Medicallyinfrared ray with length more than 2.5 micrometer called far infrared ray.Theinfrared ray with wave length 4 to 14 micrometer can match our body radiationand produce warming effect.It will promote our metabolism,so it is called "thelight of life". FIR has following obvious functions to our bodyhealth:

Microcirculationis the blood circulation of capillaries between arteriole and venule. The basicfunctions are for interchange of material between blood and organization cell,nutriment transportation(include nutri ents and Oxygen),wastes discharging (carbon dioxide and metabolin). So microcirculation is "second heart" of ourbody. With functions of FIR,temperature of skin and hypodermis increase,expanding capillaries. Most material in blood are water.With big water moleculebecoming small water cluster, water molecule liquidity in capillaries increase alot. Also the decrease of blood viscosity and blood fat will make veinsmooth.This is also a important factor on improving microcirculation.

Once infraredlight touch our body,it can cut down long chain between big molecule in ourbody(30 to 40pcs water molecule),and form small molecule with 5 to 6 watermolecule, so it will increase the quantity and speed of water molecule thatpermeate cell membrane.

On one hand,itcan clean cell,strengthen discharge of toxin.On another hand, it will improveenergy exchange of oxygen and nutrients, as well as calcium ion activity of cellmembrane and inside cell.

Scientistscalled tourmaline energy stone as "natural generator of negative ion", so it has3 good reputation: “environmental police”, ”air vitamin”, “atmosphere longevityelement”
