able to map the trend in solar properties with height above the visible surface.
Above the minimum temperature region in the photosphere, we have measured how the gas gets hotter as it thins out with height. The chromosphere and corona, each hotter than the layer below, are warmed by the transfer of energy from below through processes that are still not well understood.
Until space observations became possible, we knew nothing about coronae in any other stars and had only marginal information about stellar chromospheres' properties. Now, space observations have shown us that a large fraction of the stars in the sky have chromospheres and coronae.
On several dozen stars, we have even detected activity that may be connected with sunspot (or “starspot”) cycles like those of our own Sun. X-ray telescopes carried on satellites have recorded flares in other stars that are far more powerful than the already impressive flares of the Sun. By observing the strength and frequency of these events on stars with masses, ages, and rotation rates which differ from those of the Sun, we search for answers to such basic questions as: “How does the sunspot cycle period depend on the star’s rotation rate?” or “What is the relation between the temperature of a star’s corona and the strength of its magnetic field?” By deciphering the general pattern of stellar properties, we can better understand what makes things happen on the Sun.
The Sun presents us with a bewildering variety of surface features, atmospheric structures, and active phenomena. Sunspots come and go. The entire Sun shakes and oscillates in several different ways at the same time. Great eruptions called prominences hang high above the Sun’s surface for weeks, suspended by magnetic force, and sometimes shoot abruptly into space from the corona. The explosions called solar flares emit vast amounts of radiation and atomic particles in short periods of time, often with little or no warning.
Space observations have discovered many new aspects of solar events hidden from ground-based observatories—the Sunshine's hottest spots primarily in ultraviolet and X-rays, rather than in visible light. Thus, only from space can we map high-temperature solar flares' true structure and determine their physical conditions. Space observatories have shown us the higher, hotter layers of the Sun’s atmosphere that normally are invisible from the ground. Instruments on satellites revealed that in flares and other violent disturbances, the Sun acts like an atomic accelerator, driving electrons and protons to velocities approaching the speed of light. At such high speeds, the particles emit the high-energy X-rays and gamma rays measured by our satellites. Sometimes they even induce nuclear reactions on the surface of the Sun.
Two aspects of our improved knowledge of the Sun deserve special attention. One is the role of magnetic fields in determining virtually all aspects of the Sun’s upper atmosphere's structure and behavior. The other is discovering the solar wind, a stream of atomic particles that constantly evaporate from the Sun’s atmosphere and are accelerated to speeds of hundreds of kilometers per second, escaping into space in all directions.
For any solar particle to reach the Earth, it must first pass through the Earth’s magnetic field. Before the solar wind was discovered, the Earth’s field was thought to be symmetrical, resembling a huge bar magnet, fading off indefinitely into space. However, we now know that the solar wind shapes the Earth’s magnetic field's outer regions and is sharply bounded. Outside the boundary, space is dominated by the solar wind and the interplanetary magnetic field. Inside the boundary is the region or magnetosphere dominated by the Earth’s magnetic field. The measurements from many space missions have been combined to reveal that the solar wind blows out the Earth’s magnetosphere into a teardrop shape. The head of the drop extends only about 10 Earth radii, or about 65,000 kilometers (40,000 miles) “upwind” toward the Sun. The tail of the drop stretches away in the direction opposite the Sun, actually reaching beyond the Moon’s orbit. This long magnetotail extends more than 600,000 kilometers (370,000 miles) from the Earth.
At the boundary of the magnetosphere, there is a constant struggle between the Earth's magnetic field and the forces of the Sun. Buffeted by fluctuations in the solar wind velocity and density, the magnetosphere’s size and shape are continuously changing. When the solar wind strikes the magnetosphere, shock waveforms are analogous to the sonic boom preceding a supersonic airplane. Inside the boundary with the solar wind, the magnetosphere remains an active region. It contains two belts of very energetic charged atomic particles trapped in the Earth’s magnetic field hundreds of miles above the atmosphere. These belts were discovered by Professor James Van Allen of the University of Iowa and his colleagues in 1958, using simple radiation detectors carried by Explorer 1, the first U.S. satellite.
