Scientists have been able to discover why these ancient but simple set of exercises provide such healing benefits to the body-mind. Traditional exercise helps us to loose weight and build muscle. Whenever we exercise, our bodies produce chemicals that are not produced when we are still. Most exercises cause the body to damage some muscle to some extent without being noticed. When this is repaired the muscle grows back stronger. The chemicals produced by the body are the medicine that is used up fully by the muscles to heal.
When Qigong-Taichi is practiced, the movements are so gentle that muscles are not damaged. Since there is no damage to the muscles that needs healing, the healing chemicals are conserved. So, the healing chemicals are stored in three reservoirs or dantian of the body for balancing and energizing the body. Therefore, our bodies produce the very medicine needed to heal itself. Normal exercises produce them but are fully used up. Tai Chi releases the healing chemicals but conserves them.
Another important ingredient in Qigong-Tai Chi is the utilization of oxygen’s ability to heal. During traditional exercise, we breathe hard and increase our intake of oxygen. The hard work put in causes cells in the muscles to become oxygen starved. Most of the oxygen intake is used up by the cells. On the contrary, slow and gentle movements in Taichi-Qigong stores and supplies oxygen to different body organs evenly. Oxygen is not sucked up by oxygen starved cells as in the case of traditional work outs. The deep breathing provides the much needed healing oxygen. Part of Tai Chi practice is to breathe deeply and slowly while performing the gentle movements. The deep breathing provides more oxygen than the muscles actually need. The extra oxygen is available to the other cells all the time. This also helps the heart, brain and other organs to receive a double dose of oxygen and the healing chemicals, increasing the healing power of both.
Various studies in Qigong conducted by the Chinese and other international medical bodies have shown a remarkable change in nervous system, lymphatic system, digestive system, circulatory system, immune system, cardiac system and other systems and thereby increase oxygen and blood supply to various organs.
