Near Infrared Light is Vital to Our Health*
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, however from a health perspective, this is absolutely incorrect. In the last 30 years there have been hundreds of scientific papers published on the beneficial aspects of near-infrared light (NIR). 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 and cell energy. 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 energy on the cellular level.
Near-infrared is missing in common white & full-spectrum LEDs.
Most white and full-spectrum LEDs consist of a blue LED (the energy pump) and fluorescent phosphors that cover the blue LED, transforming part of the blue light into longer wavelengths that create a yellowish light. The yellowish light combines together with the residual blue light to create a white light. This process causes LEDs to emit an excessive amount of blue light.
Blue has the highest energy in the visible part of the spectrum. Most white and full-spectum 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 wavelengths are not present in common LED bulbs.
Unfortunately, when using common white and full-spectrum LEDs, you end up with increased damage and decreased repair and regeneration. We have increased stress on the blue short wavelength part and we have reduced regeneration and repair on the red 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.
Light is misunderstood and the most overlooked part of the health equation.
Molecules that absorb light are found in your mitochondria. Mitochondria, found in most cells, can be considered the power generators of the cell, converting oxygen and nutrients into cellular energy ATP (adenosine triphosphate). ATP is the fuel your cells need for all of their varied functions, including metabolism. The light absorbing molecule is the last step before the ATP is finally produced in the mitochondria. Absorbed light in a wavelength range between 570 nm and 850 nm is able to boost energy production, especially in cells when energy production is depleted.
Natural sunlight is loaded with red and near infrared light, light exposure that’s not balanced like the sun — can be damaging to human biology.i.
