The lymphatic fluid is a clear liquid that contains the body’s T- and B-cells. The lymphatic system, as Dr. Morton Walker refers to it in his book Jumping for Health, is the “metabolic garbage can of the body. It rids you of toxins, such as dead and cancerous cells, nitrogenous wastes, fat, infectious viruses, heavy metals, and other material cast off by the cells.” CJ Puotinen outlined how modern living and clothing, such as bras, and lack of exercise lead to constriction of the lymph system or allow it to lag and become clogged. (“Lymphatic Immune Support,” May/June and July/August 2000 issues of Well Being Journal.)
When you rebound, you are helping your cells metabolize, cleanse and renew, and you are helping your lymph system to pump and drain out the body’s waste. Unlike the cardiovascular system, with the heart as a pump, the lymph system does not have a pump. Lymph is moved like a hydraulic pressure system…. The lymph tubes a…re filled with one-way valves that only open up, or allow drainage toward the center of the body. When pressure below the valve is greater than above ( moving downward on the rebounder) the valves are forced open so the fluid can flow.” There are only three ways for the lymph system to “pump” and cleanse: exercise, which helps muscular contraction; massage of the tissues it serves to get it to pump back into the pulmonary circulation; and gravitational pressure with its resultant internal massage.
Rebounding provides all three ways of removing waste from the cells. Dr. Walker sums it up: “Then arterial blood enters the capillaries in order to furnish the cells with fresh tissue fluid containing food and oxygen. The bouncing motion effectively moves and recycles the lymph and the entire blood supply through the circulatory system many times during the course of the rebounding session.” And the joy of it all is that you don’t even have to exert yourself to get these benefits. The eldest of the elderly can do this, as well as the handicapped person, and the arthritic.
