Explanation of some terms
Blood circulation – the circuit of blood through the body, from the heart through the arteries, arterioles, capillaries, venules and veins back to the heart. This is the blood flow that delivers oxygen and nutrients directly to cells while removing metabolic debris, toxins and carbon dioxide. A good blood circulation and microcirculation is an indicator for good quality of life. It can be influenced negativ for example by aging, improper diet or unhealthy lifestyle, physical or mental stress, improper hydration, a rare physical exertion, increased glucose level, increased blood pressure values. Healthy lifestyle plays crucial role for maintaining good blood circulation.
Brain stimulation - is a technique which uses electrical impulses , sound, light or magnetic fields to stimulate brain and synchronise brain waves with a periodic stimulus.
Brain wave – is defined as a rhythmic fluctuations of voltage between parts of the brain resulting in the flow of an electric current. Brain waves can be influenced by different methods including intranasal light application.
Continuous light – The output of light that is not interrupted during application time.
Diode – Electronic component made from semi-conductor materials.
Frequency – Refers to the number of light flashings per second.
Intranasal – Related to the nose interior. Intermittent light – Light with periods of flashing and eclipse
LLLT Variations of LLLT have gone by a variety of alternate names including low-power laser therapy (LPLT), soft laser therapy, low-intensity laser therapy, low-energy laser therapy, cold laser therapy, bio-stimulation laser therapy, photobiomodulation, photo-biotherapy, therapeutic laser, and monochromatic infrared light energy (MIRE) therapy. When LLLT is administered to so-called "acupuncture points", the procedure may be called laser acupuncture. When applied to the head, LLLT may be known as transcranial photobiomodulation, transcranial near-infrared laser therapy (NILT) , or transcranial low level light therapy.
Near Infrared (NIR)- A band of wavelengths (closest to red light) ranging from 700nm-1400nm on the electromagnetic spectrum having wavelengths that are longer than those of visible light. Humans are unable to see these wavelengths. NIR waves penetrate human tissue deeper than visible wavelengths and are able to penetrate through dense tissue like the skull or bones.
Photobiomodulation - ( LLLT low level laser-light therapy ) NAALT defines Photobiomodulation Therapy as "A form of light therapy that utilizes non-ionizing forms of light sources, including LASERS, LEDs, and broad-band light, in the visible and infrared spectrum. It is a non-thermal process involving endogenous chromophores eliciting photophysical and photochemical events at various biological scales. This process results in beneficial therapeutic outcomes including but not limited to the alleviation of pain or inflammation, immunomodulation, and promotion of wound healing and tissue regeneration."
Photobiomodulation different definition - A form of light therapy to repair tissue and reduce pain and inflammation that utilizes non-ionizing light sources. The visible light waves are between 400 –700 nm and near-infrared 700 – 1400 nm in the electromagnetic spectrum.
Polarization of light - The action of affecting light on such way that the vibrations of the waves assume a definite form with defined direction (or rotations) of waves. Laser light is always polarized. Light is wide spreading and absorbed in tissue differently depending on polarization and also other light parameters e.g. wavelength (color) of light.
Power of light – Quantity of photons emitted per second from the light source, measured in Joules per second – J/s ( Watt ).
Wavelength – The distance of one wave, measured between two successive points in the wave. Between the crest and the next crest, measured in nanometers (nm)
Well-being - the state of being comfortable, healthy, or happy.
Wellness - The quality of being in good physical and mental health especially when maintained by proper diet/nutrition, daily hydration of fluids, exercise, rest/proper sleep and controlling health risk factors preventing illness and prolonging life, as a result of deliberate effort.
