Near Infrared Light (NIR)


Near Infrared Light is Vital to Our Health 

ir . .

Solid-state LEDs are long-lasting and save energy, however critical components of the biological impact of these bulbs have essentially been ignored.

Physicists think that infrared radiation is just thermal waste, but from the viewpoint of a physician, this is absolutely not true. In the last 30 years there have been hundreds of scientific papers published on the beneficial aspects of near-infrared light. You cannot feel near-infrared as heat nor see it, but it has a major beneficial impact in terms of health especially for your eyes. Most importantly, NIR helps prime the cells in your retina for repair and regeneration and helps reduce the risk of macular degeneration and is vital to the production of ATP (adenosine triphosphate) cell energy.

Near-infrared is missing in common white & full-spectrum LEDs.

Most LEDs emit an excessive amount of blue light. Blue has the highest energy in the visible part of the spectrum. Most LEDs lack the essential, counterbalancing healing and regenerative red and near-infrared frequencies.

The repair and regenerative part of the spectrum is not found in the blue wavelengths.

Blue wavelengths create ROS (Reactive Oxygen Species). ROS describes a number of reactive molecules and free radicals that have long been known to be a component of the killing response of immune cells to microbial invasion. When generated in excess, ROS can cause damage.

Tissue regeneration and repair results from red and infrared wavelengths that are not present in LED bulbs.

Unfortunately, when using common white LEDs, you end up with increased damage and decreased repair and regeneration. We have increased stress on the short wavelength part and we have reduced regeneration and repair on the long-wavelength part. This is a serious problem. We don’t have this kind of light quality in nature. This has stress consequences in the retina and it has consequences in our endocrine system.

“LED light exposure that is not balanced like natural, full-spectrum sunlight that is loaded with the critical red parts of the spectrum — is damaging to your biology.”
