| Popis: | 93 It is believed that some specific spectra of Far-infrared （FIR）(e.g. 4-14μm) have positive influence on the human physiological responses. However, there is no convinceful evidences. The main aims of this research are to study the transferring ability of Far-infrared into biological tissues and the enhancing ability of Far-infrared to blood flow. Trough the animal experiments, we have found the following responses: 1. FIR energy can be transferred deeper than near-infrared in vitro pig skin model. 2. FIR enhances core temperature less than near-infrared in vivo mouse model. 3. Skin blood flow on radiated area (forearm) increases after either FIR or near-infrared radiation. On non-radiated area (finger), the blood flow does not change significantly. In short, FIR energy can transferred deeper than near-infrared, but has less influence to body temperature. Therefore, FIR is more effective and has lower risk of heatstroke if we use FIR as a health care tool. |
