The underlying scientific principles of light therapy
Our light therapy devices emit light with special wavelengths. These wavelengths of the visible and electromagnetic spectrums range from 600 to 1000 nm. This part of the spectrum is able to penetrate deep into the subcutaneous tissue and influence damaged cells. When used properly, this type of stimulation has no health-damaging effects. The human eye perceives it as red light.
Medical treatments that utilize light sources are also referred to as phototherapy. Applying the red light spectrum revealed the best results in tissue recovery and reduction of swelling and pain.
Human cells contain specialized photoreceptor molecules called cytochrome c oxidase, which are enzymes of the mitochondrial respiratory chain. Mitochondria are organelles that provide our cells with energy. This happens in the respiratory chain and is connected to a series of biochemical reactions. Phototherapy starts with the absorption of a photon, a vital signal for the beginning of the process, and ends with the synthesis of a molecule called adenosine triphosphate (ATP), which supplies the energy needed for normal cell functions. For this reason, the respiratory chain is one of the most important processes in our cells.
