“Far Infrared Therapy (FIR) is a type of low energy therapy using light in the far infrared spectrum for the treatment of a health problem. FIR or infrared therapy uses the part of the sunlight spectrum whose wavelengths fall below the visible red light. The most beneficial lights are those whose wavelength is near this red light. FIR’s radiant heat can penetrate up to 3.5 inches beneath the skin.”
“Infrared therapy also stimulates the hypothalamus, which regulates the production of neuro-chemicals involved in sleep, mood, pain sensations, and blood pressure. Far infrared therapy has been shown to have positive effects in treating arthritis; muscle pain; shoulder and joint stiffness; venous disease; and immune insufficiency as it treats the whole body and not a specific symptom.”
This is really big, especially for older people. Pajamas made from these metal infrared emitting oxides are just what is needed. Remember, trust but verify.
