Infrared light penetrates your body into the cellular level, charging your molecules and raising your core body temperature. This allows your heart to pump faster and to pump more oxygenated blood to your capillaries. When this happens it speeds up your body’s most important bodily function–essential to life–cellular perfusion.
Cellular perfusion is your body’s mechanism for replenishing your cells with fresh oxygen and removing carbon dioxide. When this process is sped up, it actually allows for your body’s cells to act much faster in the healing process.
In a recent study done by NASA called “NASA Light Emitting Diode (LED) Medical Program – Progress in Space Flight and Terrestrial Applications”, it was found that near infrared light “absorbed by the cells stimulated the metabolism in muscle and bone as well as skin and subcutaneous tissue.” Which promotes faster wound healing and human tissue growth.
