Cold Laser Therapy Basics

Over 75 Trillion cells in a human body and they all need energy and electrons to communicate with each other. Laser light delivers the required electrons and energy directly to the cells, enhancing their ability to communicate with each other, absorb oxygen and nutrients and dispose of wastes and toxins. The laser delivers photons to the cells, and mitochondria, which they convert into ATP and use as energy for rebuilding and repairing tissues, tendons, ligaments, nerves and even bones.
Laser therapy is an exciting and relatively new field that can offer people a very safe and effective option to help with speeding up injury repair and reducing pain. provides a unique alternative to patients who are terrified of surgery or drugs, but still seek the powerful healing benefits.
A laser is defined as a device that produces intense radiation in the visible or near visible wavelengths.   Laser light is unique in that it is close to one specific wavelength and propagates in-phase; meaning that all of the electro-magnetic waves oscillate together in an ordered and aligned way.  Together, these conditions make up the term coherency.  When the coherent light is columnated, it can travel vast distances with very  little loss of power or scattering
Laser treatment used for healing is called “low-level laser” or “cold-laser” therapy.  By definition, lasers used for cold-laser therapy range in power from 5 to 500 milliwatts (0.005 to 0.5 Watts).  Lasers less than 5 milliwatts lack the power to induce a bio-stimulatory effect, while lasers greater than 500 milliwatts may cause excessive heating and burn the skin. Lasers used for surgery, however, range from 5 to 50 Watts
Approximately 3,000 clinical studies worldwide have attested to the beneficial and curative effects of therapeutic lasers.

Cold-laser therapy systems are available in several different wavelengths and colors
A lot depends on what you are trying to heal.  Each color reacts differently with the body.
Red lasers (660 nm) can penetrate more deeply, but are still generally used for surface conditions such as healing surface wounds such as bed-sores or diabetic ulcers,burns, acne, and hair restoration.
infrared lasers (905 nm) penetrate much deeper and are used to help heal muscle, ligament, and even bone.
The health benefits of cold laser therapy can be roughly divided into three categories:
1)    Reduce inflammation
2)    Reduce pain
3)    Accelerate tissue repair

 Laser Acupuncture
An increasing body of evidence suggests that laser treatments on specific acupuncture points can stimulate a similar effect as acupuncture needles.The use of laser acupuncture in the ears to help addiction and weight management cases

 Dangers & Risks 
One of the greatest risks of laser therapy is damage to the eyes.  Cold-laser therapy treatments should always be conducted with proper safety glasses worn by both the patient and the practitioner.  Other contraindications for laser treatment include:
• No treatment over suspect tumors or cancer cells
• No treatment over the thyroid

• No treatment over the fontanelle of infants
• No treatment if the patient is using photo-sensitive or immunosuppressant drugs.
These potential risks are a conservative precaution. Special exceptions are already being discovered including the use of laser-therapy to help with macular degeneration

Checklist to laser therapy
Adherence to the laser dosage recommendations from the world association for laser therapy is very important: the eight most important beam parameters  are: wavelength, power, irradiation time, beam area at the skin or culture surface , pulse parameters, anatomical location, number of treatments, and interval between treatments.
The three commonly used dose parameters are time, energy, and energy density.
In addition coherence, application technique(contact, projection, scanning, pressure), beam profile, and spectral width may also be considered important.
Beam power often decreases as the device warms up and as the device ages
