Physiotherm’s Steadiflow elements emit the ‘vital rays’. All humans send and receive Far Infrared waves. The range of Far Infrared waves generated by the human body is 6 to 20 microns. The optimal micron output range is between 7 and 14 microns, which is very close to the resonant frequency of a water molecule. This similarity makes sense since our bodies are almost 80% water. This range, sometimes called "Vital Rays" appears to have special regenerative effects on the body.

Physiotherm’s Steadiflow elements allow for optimal performance well within this vital wave range of 7 to 14 microns with a good portion of wavelengths at 9.4 microns, the frequency at which a water molecule resonates or vibrates. This vibration causes a release of cellular toxins such as mercury, aluminium, cholesterol and other toxic gases such as sulphur and formaldehyde. This optimal micron output also allows for deeper penetration of Far Infrared heat.
