In theory, when healthy, an abundant supply of ‘qi’ or ‘life energy’ flows through the body’s meridians (a network of qi channels throughout the body). The qi meridians can become blocked because of stress, overwork, poor diet, disease pathogens, weather and environmental conditions.
If the flow of qi in a meridian becomes blocked or is in short supply, then the body fails to maintain balance and harmony, and your body becomes sensitive to illness and disease.
In Traditional Chinese Medicine, it is believed that this qi is made up of two contradictory forms called Yin and Yang. Illness and disease are said to be the result of the unbalancing between Yin and Yang caused by factors acting on internal organs and manifesting themselves at certain points.
Traditional Chinese Medicine, with the view of holism, also considers the influence of seasonal and climatic changes on the human body. For example, in summer, Yang-Qi goes to the exterior of the body, leading to relaxation of the skin and muscles. In winter, since it is cold, Yang-Qi hides in the interior of the body, leading to the closing of the skin and little sweating.
When climate changes rapidly, it can often exceed the adaptive ability of the human body, resulting in a failure to correspond to the changes of the natural environments, causing an unbalancing of Yin and Yang, in turn, sourcing illness and disease.
