Far Infrared Health Care
When people fell sweat when the weather hot . The sweat vaporizes and the body temperature drops. When it is cold , the body heats up through exercise , body temperature is maintained at 37 ° C.
When the temperature is too low , blood vessels constrict and feel cold, so heating equipment is necessary. The use of far infrared radiation can make constricted blood vessels dilate , accelerate blood circulation , promote human metabolism , so that the body exhaust . This is the effect of far infrared health care.
Infrared has various characteristics, in the selection of special attention to what kind of infrared is the best for health care. When the body receives infrared heat , it is first absorbed by the skin, at this time , the heat transferred to the body by high-efficiency infrared radiation and far-infrared radiation is not the same .
Fig.1 shows the spectral emissivity curves of high-efficiency infrared and far-red emitters.
Fig.2 shows the spectral absorption curve of the skin . According to the effect of infrared health care , the energy absorbed by the body can be determined .
Fig.3 shows the give-and-receive relationship of energy when the body is irradiated with infrared rays of a high-efficiency infrared emitter at 500℃.
Therefore , Fig.4 shows the relationship between skin and infrared rays .
Therefore , high efficiency infrared radiation energy , skin absorption characteristics are also very good.
The radiation energy of far-infrared radiation is less than that of high-efficiency infrared radiation , energy of giving water to the body is also lower .
The human body can be said to be 70% water . High efficiency infrared radiation can provide energy to human tissues and cells. Although far infrared can also supply human tissues , effect of cellular energy is good, but in terms of body perception , it is less than high-efficiency infrared, high-efficiency infrared is a hot feeling , far infrared makes people feel soft warmth .
