- Natural lava sand
Innovative approaches to making warmth treatments extremely gentle, efficient and safe - that is the principle underlying Physiotherm’s low temperature infrared technology.
In order to ensure that the body is warmed completely and accommodates well, it needs time to accustom to the warmth. Blood flow, serving to regulate bodily temperature, needs to be distributed slowly and gradually, and the body’s core temperature should be increased slowly and continually without ever reaching the fever range. To achieve this, a ratio of the skin surface area in a thermally neutral environment to that under direct exposure to infrared radiation must be selected to prevent the arterio-venous shunts (AV shunts) from closing.
Physiotherm has achieved this with the low temperature infrared principle. Crucial to the effect is for two important components to be suitably combined: the patented infrared C ceramic heater filled with lava sand and the cabin design. At a cabin temperature of 30 °C, i.e. in a thermally neutral environment, the body absorbs warmth only from the back heater.
Lava sand: the mysterious energy from below the earth’s surface.
The patented ceramic heater, filled with lava sand, reliably provides a uniform, optimally suited radiation field not exceeding a radiation intensity of 100 mW/cm2 of skin in the infrared C range. By selecting the precise amount of skin surface, the AV shunts do not close even though sufficient thermal energy is absorbed by the body.
The warmth generated as infrared radiation is absorbed by the surface of the skin is continually transported to the interior of the body by the circulation of the blood supply. This results in a continuous, gradual increase of the body core temperature from the outset. The body begins gradually increasing the blood supply to the periphery (i.e. muscles and skin) in order to reduce the amount of “inner warmth”. In this way the body adapts to the situation. This gradual opening of the periphery to dissipate excess heat corresponds to the body’s natural temperature regulation response. The body is given the impression in effect that it has itself produced too much warmth. After about 10 minutes the body core temperature increases by 0.1 °C and perspiration also sets in. This effect may in fact be described as thorough warming from the inside outward, a phenomenon which the body takes to very well, as studies have shown. By simple thermal conduction deeply penetrating heat is additionally supplied locally to the back. During a normal session lasting about 30 minutes, the body core temperature increases by about 0.2 - 0.3 °C. There is absolutely no danger of causing an artificial fever when the cabin is used as recommended.
The Physiotherm Principle ensures local (i.e. by heat conduction to the back directly) and systemic treatment (i.e. stimulation of natural thermal regulation by a slight increase in the body core temperature) with infrared warmth in an especially gentle manner.
