What is the lymphatic system and how lymphatic obstruction (lymphoedema) occurs Although you may have heard of the lymphatic system, few people really know much about it. However, it is an essential part of the body and is vital to our health. The lymphatic system is part of the circulatory and immune systems and includes a network of lymphatic vessels that carry a clear fluid called lymph to the heart. When the temperature is above 32C, thermochromic stones emit wavelengths (8-10 m), which are the most suitable frequencies and wavelengths for the human body. As a result, 92.1% of the far infrared rays in thermochromic stones can be absorbed by the human body. Far infrared rays penetrate deep into the body, helping to break down toxic substances and significantly reducing swollen lymph nodes. What does the colour of a thermochromic stone mean? Thermochromic gemstones are calibrated to have a pleasant blue or green colour at a normal resting peripheral temperature of 82 F (28 C) for the average person. As your body temperature absorbs the fat-burning far infrared rays, the stone distorts and reflects as an orange. When you detoxify your body, blood flows away from your skin and more towards your internal organs, thus cooling your fingers and causing the crystals to twist in the other direction, reflecting more sapphire. Negative ions increase the permeability of cell membranes, facilitating the absorption of tissue fluids into the lymphatic vessels. Thus preventing blockage of the lymphatic system.
