Light Therapy

2. Motivation
 You know how much better you feel on a bright
sunny day?
 You are experiencing light therapy as nature
intended it.
 Light therapy is not new, but has been used in the
medical practice of just about all cultures since the
beginning or recorded history.
 Sunlight is composed of a variety of energies that are
transmitted to Earth in the form of electromagnetic
waves.

3. Light therapy
 Light therapy—or phototherapy, classically referred
to as heliotherapy.
 Finsen is known as the inventor of phototherapy or
artificial light therapy, and for this he won the Nobel
Prize for Medicine in 1903, being the third person to win
it in this category
 Light therapy is the use of natural daylight,
artificial daylight (full spectrum light), or any
single color to promote an overall sense of well
being, correct the imbalances caused by a lack of
natural light, or stimulate a specific healing
response in the body.

4. Light Therapy Treatment Techniques
 There two general ways that light therapy treatments
are administered:
1) Light taken in through your eyes.
2) Light shone on your skin.

5. Light Through Your Eyes
 Light travels through your eyes directly into the
hypothalamus of the brain, thereafter having an
effect on every system of your body. Forms of light
therapy that employ this fact include:
 1) Bright Light Therapy
 2) Dawn Simulators
 3) Color Tinted Glasses
 4) Syntonics

6. Bright Light Therapy
 Bright light therapy treatments use a “light box” that
uses a white or blue light to provide intense exposure
under controlled conditions.
 Benefits are quite widespread, ranging from the
prevention of seasonal affective disorder (SAD) and
minimizing its symptoms, to improving circadian
rhythms in order
to promote better sleep.

7. Dawn Simulators
 Dawn simulators are light therapy that are usually
used to help in the treatment of seasonal affective
disorder (SAD).
 they are also used by some individuals who wish to
wake up naturally and build an “alarm clock” into
their bodies.
 A standard dawn simulator treatment involves
timing the devices to start to add light to a bedroom
so that it will gradually increase over a period of
thirty minutes to two hours before it is time to rise.

8. Color Tinted Glasses
 Color can promote many different types of reactions
in the body, from better overall health and wellness
to an improved mood. Color tinted glasses allow you
to control the type of impact that these benefits will
have on your mental and physical wellbeing. The
eyewear must be worn for 10 to 30 minutes each day
either outdoors or indoors. Each of the nine colors
has a different impact on your health and mood:

9. Color tinted glasses
 Magenta – soothing, relaxing, gentle, and emotional balance.
 Red – courage, sense of power, pioneering spirit, overcoming
negative influences, strength, and vitality.
 Orange – resourcefulness, cheerfulness, social confidence, and
enjoyable relationships.
 Yellow – mental clarity, optimism, and focus.
 Green – self control, calm, hope, peace, balance, and the reduction
of stress.
 Aqua – sensitivity, feeling soothed, confident, and relaxed.
 Blue – calm, mental relaxation, peace, clear communication,
creativity, and vitality.
 Indigo – serenity, understanding, clear perception, imagination,
and deep sleep.
 Violet – inspiration, beauty, creativity, lowered irritation, and
soothed nerves.

10. Syntonics
 Syntonics, also known as optometric phototherapy, is a
gentle and safe ocular therapy where visible light
wavelengths are selected to be shone through the eyes.
 It has had clinical applications for more than seventy
years as an alternative treatment to lazy eye, eye turns,
depth perception and limited peripheral vision.
 According to the National Institutes of Health, half of the
body’s blood volume passes through the eyes every 40
minutes. The NIH also states that the hemoglobin within
the blood has a biochemical light mechanism.

11. Light on Your Skin
 The skin is the largest organ of your body and has
been designed to absorb light in many different
ways. Sunlight on your skin is the only natural
way of Vitamin D production. The result of the
sunscare has been epidemic Vitamin D
deficiency. Colored light shone on the skin is the
basis for a wide variety of light and color therapy
techniques including:

12. Photofacial & Photorejuvination
 Photofacial, or photorejuvination is a form of skin
treatment that uses light to treat various forms of
cosmetic skin conditions such as wrinkles and age
spots, acne and can help to reverse the effects of hair
loss.

13. Intense Pulsed Light (IPL)
 Intense Pulsed Light (IPL) therapy uses frequencies
of light in order to help to reduce the appearance of
various forms of skin discoloration issues (such as
sun spots), freckles, birthmarks, fine lines, spider
veins, varicose veins, broken capillaries.
 This type of therapy is performed by a trained
dermatologist
 It can take up to six months for the benefits of that
treatment to be visible.

14. Conventional Medical Use
 Blue light therapy and red light therapy have a number of
highly beneficial uses in conventional medicine.
 jaundice, which is treated in many hospitals in the
United States, Canada, and around the world using blue
light.
 MRSA bacteria that is resistant to antibiotics can be
effectively killed using blue light therapy without
negative side effects.
 Acne bacteria can be painlessly eliminated with blue and
red light therapy, which can also be used to maintain the
complexion once the pimples have cleared up.

15. Photodynamic Therapy (PDT)
 Photodynamic therapy (PDT) is a type of treatment that
uses a drug that is sensitive to light and that can be
activated within the body through the use of lasers in
order to kill cells. This is most often used for the
eradication of cancer cells.
 The process involves the use of a special drug that is
typically administered by injection. This medication is
absorbed into the cancerous cells. One to three days
later, a doctor targets the area with a laser, causing the
cells to react with oxygen and die. In the case of surface
tumors, as is the case in skin cancer, the drug may be
applied topically and a light emitting diode (LED) may be
used by the doctor instead of a laser.

16. Meridian Points (Colorpuncture)
 alternative healing technique that finds its origins
with a German naturopath and scientist named Peter
Mandel.
 The process involves shining specific colors of light
onto meridian or acupuncture points on the skin.
This can help to use the benefits of the color’s
energies to stimulate healing impulses in the points
of the body which can be assisted from those
energies.

17. Chakra Zones
 The chakras are spirals of energy that circulate within
our bodies and that move in unison with one another.
 Violet – the crown chakra
 Indigo – the brow chakra
 Blue – the throat chakra
 Green – the heart chakra
 Yellow – the solar plexus chakra
 Orange – the sacral chakra
 Red – the base (root) chakra

18. Conclusion
 Like sunlight to a plant, we are dependent upon light
for health.
 light therapy that we use to balance your
electromagnetic field strengthening your immune
system, balancing your chakra system and balancing
your mind and body through acupuncture points.
