Indeed, your Lymphatic System aka internal "invisible shower", is sadly neglected in anatomy lessons and in general medicine. That is due to the disappearance within 4 hours of death, of the many teeny capillaries that are pathways of lymphatic fluid, transporting immune components into and throughout the body's tissue and carrying wastes and toxins out. Since most medical studies are on cadavers, we only "see" the larger ducts, nodes and lymphoid tissue of this very complex and permeating system, which includes over 850 lymph nodes, several large ducts, as well as the recently discovered Lymphatic Meningeal Vessel, which is the foundation of the glymphatic system, which is cleansing the brain during sleep. WHAT CAN WE DO TO HELP IT MOBILIZE? The best way to affect its natural process, is to replicate the oceanic rhythm of any Body of Water, and use pulsing, gentle, stretching circles, which begins to open the pathways in between the fascial layers. Scars, adhesions, tight garments, will all IMPEDE the movement of lymph fluid. If you have old injuries, surgeries, or odd swelling, congestion, puffiness, in any part of your body, that indicates STAGNANT LYMPH. If it is extreme, it can be lymphedema, which needs ongoing medical treatment. If it is moderate, or comes & goes, as in indigestion gas, bloating, headaches, fibromyalgia, MS, CFS, lyme, or other inflammatory disorders, LYMPH MASSAGE CAN DEFINITELY HELP!
