The lymphatic system is an often overlooked but crucial component of our immune system. It comprises of a network of lymphatic vessels and lymph nodes (also referred to as glands) that transport fluid, fats, proteins and white blood cells called lymphocytes to the bloodstream as lymph and removes microorganisms and other debris from body tissues, acting somewhat as a clean up system for the body. Unlike blood vessels which transport blood, however, the lymphatic vessels do not have a pump to shunt the lymph along but rely on the action of muscle movement to move the fluid along and valves that prevent the fluid from moving backwards. This is the reason that lying motionless is advised after a snake bite to prevent the toxin (which travels via the lymphatic system) from progressing towards the heart. 

• The primary way to improve lymphatic flow and reduce congestion is through regular exercise. Rebounding which is using a small trampoline is a very effective way to improve lymphatic flow as the rhythmic jumping action causes the one way valves to open and close encouraging lymphatic circulation. 
• Massage is also beneficial. Manual Lymphatic Drainage is a physical therapy in which the practitioner uses a range of specialised gentle pumping techniques to move the skin in the direction of the lymph flow.  
• Drinking plenty of water is vital as without adequate water, the lymph cannot flow properly. As well, avoiding foods with preservatives and other chemicals will lessen the burden on your body and its lymphatic system.