The structure of the Earth’s magnetosphere also controls aurorae's behavior, seen in our night skies. Pre-Space Age textbooks stated that aurorae are produced by photons emitted from the Sun and reach the Earth’s upper atmosphere through gaps in the Earth’s magnetic field at the north and south magnetic poles. According to the theory, these protons strike oxygen atoms in the atmosphere, and the collisions cause the glow, which we call the Northern Lights.
This view has changed in the Space Age. The data collected by many spacecraft showed that the situation is more complicated. Particles from both the solar wind and from the Earth’s atmosphere apparently are stored in the magnetotail. From there, they periodically are violently ejected into the northern and southern polar regions of the atmosphere along the Earth’s magnetic field. They are accelerated to high speeds by a process not yet fully explained. The magnetotail is, in effect, a reservoir of particles that is periodically refilled. When the Sun is active during maximum sunspot years, this process is especially intense and frequent, and the aurorae are brighter and move closer to the equator.
Color Light therapy is based on the idea of restoring balance by applying color to the body. Its history is rooted as far back as the Mayan culture.
In India, Ayurveda, an ancient form of medicine practiced for thousands of years, is based on the idea that every individual contains five elements of the universe that are present in specific proportions unique to each individual, including their personality type and constitution. When these elements are out of balance, Ayurveda works with the energies inherent in the colors of the spectrum to restore this balance.
In ancient Egypt the art of healing with color was founded in the Hermetic tradition, the Ancient Egyptians and Greeks used colored minerals, stones, crystals, salves, and dyes as remedies, and painted treatment sanctuaries in various shades of color.
In China, traditional Chinese medicine incorporates color to be associated with each organ and elemental system. This healing method looks at the idea that every individual is a balance. The first color wheel was invented by Sir Isaac Newton. He split white sunlight into red, orange, yellow, green, cyan, and blue. He then joined the two ends of the color spectrum together to show the natural progression of colors.
Light Therapy has been valued throughout history as a remarkable source of healing. Today, the therapeutic applications of light and color are being investigated in major hospitals and research centers worldwide. Results indicate that full-spectrum, ultraviolet, colored, and laser light can have therapeutic value for a range of conditions from chronic pain and depression to immune disorders.
Light Therapy has been reported, as part of a healthy lifestyle, to temporarily reduce swelling, relieve pain, decrease inflammation, accelerate open wound healing and greatly reduce overall recovery after medical/surgical procedures. Patients have demonstrated an increased range of motion, decreased muscle tension and spasm, and improved circulation.
Rejuvenating LED light therapy can be used for temporary pain management such as joint and back pain, sore or torn muscles, sprains, arthritis, post-surgical scars, burns, wounds, and more. When used with infrared technology, light therapy (phototherapy) is one of the most effective and non-invasive ways to improve overall wellness.
Light therapy is also used to temporarily relieve Seasonal Affective Disorder (SAD). SAD affects individuals when the lack of sunlight results in seasonal depression. Phototherapy helps with SAD by resetting the internal biological clock (Circadian rhythms), helping individuals sleep better, and regulate their mood. Even companies, such as GE and Philips, have created phototherapeutic products to improve and regulate mood.
Light therapy is also a growing treatment for anti-aging. Many individuals have seen a temporary reduction in the appearance of fine lines, wrinkles, crow’s feet, and age spots.
Light therapy is “effective at improving the appearance of the face, neck, and chest by reducing the signs of aging, wrinkles and age spots”, says Web M.D. Combined with infrared therapy, LED phototherapy can be a great way to revitalize skin.
Color is light split into different wavelengths vibrating at different speeds and at different frequencies. Objects that ABSORB all wavelengths and DO NOT reflect are black in nature. Objects that REFLECT all wavelengths and DO reflect are white in nature. Between black and white lies COLOR. Colors are wavelengths of energy that, to us, appear as color because of the potential and capabilities of the object to either absorb or reflect the energy.
In the early 1990s, RLT was used by scientists to help grow plants in space. The scientists found that the intense light from red light-emitting diodes (LEDs) helped promote the growth and photosynthesis of plant cells.
The red light was then studied for its potential application in medicine, more specifically to find out if RLT could increase energy inside human cells. The researchers hoped that RLT could be an effective way to treat the muscle atrophy, slow wound healing, and bone density issues caused by weightlessness during space travel.
