Far-infrared rays

Far-infrared rays account for over half of the energy emitted by the sun. Far-infrared rays comprise wavelengths from 1 millimetre to the longest wavelength of visible light, from 5.6 microns to 14 microns wavelength. This range is also known as radiant heat. Far-infrared rays are readily absorbed by many kinds of matter and are thus effective in warming the substances on which they fall.Far-infrared rays have the ability to penetrate deeply (up to 1.5 inches) and permeate thoroughly into the hypodermic layer of a person's skin. Thus, it is possible to revitalize human cells and tissue by warming the body from the inside.

Negative ions

Negative ions are odorless tasteless molecules that are breathed into our respiratory system. High concentrations of negative ions can be found in nature in mountain forests, waterfalls, and beaches where people feel energized and invigorated, which helps relieve stress, alleviate depression, boost energy.

Hormesis effects of low level radiation

All living organisms evolved and exist in a sea of ionizing radiation, much of which is internal. It is a general belief that low doses of ionizing radiation produce detrimental effects proportional to the effects produced by high-level radiation. Over the past decades, however, some pioneer scientists reported that low-dose ionizing radiation is not only a harmless agent but often has a beneficial or hormetic effect. That is, low-level ionizing radiation may be an essential trace energy for life, analogous to essential trace elements.
