What is the difference between Near InfraRed and Far infrared frequencies?Updated a year ago

Near Infrared frequencies of sun energy also make an important contribution to natural healing. These specialized wavelengths help with skin surface to approximately 3cm deep penetration. They help with skin problems like psoriasis, atopic dermatitis, eczema and rashes, etc. Near wavelengths will improve micro blood circulation and generate the natural production of Nitric Oxide. Lastly it will enhance mitochondrial wellness and cell energy. Therasage uses Near frequencies in all of its full spectrum devices and has enhanced our Near frequency application in our Therasage360 Plus portable sauna.