You may have heard of red light therapy (RLT) by its other names, which include:
Red is called “The Great Healer”. So far is the most popular light therapy. To wind down before bed, use red light. “The color signals that it’s night, which may encourage the body to produce melatonin,” says Michael Breus, Ph.D., an advisory board member for SleepScore Labs.
Red light can also improve your workout. Just one to five minutes of exposure to red and infrared light right before exercise boosted strength and prevented soreness, says Ernesto Leal-Junior, Ph.D., the head of the Laboratory of Phototherapy in Sports and Exercise at Nove de Julho University in Brazil. “Certain wavelengths of red and infrared light-660 to 905 nanometers-reach skeletal muscle tissue, stimulating the mitochondria to produce more ATP, a substance that cells use as fuel,” he says.
Green is the universal healing color. Originally, the color of love. Green is midway in the color spectrum; therefore, it contains both a physical nature and a spiritual nature, in equal balance and in equal harmony.
Gazing at green light can reduce chronic pain (caused by fibromyalgia or migraines, for example) by up to 60 percent, according to a study in the journal Pain, and animal studies have shown that the beneficial effects can last up to nine days. “Looking at green light seems to lead to an increase in the body’s production of enkephalins, pain-killing opioid-like chemicals. And it reduces inflammation, which plays a role in many chronic pain conditions,” says researcher Mohab Ibrahim, M.D., Ph.D.
More studies are needed before doctors can make recommendations on how and how often to use green light to treat migraines and other pain, and Dr. Ibrahim says you should see a physician before trying to treat yourself at home. But at this point research indicates that exposing yourself to an hour or two every night-either by using a green light bulb in a lamp or by wearing glasses fitted with tinted optical filters-may decrease migraines and other types of chronic pain
Helps to treat and prevent hyper-pigmentation by inhibiting the production of excess melanin which then prevents it from traveling to the surface. It will help break up the melanin clusters that are already on the surface.
Yellow helps awaken mental inspiration arousing a higher mentality. Thus, it is an excellent color for nervous or nerve-related conditions or ailments; fueling the solar plexus. Yellow has a very enriching effect upon the intellect. Yellow can be used for conditions of the stomach, liver, and intestines. It can help the pores of the skin by repairing scarred tissue. These rays have an alkalizing effect which strengthens the nerves. Awakening, inspiring, and vitally stimulating the higher mind promoting self-control. Typical diseases treated by yellow are constipation, gas, liver troubles, diabetes, eczema, and nervous exhaustion. Providing clarity of thought, increasing awareness, stimulating interest, and curiosity yellow energy is related to the ability to perceive or understand.
The yellow is used for treating redness, flushing, irritation, and Rosacea. It may also reduce the appearance of the tiny blood vessels on the nose and face.
Blue light therapy technology is an additional option for the treatment of acne. Research has shown in-office and at-home systems produce positive results.
“Blue light therapy effectively helps alleviate this common skin condition affecting 50 million Americans and 94 percent of all females, according to Judith Hellman, MD, a board-certified dermatologist, in practice in New York City. Dr. Hellman, who practices medical dermatology and specializes in dermatological surgery, laser surgery, and anti-aging skin treatments, explains how the blue light treatment system works for acne, its uses, and her clinical experience with the technology.
It is used as a gentle acne treatment to control oil production in the skin as well as reduce inflammation. It also promotes the synthesis of protein and collagen.
Orange Light
Orange has a freeing action upon the mind, relieving repression. Because orange is a blend of red and yellow, it combines physical energy with mental wisdom, inducing a transformation between lower physical reaction and higher mental response. Thus, it is often referred to as “The Wisdom Ray.” Orange is warm, cheering, and non-constricting.
Through orange, we are able to heal the physical body (red) and, at the same time, induce within the mind (yellow) greater understanding. Orange helps assimilate new ideas. Orange is the best emotional stimulant, helping to remove inhibitions paving independent social behavior. Bring joy to your workday and strengthen your appetite for life. Orange aids in repairing inflammation of the kidneys, gallstones, menstrual cramps, epilepsy, wet cough, and all sinus conditions.
Purple Light
Violet is the last color we can see before light passes on to ultra-violet. Violet purifies our thoughts and feelings giving us inspiration in all undertakings. The violet energy connects us to our spiritual self bringing guidance, wisdom, and inner strength and enhances artistic talent and creativity. Leonardo da Vinci proclaimed that you can increase the power of meditation ten-fold by meditating under the gentle rays of Violet, as found in church windows.
