3. Research about infrared produced by bamboo charcoal
Infrared, a electromagnetic wave with wavelength between 0.78um and 300um(near infrared: 0.78～2.5um；middle infrared：2.5～25um；far infrared 25～300um),has the property that can reach the acceptant object directly unaffected by air. The energy level transition type of near infrared is the double frequency absorption of O-H、N-H、C-H key, while middle infrared is the group vibrancy and running of molecule, and far infrared is molecule running and crystal case librating.
　 The health care principle of bamboo charcoal far infrared: 1)heating effect: when shined by infrared, the temperature of skin and some organization below skin will raise, vas expands, the speed of blood accelerates, the quantity of oxygen contained in blood raises, blood circulation and the process of metabolism accelerate. One side, it can accelerate alimentation. On the other side, some metabolizing rubbish inside the body, like carbamide, lactic acid, dissociation fatty acid, fattiness below skin, freeness group will be oxidation decomposed. Besides, toxicant inside the body caused by environment pollution will be discharged. It’s the process that resumes physiology balance and eliminates the pathology. So it has the function of reduce retiredness, improve the quality of sleeping, and strengthen memory. What’s more, it helps to adjust nerve and reduce intention and inhibition. 2) Activation effect: moisture takes up 70% in human body and the combination of moisture has important influence for its activation. Infrared has capability of waking molecule energy, reducing hemal sticky, strengthening the rebirth ability of cell and immunity, delaying caducity. 3) knead function: The high frequency librating made by infrared has the knead function to skin cell. It can improve the sweat gland function, accelerate the excretion of rubbish, dredge pores, and reduce the burden of kidney. In addition, for the absorption of nutriment is accelerated, it assists to reduce keratinization, making skin more delicate, less furrow. Man’ skin, as a organism, is of high absorption rate and heat passing rate. Once accepting infrared, it can approach to endothelium quickly, especially for which wavelength is 4-14um. Except for keeping warm, it also has the function of restraining bacterium, deodorization, accelerating blood circulation and so on. Absorbing heat radiating outside, and releasing by molecular energy level transition, infrared with wavelength between 2.5-30um , and the infrared which wavelength is 4-14 um relating close to the growth of living things can cause blood circulation, with the function of keeping warm, health care and accelerating the process of metabolism. It has remarkable effect for the symptom of arthralgia and insomnia.
