Bioaccumulation – the process of storing toxins in the body.
Blackbody – is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.
Cardiovascular System – is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from cells in the body to nourish it and help to fight diseases, stabilize body temperature and pH, and to maintain homeostasis.
Cellular Perfusion – is the process of a body delivering blood to a capillary bed in its biological tissue.
Conduction – the heating of an object through direct touch.
Convection – an object putting out heat into the air.
Electromagnetic Fields (EMF) – are defined as fields that are produced by electrically charged objects, which then affect the behaviors of charged objects in the vicinity of its field. The entire EMF field is a result of the combination of the electric field and the magnetic field. Electromagnetic fields are the result of any electronic device with active circuits running through it.
Electromagnetic Radiation – is a form of energy released by electromagnetic processes. In physics, all EMR is referred to as light, but colloquially light often refers exclusively to visible light, or collectively to visible, infrared, and ultraviolet light.
Emissivity – the emissivity of the surface of a material is its effectiveness in emitting energy as thermal radiation. Thermal radiation is light, but for objects near room temperature this light is infrared and isn’t visible to human eyes.
Energy – in physics, energy is a property of objects, transferable among them via fundamental interactions, which can be converted into different forms but not created or destroyed. Work and heat are two categories of processes or mechanisms that can transfer a given amount of energy.
Far Infrared – is represented in the infrared spectrum from 4 microns to 1000 microns.
Hyperthermia – is elevated body temperature due to failed thermoregulation that occurs when a body produces or absorbs more heat than it dissipates.
Immune System – is a system of biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism’s own healthy tissue.
Infrared Light – is invisible radiant energy, electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometers.
Integumentary System – is the organ system that protects the body from various kinds of damage, such as loss of water or abrasion from outside. The system comprises the skin and its appendages (including hair, scales, feathers, hooves, and nails). The integumentary system has a variety of functions; it may serve to waterproof, cushion, and protect the deeper tissues, excrete wastes, and regulate temperature, and is the attachment site for sensory receptors to detect pain, sensation, pressure, and temperature. In most terrestrial vertebrates with significant exposure to sunlight, the integumentary system also provides for vitamin D synthesis.
Lymphatic System – is part of the circulatory system, comprising a network of lymphatic vessels that carry a clear fluid called lymph directionally towards the heart. Unlike the cardiovascular system the lymphatic system is not a closed system. The human circulatory system processes an average of 20 litres of blood per day through capillary filtration which removes plasma while leaving the blood cells. Roughly 17 litres of the filtered plasma get reabsorbed directly into the blood vessels, while the remaining 3 litres are left behind in the interstitial fluid. One of the main functions of the lymph system is to provide an accessory route for these excess 3 litres per day to get returned to the blood.
Micron – is an SI derived unit of length equaling 1×10−6 of a meter (SI standard prefix “micro-” = 10−6); that is, one millionth of a meter (or one thousandth of a millimeter, 0.001 mm, or about 0.000039 inch). The symbol µm is sometimes rendered as um if the symbol µ cannot be used, or if the writer is not aware of the distinction. The micrometer is a common unit of measurement for wavelengths of infrared radiation as well as sizes of cells and bacteria and is also commonly used in plastics manufacturing.
Nanometer -is a unit of length in the metric system, equal to one billionth of a meter. The nanometer is also commonly used to specify the wavelength of electromagnetic radiation near the visible part of the spectrum: visible light ranges from around 400 to 800 nm.
Near Infrared – is represented in the infrared spectrum from .7 microns to 2.0 microns.
Peak Emission Wavelength – The wavelength of visible or invisible light usually measured by nanometers or microns.
Radiant Energy – is the energy of electromagnetic radiation.
Resonant Frequency – In physics, resonance is the tendency of a system to oscillate with greater amplitude at some frequencies than at others. Frequencies at which the response amplitude is a relative maximum are known as the system’s resonant frequencies, or resonance frequencies. At these frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores vibrational energy.
Thermal Radiation – is electromagnetic radiation generated by the thermal motion of charged particles in matter. All matter with a temperature greater than absolute zero emits thermal radiation.
Vasodilation – the dilation of blood vessels, which decreases blood pressure and improves circulation.
Volatile Organic Compound – are organic chemicals that have a high vapor pressure at ordinary room temperature. Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air. For example, formaldehyde, which evaporates from paint, has a boiling point of only –19 °C
Wien’s Law of Displacement – states that the black body radiation curve for different temperatures peaks at a wavelength inversely proportional to the temperature.
