How does laser therapy work?

By | Blog | No Comments

To summarize in one phrase: Laser therapy invigorates the vital system.

In a nutshell:

Light energy enters damaged cells and stimulates  intercellular activity, which reduces pain in that area and accelerates the recovery of the damaged cells. When the cells recover, the healing process is complete.

A more scientific view:
The four widely accepted effects in the scientific literature are:

Biological stimulation / tissue regeneration

Reduce inflammation


Enhance immune function/antibacterial

One important way that laser therapy increases energy is to absorb photons through the mitochondria. These tiny organelles, called cell “power stations,” are found in most plants and animals. Mitochondria are capable of absorbing laser light and then activating a series of reactions that increase and store more cellular energy in the form of adenosine triphosphate (ATP).

By increasing the available energy using this readily accessible form, lasers can greatly stimulate the biological functions of cells, tissues and systems, and even improve the overall life energy of the entire body. “Biological” stimulation = life stimulation!

When energy is available, the body can heal itself.

Laser therapy has been proven to stimulate bone, blood, the insides of blood vessels, cartilage, cochlear hair cells, central and peripheral nerves, and assist with muscle regeneration. In addition, it has been shown that the quality of the healed tissue can be improved. Laser treatment may be the ideal treatment. Not only does it effectively address many medical problems, but also it is widely reported to improve health and well being, as evidenced by many biological markers.

Specific performance:

Cells grow rapidly. Laser therapy accelerates cell propagation and growth.

Wounds heal faster. The laser stimulates the development of fibroblasts of the damaged tissues and the shortening of recovery time is an important consideration factor.

Increases metabolic activity. Because laser therapy induces the body to increase the production of specific enzymes, more oxygen flows to blood cells and there is a more effective immune response.

Reduces the formation of  fibrous tissue. Laser reduces the formation of scar tissue after cuts, scratches, burns or tissue damage after surgery.

Anti-inflammatory effect. Laser reduces swelling caused by joint bruising or inflammation, thereby improving joint mobility.

Increases vascular activity. Laser stimulates the lymph and blood circulation, ensuring the affected tissue receives maximum circulation.

Stimulates neurological functions. Slow recovery of nerve functions in damaged tissues can result in “dead” limbs or numb parts. Laser therapy will speed up the process of nerve cell reconnection, restoring the numb parts back to life. Laser can also increase the amplitude of action potential in muscles to optimize movement.
