What is Cold Laser Therapy?

Cold Laser Therapy is a painless and highly efficient treatment that sends therapeutic wavelengths of light deep into your tissues to facilitate healing at a cellular level. The effects of these specific wavelengths travel further than conventional heat therapies, including ultrasound.


By using light of differing wavelengths, we can provide pain relief and healing to wherever it is needed - superficially, deep, or in between. No perceivable heat is emitted from these lasers in the process - thus the term 'cold laser'.

How Does a Cold Laser Work?

The cold lasers produce impulses of light at a specific wavelength (usually 600 to 980nm) in a way that minimizes reflection and scattering but maximizes absorption of energy at a desired depth.

Some conditions like joint pain require a deep penetration (4-5 inches) that can only be achieved using a powerful laser emitter. Many systems also have other shorter wavelengths and lower power emitters for treating shallow tissue (like the lymphatic system or surface scars).

The goal of laser therapy is to deliver light energy units from red and infrared laser radiation - called photons - to damaged cells. It is the consensus of experts that photons absorbed by the cells through laser therapy stimulate the mitochondria to accelerate production of ATP. This biochemical increase in cell energy is used to rapidly transform live cells from a state of illness to a stable, healthy state.

For shallow treatments, light emitting diodes (or LEDs) with a shorter wavelength (600 to 700nm) are more cost effective for adding photons to the shallower tissue. In addition, red light diodes with a wavelength of 630 to 680 nm may be used to add energy to even shallower levels of tissues.

Cold Laser Therapy is used to treat a wide variety of painful conditions, including Sprains, Strains, Fibromyalgia, Back pain, Neck pain, Bursitis, Carpal Tunnel Syndrome, Soft tissue injuries, Tendonitis, Arthritis, Tennis elbow, Golfer’s elbow and much more.

Benefits of Cold Laser Therapy (CLT)

  • Increased Cell Growth: Laser wavelengths accelerate cellular reproduction and growth.
  • Increased Metabolic Activity: Laser therapy increases production of specific enzymes while increasing oxygen and food particle loads for blood cells. This results in greater production of the basic energy source for our cells, Adenosine Tri-Phosphate (ATP).
  • Faster Wound Healing: Cold laser treatment stimulates fibroblast development, accelerating collagen synthesis in damaged tissue - a key stage in healing.
  • Anti-Inflammatory Action: Laser treatment reduces swelling caused by bruising or inflammation.
  • Increased Vascular Activity: Laser treatment temporarily increases vasodilation,
    increasing blood flow to effected areas.
  • Reduced Fibrous Tissue Formation: Laser wavelengths reduce scar tissue formation that normally occurs
    after tissue damage from cuts, scratches, burns, or surgery.
  • Stimulated Nerve Function: Laser treatment increases the process of nerve cell growth to bring numb areas back to life.
