Light Therapy – Phototherapy



Light Therapy, or Phototherapy, has been used for millennia for healing myriad physical and emotional disorders. Since the Middle Ages, colored stained glass windows served a physiological and spiritual purpose.  But the eye is not the only pathway for light to enter the body and the human energy field. When sunlight streamed through the brilliantly colored panes in Christian churches all over the world, the light frequencies replenished the invisible energy field surrounding the congregants’ physical bodies.  Colored light restored the areas depleted in their subtle energy fields—their spirit. Today, colored light still shines on the faithful, and outside our places of worship, light simply makes us feel good!

One of light’s most encouraging uses for the relief of physical and emotional symptoms can be found in its application for SAD, or Seasonal Affective Disorder. (See Winter Blues listed in the Recommended Reading section below.) During winter months in the northern hemisphere when daylight hours are diminished, full spectrum lighting can provide the visible light frequencies our sluggish bodies and psyches need for nourishment and mood enhancement. Full spectrum light chases the “winter blues.” Delayed sleep-phase disorder (DSPD) or delayed sleep-phase type (DSPT), a circadian rhythm sleep disorder, can benefit from phototherapy.

Light  Therapy very effectively aids the healing of skin disorders such as acne, rosacea, psoriasis and eczema. Dermatitis (e.g. poison ivy) responds remarkably well to indigo or violet light.   An extensive list of photosensitive medications (Go to Articles for a List of foods and photosensitizing agents) provides ample evidence that light can cause biochemical reactions, and does affect the physical body.


Technology uses fiber optic bundles for thousands of applications—from illumination in surgical and dental procedures to telecommunications. Our bodies are made up of cells that have photons, tiny particles that carry varying wavelengths. They are responsible for electromagnetic activity that keep us “charged.”

Light affects our body, mind and spirit so easily and so effectively because skin has trillions of photoreceptors. These receiving packets soak up light signals as a primary nutrient.  Just as sunlight is essential for supplying Vitamin D, a full menu of color is critical for our health and well being. The more colorful our diet of fresh fruits and vegetables, the more brightly we shine!

Phototherapy delivers various frequencies of light waves via fiber optics, lasersLEDsdichroic glass lamps, prisms, or very bright, full-spectrum light.

At Full Spectrum Energy Medicine, we utilize various forms of light — full spectrum, LEDs, laser.  Dr. Dietrich Gümbel’s Derma Color Therapy addresses physical skin disturbances.  In his more complex system,  Cosmo Therapy, described in depth in his book entitled Healing through the Senses, you can access emotional and spiritual issues. In Sensory Healing (Healing through the Senses – Cosmo Therapy), we use one color and its complementary color  in the visible light spectrum ranging from 400 nm (4 x 10-7 m) to 700 nm (7 x 10-7 m) (nanometers).


The Visible Light Spectrum
Color Wavelength (nm)
Red 625 – 740
Orange 590 – 625
Yellow 565 – 590
Green 520 – 565
Cyan 500 – 520
Blue 435 – 500
Violet 380 – 435



JADE and DERMA RAY Anti-Aging Energy Devices combine multiple frequency modalities to jump start repair at the cellular level. These two companion units combine light with microcurrent to non-invasively stimulate cellular repair in situations such as for the elimination of crow’s feet, smile lines, and wrinkles.

Phototherapy—The Light of Consciousness.

Knowing others is wisdom; Knowing the self is enlightenment.”  … Lao Tzu

There is no doubt that phototherapy affects the physical body.  Also known as Photodynamic Therapy and Chromotherapy, it refers to the application of light in various forms.  For focused therapy, light can be shone directly over bare skin at chakra sites; light rays can be applied directly to the skin at acupuncture points, which carry light along the energetic pathways and to the internal organs. Traditional Chinese Medicine did an excellent job of meticulously recording bioenergetic pathways.

Light also operates at the metaphysical level–those layers of our subtle energy field, our auric field. The vibratory rate is much faster than that of our physical bodies, and it is in this intangible realm surrounding our physical body that our thoughts, emotions and premonitions reside. If you ever sensed the presence of someone approaching yet you don’t see anyone in sight, this is an example of your subtle energy body perceiving that person nearby. Suddenly they appear.

This is why mental telepathy is virtually instantaneous: thought lies here outside of time and space. Conversely, memories also become fixed in this virtual space that envelops us. If we continue to act and re-act in our daily lives based on the “programs” installed in the past, it is difficult to overcome emotional roadblocks. Light (and sound) changes all that. Some therapeutic systems utilize flashing (strobic) light to stimulate psychological processes and clear frozen emotional blocks; others use light combined with gentle rocking movement or motion.

Subtle energy responds remarkably well to subtle stimuli.

Carefully chosen healing modalities can help anyone capable and willing to learn how to develop a higher sense of self-awareness.

Light and New Life 

Neonatal jaundice is a yellowing of the skin and other tissues of a newborn infant caused by the accumulation of indirect unconjugated bilirubin in the skin due to an overall increase in the total bilirubin in the blood. Babies whose jaundiced livers otherwise might have jeopardized the infants’ survival quickly begin to thrive under blue light. And farmers routinely use red light to incubate chicken eggs so they can hatch.

Research shows that cancer cells respond to specific wavelengths; as research progresses, we can look forward to using phototherapy for some serious diseases.  The list of light-activated medications, some of which halt cancerous cell growth, is growing every day. Even dentistry routinely uses blue light to “cure” (harden) composite resins for filling cavities. This same blue light, incidentally, has been shown to improve periodontal health.

Other Light Forms

Far infrared light (FIR)  proves extremely helpful in easing muscle pain, and when used in conjunction with saunas can accelerate the detoxification process.

UV, or Ultraviolet light used to sterilize blood is known as Photoluminescence Therapy; it has been used by the medical profession since its discovery in 1922. The following demonstrate the amazing effects it exerts on physiological processes.

  • Inactivation of toxins.
  • Destruction and inhibition of growth of bacteria.
  • Increase in the oxygen combining power of the blood and oxygen transportation to organs.
  • Immunostimulation of cellular and humoral (relating to body fluids) immunity (humoral immunity was a catchall phrase in a time before the complexities of the human immune system were understood)
  • Activation of steroid hormones.
  • Vasodilatation.
  • Activation of white blood cells.
  • Decreased platelet aggregation
  • Stimulation of fibrinolysis (the breakdown of blood clots)
  • Decreased viscosity of blood
  • Stimulation of corticosteroid production
  • Improved microcirculation

Sensory Healing (Healing through the Senses) and Informational Medicine both utilize light as part of their therapeutic repertoire.  Anyone can use light therapy as an adjunct to acupuncture, massage therapy, aesthetic treatments. Light can help artists, musicians and writers with inspiration and creativity.  A recent study suggests that light enhances human physiology when used while practicing yoga.