Light therapy uses colors for their proposed wellness abilities in treating emotional and physical disturbances. Light therapy is based on the premise that different colors evoke different responses in people. For example, some colors are considered to be stimulating, whereas others may be soothing. Color therapy has been suggested for many uses, based on tradition or on scientific theories. Consult with a health care provider before using color therapy for any use.
Infrared Light
Infrared light penetrates to the inner layers of the skin at about 2 to 7 centimeters deep. Hence, it reaches the muscles, nerves, and even the bones. Many studies have shown that a frequency of infrared light, with wavelengths from 700 to 1,000 nanometers, is best used for healing inflammatory conditions.
The use of electricity for healing purposes began in 2,750 BC when people used electric eels to give electric shocks. Electricity and magnetism were used in people with just little success. However, in 1975, transcutaneous electrical stimulation (TENS) was developed to treat chronic pain. It was not until recently that infrared therapy was developed to improve wound healing, reduce the pain caused by arthritis, boost endorphin levels, and bioactivate neuromodulators.
Infrared therapy technology allows people to harness the benefits of the sun, without being exposed to harmful ultraviolet rays. Also, infrared therapy is safe and effective, without adverse side effects. As a matter of fact, infrared light is safe and is used even for infants in neonatal intensive care.
Infrared light is absorbed by the photoreceptors in cells. Once absorbed, the light energy kickstarts a series of metabolic events, triggering several natural processes of the body on a cellular level.

As humans, we are made of energy and fueled by light. While nutrition and exercise play a role in our well-being and health, light plays a crucial role in us functioning optimally. New and groundbreaking research is unearthing a new understanding of how our cells function and the evidence points to the power of light.
Through technological advancements in science, it’s discovered that our bodies operate similar to a battery. Wavelengths of light give us power, while our overall health determines our ability to receive and maintain the energy from light. And this is where light therapy comes into the equation.
Science has proven that our bodies interact with specific wavelengths that benefit our bodies in various ways.
Red light therapy devices, such as light therapy masks, shine red and near-infrared light onto the skin, stimulating the production of adenosine triphosphate (ATP) within the mitochondria. By stimulating ATP, damaged cells heal, and new cells are produced faster than normal. But we’ll talk more about that in-depth a little later.
Red light therapy comprises both red light and infrared wavelengths, penetrating through the skin’s layers, right into the cells. Red light wavelengths boost collagen and elastin and improve cell communication. It penetrates superficially and helps aid various skin conditions.
Near-infrared wavelengths stimulate healing, increase mitochondrial function, and improve blood flow and tissue oxygenation. Near-infrared wavelengths penetrate deeply into the body.
At the core of your body’s healing capabilities are the mitochondria. The mitochondria play a vital role in your internal organs and tissue, including the liver, skin, heart, and muscles. It’s in charge of the body’s energy supply via ATP (adenosine triphosphate).
With both working together, they provide energy to our body and maintain the cell cycle and growth. This is why you’ll often hear the mitochondria referred to as the “powerhouse of the cell.”
Here's how the mitochondria is affected by red light:
Interestingly, our body weight is made of 70% water, with 99% of our bodies' molecules also made of water, making it a powerful component in red light therapy treatment.
Research by Prof Gerald Pollock of the University of Washington proved that water adjacent to a cell is structured water, also known as EZ water. This specific water forms a separation of charge, functioning in the body as positive and negative poles - similar to a battery.
While we’ve been talking about red light therapy, what does it actually mean? Typically, “red light therapy” refers to natural light treatments which deliver red and near-infrared wavelengths as natural sunlight using LEDs or cold lasers.
While you may think red light therapy includes all colors of light, it doesn’t. The term doesn’t include blue or white light, and it isn’t equivalent to full-spectrum light. Red light therapy doesn’t rely on heat, differentiating it from other light-based treatments such as infrared saunas and heat therapy.
Red light therapy is also known as RLT, photobiomodulation (PBM), phototherapy, LED therapy, LED light therapy, infrared therapy, low-level laser therapy, or low-level light therapy (LLLT).
