Tai chi is based on the idea of an energy, called qi, that runs through our bodies along energy lines or channels called meridians. The idea of qi, or life force, is central to the practice of Traditional Chinese Medicine (TMC). If it moves well, we are healthy and balanced. If the flow of the energy along the meridians is blocked or interrupted, or if the qi is weak, we can get ill in the body or in the mind.
The slow, deliberate movements in the practice are designed to stimulate the flow of this life force around our body and all the major organs in the body. Another Chinese system of movement, qigong, is based on the same idea of slow movement that is combined with slow breathing and meditation, and focusing on the present moment. It is believed that since blockages in the energy flow can cause illness, unblocking those blockages and stimulating the flowing of qi in the body can heal and also prevent illness and to keep us healthy and happy.
The same ideas are the basis of acupuncture, another treatment used in Chinese traditional medicine; in acupuncture needles are used to remove blocks and to help the life force to move in the body. Western doctors are sometimes suspicious of the idea of energies and meridians, but the health benefits can also be explained in Western medical terms.
For example, these ancient practices emphasize the correct alignment of the spine and good posture, and this can help with back pain or tension in the neck and shoulder area. Learning to move slowly and following the rhythm of your own breath is a good way to calm down and release stress in the body and the mind. The movements can also help the joints to move more freely and can increase flexibility.
The practices are also safe. Because the exercises are done slowly, there is no risk of injuring yourself even if you are not fit or flexible to begin with. Tai chi and qi gong are suitable for everybody, young or old, fit or not fit, and anyone can benefit from regular practice.
