How Does Laser Light Heal?

Healing with the use of light is not new. Light therapy was reported to be effective for many conditions by Hippocrates. With the development of the laser and its special properties, using light as a treatment has gained more popularity. This is because we can now use specific wavelengths of light and give accurately measured doses of energy directly to the appropriate treatment site, which was not possible with other light sources.

Low level lasers supply energy to the body in the form of non-thermal photons of light. Light is transmitted through the skin's layers (the dermis, epidermis and the subcutaneous tissue or tissue fat under the skin) at all wavelengths in the visible range. However, light waves in the near infrared ranges penetrate the deepest of all light waves in the visible spectrum. When low level laser light waves penetrate deeply into the skin, they optimize the immune responses in our blood. This has both anti-inflammatory and immunostimulate effects. It is a scientific fact that light transmitted to the blood in this way has positive effects throughout the whole body, supplying vital oxygen and energy to every cell.

When the low-level laser hits the tissues, it stimulates the mitochondria to produce more ATP (adenosine triphosphate) to power health restoration while maintaining biology. Low-level laser light promotes vasodilation that increases nutrient flow to maintain tissue and organ health, while increasing circulation. Furthermore, laser light supports the body's natural antioxidant protection system by supporting catalase and glutathione peroxidase production, which protect the body from free-radical damage.

The low-level laser also helps control unwanted bacteria while enhancing immunity and regeneration. Science has identified that pulsed laser light is more effective than straight laser light in promoting health.

Body tensegrity, tension and posture can all improve with the low-level laser, which together promote energy conservation, reduced strain on structure, and increased safety doing activities of daily living. And low-level laser up-regulation improves muscle responsiveness that can protect joints during movement, reducing the risk of injury.
