Radiant vs. conductive
Our product's infrared energy produces relatively cool temperatures (45 ºC - 48 ºC). Will not burn or scald.
Heat Transfer and Electromagnetic Radiation
There are three phenomena through which energy can be transmitted: electromagnetic radiation, conduction, and convection. While all three energy forms in varying degrees are present in the application of Doctor Detox’s F.I.E energy products the primary energy form utilized is electromagnetic radiation. Unlike conduction and convection, electromagnetic waves need no material medium for transmission. As with the electromagnetic radiant energy of the sun, which travels through the atmosphere to warm the earth, the radiant energy emitted by our horse therapy products for therapeutic purposes, are emitted to and absorbed by the body in a natural process.
All of the components of the electromagnetic spectrum, regardless of frequency, also have in common the typical properties of wave motion. The wavelengths range from millionths of a centimeter to many kilometers. The wavelength and frequency are important in determining heating effect, visibility, penetration and other characteristics of the electromagnetic radiation.
Infrared Radiation
An understanding of Far-Infrared ("FIR") firstly requires an understanding of radiant heat. Radiant heat is also called infrared energy. Radiant heat is simply a form of energy that heats objects directly through a process called conversion, without having to heat the air space in between.
FIR is the emission of energy as electromagnetic waves in the portion of the spectrum just beyond the limit of the red portion of the visible spectrum.

The Far-infrared segment of the electromagnetic spectrum is divided into 3 segments by wave length, measured in microns or micrometers:
(one micron = 1/1,000,000 of a meter):
0.076 - 1.5 microns = Near Infrared (NIR);
1.5 - 5.6 microns = Middle Infrared (MIR); and
5.6 - 1000 microns = Far or long wave infrared (FIR).
The Human Body's Energy Absorption Spectra
Our bodies radiate and absorb infrared energy through the skin at 3 - 50 microns with a concentration of energy output at 9.4 microns. The FIR radiation of Doctor Detox products emit about two-thirds of its output in the MIR band width from 2 - 5.6 microns, for deeper penetration, with the balance of output in the FIR band, from 5.6 - 25 microns with that part of the output spread around the 9.4 micron pivot point of peak human output. This distribution maximizes the higher penetration of the middle-band waves and combines them with the long waves that produce a resonant absorption amplification of healthy tissue output.

Use in China
The following is summarized from Therapeutic Heat and Cold, 4th Edition, ED. Justus F. Lehmann, M.D., Williams and Wilkins, Chapter 9 or concluded from the data therein.
Generally it is accepted that heat produces the following desirable therapeutic effects:
It increases the extensibility of collagen tissues
Tissues heated to 45 ºC and then stretched exhibit a non-elastic residual elongation of about 0.5 Ü 0.9% that persists after the stretch is removed which does not occur in these same tissues when stretched at normal tissue temperatures. Thus 20 stretching sessions can produce a 10 Ü 18% increase in length in tissues heated and stretched.
This effect would be especially valuable in working with ligaments, joint capsules, tendons, fasciae, and synovium that have become scarred, thickened or contracted.
Such stretching at 45 ºC caused much less weakening in stretched tissues for a given elongation than a similar elongation produces at normal tissue temperatures.
The experiments cited clearly showed that low-force stretching can produce significant residual elongation when heat is applied together with stretching or range-of-motion exercises, which is also safer than stretching tissues at normal tissue temperatures.
This safer stretching effect is crucial in properly training competitive athletes so as to minimize their "down" time from injuries.
It decreases joint stiffness directly
There was a 20% decrease in stiffness at 45 ºC as compared with 33 ºC in rheumatoid finger joints, which correlated perfectly to both subjective and objective observation of stiffness.
Any stiffened joint and thickened connective tissues should respond in a similar fashion.
It relieves muscle spasms
Muscle spasms have long been observed to be reduced through the use of heat, be they secondary to underlying skeletal, joint, or neuropathological conditions.
This result is possibly produced by the combined effect of heat on both primary and secondary afferents from spindle cells and from its effects on Golgi tendon organs. The effects produced by each of these mechanisms demonstrated their peak effect within the therapeutic temperature range obtainable with radiant heat.
It produces pain relief
Pain may be relieved via the reduction of attendant or secondary muscle spasms.
Pain is also at times related to ischemia due to tension or spasm which can be improved by the hyperemia that heat-induced vasodilation produces, thus breaking the feedback loop, in which the ischemia leads to further spasm and then more pain.
Heat has been shown to reduce pain sensation by direct action on both free-nerve endings in tissues and on peripheral nerves. In one dental study, repeated heat applications led finally to abolishment of the whole nerve response responsible for pain arising from dental pulp.
Heat may both lead to increased endorphin production and a shutting down of the so-called "spinal gate" of Melzack and Wall, each of which can reduce pain.
It increases blood flow
Heating of one area of the body produces reflex-modulated vasodilations in distant-body area, even in the absence of a change in core body temperature; i.e. heat one extremity and the contralateral extremity also dilates: heat a forearm and both lower extremities dilate; heat the front of the trunk and the hand dilates.
Heating of muscles produces an increased blood flow level similar to that seen during exercise.
Temperature elevation produces an increase in blood flow and dilation directly in capillaries, arterioles and venuies, probably through direct action on the smooth muscles. The release of bradykinin, released as a consequence of sweat-gland activity, also produces increased blood flow and vasodilation.
Whole-body hyperthermia, with a consequent core temperature elevation, further induces vasodilation via a hypothalamic-induced decrease in sympathetic tone on the arteriovenous anastomoses. Vasodilation is also produced by axonal reflexes and by flexes that change vasomotor balance.
It assists in resolution of inflammatory infiltrates, edema and exudates
The increased peripheral circulation provides the transport needed to help evacuate edema which can help end inflammation, decrease pain and help speed healing.
More recently, it has been used in cancer therapy
This is a new and experimental procedure.
It shows great promise in some cases when used properly.
American researchers favour careful monitoring of the tumour temperature; whereas, the successes reported in Japan make no mention of such precaution.
Far-Infrared healing is now becoming the leading edge in the care of soft tissue injuries to promote both relief in chronic and intractable "permanent" cases, and accelerated healing in newer injuries.
Localized Far-infrared therapy using lamps tuned to the 2 Ü 25 micron waveband is used for the treatment and relief of pain by over 40 reputable Chinese Medical Institutes.
Researchers reported over 90% success in a summary of Chinese studies that assessed the effect of infrared therapy on:
Soft tissue injury
Lumbar strain
Periarthritis of the shoulder
Sciatica
Pain during menstruation
Neurodermatitis
Eczema with infection
Post-surgical infections
Facial Paralysis (Bells' Palsy)
Diarrhea
Cholecystitis
Neurasthenia
Pelvic infection
Pediatric pneumonia
Tineas
Frostbite with inflammation
