When Bio-ceramic material is impregnated into the fibres of the rug and placed next to the skin of the equine Far Infrared radiation is produced. The primary source of energy required to stimulate FIR emissions comes from the equine's body. The ceramic nanoparticles in the rug become ‘perfect absorbers’ maintaining their temperature at adequate levels then offering FIR back to the equine's body. This ensures there is a constant emission and absorption of FIR to the equines skin, regulating temperature and preventing the opportunity of overheating when applied in ambient temperatures up to 25 degrees.
