Excerpt from (Tsai & Hamblin, 2017) "Infrared (IR) is a type of electromagnetic radiation, including wavelengths between the 780 nm to 1000 µm. IR is divided into different bands: Near-Infrared (NIR, 0.78~3.0 µm), Mid-Infrared (MIR, 3.0~50.0 µm) and Far-Infrared (FIR, 50.0~1000.0 µm) as defined in standard ISO 20473:2007 Optics and photonics -- Spectral bands (Vatansever F, 2012). Several studies have reported that IR can improve the healing of skin wounds, photoprevention, relieve pain, stiffness, fatigue of rheumatoid arthritis, ankylosing spondylitis, potentiate photodynamic therapy, treat ophthalmic, neurological, and psychiatric disorders, and stimulate the proliferation of mesenchymal and cardiac stem cells (Vatansever F, 2012), (Tsai SR, 2015) (Barolet D, 2015). Soccer players have used FIR emitting clothing (density of 225 gm², 88% far IR radiation emitting polyamide 66 Emana yarn (PA66) fiber, 12% Spandex, emissivity of 0.88 and power emitted of 341 W/m? at 37°C at 5–20 µm wavelength range). These garments were used for 10 hours as sleepwear over three successive nights to relieve delayed-onset muscle soreness 48 h after an intense plyometric exercise session (Loturco I. 2016)"
