Dermatology study on light therapy vs. near infrared therapy

The optimal NIR technology is done by LED as you are able to control the surface temperature. Also LED disperses over a larger surface area than a RED light halogen or laser. Another major difference between LED and halogen and Laser is the way light energy is delivered (optical power output – OPD). The OPD of LED Near is measured in milliwatts and laser and halogen is measured in watts. This allows LED to have a more gentler delivery as it will not damage tissue and will not have the same risk of accidental eye injury. Also with LED NIR disperses over a greater surface area give a faster treatment time.

NASA research has found that the NIR electromagnetic frequency band of energy penetrates deeply into the body and can have a healing effect on our individual cells.  For example, inside the mitochondria of every cell are receptors which respond to Near Infrared wavelengths.  The light triggers an increase in cell metabolism, protein synthesis (including collagen), and anti-oxidant activity (meaning the cells detoxify).  Additionally, it reduces inflammation and pain while simultaneously triggering growth and regeneration in the cells.

In short, light therapy affects mood, circadian rhythm and other body processes, while Near Infrared Therapy acts a pain reliever and cell rejuvenator – two VERY different forms of energy, but both beneficial.

Benefits of Near Infrared Therapy

Near Infrared Therapy falls on the spectrum of Infrared Light which is barely visible to the eye and is also the shortest infrared wavelength on the electromagnetic spectrum.  Infrared typically includes wavelengths from 700 nm to 1 mm.  Near Infrared light, however, falls in the spectrum of 700 nm to 2500 nm.