As stated before, red light therapy works to heal the entire body and functions on multiple levels.
Red light therapy affects the body in multiple ways, including bodily systems:
Fascia
Fascia is the thin casing of connective tissue that surrounds virtually every organ, muscle, nerve fiber, blood vessel, and bone in place. While it performs as an internal structure for your body, the fascia also contains nerves, making it almost as sensitive as skin.
The fascia may look like a layer of tissue; however, it’s made up of interwoven layers of collagen and elastin fibers. The fascia is overlooked, yet over recent years, it has been the key to understanding how changes in one area of our body affect others. Red light therapy works to improve communication within the fascia network.
Gut-Brain Axis
The gut-brain axis connects the emotional and cognitive centers of the brain with peripheral intestinal functions. Recent research discovered the importance of gut microbiota concerning these interactions.
Red light therapy can positively influence mood and neuropsychological issues by the following:
Immune System
Red and near-infrared light penetrate through the skin into the cells, which results in low-dose metabolic stress that strengthens the cells’ anti-inflammatory and natural defense systems. In turn, the body becomes resilient to infections.
Safe and low exposure to red light therapy improves the body’s response to external viruses and bacteria. Red light therapy can influence the immune response in the following ways:
Circulatory System
Red light therapy is scientifically proven to increase the micro-circulation of blood and support the circulatory system as a whole by stimulating the development of new capillaries which carry oxygen throughout the body.
Proper oxygen supply and flow are essential for the proliferation of cells, protein synthesis, tissue restoration, inflammatory response, and angiogenesis. In addition, circulation is also responsible for waste elimination, specifically degenerated cells.
Nervous System
The nervous system includes the brain, spinal cord, neurons, and neural support cells, which is your body’s command center. It controls your movements, automatic responses, and other body systems such as digestion and breathing.
Red light therapy affects the nervous system in the following ways:
For all forms of nerve damage, red light therapy offers non-pharmaceutical treatment options.
Stem Cells
Red light therapy shows impressive results regarding stem cell growth, maximizing the potential of stem cell implantation for various medical needs. Therefore, red light therapy may show positive results after surgery to stimulate stem cells which repair tissues and organs.
In studies, red light therapy has proven to stimulate mesenchymal stem cells in bone marrow, enhancing their ability to reach the brain. This research shows the possibilities of using red light therapy to heal degenerative conditions, including Alzheimer’s, Parkinson’s disease, and dementia.
It’s clear red light therapy provides multilevel treatment to the body, becoming a popular natural and holistic option for both professionals and consumers, but where did it come from?
Light therapy technology isn’t new; it’s been around for decades as NASA experimented with red light therapy during the 1980s and 1990s. Over the past 10-20 years, red light therapy reached a breakthrough in LED lighting technology, allowing the production of safe and affordable clinical and at-home devices.
In 2016, Kaiyan Medical became the first leading manufacturer of red light therapy of affordable FDA-approved and MDASAP-approved light therapy devices.
We mentioned red light therapy being a holistic treatment option, but what does that mean. Holistic medicine is a full-body approach to healthcare. By focusing on the body, mind, and soul, the body receives the full support and care it needs to function optimally.
Principles of Holistic Medicine
Holistic medicine is based on the following principles:
The purpose of treatment is to identify the underlying cause of the disease, rather than treating only the symptoms.
While there are endless benefits the body receives from red light therapy, here are the six main benefits.
Photobiomodulation, in other words, red light therapy, has proven effective against carpal tunnel syndrome, mucositis, neck pain, menstrual cramps, temporomandibular joint pain, and neuropathic pain from amputation. It also significantly reduces the pain of hypersensitivity while improving sensorimotor function.
These improvements come after anti-inflammatory cells populate the injured area, providing long-lasting pain relief. In addition, it’s also been shown to provide effective relief by affecting the following:
Red light therapy has proven to be highly effective in rapidly treating wounds from burns, scars, bedsores, ulcers, surgery incisions, and diabetic neuropathy.
NASA strongly supports this claim as this technology was used in treating wounds. Red and near-infrared light proves effective in all four phases of the wound-healing process:
These processes are regulated by various factors connected via nitric oxide (NO) signaling release, adjusted by light energy.
