Heal Your Body with Photobiomodulation
Dr. Mercola interviews the expert: Dr. Michael Hamblin
Photobiomodulation therapy has important implications for health that many are still under-informed about. In this interview, photodynamic therapy researcher Michael Hamblin, Ph.D., who is an expert in this area, sets out to improve our understanding of this important field.
Near-Infrared Helps Fuel Your Body
You probably know that the food you eat is converted to generate ATP. But the mechanism of ATP production can also be stimulated in response to near-infrared exposure, which triggers the mitochondria to produce additional ATP. So, it could be said that your body is fueled by both food and sunlight.
More specifically, light allows your body to use food more efficiently. In other words, light helps the cells make the best use of whatever food they have, and improves the generation of energy. “For instance, light seems to combine very well with modest amounts of exercise,” Hamblin says.
The ideal way to receive most of this exposure would be to simply go outside, exposing as much skin as possible. Unfortunately, there are many areas where this would be impractical in the winter. This is where therapeutic light devices can be helpful.
The optimal wavelength for stimulating COO lies in two regions, red at 630 to 660 nm and near-infrared at 810 to 830 nm. Multiple studies have also failed to detect a difference between red light (660 nm) and near-infrared (810, 830).
So, the mid-600s and all of the wavelengths in the low 800s appear to have the same biological impact.
What this means is that the red light at 630-660 nm will provide the same mitochondrial benefits as the near-infrared range of 810 to 830 nm. Curiously enough, 730 nm does virtually nothing. One theory is that the absorption spectrum of COO has two peaks: one in the mid-600s and one at around 800.
