“When absorption of light by a tissue chromophore takes place, covalent bonds cannot be broken because of the energy of the photons involved. However, the energy is sufficient for the first excited singlet state to be formed, and this can undergo intersystem crossing to the long-lived triplet state of the chromophore. The long life of this species allows reactions to occur, such as energy transfer to ground state molecular oxygen to form the reactive species, singlet oxygen. Another photochemistry pathway that can occur after the absorption of a red or NIR photon is the dissociation of a non-covalently bound ligand from a binding site on a metal containing cofactor in an enzyme. The most likely candidate for this pathway is the binding of nitric oxide to the iron-containing and copper-containing redox centers in unit IV of the mitochondrial respiratory chain, known as cytochrome c oxidase.” – Dr M. Hamblin, “Mechanisms of Low Level Light Therapy”, Harvard Medical School.
The nasal cavity is rich with blood capillaries. There are five major arteries that connect to the nasal cavity, while the Little’s area
is known to be a frequent site of nasal bleeding. It is known to have more capillaries per sq cm than even the brain and most organs of the body. Given the rich supply of blood and the thin, permeable membrane that separates blood from the exterior in the nasal cavity, this area is an excellent spot for blood irradiation. Being just 3 inches from the brain, with little barrier, it is also an excellent source for direct brain stimulation.
