The tourmaline mineral (a precious natural mineral) at the bottom of the sock releases a natural energy through far-infrared (invisible waves of energy) to stimulate the foot and leg, effectively improving blood and lymph circulation and relieving arthritis. It also helps the body eliminate harmful waste, inflammatory cells and toxins. Laboratory tests showed that far-infrared therapy is an effective and safe remedy for pain and inflammation. It can penetrate deep through the layers of the skin, to the muscles, nerves and bones effectively. Since infrared therapy enhances and improves circulation in the skin and other parts of the body, it can bring oxygen and nutrients to injured tissues, promoting healing. It helps ease pain, relieve inflammation, and protect against oxidative stress. How it does it: Far-infrared therapy has proven to be versatile for treating many pain types, including chronic, gout, bursitis, arthritis, osteoporosis, tendonitis, fibromyalgia, neuropathy, plantar fasciitis and more. It help with relief of pain, reduction of stiffness, control of inflammation, maintenance of joint mobility, and prevention of deformity. From the perspectives of ancient East, there are various acupoints on the soles of the human body, which correspond to different organs of the human body. Frequent massage of these acupoints can relieve the pressure of human organs, help the organs to discharge accumulated toxins, promote blood and lymph circulation, reduce body fluid accumulation, relieve swelling, lymphatic blockage and tissue edema. Our product works to unblock energy pathways that have been clogged up with toxins by stimulating specific reflex areas on the feet that correspond to different organs and the energy pathways in the body. This optimizes the functioning of the organs by improving blood flow to them and increasing lymphatic fluid movement to get rid of toxins. There are many toxins in the environment such as, pollution, radiation, chemicals, pesticides and medication. This causes accumulation of toxins and energy blockages in our bodies. When toxins accumulate, our bodies warn us in the form of pain, swelling, weight gain and other symptoms. It can aid a weight loss program you are on, even if you are not exercising regularly and eating a healthy balanced diet then still 80 percent amount of reflexology is going to get you to the weight you want.
