Just the Facts, Please
The Science Behind Cold Laser Therapy
Studies have shown that when tissue cultures are irradiated by Cold Lasers, enzymes within cells absorb energy from laser light. Visible (red) light is absorbed within the mitochondria and infrared light is absorbed in the cell membrane. This produces higher ATP levels and boosts DNA production, leading to an increase in cellular health and energy. When applied as treatment, therefore, Cold Lasers have been shown to reduce pain and inflammation as well as stimulate nerve regeneration, muscle relaxation and immune system response.Cold Lasers have no effect on normal tissues, as photons of light are only absorbed and utilized by the cells that need them.
All light is composed of photons. Photons are small packets of light energyin the form of waveswith a defined wavelength and frequency. Photon energy is able to more effectively penetrate the skin and underlying structures, therefore accelerating the healing process.
Light travels at a constant speed and oscillates up and down as it moves forward. However, all light is not the same. It is measured in wavelengths, with each wavelength of light representing a different color of the spectrum.
The number of oscillations per second represents the frequency of each wavelength; shorter waves have a greater frequency than longer waves.
Laser energy is coherent (well-ordered photons), monochromatic (single-wavelength) light energy. When produced as a narrow, bright beam, laser light holds its intensity until it is absorbed by a medium (the body). When applied to the human body, Cold Laser light, tuned to specific wavelengths and frequencies, stimulates metabolic processes at the cellular level.
