The Importance of the Lymph System to Health
Most of us know that a sedentary lifestyle causes health to decline, and yet a large part of the population of all ages do not move or exercise regularly. Sitting at a desk, lounging on the sofa, driving, lying in bed and so on. The modern world encourages us to be sedentary as technology has us rooted to our devices, work has most of us chained to our desks and we become lethargic and inactive.
Our body systems only work effectively when we exercise, move and breathe. Why is movement so vital to the physical body? One aspect to consider is the seemingly invisible lymphatic system, whose function is vital to optimum health. The lymph system is everywhere in the body, it is the drainage system for waste, moving it towards our cleansing organs. However, unlike the heart and vascular system, there is no pump in the lymph system and yet there is more lymph fluid than there is blood. The lymph system only works through exercise and movement (muscular contractions). Slight muscle movement will start to activate the lymph system, however a person who frequently exercises will help the system function in a more efficient way.
Movement and Disease
If the lymph fluid does not flow freely through the lymph node ducts towards the organs for ‘cleaning’ and ‘recycling’, then they become clogged up like a blocked drain. The dirty fluid can then become infected and will start causing a decline in health. Lymphedema is caused by a blockage in the lymph system, and cancer cells can be distributed by the lymph system too. Add to this poor nutrition, those eating a diet of processed foods, fizzy drinks and booze, the lymph system struggles more and this weakens the immune system further.
Exercise and movement have a huge effect on how our body recovers from illness and disease. In times of recovery we need to flush out toxins as quickly as possible, to return to a stable state of health. Without movement, the duration for recovery is lengthened. Read more in my article on Tai Chi and qi gong for injury recovery.
Effective Physical Movements
Tai Chi and qi gong movements are often described as ‘hydraulic movements’, with expanding, compressing and spiralling motion that connects the whole body. This is combined with diaphragmatic breathing, intention and purpose in a slow and relaxed manner. This total body movement is seen as the most effective exercise for enhancing the function of the lymph system when performed correctly and frequently.
Not all movements are equal however, the body needs to go through a complete range of motion. Walking and moving your arms and legs through your daily routine is not an effective form of exercise. These are seen as habitual postures and movements. Exercise should take you outside of this. That said not all Tai Chi and qi gong movements are equal either, as it depends on the knowledge and experience of your instructor in body mechanics.
In Tai Chi and qi gong training, emphasis is placed on movements that use the ‘Kua’. There’s no direct translation or body part in English for this area, which covers the inguinal groove through the pelvis, hip bones, hip joint and into the lower back. By increasing movement in the Kua, this aids softness, flexibility, strength and fluidity, which helps with the expand, compress and spiralling motion that activates the lymph system. The inguinal groove area also holds the largest amount of lymph nodes in the body, which is why Kua movements are of importance and quite unique to Tai Chi and qi gong training.
The lymph system is not the only beneficiary of this pumping action, the circulation, cerebrospinal fluid, synovial fluid in the joints, cellular fluid and internal organs all work more efficiently when the body exercises.
Move more, move better….. As the renowned Dave Hedges of Wild Geese Martial Arts once said “Motion is lotion”.