An issue the body encounters when trying to heal a wound is low oxygen flow, and red light increases the flow of oxygen, speeding up the natural healing process. By reducing inflammation and increasing oxygenation of the wounded area, blood vessels can form, rapidly repairing the area, lessening pain and scarring.
By reducing pain, red light therapy eliminates the reliant on pharmaceutical painkillers during the healing process.
The human body receives energy on the cellular level, maintaining communication between organs and ensuring disease resistance.
A strong immune system works to protect the body from harmful bacteria and viruses at all times. With red light therapy, the body receives a boost of support as it releases nitric oxide and melatonin, two components involved in DNA repair and antimicrobial.
This process is called hormesis. Red and near-infrared wavelengths penetrate through the skin into the cells, causing mild metabolic stress, which stimulates cells to activate their anti-inflammatory and antioxidant response.
With the support of red light therapy, the body is better prepared to fight infections. Numerous studies have proven red light therapy to have the following effects on the immune system:
Inflammation in the body can be acute and topical (short-term, resulting from sprains, infections, and accidents) or chronic and general (long-term, caused by ongoing conditions).
Acute inflammation is a healthy bodily response; however, chronic and general inflammation can negatively impact long-term health.
As of today, the current treatment for inflammation is NSAID or steroid drugs, both having a detrimental effect on the healing process and long-term health. Red light therapy stimulates the body to activate its natural healing mechanism, reducing the health risks of long-term drug use.
Red light therapy decreases the number of inflammatory cells, increases fibroblast proliferation (cells that synthesize collagen and other matrix macromolecules), stimulates angiogenesis (creation of new blood vessels), and activates the body’s anti-inflammatory, antioxidant response.
The following conditions are connected with chronic and acute inflammation, all proving promising results with red light therapy treatment:
Red light therapy is extremely popular in competitive sports and performance. It offers natural and non-pharmaceutical treatment, which applies to many areas of the body.
Aside from the overwhelming benefits on overall health, red light therapy encourages muscles growth and repair by stimulating the production of ATP, which aids in faster recovery and better performance.
Red light therapy used before training prepares and strengthens the body while aiding muscle recovery after training.
Here are the scientifically documented effects of red light therapy:
Seasonal affective disorder (SAD) is a form of depressions, impacting 5% of Americans, specifically during the winter when there’s less natural sunlight. SAD is also known as seasonal depression or winter blues.
Many people treat SAD symptoms via bright white light treatment, mimicking the sun’s light daily. However, researchers recommend natural light treatment, like red light therapy, to help with light deficiency. Over recent years, physicians recommend red light therapy alongside psychotherapy and medication.
While many people are using red light therapy devices for at-home treatment, red light therapy systems are found in many clinical and professional settings:
Skincare Professionals: Red light therapy is a popular skincare treatment among Hollywood celebrities, including Kourtney Kardashian, Julia Roberts, and Emma Stone. Leading skincare professionals like dermatologists and aestheticians use red light therapy to help promote collagen production, reduce wrinkles, and treat skin conditions.
Health Practitioners: Health practitioners from all specialties are incorporating red light therapy into their practice. Dentists use it to reduce inflammation, physicians for mental health conditions, and oncologists for cancer side effects.
Natural Health Experts: Leading voices in the health and wellness industry such as Dr. Sarah Ballantyne, Ben Greenfield, and Dave Asprey strongly support the use of red light therapy. Paleo and Keto health experts like Robb Wolf, Mark Sisson, Luke Story, and Dr. Anthony Gustin also support red light therapy.
Sports Medicine Pros: The National Sports Association of Sports Medicine (NASM) adopted red light therapy to treat sports injuries. Top trainers and doctors, including Dr. Troy Van Biezen and Dr. Ara Suppiah, use red light therapy to heal their athletes.
Elite Pro Athletes: Professional athletes worldwide, including NFL stars like Patrick Peterson, UFC champion Anthony Pettis, and gold medal gymnast Sanne Weavers use red light therapy to enhance performance and quicken recovery.
Fitness & Training: World-renown fitness trainers, including Lacey Stone and Jorge Cruise, use red light therapy to enhance athletic performance and muscle recovery.
Supportive Cancer Care: The Multinational Association of Supportive Care in Cancer (MASCC) recommends the treatment of red light therapy for oral mucositis (OM), a common symptom of cancer treatment.
